Fallacies

Question 1

Ad Hominem

Answer 1

A claim is rejected based on irrelevant facts about the author of the claim.

Person A makes claim X.
Person B makes an attack on person A.
Therefore A’s claim is false.

Bill: “I believe that abortion is morally wrong.”
Dave: “Of course you would say that, you’re a priest.”
Bill: “What about the arguments I gave to support my position?”
Dave: “Those don’t count. Like I said, you’re a priest, so you have to say that abortion is wrong. Further, you are just a lackey to the Pope, so I can’t believe what you say.”

Question 2

Ad Hominem Tu Quoque

Answer 2

Also Known as: “You Too Fallacy”
This fallacy is committed when it is concluded that a person’s claim is false because 1) it is inconsistent with something else a person has said or 2) what a person says is inconsistent with her actions. This type of “argument” has the following form:

Person A makes claim X.
Person B asserts that A’s actions or past claims are inconsistent with the truth of claim X.
Therefore X is false.

Peter: “Based on the arguments I have presented, it is evident that it is morally wrong to use animals for food or clothing.”
Bill: “But you are wearing a leather jacket and you have a roast beef sandwich in your hand! How can you say that using animals for food and clothing is wrong!”

Question 3

Appeal to Authority

Answer 3

An Appeal to Authority is a fallacy with the following form:

Person A is (claimed to be) an authority on subject S.
Person A makes claim C about subject S.
Therefore, C is true.

This fallacy is committed when the person in question is not a legitimate authority on the subject. More formally, if person A is not qualified to make reliable claims in subject S, then the argument will be fallacious.

I’m not a doctor, but I play one on the hit series “Bimbos and Studmuffins in the OR.” You can take it from me that when you need a fast acting, effective and safe pain killer there is nothing better than MorphiDope 2000. That is my considered medical opinion.

Question 4

Appeal to Belief

Answer 4

Most people believe that a claim, X, is true.
Therefore X is true.

This line of “reasoning” is fallacious because the fact that many people believe a claim does not, in general, serve as evidence that the claim is true.

God must exist. After all, I just saw a poll that says 85% of all Americans believe in God.

Question 5

Appeal to Common Practice

Answer 5

X is a common action.
Therefore X is correct/moral/justified/reasonable, etc.

The basic idea behind the fallacy is that the fact that most people do X is used as “evidence” to support the action or practice. It is a fallacy because the mere fact that most people do something does not make it correct, moral, justified, or reasonable.

“Yeah, I know some people say that cheating on tests is wrong. But we all know that everyone does it, so it’s okay.”

Question 6

Appeal to Consequences of a Belief

Answer 6

X is true/false because if people did not accept X as being true/false then there would be negative consequences.
X is true because accepting that X is true has positive consequences.
I wish that X were true/false, therefore X is true. This is known as Wishful Thinking.

“I acknowledge that I have no argument for the existence of God. However, I have a great desire for God to exist and for there to be an afterlife. Therefore I accept that God exists.”

Question 7

Appeal to Emotion

Answer 7

An Appeal to Emotion is a fallacy with the following structure:

Favorable emotions are associated with X.
Therefore, X is true.

This fallacy is committed when someone manipulates peoples’ emotions in order to get them to accept a claim as being true. More formally, this sort of “reasoning” involves the substitution of various means of producing strong emotions in place of evidence for a claim. If the favorable emotions associated with X influence the person to accept X as true because they “feel good about X,” then he has fallen prey to the fallacy.

The new UltraSkinny diet will make you feel great. No longer be troubled by your weight. Enjoy the admiring stares of the opposite sex. Revel in your new freedom from fat. You will know true happiness if you try our diet!

Question 8

Appeal to Fear

Answer 8

he Appeal to Fear is a fallacy with the following pattern:

Y is presented (a claim that is intended to produce fear).
Therefore claim X is true (a claim that is generally, but need not be, related to Y in some manner).

This line of “reasoning” is fallacious because creating fear in people does not constitute evidence for a claim.

You must believe that God exists. After all, if you do not accept the existence of God, then you will face the horrors of hell.

Question 9

Appeal to Flattery

Answer 9

An Appeal to Flattery is a fallacy of the following form:

Person A is flattered by person B.
Person B makes claim X.
Therefore X is true.

The basic idea behind this fallacy is that flattery is presented in the place of evidence for accepting a claim. this sort of “reasoning” is fallacious because flattery is not, in fact, evidence for a claim. This is especially clear in a case like this: “My Bill, that is a really nice tie. By the way, it is quite clear that one plus one is equal to forty three.”

“Might I say that this is the best philosophy class I’ve ever taken. By the way, about those two points I need to get an A…”

Question 10

Appeal to Novelty

Answer 10

Appeal to Novelty is a fallacy that occurs when it is assumed that something is better or correct simply because it is new. This sort of “reasoning” has the following form:

X is new.
Therefore X is correct or better.

This sort of “reasoning” is fallacious because the novelty or newness of something does not automatically make it correct or better than something older. This is made quite obvious by the following example: Joe has proposed that 1+1 should now be equal to 3. When asked why people should accept this, he says that he just came up with the idea. Since it is newer than the idea that 1+1=2, it must be better.

Question 11

Appeal to Pity

Answer 11

An Appeal to Pity is a fallacy in which a person substitutes a claim intended to create pity for evidence in an argument. The form of the “argument” is as follows:

P is presented, with the intent to create pity.
Therefore claim C is true.

This line of “reasoning” is fallacious because pity does not serve as evidence for a claim. This is extremely clear in the following case: “You must accept that 1+1=46, after all I’m dying…” While you may pity me because I am dying, it would hardly make my claim true.

Question 12

Appeal to Popularity

Answer 12

The Appeal to Popularity has the following form:

Most people approve of X (have favorable emotions towards X).
Therefore X is true.

The basic idea is that a claim is accepted as being true simply because most people are favorably inclined towards the claim. More formally, the fact that most people have favorable emotions associated with the claim is substituted in place of actual evidence for the claim. A person falls prey to this fallacy if he accepts a claim as being true simply because most other people approve of the claim.

“I read the other day that most people really like the new gun control laws. I was sort of suspicious of them, but I guess if most people like them, then they must be okay.”

Question 13

Appeal to Ridicule

Answer 13

The Appeal to Ridicule is a fallacy in which ridicule or mockery is substituted for evidence in an “argument.” This line of “reasoning” has the following form:

X, which is some form of ridicule is presented (typically directed at the claim).
Therefore claim C is false.

This sort of “reasoning” is fallacious because mocking a claim does not show that it is false. This is especially clear in the following example: “1+1=2! That’s the most ridiculous thing I have ever heard!”

Question 14

Appeal to Spite

Answer 14

The Appeal to Spite Fallacy is a fallacy in which spite is substituted for evidence when an “argument” is made against a claim. This line of “reasoning” has the following form:

Claim X is presented with the intent of generating spite.
Therefore claim C is false (or true)

This sort of “reasoning” is fallacious because a feeling of spite does not count as evidence for or against a claim. This is quite clear in the following case: “Bill claims that the earth revolves around the sun. But remember that dirty trick he pulled on you last week. Now, doesn’t my claim that the sun revolves around the earth make sense to you?”

Question 15

Appeal to Tradition

Answer 15

Appeal to Tradition is a fallacy that occurs when it is assumed that something is better or correct simply because it is older, traditional, or “always has been done.” This sort of “reasoning” has the following form:

X is old or traditional
Therefore X is correct or better.

This sort of “reasoning” is fallacious because the age of something does not automatically make it correct or better than something newer. This is made quite obvious by the following example: The theory that witches and demons cause disease is far older than the theory that microrganisms cause diseases. Therefore, the theory about witches and demons must be true.

Question 16

Bandwagon

Answer 16

AKA Peer Pressure
The Bandwagon is a fallacy in which a threat of rejection by one’s peers (or peer pressure) is substituted for evidence in an “argument.” This line of “reasoning” has the following form:

Person P is pressured by his/her peers or threatened with rejection.
Therefore person P’s claim X is false.

This line of “reasoning” is fallacious because peer pressure and threat of rejection do not constitute evidence for rejecting a claim. This is expecially clear in the following example:

Joe: “Bill, I know you think that 1+1=2. But we don’t accept that sort of thing in our group. “
Bill: “I was just joking. Of course I don’t believe that.”

Question 17

Begging the Question

Answer 17

AKA Circular Reasoning
Begging the Question is a fallacy in which the premises include the claim that the conclusion is true or (directly or indirectly) assume that the conclusion is true. This sort of “reasoning” typically has the following form.

Premises in which the truth of the conclusion is claimed or the truth of the conclusion is assumed (either directly or indirectly).
Claim C (the conclusion) is true.

This sort of “reasoning” is fallacious because simply assuming that the conclusion is true (directly or indirectly) in the premises does not constitute evidence for that conclusion. Obviously, simply assuming a claim is true does not serve as evidence for that claim. This is especially clear in particularly blatant cases: “X is true. The evidence for this claim is that X is true.”

Bill: "God must exist." 
Jill: "How do you know." 
Bill: "Because the Bible says so." 
Jill: "Why should I believe the Bible?" 
Bill: "Because the Bible was written by God."

Question 18

Biased Sample

Answer 18

This fallacy is committed when a person draws a conclusion about a population based on a sample that is biased or prejudiced in some manner. It has the following form:

Sample S, which is biased, is taken from population P.
Conclusion C is drawn about Population P based on S.

The person committing the fallacy is misusing the following type of reasoning, which is known variously as Inductive Generalization, Generalization, and Statistical Generalization:

X% of all observed A’s are B’’s.
Therefore X% of all A’s are Bs.

The fallacy is committed when the sample of A’s is likely to be biased in some manner. A sample is biased or loaded when the method used to take the sample is likely to result in a sample that does not adequately represent the population from which it is drawn.

Large scale polls were taken in Florida, California, and Maine and it was found that an average of 55% of those polled spent at least fourteen days a year near the ocean. So, it can be safely concluded that 55% of all Americans spend at least fourteen days near the ocean each year.

Question 19

Burden of Proof

Answer 19

Burden of Proof is a fallacy in which the burden of proof is placed on the wrong side. Another version occurs when a lack of evidence for side A is taken to be evidence for side B in cases in which the burden of proof actually rests on side B. A common name for this is an Appeal to Ignorance. This sort of reasoning typically has the following form:

Claim X is presented by side A and the burden of proof actually rests on side B.
Side B claims that X is false because there is no proof for X.

In many situations, one side has the burden of proof resting on it. This side is obligated to provide evidence for its position. The claim of the other side, the one that does not bear the burden of proof, is assumed to be true unless proven otherwise. The difficulty in such cases is determining which side, if any, the burden of proof rests on. In many cases, settling this issue can be a matter of significant debate. In some cases the burden of proof is set by the situation. For example, in American law a person is assumed to be innocent until proven guilty (hence the burden of proof is on the prosecution). As another example, in debate the burden of proof is placed on the affirmative team. As a final example, in most cases the burden of proof rests on those who claim something exists (such as Bigfoot, psychic powers, universals, and sense data).

“You cannot prove that God does not exist, so He does.”

Question 20

Circumstantial Ad Hominem

Answer 20

A Circumstantial ad Hominem is a fallacy in which one attempts to attack a claim by asserting that the person making the claim is making it simply out of self interest. In some cases, this fallacy involves substituting an attack on a person’s circumstances (such as the person’s religion, political affiliation, ethnic background, etc.). The fallacy has the following forms:

Person A makes claim X.
Person B asserts that A makes claim X because it is in A’s interest to claim X.
Therefore claim X is false.

Person A makes claim X.
Person B makes an attack on A’s circumstances.
Therefore X is false.

A Circumstantial ad Hominem is a fallacy because a person’s interests and circumstances have no bearing on the truth or falsity of the claim being made. While a person’s interests will provide them with motives to support certain claims, the claims stand or fall on their own. It is also the case that a person’s circumstances (religion, political affiliation, etc.) do not affect the truth or falsity of the claim. This is made quite clear by the following example: “Bill claims that 1+1=2. But he is a Republican, so his claim is false.”

Question 21

Composition

Answer 21

The fallacy of Composition is committed when a conclusion is drawn about a whole based on the features of its constituents when, in fact, no justification provided for the inference. There are actually two types of this fallacy, both of which are known by the same name (because of the high degree of similarity).

The first type of fallacy of Composition arises when a person reasons from the characteristics of individual members of a class or group to a conclusion regarding the characteristics of the entire class or group (taken as a whole). More formally, the “reasoning” would look something like this.

Individual F things have characteristics A, B, C, etc.
Therefore, the (whole) class of F things has characteristics A, B, C, etc.
This line of reasoning is fallacious because the mere fact that individuals have certain characteristics does not, in itself, guarantee that the class (taken as a whole) has those characteristics.

It is important to note that drawing an inference about the characteristics of a class based on the characteristics of its individual members is not always fallacious. In some cases, sufficient justification can be provided to warrant the conclusion. For example, it is true that an individual rich person has more wealth than an individual poor person. In some nations (such as the US) it is true that the class of wealthy people has more wealth as a whole than does the class of poor people. In this case, the evidence used would warrant the inference and the fallacy of Composition would not be committed.

Atoms are colorless. Cats are made of atoms, so cats are colorless.

Question 22

Confusing Cause and Effect

Answer 22

Confusing Cause and Effect is a fallacy that has the following general form:

A and B regularly occur together.
Therefore A is the cause of B.
This fallacy requires that there is not, in fact, a common cause that actually causes both A and B.

This fallacy is committed when a person assumes that one event must cause another just because the events occur together. More formally, this fallacy involves drawing the conclusion that A is the cause of B simply because A and B are in regular conjunction (and there is not a common cause that is actually the cause of A and B). The mistake being made is that the causal conclusion is being drawn without adequate justification.

It is claimed by some people that severe illness is caused by depression and anger. After all, people who are severely ill are very often depressed and angry. Thus, it follows that the cause of severe illness actually is the depression and anger. So, a good and cheerful attitude is key to staying healthy.

Question 23

Division

Answer 23

The fallacy of Division is committed when a person infers that what is true of a whole must also be true of its constituents and justification for that inference is not provided.

There are two main variants of the general fallacy of Division:

The first type of fallacy of Division is committed when 1) a person reasons that what is true of the whole must also be true of the parts and 2) the person fails to justify that inference with the required degree of evidence. More formally, the “reasoning” follows this sort of pattern:

The whole, X, has properties A, B, C, etc.
Therefore the parts of X have properties A, B, C, etc.
That this line of reasoning is fallacious is made clear by the following case: 4 is an even number. 1 and 3 are parts of 4. Therefore 1 and 3 are even.

It should be noted that it is not always fallacious to draw a conclusion about the parts of a whole based on the properties of the whole. As long as adequate evidence is provided in the argument, the the reasoning can be acceptable. For example, the human body is made out of matter and it is reasonable to infer from this that the parts that make up the human body are also made out of matter. This is because there is no reason to believe that the body is made up of non-material parts that somehow form matter when they get together.

“The ball is blue, therefore the atoms that make it up are also blue.”

Question 24

False Dilemma

Answer 24

AKA Black & White Thinking
A False Dilemma is a fallacy in which a person uses the following pattern of “reasoning”:

Either claim X is true or claim Y is true (when X and Y could both be false).
Claim Y is false.
Therefore claim X is true.
This line of “reasoning” is fallacious because if both claims could be false, then it cannot be inferred that one is true because the other is false. That this is the case is made clear by the following example:

Either 1+1=4 or 1+1=12.
It is not the case that 1+1=4.
Therefore 1+1=12.

Question 25

Gambler's Fallacy

Answer 25

The Gambler's Fallacy is committed when a person assumes that a departure from what occurs on average or in the long term will be corrected in the short term. The form of the fallacy is as follows: X has happened. X departs from what is expected to occur on average or over the long term. Therefore, X will come to an end soon. There are two common ways this fallacy is committed. In both cases a person is assuming that some result must be "due" simply because what has previously happened departs from what would be expected on average or over the long term. The first involves events whose probabilities of occuring are independent of one another. For example, one toss of a fair (two sides, non-loaded) coin does not affect the next toss of the coin. So, each time the coin is tossed there is (ideally) a 50% chance of it landing heads and a 50% chance of it landing tails. Suppose that a person tosses a coin 6 times and gets a head each time. If he concludes that the next toss will be tails because tails "is due", then he will have committed the Gambler's Fallacy. This is because the results of previous tosses have no bearing on the outcome of the 7th toss. It has a 50% chance of being heads and a 50% chance of being tails, just like any other toss.

Question 26

Genetic Fallacy

Answer 26

A Genetic Fallacy is a line of "reasoning" in which a perceived defect in the origin of a claim or thing is taken to be evidence that discredits the claim or thing itself. It is also a line of reasoning in which the origin of a claim or thing is taken to be evidence for the claim or thing. This sort of "reasoning" has the following form: The origin of a claim or thing is presented. The claim is true(or false) or the thing is supported (or discredited). It is clear that sort of "reasoning" is fallacious. For example: "Bill claims that 1+1=2. However, my parents brought me up to believe that 1+1=254, so Bill must be wrong." "I was brought up to believe in God, and my parents told me God exists, so He must."

Question 27

Guilt By Association

Answer 27

Guilt by Association is a fallacy in which a person rejects a claim simply because it is pointed out that people she dislikes accept the claim. This sort of "reasoning" has the following form: It is pointed out that people person A does not like accept claim P. Therefore P is false It is clear that sort of "reasoning" is fallacious. For example the following is obviously a case of poor "reasoning": "You think that 1+1=2. But, Adolf Hitler, Charles Manson, Joseph Stalin, and Ted Bundy all believed that 1+1=2. So, you shouldn't believe it."

Question 28

Hasty Generalization

Answer 28

This fallacy is committed when a person draws a conclusion about a population based on a sample that is not large enough. It has the following form: Sample S, which is too small, is taken from population P. Conclusion C is drawn about Population P based on S. The person committing the fallacy is misusing the following type of reasoning, which is known variously as Inductive Generalization, Generalization, and Statistical Generalization: X% of all observed A's are B''s. Therefore X% of all A's are Bs. The fallacy is committed when not enough A's are observed to warrant the conclusion. If enough A's are observed then the reasoning is not fallacious.

Question 29

Ignoring a Common Cause

Answer 29

This fallacy has the following general structure: A and B are regularly connected (but no third, common cause is looked for). Therefore A is the cause of B. This fallacy is committed when it is concluded that one thing causes another simply because they are regularly associated. More formally, this fallacy is committed when it is concluded that A is the cause of B simply because A and B are regularly connected. Further, the causal conclusion is drawn without considering the possibility that a third factor might be the cause of both A and B. One day Bill wakes up with a fever. A few hours later he finds red spots on his skin. he concludes that the fever must have caused the red spots. His friend insists that the spots and the fever are caused by some microbe. Bill laughs at this and insists that if he spends the day in a tub of cold water his spots will go away.

Question 30

Middle Ground

Answer 30

This fallacy is committed when it is assumed that the middle position between two extremes must be correct simply because it is the middle position. this sort of "reasoning" has the following form: Position A and B are two extreme positions. C is a position that rests in the middle between A and B. Therefore C is the correct position. This line of "reasoning" is fallacious because it does not follow that a position is correct just because it lies in the middle of two extremes. This is shown by the following example. Suppose that a person is selling his computer. He wants to sell it for the current market value, which is $800 and someone offers him $1 for it. It would hardly follow that $400.50 is the proper price.

Question 31

Misleading Vividness

Answer 31

Misleading Vividness is a fallacy in which a very small number of particularly dramatic events are taken to outweigh a significant amount of statistical evidence. This sort of "reasoning" has the following form: Dramatic or vivid event X occurs (and is not in accord with the majority of the statistical evidence) . Therefore events of type X are likely to occur. This sort of "reasoning" is fallacious because the mere fact that an event is particularly vivid or dramatic does not make the event more likely to occur, especially in the face of significant statistical evidence. Joe and Drew are talking about flying. Joe: "When I was flying back to school, the pilot came on the intercom and told us that the plane was having engine trouble. I looked out the window and I saw smoke billowing out of the engine nearest me. We had to make an emergency landing and there were fire trucks everywhere. I had to spend the next six hours sitting in the airport waiting for a flight. I was lucky I didn't die! I'm never flying again." Drew: "So how are you going to get home over Christmas break?" Joe: "I'm going to drive. That will be a lot safer than flying." Drew: "I don't think so. You are much more likely to get injured or killed driving than flying." Joe: "I don't buy that! You should have seen the smoke pouring out of that engine! I'm never getting on one of those death traps again!"

Question 32

Personal Attack

Answer 32

A personal attack is committed when a person substitutes abusive remarks for evidence when attacking another person's claim or claims. This line of "reasoning" is fallacious because the attack is directed at the person making the claim and not the claim itself. The truth value of a claim is independent of the person making the claim. After all, no matter how repugnant an individual might be, he or she can still make true claims. Not all ad Hominems are fallacious. In some cases, an individual's characteristics can have a bearing on the question of the veracity of her claims. For example, if someone is shown to be a pathological liar, then what he says can be considered to be unreliable. However, such attacks are weak, since even pathological liars might speak the truth on occasion. In general, it is best to focus one's attention on the content of the claim and not on who made the claim. It is the content that determines the truth of the claim and not the characteristics of the person making the claim. In a school debate, Bill claims that the President's economic plan is unrealistic. His opponent, a professor, retorts by saying "the freshman has his facts wrong."

Question 33

Poisoning the Well

Answer 33

This sort of "reasoning" involves trying to discredit what a person might later claim by presenting unfavorable information (be it true or false) about the person. This "argument" has the following form: ``` Unfavorable information (be it true or false) about person A is presented. Therefore any claims person A makes will be false. ``` This sort of "reasoning" is obviously fallacious. The person making such an attack is hoping that the unfavorable information will bias listeners against the person in question and hence that they will reject any claims he might make. However, merely presenting unfavorable information about a person (even if it is true) hardly counts as evidence against the claims he/she might make. This is especially clear when Poisoning the Well is looked at as a form of ad Homimem in which the attack is made prior to the person even making the claim or claims. The following example clearly shows that this sort of "reasoning" is quite poor. Before Class: Bill: "Boy, that professor is a real jerk. I think he is some sort of eurocentric fascist." Jill: "Yeah." During Class: Prof. Jones: "...and so we see that there was never any 'Golden Age of Matriarchy' in 1895 in America." After Class: Bill: "See what I mean?" Jill: "Yeah. There must have been a Golden Age of Matriarchy, since that jerk said there wasn't."

Question 34

Post Hoc

Answer 34

A Post Hoc is a fallacy with the following form: A occurs before B. Therefore A is the cause of B. The Post Hoc fallacy derives its name from the Latin phrase "Post hoc, ergo propter hoc." This has been traditionally interpreted as "After this, therefore because of this." This fallacy is committed when it is concluded that one event causes another simply because the proposed cause occurred before the proposed effect. More formally, the fallacy involves concluding that A causes or caused B because A occurs before B and there is not sufficient evidence to actually warrant such a claim. Bill purchases a new PowerMac and it works fine for months. He then buys and installs a new piece of software. The next time he starts up his Mac, it freezes. Bill concludes that the software must be the cause of the freeze.

Question 35

Questionable Cause

Answer 35

This fallacy has the following general form: A and B are associated on a regular basis. Therefore A is the cause of B. The general idea behind this fallacy is that it is an error in reasoning to conclude that one thing causes another simply because the two are associated on a regular basis. More formally, this fallacy is committed when it is concluded that A is the cause of B simply because they are associated on a regular basis. The error being made is that a causal conclusion is being drawn from inadequate evidence. The Questionable Cause Fallacy is actually a general type of fallacy. Any causal fallacy that involves an error in a reasoning due to a failure to adequately investigate the suspected cause is a fallacy of this type. Thus, fallacies like Post Hoc and Confusing Cause and Effect are specific examples of the general Questionable Cause Fallacy. Joe gets a chain letter that threatens him with dire consequences if he breaks the chain. He laughs at it and throws it in the garbage. On his way to work he slips and breaks his leg. When he gets back from the hospital he sends out 200 copies of the chain letter, hoping to avoid further accidents.

Question 36

Red Herring

Answer 36

A Red Herring is a fallacy in which an irrelevant topic is presented in order to divert attention from the original issue. The basic idea is to "win" an argument by leading attention away from the argument and to another topic. This sort of "reasoning" has the following form: Topic A is under discussion. Topic B is introduced under the guise of being relevant to topic A (when topic B is actually not relevant to topic A). Topic A is abandoned. This sort of "reasoning" is fallacious because merely changing the topic of discussion hardly counts as an argument against a claim. "I think there is great merit in making the requirements stricter for the graduate students. I recommend that you support it, too. After all, we are in a budget crisis and we do not want our salaries affected."

Question 37

Relativist Fallacy

Answer 37

The Relativist Fallacy is committed when a person rejects a claim by asserting that the claim might be true for others but is not for him/her. This sort of "reasoning" has the following form: Claim X is presented. Person A asserts that X may be true for others but is not true for him/her. Therefore A is justified in rejecting X. In this context, relativism is the view that truth is relative to Z (a person, time, culture, place, etc.). This is not the view that claims will be true at different times or of different people, but the view that a claim could be true for one person and false for another at the same time. In many cases, when people say "that X is true for me" what they really mean is "I believe X" or "X is true about me." It is important to be quite clear about the distinction between being true about a person and being true for a person. A claim is true about a person if the claim is a statement that describes the person correctly. For example, "Bill has blue eyes" is true of Bill if Bill has blue eyes. To make a claim such as "X is true for Bill" is to say that the claim is true for Bill and that it need not be true for others. For example: "1+1=23 is true for Bill" would mean that, for Bill, 1+1 actually does equal 23, not that he merely believes that 1+1=23 (that would be "It is true of Bill that he believes 1+1=23"). Another example would be "The claim that the earth is flat is true for Bill" would mean that the earth really is flat for Bill (in other words, Bill would be in a different world than the rest of the human race). Since these situations (1+1 being 23 and the earth being flat for Bill) are extremely strange, it certainly seems that truth is not relative to individuals (although beliefs are). As long as truth is objective (that is, not relative to individuals), then the Relativist Fallacy is a fallacy. If there are cases in which truth is actually relative, then such reasoning need not be fallacious. Jill: "Look at this, Bill. I read that people who do not get enough exercise tend to be unhealthy." Bill: "That may be true for you, but it is not true for me."

Question 38

Slippery Slope

Answer 38

The Slippery Slope is a fallacy in which a person asserts that some event must inevitably follow from another without any argument for the inevitability of the event in question. In most cases, there are a series of steps or gradations between one event and the one in question and no reason is given as to why the intervening steps or gradations will simply be bypassed. This "argument" has the following form: Event X has occurred (or will or might occur). Therefore event Y will inevitably happen. This sort of "reasoning" is fallacious because there is no reason to believe that one event must inevitably follow from another without an argument for such a claim. This is especially clear in cases in which there is a significant number of steps or gradations between one event and another. "We have to stop the tuition increase! The next thing you know, they'll be charging $40,000 a semester!"

Question 39

Special Pleading

Answer 39

Special Pleading is a fallacy in which a person applies standards, principles, rules, etc. to others while taking herself (or those she has a special interest in) to be exempt, without providing adequate justification for the exemption. This sort of "reasoning" has the following form: Person A accepts standard(s) S and applies them to others in circumtance(s) C. Person A is in circumstance(s) C. Therefore A is exempt from S. The person committing Special Pleading is claiming that he is exempt from certain principles or standards yet he provides no good reason for his exemption. That this sort of reasoning is fallacious is shown by the following extreme example: Barbara accepts that all murderers should be punished for their crimes. Although she murdered Bill, Barbara claims she is an exception because she really would not like going to prison. Therefore, the standard of punishing murderers should not be applied to her. This is obviously a blatant case of special pleading. Since no one likes going to prison, this cannot justify the claim that Barbara alone should be exempt from punishment. Bill and Jill are married. Both Bill and Jill have put in a full day at the office. Their dog, Rover, has knocked over all the plants in one room and has strewn the dirt all over the carpet. When they return, Bill tells Jill that it is her job to clean up after the dog. When she protests, he says that he has put in a full day at the office and is too tired to clean up after the dog.

Question 40

Spotlight

Answer 40

The Spotlight fallacy is committed when a person uncritically assumes that all members or cases of a certain class or type are like those that receive the most attention or coverage in the media. This line of "reasoning" has the following form: Xs with quality Q receive a great deal of attention or coverage in the media. Therefore all Xs have quality Q. This line of reasoning is fallacious since the mere fact that someone or something attracts the most attention or coverage in the media does not mean that it automatically represents the whole population. For example, suppose a mass murderer from Old Town, Maine received a great deal of attention in the media. It would hardly follow that everyone from the town is a mass murderer. The Spotlight fallacy derives its name from the fact that receiving a great deal of attention or coverage is often referred to as being in the spotlight. It is similar to Hasty Generalization, Biased Sample and Misleading Vivideness because the error being made involves generalizing about a population based on an inadequate or flawed sample. Joe: "Man, I'd never want to go to New York. It is all concrete and pollution." Sam: "Not all of it." Joe: "Sure it is. Everytime I watch the news they are always showing concrete skyscrapers, and lots of pollution." Sam: "Sure, that is what the news shows, but a lot of New York is farmlands and forest. It is not all New York City, it just receives most of the attention."

Question 41

Straw Man

Answer 41

The Straw Man fallacy is committed when a person simply ignores a person's actual position and substitutes a distorted, exaggerated or misrepresented version of that position. This sort of "reasoning" has the following pattern: Person A has position X. Person B presents position Y (which is a distorted version of X). Person B attacks position Y. Therefore X is false/incorrect/flawed. This sort of "reasoning" is fallacious because attacking a distorted version of a position simply does not constitute an attack on the position itself. One might as well expect an attack on a poor drawing of a person to hurt the person. "Senator Jones says that we should not fund the attack submarine program. I disagree entirely. I can't understand why he wants to leave us defenseless like that."

Question 42

Two Wrongs Make a Right

Answer 42

Two Wrongs Make a Right is a fallacy in which a person "justifies" an action against a person by asserting that the person would do the same thing to him/her, when the action is not necessary to prevent B from doing X to A. This fallacy has the following pattern of "reasoning": It is claimed that person B would do X to person A. It is acceptable for person A to do X to person B (when A's doing X to B is not necessary to prevent B from doing X to A). This sort of "reasoning" is fallacious because an action that is wrong is wrong even if another person would also do it. It should be noted that it can be the case that it is not wrong for A to do X to B if X is done to prevent B from doing X to A or if X is done in justified retribution. For example, if Sally is running in the park and Biff tries to attack her, Sally would eb jsutified in attacking Biff to defend herself. As another example, if country A is planning to invade country B in order to enslave the people, then country B would be justified in launching a pre-emptive strike to prevent the invasion. Bill has borrowed Jane's expensive pen, but found he didn't return it. He tell's himself that it is okay to keep it, since she would have taken his. After leaving a store, Jill notices that she has underpaid by $10. She decides not to return the money to the store because if she had overpaid, they would not have returned the money.
