When determining whether an argument is inductive or deductive, you must assume that all premises are true. Then you must see whether the conclusion would probably or necessarily follow. You are not determining whether the premises are true but judging the kind of reasoning based on the argument’s structure. In other words, you “deduce”.
Example Inductive:
In 2010, an oil drilling rig leased by British Petroleum (BP) was damaged from an explosion, and oil began gushing out of a broken pipe into the Gulf of Mexico. In the six months after the accident, more than 600 sea turtles have been found dead along the Gulf Coast. Since this is a much higher amount than what is typical for the season, it is reasonable to conclude that the sea turtle deaths are a result of the oil spill.
The issue is whether the 600 sea turtle deaths are caused by the 2010 British Petroleum oil spill. The conclusion is that the 600 sea turtle deaths are caused by the 2010 British Petroleum oil spill. The first premise is that in 600 sea turtles have been found dead along the Gulf Coast within six months of the 2010 British Petroleum oil spill. The second premise is that 600 dead sea turtles is a much higher amount than what is typical for the season. This is inductive.
Example Deductive:
Why wouldn’t a woman consider herself a feminist? Even my husband calls himself a feminist. If he can call himself that, then every woman should be able to call herself that. Every woman should consider herself a feminist.
The issue is whether every woman should consider herself a feminist. The implied conclusion is that every woman should consider herself a feminist. The first premise is that my husband calls himself a feminist. The second premise is that if my husband considers himself a feminist, then every woman should consider herself a feminist. This is a deductive argument.

Hi Professor and Class!
First example:
It’s sunny in Singapore. If it’s sunny in Singapore, then he won’t be carrying an umbrella. So, he won’t be carrying an umbrella(Fieser, 2018).
This example is a deductive argument. It has logical strength because it’s sunny so he won’t be carrying an umbrella. Both premises are valid to the conclusion that comes after “So”. It passes the test of validity because it’s sunny in Singapore and if it’s sunny he won’t be carrying an umbrella provide support for the conclusion.

Second example:
Every time I’ve walked by that dog, it hasn’t tried to bite me. So, the next time I walk by that dog it won’t try to bite me(Fieser,2018).
This example is an Inductive argument. Its strength depends on its premises. For example, the argument would be stronger the more times the person walked by the dog and didn’t get bit. Its logic to think the dog has never tried to bite him, so he won’t next time. The argument could get stronger or weaker if certain circumstances changed in the premises. Inductive arguments can change based off of different evidence and deductive arguments don’t.

Hi Professor,
I’ll give it another shot!
This example from the book I believe is deductive because it has two true premises and then a true conclusion. Everyone who owns a car needs car insurance is premises 1 and Joe just purchased a car is the 2nd premises. Conclusion would be he needs insurance.
EX: Everyone who owns a car needs car insurance. Joe just purchased a car. Therefore Joe needs car insurance.
I think the example below is an example of an Inductive argument because just like the one above the argument could get weaker or stronger if things changed in the premises.
EX: The cat scratches me everytime I walk by it. Tomorrow when I walk by the cat will scratch me.

Hello Ashley, thank for your repost.
Remember, when identifying premises the first premise is premise (without the s); the same for the second.
The first argument is positively deductive. The second argument is inductive since there is a good chance that that cat will probably scratch when you walk by since it has occurred so many times in the past.
We are learning that there are two crucial thinking skills. In the first, inductive reasoning, one observes a set of facts from several viewpoints. Leaving out some facts or adding new ones might lead to some particular interpretation. Inductive reasoning helps to make a generalized conclusion based on individual reflections or datasets. For example, the observation, “this tree has a shadow” is an individual observation. The generalized conclusion that “all trees have shadows” helps us approach some specific problems and derive an answer.
In deductive reasoning, you go the other way around. You start at some general premise. This could be anything from mathematical physics such as “the sum of the internal angles of a quadrilateral is 360°. This is the way critical thinking works. You find out how to solve the questions with the help of your teammates. Here again one needs to check opinions based on your assessment of the situation. Also, if you study the assumptions that led to the situation, you might discover a lot of fallacy.
Determine if the following are inductive or deductive:
1. If God exists there is good in the world. God exists, so there is good in the world. 2. Many inexplicable phenomena have eventually been explained by science, so
consciousness will eventually have a scientific explanation. 3. Since every action has an equal and opposite reaction, this action will have an equal and
opposite reaction. 4. Which of the two argument types (i.e. deductive or inductive) seem to add something new
to the premises? Which seems to have its conclusion contained within its premises?

Hello Professor Sheffield and class,
Inductive Example
“The sun rose yesterday, the day before yesterday, the day before the day before yesterday, and 1,000,000 days before that. Therefore, the sun will rise tomorrow” (Johnson, 2016, pg.5).
The issue is that the sun will rise tomorrow. The claim is that the sun will rise tomorrow. The premise is that the sun rose yesterday, the day before yesterday, the day before the day before yesterday, and 1,000,000 days before that. According to Facione (2016), “We use inductive reasoning skills when we draw inferences about what we think is probably true” (pg. 176). This is inductive reasoning because it is probable that the sun will rise tomorrow, but it is not for certain.
Deductive Example
“All muscles are made out of living tissue. All humans have muscles. Therefore, all humans are made out of living tissue” (Wilson, 2016).
In our textbook Facione (2016) discusses how we use deductive reasoning to “assume truth of a set of beliefs to a conclusion which cannot be false if those beliefs are true” (pg. 156).This is an example of a deductive argument. The conclusion is that all humans are made from living tissue. The first premise is all muscles are made from living tissue. The second is that all humans have muscles, and therefore all humans are made from living tissue. If we assume that the two premises are true, then the claim is true as well.

Hello Professor Sheffield and class,
Here are examples of inductive and deductive reasoning from opinion articles. I apologize for misunderstanding the instructions.
Inductive Example
“The economy isn’t driven by stock prices or corporate profits — it only works because of workers. If they’re doing well, the economy is doing well” (Linden, 2020).
The claim is that if workers are doing well, the economy is doing well. The first premise is that the economy isn’t driven by stock prices or corporate profits. The second is that the economy only works because of workers. According to Facione (2016), “We use inductive reasoning skills when we draw inferences about what we think is probably true” (pg. 176). This is inductive reasoning because it is it is probably true that the economy is driven by workers, and not the stock prices or corporate profits, however, it is not for certain. This argument would need more solid evidence to prove that the claim is true. I do not believe this argument has a strong validity.
Deductive Example
“Amazon is making a killing from this crisis. Almost literally. Jeff Bezos’s net worth has grown by more than $24 billion (https://www.theguardian.com/technology/2020/apr/15/amazon-jeff-bezos-gains-24bn- coronavirus-pandemic) since the crisis started since everyone is at home trying to avoid going to the store and ordering everything online” (Cummings, 2020).
The is that Amazon is making a killing from this crisis. The first premise is that Jeff Benzo’s net worth has grown by more than $24 billion since the crisis started. The second premise is that everyone is at home trying to avoid going to the store and ordering everything online. In our textbook Facione (2016) discusses how we use deductive reasoning to, “assume truth of a set of beliefs to a conclusion which cannot be false if those beliefs are true” (pg. 156). This is deductive reasoning because if it is true that Jeff Benzo’s net worth has grown more than $24 billion since the crisis, and everybody is ordering everything online, then Amazon is most definitely making a killing from the crisis. I do believe this argument has strong validity. The author provided us with the amount of money Benzo’s next worth has grown since this crisis started, and it is highly probable that a lot of people are avoiding the stores right now to avoid contracting COVID-19.

Brittney, thank you for reposting. And no worries. These days most of us have so much to think about.
The first argument is absolutely inductive; the second deductive. I know for sure about the second one since I have Amazon stock and it is going up (YAY).
Can you see the different ways the premises support the conclusion in the following arguments?
Deductive All philosophers have a brain. Bob is a philosopher. Therefore, Bob has a brain.
Inductive Most philosophers have a brain. Sam is a philosopher. So, Sam probably has a brain.
This distinction describes how the premises support the conclusion. In deductive arguments, the truth of the premise(s) guarantees the conclusion. That is, it is impossible for the conclusion to be false if we assume the premises are true in a good/valid deductive argument.
In inductive arguments, the premise(s) provide probabilistic support. That is, it is improbable, but possible, that the conclusion is false in good/strong inductive arguments.
Argument 1 is a deductive argument because the conclusion must follow if we assume the premises are true. In example 1, it is impossible for the conclusion (i.e. Bob has a brain) to be false if the premises are assumed true. So, it is a valid deductive argument.
In Argument 2, it’s improbable that the conclusion is false if we assume the premises are true.

It’s possible, but unlikely, that Sam doesn’t have a brain.
Identify the following arguments as inductive or deductive
1. In my experience, most people are happier when they have the Epicurean goods of friends, self-sufficiency, and time for reflection. Therefore, I think you will probably be happier if you focus on getting these three goods.
2. You cannot achieve peace of mind until you recognize what is under your control and what isn’t under your control, and then not worry about what isn’t under your control. What others think of you isn’t ultimately under your control precisely because it’s their thinking. Therefore, don’t worry about what others think of you (Stoicism).
3. All tigers are animals. Tigger is a tiger. Therefore, Tigger is an animal. 4. Humans usually use new technologies in times of war to destroy instead of build. The
atomic bomb is a great example. Therefore, we will probably use strong artificial intelligence to destroy in times of war (if we ever invent it).

Hello Professor Sheffield,
Argument 1:
The claim is that if you focus on the three goods listed that you will probably be happier. The premise is that most people are happier when they have the Epicurean goods of friends, self- sufficiency, and time for reflection. I would say this argument is inductive because it is probable that having goods like friends, self-sufficiency, and time of reflection would make a person happier, therefore, if we assume that the probability that the premises are true, then the conclusion is most likely true as well, but it is not certain.
Argument 2:
The claim is that you should not worry about others think of you. The first premise is that you cannot achieve peace until you recognize what is under your control, and what isn’t under your control, and then not worry about what isn’t under your control. The second premise is that what others think of you isn’t ultimately under your control precisely because it’s their thinking. I believe this example is deductive reasoning. This is because if we assume that the two

premises are in fact true, then the claim that you shouldn’t worry about what others think of you is true as well.
Argument 3:
This argument is deductive reasoning. The claim is that Tigger is an animal. The first premise is that all tigers are animals. The second is that Tigger is a tiger. If both premises are true, then that would make the claim true as well.
Argument 4:
The claim is that we will probably use strong artificial intelligence to destroy in times of war (if we ever invent it). The first premise is that humans usually use new technologies in times of war to destroy instead of build. The second is that the atomic bomb is a great example. This is an inductive argument because the premises are probably true, but it is not certain that if we do invent strong artificial intelligence, we would use it to destroy in times of war.

Week 4 Discussion
Inductive Argument:
We are currently under going a pandemic in today’s world because of the Coronavirus. I know that you guys are very familiar with this. This virus has caused many different hardships challenges around the world, including people being out of work. When the U.S. hit an all time high in the number of cases of the virus, it was discovered that over 40 million Americans have filed for unemployment (Cohen, 2020). Since the unemployment cases have never been that high, it is reasonable to conclude that those cases are a result from the high rise of Coronavirus cases.
The issue is whether the 40+ million unemployment cases are causes behind the high number in the Coronavirus cases. The conclusion is that the 40+ million unemployment cases are caused by the high rise of Coronavirus cases. The first premise is that there was over 40 million Americans filing for unemployment once America was hit hard with the Coronavirus. The second premise is that 40+ million unemployment cases is extremely high and is not normal on a regular basis. This is inductive.

Chloe, thank you for your post for this week and providing examples of both deductive and inductive arguments. Also, thank you for providing a story from the New York Times.
I would absolutely agree that the first argument on COVID-19 is probably true but not necessarily and, as a result, makes it inductive. The second argument (I like the argument very much!), is deductive. As an aside is it strong or valid?
Identify the following arguments as inductive or deductive:
1. We are going to have at least one day in which the temperature rises above 100 in Austin because this has happened in Austin for at least the last 300 years.
2. Consciousness is either a physical thing or a nonphysical thing. Since it is not a physical thing, it must be nonphysical.
3. Since the universe is like a watch, it is probably designed. 4. There are only two people in this house: Blaise and Catherine. Neither wear glasses.
Therefore, Blaise doesn’t wear glasses.

Hello class,
My first example is a letter to the editor of the Washington Post titled, Maryland’s online option for receiving mail-in ballots could overwhelm election workers. In this letter, Gina M. Angiola explained the issues that may arise in Maryland come election time. Her argument was essentially that:
Online ballots have to be hand copied by election officials. Last year it took Montgomery County 5 days to count their ballots. This year there will be more mail in ballots than last year (because of COVID). We are only allowed 10 days to count all votes. So only the citizens that are in rural areas and have no other option but online voting should be able to place online votes.
I labeled this argument as inductive. It is inductive because although the facts stated were noteworthy, there could be different factors that could change the conclusion. Facione and Gittens (2016) explain, “As long as there is the possibility, however remote, that a highly probable conclusion might be mistaken even though the evidence at hand is unchanged, the reasoning is inductive” (p 176). Due to COVID, the government might hire more election officials to process the online ballots therefore making it beneficial for more citizens to participate in online voting. Since I was able to find a counterexample I do not feel that the argument is valid.
My second example I found was an op-ed on USA Today. Paul Rosenzweig argued why William Barr is an unethical lawyer. One of the articles arguments was that:
William Barr is an attorney general. All lawyers are bound to follow the ethical rules adopted by the State Bar Association where they are licensed to practice law. Barr has been dishonest and deceitful, and has also interfered with the administration of justice. Therefore, Barr’s license to practice law should be revoked.
I labeled this as deductive. This is deductive because all three premises rely on each other and it is a logical argument. “Deductive reasoning moves with exacting precision from the assumed truth of a set of beliefs to a conclusion which cannot be false if those beliefs are true” (p 159). Assuming that all the premises were true, the conclusion followed accordingly and the argument was valid.

Danin, thank you for posting for this week and providing arguments from the Washington Post editorial.
Yes, I can go with the first argument being inductive some people living in Maryland should “probably” submit an online ballot. The second argument.
So many students what is the purpose of logic? Well let’s think about for a moment since a branch of philosophy )critical thinking) is a form of logic.
Logic is a tool for discovering the truth and why things are connected through lines of inference. These lines of inference allow us to make determinations on truth and falsehood, validity and invalidity, and much more. Most arguments are composed of two important parts: premises and conclusions which delineate deductive and inductive arguments.
It is often best that students do a formal analysis (determining premise(s) & conclusion) for arguments since it not only reinforces argument analysis skills but also provides the best means for correctly identifying fallacies.
Determine the type of fallacies for the following: Indicate the issue first and then premise(s) and conclusion followed by the type of fallacy.
#1 Smoking is harmful to your health. Smoking is bad for you.
#2 Smoking causes lung cancer, heart disease, stroke, and other cardiovascular diseases.

Good Morning Professor and Class,
A deductive argument is an argument that is intended by the arguer to be deductively valid, that is, to provide a guarantee of the truth of the conclusion provided that the argument’s premises are true(Cline 2019). This point can be expressed also by saying that, in a deductive argument, the premises are intended to provide such strong support for the conclusion that, if the premises are true, then it would be impossible for the conclusion to be false. All arguments are either valid or invalid, and either sound or unsound; there is no middle ground, such as being somewhat valid.
The author Facione (2016) does a great job of breaking down the definition as, “assume truth of a set of beliefs to a conclusion which cannot be false if those beliefs are true” (pg. 156).
Inductive Reasoning:
All cars in this town drive on the right side of the street (https://image-seeker.com/s/?q=street) . Therefore, all cars in all towns drive on the right side of the street (https://image-seeker.com/s/?q=street)
This is inductive reasoning because it makes the claim from the specific to the general- which is the cars on the right side and the rule of the street (https://image-seeker.com/s/?q=street) .
Strength: The conclusion is true. Since the premise is base on the fact that cars drive on the right side of the street (https://image-seeker.com/s/?q=street) . The possibility of the conclusion being wrong as in driving on the right is not there. Therefore the strength of the argument is good.
Deductive reasoning:
All cats have a keen sense of smell. Fluffy is a cat (https://image-seeker.com/s/?q=cat) , so Fluffy has a keen sense of smell.
This is a deductive argument because its premise is based on general or universal and explains a specific case.

The argument is valid because Fluffy being a cat (https://image-seeker.com/s/?q=cat) makes him have a keen sense of smell. The conclusion is base on the premise that cats have a keen sense of smell. The chances of the conclusion being illogical from the premise are not there. Therefore, it is a valid argument.

Exampe 1
“There is not a single era in U.S. history in which the police were not a force of violence against black people. Policing in the South emerged from the slave patrols in the 1700 and 1800s that caught and returned runaway slaves. In the North, the first municipal police departments in the mid-1800s helped squash labor strikes and riots against the rich. Everywhere, they have suppressed marginalized populations to protect the status quo” (Kaba, 2020).
This argument is deductive. The argument is: “there is not single era in the U.S. history in which the police were not a force of violence against black people”. The supporting sentences provide data from different eras and areas in the U.S. that the police existed. Without each of these supporting reasons, the argument’s claim that “there is not a single era” would fall flat, as only one era or one moment in history would be used as an example. The more examples of specific times in history the police were weaponized, the stronger the speaker’s claim. This argument passes the test of validity. The supporting reasons all match the conclusion and none of them are questioned for accuracy.

“In Tanzania alone, 1.4 million people are living with HIV and in Africa as a continent as much as 26 million people are suffering from this disease… In Sub-Saharan Africa women represent 58% of all people living with HIV or AIDS and for women in their reproductive years this is the most common reason why they die, either because of illegal abortions or from complications during childbirth… The failure to provide young people proper sex education and information about and access to contraceptives in countries like Tanzania is resulting in devastating consequences” (Ring, 2016).
This argument is inductive. The argument is “the failure to provide young people proper sex education and information about and access to contraceptives in countries like Tanzania is resulting in devastating consequences”. The supporting sentences are used to back up this claim. They can also stand alone- without each other- in order to still provide adequate support to the claim. This argument passes the test of strength. The supporting arguments give little room for the conclusion to be counter-argued.

Hello Dijana, thank you for providing arguments from either a news feed or a blog.
I concur that the order of your arguments, i.e., deductive first, and then inductive.
Determine the fallacy of each of the following:
1. We should either pay our teachers better salaries or admit that we don’t care about our children’s education. (False Dilemma)
2. Of course she’s rich! Just look at that diamond ring she is wearing. (Hasty Generalization) 3. I love visiting Wyoming because I enjoy traveling in the West. (Begging the Question) 4. He went to college and came back a pothead; college corrupted him. (Post Hoc)

Deductive Reasoning
“We just learned yesterday that an Amazon executive resigned over an unfair firing of whistleblowers who are trying to keep themselves and their workers safe. Amazon does not need much of an excuse to fire us; it happens all the time. Anyone can be fired without any notice or reason- being a few minutes late, getting written up for not making rate, demanding more gloves and masks (Cummings, 2020).
The conclusion is that anyone can be fired without notice or reason. The first premise is being a few minutes late for the work shift. The second premise is getting written up for not making rate. The third premise is asking for more essential supplies like gloves and masks. Deductive reasoning is, “to identify and secure elements needed to draw reasonable conclusions” (Facione & Gittens, 2016, p. 34). The opinion in this article uses deductive reasoning because the writer feels that Amazon fires their employees very quickly over what she believes to be minor reasons.
Inductive Reasoning
“Australia is an early test case of how the world’s affluent societies will bend, or buckle, or rebuild under the pressure of temperature changes likely to hit the rest of the well-off world later in the century” (Mack, 2020).
This article is inductive reasoning. The writer believes that because of temperature changes that are happening in Australia are creating fires and causing structural damage, the rest of the world will experience these changes as well. “Decision making in terms of uncertainty is considered inductive reasoning” (Facione & Gittens, 2016, p. 176). How can the author assume that just because Australia is experiences natural disasters because of temperature changes that the rest of the countries in the world will fall subject to the same conditions? This opinion does not yield certainty.

Hello Jasmine, thank you for posting this week and providing examples of inductive and deductive arguments.
Regarding your deductive argument: When I read the argument consider that what you indicated at the at the first premise, “being a few minutes late for the work shift”, that’s not really the premise. Premises are complete sentences or overweight statements. For example the actual premise is anyone can be fired without any notice or reason. A second premise is anyone can be fired being a few minutes late. Another premise is anyone can get written up for not making rate. In the final premise is anyone can be fired who demand more gloves and masks. Does this make sense? Do you have a better understanding?
For your inductive argument: you did not identify the premises for that particular argument on Australia.
In the following, identify the type of fallacy.
1. “America: love it or leave it.” 2. “Since scientists cannot prove that global warming will occur, it probably won’t.” 3. “If we pass laws against fully automatic weapons, then it won’t be long before we pass laws
on all weapons, and then we will begin to restrict other rights, and finally we will end up living in a communist state. Thus, we should not ban fully automatic weapons.”

Hi Professor and Class,
Inductive Reasoning
When I visited this company last Monday, all employees had ties. Today is Monday and the employees are wearing ties. The employees wear ties every Monday.
This statement is an example of inductive reasoning because it concludes that the company employees wear ties on Mondays. According to Chamberlain (2020), an argument is strong if both its premises and conclusion are true; also known as a cogent argument. It can be observed that it is customary for employees to wear ties on Mondays, hence the premises are true. This is also true for the conclusion that the employees will have ties next Monday. Therefore, the argument is strong. Doyle (2019) asserts that inductive reasoning accounts for repeated patterns, from which it narrows down to make a hypothesis that can be evaluated.
Deductive Reasoning
Bachelors comprise of unmarried men. Socrates is a bachelor. Socrates is an unmarried man.
Sound statements require that both premises of an argument must be true for it to be valid. According to Facione and Gittens (2016), a deductively valid statement is made up of two premises that are true and are joined to make a true conclusion. The example above has true premises, hence the conclusion is also true. The argument is therefore valid.

Inductive Example
“The EU insists that if the UK wants tariff-free access to the EU’s enormous internal market, then it must make commitments to obey certain EU laws” (McGee, 2020). This example is an inductive argument because it requires new premises to determine the conclusion. If UK makes commitment to obey EU laws, then UK can access EU’s internal market for free; but we do not know what UK will do. I think this argument is valid we can determine the conclusion on the facts.
Deductive Example
“Indian Matchmaking itself offers a window into the lifestyles of an elite class of Indians who can enlist the service of a top-tier matchmaker, and in some cases, fly them to the other side of the world. This is not something regular families do, so status is already built into the narrative” (Sangal, 2020). This is a deductive example. Regular family does not offered matchmaking in India. Indian matchmaking is only for elite classes. If you are offered matchmaking, you must be in the elite class. This argument is valid because the conclusion matches the premise.

Ann, thank you for your post for this week and identifying deductive and inductive arguments from CNN news.
Let me just tell you that when you use abbreviations, for example EU, one must first write out what those two letters mean and then in the rest of the sentence or paragraph they can use the abbreviation. For example European Union needed to be written out first.
Is your argument “the EU insist that if the UK want carefree access to the EU’s enormous internal market…” Even after reading the entire article I could come up with premises and conclusion. Also you did not identify any premises or conclusion. So it’s difficult for me to determine whether it is a doctor or not.
I also read the article from Sangal, and I came up with several premises and several conclusions.
I would recommend that you reread both of those articles and provide the premises and the conclusion. That will help to determine whether it’s inductive or deductive or not.
Determine the fallacies in the following:
1. “Government is like business, so just as business must be sensitive primarily to the bottom line, so also must government.”
2. “A book is pornographic if and only if it contains pornography.” 3. “We should not believe President Clinton when he claims not to have had sex with Monica
Lewinsky. After all, he’s a liar.”

Hello,
Example 1: John is ill. If John is ill, then he won’t be able to attend our meeting today. Therefore, John won’t be able to attend our meeting today (Fieser, 2018).
This is an example of deductive argument. Both premise of this argument is valid to the conclusion. The argument passes the Test of Logical Strength, because John is ill and he won’t be able to attend the meeting today. According to the textbook, a valid argument passes the Test of Logical Strength (Facione,2016).
Example 2: The police said John committed the murder. So, John committed the murder. (Fieser, 2018).
This is an example of inductive argument. It is inductive because there could be other factors that could change the conclusion. The argument is invalid. The police made an educated guess.

Hello Professor and class,
Distinguishing between Inductive and Deductive Reasoning
Inductive Reasoning
Trump’s personal and political interests are aligned with Russia’s.
In the electoral context, Trump is perfectly fine with Russia attacking U.S. democracy if it benefits
7/30/20, 8:14 PM Page 24 of 48
him. This is of course not to say Trump is fine with Russian bounties on U.S. troops. He very well might sincerely believe it isn’t happening.
Rather, the point is that Trump has reasons for generally not wanting to probe too deeply into stories that might expose Russian intentions toward the U.S. in a particularly malign light when he may be hoping to gain from more Russian undermining of U.S. democracy. Those reasons prioritize self-interest over the national interest. That’s a key context for explaining his sheer disinterest in getting to the bottom of the bounties.
This portion of this article indicates that it is an Inductive argument because the writer’s premises are not based on concrete facts or proven truths but rather lean towards a possible truth. They certainly seem to support the claim that President Trump is ignoring some information about Russia’s interference because it may serve his own political interests in the long run. The writer may actually be shading light on something that is possibly true and therefore readers, may be required to seek further information about this claim before ruling it as true or false. The writer’s premises seem truthful, make logical sense are relevant to his claim, and seem to support the claim.
Inductive reasoning as explained by Facione & Gittens (2016) simply means that as long as there is a possibility, regardless of how remote it is, then a conclusion is probably true.
Deductive Reasoning
I have no patience with those declaring workers cast from their jobs by COVID-19 will shirk work if given unemployment benefits. As if “they” need to be cattle-prodded out of their lethargy.
If we’re so desperate to reignite our economy, let’s recall that more than 70% of it is based on consumer spending and that millions of those “consumers” are going broke and facing imminent eviction. Homeless folks don’t make great customers.
Let’s give people work rebuilding our infrastructure, not punish them for events beyond their control. That’s the job of an effective government.
The above statement reflects a Deductive Argument whereby the writer is highlighting that our economy largely depends on consumer spending to thrive and therefore unemployment benefits will ensure people have purchasing power, thus be able to reboot our economy after the COVID- 19 pandemic is over. I say it is a Deductive argument because the first premise is a solid fact that can easily be proven to be true which proves the truth of the conclusion that unemployment benefits will have a positive impact on our economy in the long run.

Melissa, thank you for your post for this week and providing the various arguments. Good examples and they are correct.
Some arguments offer one or more examples and support overgeneralization. Consider this: women in earlier times were married very young. Julia in Shakespeare’s Romeo and Juliet was not even 14 years old. In the middle ages, 13 was the normal age of marriage for Jewish woman. And doing Roman times, many Roman women were married at age 13 or younger.
How could this argument be improved?
Derek Weatherby took a job at Schrock’s, a grocery store in St. Louis, to help pay his way through college. As a student debt mounted, he took a break from school, planning to go back when his financial situation improved. But with the economy still stagnant years after the financial crisis, Derek has found that many of the other employees at Schmocks are college graduates themselves, some with degrees from prestigious schools. It seems that lots of college graduates can’t find work that pays any better than the job that Derek already has.

Professor and Class,
Example 1:
All of the managers at my office have associates degrees. Therefore, you must have an associate’s degree to become a manager.
This is an example of inductive reasoning. In this example, the worker is assuming that because all of the managers at her office have associate degrees, that in order to become a manager there, you must have an associates degree as well. In this example, the person speaking is using the information that is available to them, even if it is not complete. Based upon this information, the person will try to determine the most likely outcome.
Example 2:
My boss said the person with the highest sales would get a raise at the end of the month. I have the highest sales, so I am looking forward to a raise.
This is an example of deductive reasoning. In this example there are two statements that have true pieces of information. There is also an assumption that is based on the two pieces of information. As long as the first two pieces of information are true, the assumption should also be true.

The first example you provided, “All of the managers at my office have college degrees. Therefore, you must have a college degree to become a manager.” comes directly from a website that identifies the argument. This is not what you were asked to do.
Reconstruct the following argument. Identify those that are instances of a correct inductive form and those that are fallacious. If the background knowledge required to evaluate the argument is missing, discuss what would be needed.
Both the American Medical Association and the American dental Association have formally endorsed fluoridation of drinking water. Fluoridation promotes dental welfare and is not generally harmful to people’s health.

Hello Everyone,
Before starting this assignment I did research on deductive and inductive arguments because I felt like I was lacking some knowledge. It’s a bit confusing at first but after breaking the definitions down and reading multiple examples I finally understand the concept. “An inductive argument is an argument that is intended by the arguer to be strong enough that, if the premises were to be true, then it would be unlikely that the conclusion is false” (Deductive and Inductive Arguments). “A deductive argument is an argument that is intended by the arguer to be deductively valid, that is, to provide a guarantee of the truth of the conclusion provided that the argument’s premises are true” (Deductive and Inductive Arguments). Taking those definitions and developing examples.
Example Inductive:
Michael Phelps says olympic system neglects mental health. Phelps managed to earn 28 olympic metals across five games labeling him as the poster child. Phelps stated “I don’t think anyone jumped in to ask us if we were OK. As long as we were performing, I don’t think anything else really mattered” (Futterman, M., 2020). After years of competing in the olympics he grew to learn he wasn’t the only one facing these challenges. Since then many Olympians have come forward to explains they also have struggled with mental health. “The metaphor I like to use is when it comes to the spectrum of sports performance, we think the top is hitting a grand slam to win the game and the bottom is striking out, when
7/30/20, 8:14 PM Page 28 of 48
” Reply &
in fact the actual bottom is not wanting to be alive” (Futterman, M., 2020).
The issue is Olympians are put under a great amount of stress neglecting their mental health. Over the course of their training and performance more olympians speak up about the stress they are put under which neglects their mental health. Since they individuals are held to higher standards and their bodies are pushed to the extreme, it is reasonable to conclude that the olympics is damaging peoples mental health.
Example Deductive:
Going through elective college classes can be challenging due to the lack of motivation. But, political science all of the quizzes have been easy. Therefore, the final exam will be easy. I have taken every quiz and received an 90% or better. My classmates are also passing each quiz with a B+ or higher.
The issue is that every quiz has been easy to where everyone is passing the class with ease. The implied conclusion is that the final exam will be easy. The first premise all of the quizzes in political science have been easy. The second premise is the final exam will be easy, taking into consideration my classmates and I are all passing each quiz with a B+ or higher.

Ashlyn, thank you for providing both deductive and inductive arguments from the New York Times.
It is understandable that deductive and inductive are difficult but if you had an opportunity to review the video I provided on the differences, I think you would understand a bit better. The differences between the two are quickly identified: For example, a deductive argument a conclusion that is supported by the premises to be determined as true. Whereas an inductive argument the conclusion based on the premises is probably true.
In your examples of deductive and inductive arguments, can you detail the premise(s) and the conclusion for each please. You forgot that part. Thank you.
Decide whether the following argument is an acceptable inductive generalization or a fallacy. Identify the premises and the conclusion of the argument. In the case of a fallacy, explain what is wrong. Discuss what sort of additional background information, if any, is needed.

Hi Professor and Class,
Deductive Example
All humans are mortal. Socrates is a human, therefore, Socrates is a mortal.
In this example, the speaker asserts that the premises are true and therefore, the conclusion must be true. This passes the test of validity. A deductive argument is valid such that a conclusion must be true if the premises are true. A valid argument passes the logical strength test
Inductive Example
After studying only one night beforehand, I’ve aced the last three quizzes in this class. So even though I’ve studied only one night for this class’s upcoming quiz, I’ll probably ace it, too.
In this example, the person is presenting their evidence that by studying only night before an has led to them acing the last three quizzes, thus, these premises support the probable truth of the conclusion. The argument is inductive because there is a good chance that the person will ace the next quiz, after studying one night beforehand, since it has happened for all the three past quizzes.

Christine, thank you for providing both a deductive and an inductive argument from the New York Times.
Decide whether the following argument is an acceptable inductive generalization or a fallacy. Identify the premises and the conclusion of the argument. In the case of a fallacy, explain what is wrong. Discuss what sort of additional background information, if any, is needed.
At the University of Pennsylvania, psychiatrists conducted a study to determine the social factors that affect the well-being of coronary patients. There were 93 patients in the study; slightly more than 50% of them had pets of some kind (dogs, cats, fish, and one iguana). At the end of a year, one third of the patients who did not own pets died, but only three animal owners succumbed. The psychiatrists concluded that pet ownership may have a positive effect on the health of humans.

Hello Professor and class,
Inductive Argument example:
“All sunflowers are attracted to bees. Therefore, all bees attract sunflowers.”
According to Facione and Gittens (2016), inductive type of reasoning is used when inferences are drawn about what may be probably true, which in this case is bees attracting sunflowers.
Based on logical strength, this argument presents a fact, which is, “All sunflowers are attracted to bees” and then a conclusion is made about the argument, which is, “Therefore, all bees attract sunflowers.” The conclusion here is based on the fact that “All sunflowers are attracted to bees.”
In regard to inductive reasoning, the observation of facts is first and then the conclusion is made based on those facts (Shin, 2019).
Deductive Argument example:
7/30/20, 8:14 PM Page 31 of 48

“All Syrian women cook and clean. My sister Sara is a Syrian woman, so she cooks and cleans.”
This is a deductive argument because this argument states a fact that is true, which is, “All Syrian women cook and clean” and the conclusion has to be accepted, which is, “My sister Sara is a Syrian woman, so she cooks and cleans.” This makes the argument valid because Sara being a Syrian woman cooks and cleans, which is based on the fact that, “All Syrian women cook and clean.”

Hi Juliana,
The examples you provided were great! You were precise with the connection of the example and left no room for openness! Some examples I came across were open-ended, where within the example of “If the river continues to rise, then the carpet will get wet”, anything can make the carpet wet, which left the statement open. However with your examples, it is known that bee’s are attracted to sunflowers, which is a precise inductive argument!
Good post!

For at least 30 years, even as oil has more than doubled and tripled in cost, economic advisors to both major political parties have agreed that the best way to make consumers conserve energy is to impose taxes, ranging from $0.50 per gallon of gas to five dollars a barrel on imported oil. Higher taxes on gas and oil use will be the best way to encourage conservation.

Hello!
Deductive and inductive arguments refer to the process by which someone creates a conclusion as well as how they believe their conclusion to be true (Wilson, 2016).
Deductive argument is to think of syllogisms like: If A=B and C=A, then B=C; For example: If the river continues to rise, then the carpet will get wet (Gittens, 2015). The strength of this example can pass as weak because the carpet necessarily can be wet from anything inside the home, like a leaking sink or if the toilet overflowed.
Inductive argument uses a set of specific observations to reach an overarching conclusion; For example: My neighbor’s cat hisses at me daily. At the pet store, all the cats hiss at me. Therefore, all cats probably hate me (Wilson, 2016). The logic behind this example can pass as weak as well because if a cat is unfamiliar with someone, naturally they will be on offense.

This newspaper article summarized various opinions regarding COVID and going back to school on campus. One argument stated that children need to be back in school. Since children need to be education, if younger children are being taught at home, a parent needs to be there to help support them. If a parent has to be home with their children in order to learn, one parent will need to quit their job. However, not all households have 2 parents and can live off one income, therefore children need to be back in school.
The issue is whether or not children should be in person or online for the upcoming school year. The conclusion is that children need in person schooling. The first premise is that children need supervised and assisted with their schooling. The second premise is that if children need to be supervised and assisted, it will be a parents responsibility to now do so during the day, which will cause one parent to have to be home. The third premise is that because some households cannot survive without a parent working, then the children need to be back in school. This is an example of a deductive argument.
My next example is that around between one to two years, children start to develop identifiable language skills. My son is one and a half, a toddler, therefore it is highly probable that he will soon start speaking strings of words.

The conclusion is that my son will soon start speaking. The first premise is that children learn to speak and string words together between one and two years of age. The second premise is that my son is between one and two years of age. This is an example of an inductive argument.
Facione and Gittens defines inductive reasoning as “a large, important and quite diverse group of inferences justify the confident belief that their conclusion is very probably true given that their premises are all true. In my example, the reasons are that my son is a toddler and that toddlers start speaking around one or two. There is a high probability, although not exact certainty that he will soon start speaking in strings of words, given that both of my premises are true.

Lynne, thank you for your post for this week and providing your arguments from the New York Times.
In one of the premises I think you meant to write, “… Children need supervision and assistance. . .” not supervised and assisted, yes? Please be mindful of grammar.
Nice example of an inductive argument. The reason it’s inductive is that is probably true but not necessarily.
1. “Fred, the Australian, stole my wallet. Thus, all Australians are thieves.” 2. “Satanist Quarterly reports that 87% of Americans are atheists. Therefore, there is no god.” 3. “Immigration to California from Mexico increased. Soon after, the welfare rolls increased.
Therefore, the increased immigration caused the increase in welfare rolls.” 4. “Protesting against racial injustice only causes more of it to occur.”

Hello Professor and class,
Inductive Argument
The rise of COVID-19 in the United States tracks almost precisely the decline of Donald Trump’s approval numbers and the political lesson from this is clear. The more damage the Wuhan coronavirus does to America, the harder it is for the President to get reelected (Carlson, 2020).
The issue is whether President Trump will be reelected is caused by the outbreak of COVID-19. The conclusion is that it is harder for the President to get elected if COVID-19 continue to rise. The first premise is the decline of Donald Trump’s approval numbers. The second premise is that the more damage the Wuhan coronavirus does to America, the harder it is for the President to get reelected. This is inductive.
Deductive Argument
And although the Labor Department’s weekly jobless claims report showed the number of Americans filing for unemployment benefits rose for the first time in nearly four months, continuing claims — or the people receiving benefits after an initial week of aid — shrank by more than 1 million, suggesting employers are recalling laid-off workers (Henny, 2020).
The issue is whether the number of unemployment benefits are decreasing. The implied conclusion is that employers are recalling laid-off workers. The first premise is that the number of Americans filing for unemployment benefits shrank by more than 1 million. The second premise is that employers are recalling laid-off workers. This is a deductive argument.

Jonathan has to travel to New York from Chicago. He is a nervous traveler, so he compares statistics over the past 10 years on accidents involving buses, trains, automobiles, and planes on routes between the two cities. Jonathan determines that a bus is safer in terms of fewer lives lost than any of the other forms of travel. As he is about to purchase his ticket, however, he sees a newspaper story about a bus accident in which six people died. Jonathan decides not to buy the bus ticket and fly instead.

Good evening Professor Sheffield and class,
I chose to use two examples from our readings. The first example I chose is definitely inductive as it does not have true facts to back up the conclusion that was stated. There are many possibilities that could have come in to play with the outcome of the example. The example suggests because he is dressed as a hunter that the only conclusion is that it had to be due to a hunting accident.
A man is found dead of a gunshot wound to the stomach, his body in a seated position at the base of a tree in a forest. It is deer hunting season.
My second example is deductive reasoning. The example can only have three true outcomes. Either the brother and sister have at least one same parent or both same parents. It states a fact that can be backed up as the two people involved are siblings.

Hello Brian, thank you for your post for this week and providing the deductive and inductive arguments. Good examples and your answers are correct.
Some arguments offer one or more examples and support overgeneralization. Consider this: women in earlier times were married very young. Julia in Shakespeare’s Romeo and Juliet was not even 14 years old. In the middle ages, 13 was the normal age of marriage for Jewish woman. And doing Roman times, many Roman women were married at age 13 or younger.
This argument generalizes from three examples – Juliet, Jewish women in the Middle Ages, and Roman women during the Roman empire – two “many” or most women in earlier times.
You will find it very helpful to write short arguments in a way with the premises and the conclusion in order to see exactly how they work.
When do premises like these adequately support a generalization?

Hello Class,
Deductive reasoning requires to start with a few general ideas called premises and apply them to a specific situation. Inductive reasoning uses a set of specific observations to reach a conclusion.
Example 1:
A coffee shop owner observes that a few customers are waiting to enter when the store opens each day and decides to open an hour earlier on weekdays.
This is an example of deductive reasoning, the first premise is that customers are waiting outside to enter. The second is that if the shop opens an hour early the customers will not have to wait. Deductive reasoning is “Using specific observations to reach a general conclusion” (Doyle, 2020).
Example 2:
After reviewing their numbers, development executives at a college believe that professionals working in the financial sector are the best donors. They direct their two most effective staff members to target alumni working in finance when it comes time to plan their next fundraising strategy” (Doyle, 2020)
This is an example of inductive reasoning, it uses a general idea to reach a specific conclusion.

Hello Diane, thank you for your post this week. Good examples of arguments.
Reconstruct the following argument. Identify those that are instances of a correct inductive form and those that are fallacious. If the background knowledge required to evaluate the argument is missing, discuss what would be needed.
The following argument by a fictional character supports the use of folk medicines:
I know they have been well reported of and many wise persons have tried remedies providentially discovered by those who are not regular physicians and have found a blessing in the use of them. I may mention the imminent Mr. Wesley [the founder of Methodism], who, thought I hold not together with his Arminian doctrine, nor with the usages of his institution, was nevertheless a man of God.

Deductive Reasoning
“If Richard graduated with honors, then Richard maintained a GPA of 3.2 or higher. It is not the case that Richard maintained a GPA of 3.2 or higher. Therefore, Richard did not graduate with honors.” (Facione, 2016). This argument does pass the test of validity and strength because it follows the “denying the
7/30/20, 8:14 PM Page 40 of 48
” Reply &
consequent” argument template in the text. This example deduces that since Richard did not maintain a 3.2 GPA, he did not graduate with honors.
Inductive Reasoning
“A man is found dead of a gunshot wound to the stomach, his body in a seated position at the base of a tree in a forest. It is deer hunting season. Except for not wearing an orange safety vest, he is dressed like a hunter. His hunting rifle, never been fired, lies on the ground at his side. The evidence strongly suggests that his death resulted from a hunting accident.” (Facione, 2016). Inductive reasoning is an umbrella term for making inferences to come to a conclusion. This is a very good example of inductive reasoning because the reporter inferred the cause of death based on the way the victim was dressed, and where he was found. I do not think this example passes the test of validity because the argument is based on an assumption. The validity of the argument can be threatened with an investigation of the death.

Hello Class,
The two major types of reasoning are inductive and deductive. These refer to the process by which someone creates a conclusion and how much they believe their own conclusion. Some examples are as follows.
Inductive:
The past five Marvel movies have been really good, therefore the next movie will also good. Even though this syllogism overlaps, it does not mean it’s true. This is not enough correlation between one movie and another to compare it as if it’s the same thing.
Deductive:
All art is an imitation of nature. Meaning that music is art. Therefore, music is an imitation of nature. – this example represents a correct correlation as the two concepts share the same properties.

What kind of argument is Wicker using against North? Is Wicker justified?
After so much lying, even for purposes North considers patriotic, his protestation that he now only wants to tell the truth aren’t worth much. Why should he be considered believable, even under oath, when he testified under oath that he had so often considered other values more important than truth?

Prof. Sheffield and class,
Inductive:
This is an example of inductive, and the first issue is whether students saved more money graduating in 3 years. the conclusion is that NYU believes students do. The first premise is the 20% of students who graduated in 3 years. The second premise is more students are graduating earlier than before. You can argue about the claim of 1 year less of college saves student’s money. You can argue that with more time in class with extra classes, the less time for other activities such as work. Having less income makes college less affordable in 3 years.
Deductive:
EX. John wanted to eat a fruit. He opened the fridge and saw celery, carrot, and a granny smith. He knows carrots and celery are not fruits. He knows granny smith is an apple. He will eat the Granny Smith because all apples are fruit.
The issue is do we consider all granny smiths a fruit. The implied conclusion is that granny smith is an apple and all apples are fruit. Both of the facts are true and logical. Therefore he is able to eat the granny smith because it is a fruit.

Scott, thank you for your post for this week. Great examples, specifically the one about the UY students and it is indeed inductive. Your second example is also deductive as indicated.
Test Your Understanding with Valid and Invalid
For each of the following deductive arguments, determine whether it is valid or invalid.
1. Some dogs are mammals. Some dogs are poodles. Thus some mammals are poodles. 2. Either the former U.S. president George W. Bush was not a professional baseball player or he
was not a famous rock singer. But he was a famous rock singer. Thus George W. Bush was not a professional baseball player.
3. The word ‘wet’ has three letters in it. Thus the word ‘wet’ has an odd number of letters in it.

Hello Everyone,
Deductive: With things changing daily due to the corona virus and the increase rate of cases in Chicago, Mayor Lori Lightfoot has put restrictions regarding travel outside of Chicago. She made it it mandatory to quarantine after travel to 22 states that are listed as risky. If one does not quarantine after travel to those states, they will be fined (Byrne, 2020).
The claim in this article states people who travel outside of Chicago to 22 states listed as risky will have to self-quarantine for 2 weeks to reduce COVID cases in Chicago. Anyone who fails to do so will have to pay a fine. The first premise is that anyone traveling from Chicago to one of the 22 states has to quarantine. The second premise is if one does not self-quarantine, they will be fined. In conclusion, to lower COVID-19 rates in Chicago, the Mayor requires people who travel to these 22 states to self-quarantine.

Inductive: I came across this article a while back and always found it interesting. During spring season in Chicago, around 5 million birds migrate through Chicago to other states and countries. Due to migrating, several birds die due to natural reasons and some die due to running into glass buildings. Since Chicago’s skyline is mostly made of glass, it causes a lot of birds to get hurt from running into glass windows during this time of the year (Briscoe & Dampier, 2019).
The main issue in this news article is that birds are dying in Chicago more often in spring season. The first premise is that birds die to natural causes and running into glass windows/buildings. The second premise is that the Chicago skyline has several glass buildings. I believe this would be inductive. It could be correct given the strength of the arrangement, but if more facts and other information was given on this, this can change its arguments strength.

Hello Navjeet, thank you for your post for this week and providing examples of both deductive and inductive arguments from news feeds.
Arguments based on samples share a common form called inductive generalization. Other names for the sample form a simple deduction, induction by enumeration, and statistical generalization. Inductive generalizations arguments from the particular to the general. They have a characteristic that has been inaccurately attributed to all inductive reasoning. The premises of inductive generalizations are about particular cases (the cases that make up sample), though their conclusions are generalizations about a population. Moreover, inductive generalization is such a common form of inductive argument that those who define induction is arguing from the particular to the general might be excused from focusing on this one important type.
Decide whether the following argument is an acceptable inductive generalization or a fallacy. Identify the premises and the conclusion of the argument. In the case of a fallacy, explain

what is wrong. Discuss what sort of additional background information, if any, is needed.
A nationwide poll the day after a presidential election called registered voters on their landline phones to ask whether they had voted, and 60 percent answered yes. Thus, between 59 percent and 61 percent of registered voters actually voted.
All the members of my fraternity have tickets to our school’s football game this weekend. Therefore the game is sure to be sold out.

Hello Professor and class,
Inductive Reasoning
“By threatening unemployment benefits, Republicans risk sending the economy over a cliff” (Editorial Board, 2020). The editorial board opens their argument with this statement as the title, then continues to mention the $600 weekly unemployment Covid-19 supplement that was enacted by the Government months ago and its expiration date come the end of July. The board continues on to state the current standstill between the Democrat and Republican party within the Senate in regard to passing a new supplement at a lower cost. The board then provides their opinion on wage replacement that falls in between that of the two parties. The only commentary towards the economy is that the failure of the GOP to replace the supplement by the end of July would start the economic downfall that the politicians are desperate to avoid.
Logically, this inductive argument does make sense. If the GOP does not enact a new or strong-enough supplement, it will negatively impact the economy, especially with the growing number of Covid-19 cases. The GOP was aware that the $600 supplement was actually more than what many workers made on a weekly basis however, dramatically decreasing the supplement is not wise because there are still so few jobs available and completely reopening the economy poses a huge health risk. The strongest part of this argument was the statement that “The Congressional Budget Office estimates that 5 of every 6 unemployed Americans will be better off receiving benefits than working by the end of 2020, if the $600 supplement remains in place” (Editorial Board, 2020). The original claim by the board is valid because the wrong supplement or no supplement will send the economy over a cliff.

“We have limited time and funds to get students and teachers back to school safely, but we can — and must — do it” (Allen, J.G, Corsi, R., 2020). Schools have been ordered to reopen in the midst of Covid-19. Allen and Corsi have proposed a method to safely do so, which includes staying home when sick, wearing masks, air purifiers in classrooms, refreshing ventilation, and temporary classrooms. Their method is neither logical nor strong because they mention several times that not all schools have the capability to do this. Some people can be asymptomatic, and others have to other choice but to go to school due to family dynamics such as poverty. There is a low supply of air purifies in the capacity needed for schools, companies would collectively need to produce another 1.5 million and that does not include replacements. Refreshing ventilation means new or improved ventilation systems and that is not something that all schools have the money for, especially in such a limited time frame. The temporary classrooms mentioned were tents, which are not feasible because of weather changes. What also weakened this argument was that the last two paragraphs came off as satire. The article overall seemed to be very sarcastic, as if the authors intentionally created such a weak argument to show that reopening schools is a terrible idea. Even with fallacies, the article did not take into consideration changing variables such as the students themselves. Students can be infected outside of schools and then spread Covid-19 unknowingly. Especially since schools, especially lower-income schools, tend to be overpopulated and children are generally unhygienic. This deductive argument was weak overall.
