Q

Failing to notice what can lead to falling to equivication?

A

To fall prey to an argument that employs equivocation, by contrast, is to fail to notice an ambiguity, or in some cases an instance of vagueness, thereby accepting the conclusion of an argument

Q

Is the red herring technique a substantive fallacy? Why?

A

Note that although red herring arguments can easily be represented as valid, red herring is not a substantive fallacy, what is and what is not relevant to a conclusion will depend on the conclusion’s particular subject matter.

Q

What is meant by the slippery slope technique

A

when an arguer wrongly assumes that to permit or forbid a course of action will inevitably lead to the occurrence of further related and undesirable events, without providing good reasons to suppose that the further events will indeed inevitably follow; and thus to allow the first is to tread on a slippery slope down which we will slide to the other events.

Q

What is meant by the straw target technique?

A

This is the technique used when an arguer ignores their opponent’s real position on an issue and sets up a weaker version of that position by misrepresentation, exaggeration, distortion or simplification.

Q

What is meant by begging the question?

A

An argument commits the fallacy of begging the question – sometimes called ‘circular reasoning’ – when the truth of its conclusion is assumed by one or more of its premises, and the truth of the premise(s) depends for its justification on the truth of the conclusion.

Q

Explain the difference between relative and absolute risk in terms of a medication trial.

A

Relative risk is a measure of the difference in risk between someone taking the medication that’s being trialled and someone who’s not taking it.
The absolute risk is the risk of someone in the general population.
So if trials of Roccastatin are reported to reduce the risk of heart attack by 54 per cent, we should understand this as a 54 per cent reduction in the absolute risk. Suppose that risk is 0.5 per cent – 1 in 200 – then taking the new medication would reduce that risk to 0.27 per cent – 1 in approximately 370

18
Q

What are fallacies?

A

arguments that make use of a mistake in reasoning

19
Q

What is the differences between formal and informal fallacies?

A

Formal fallacies are fallacies in which there is an inappropriate logical connection. Informal (substantive) fallacies are fallacies which involve reliance on a generalisation, unjustified assumptions or inferences. This often includes the reliance on an implicit assumption.

20
Q

Name four formal fallacies

A

Affirming the consequent, denying the antecedent, deriving ought from is, base rate

21
Q

What is meant by deriving ought from is?

A

A prescriptive conclusion cannot be validly derived from descriptive premises. This fallacy does exactly that.

22
Q

What is the ad hominem fallacy?

A

This is responding to a claim by making an attack upon the person or by rejecting a claim because of dislike for the person making the claim.

23
Q

What is meant by ad hominem circumstantial

A

This is believing that an argument is discounted because the person making the argument would allegedly benefit from people believing the argument

24
Q

What is the tu quoque fallacy

A

This is making unwarranted conclusions between a person’s alleged lack of credibility and the strength of their argument. It assumes that whenever a person’s behaviour is inconsistent with their advice, the advice is either false or should not be taken seriously.

25
Q

What is meant by the perfectionist fallacy?

A

This is rejecting an argument because it will not completely solve a problem. It contains the hidden premise that if a solution does not completely solve a problem, it should not be used.

26
Q

What is meant by conflation of morality with legality?

A

This is assuming that anything that is legal must be moral or that anything that is illegal must be immoral. “There is no law against it, so it’s acceptable”.

27
Q

What is meant by a weak analogy?

A

This is assuming that if one entity is similar to another entity in one aspect, it is similar in all the aspects.

28
Q

What is meant by Post hoc ergo propter hoc?

A

This is inferring that an event caused another event merely on the basis that one event occurred after the other. “After that, this, therefore this because of that”.

29
Q

Name two other causal fallacies

A

Mistaken correlation for cause and inversion of cause and effect

30
Q

Name two epistemic fallacies

A

Appeal to ignorance: This is assuming that if something is not proven, that it must be false or that if something has not been disproven, it must be correct.
Epistemic fallacy: This is assuming that if someone believes A, someone must also believe B, based on the grounds that A and B are about the same thing or person.

31
Q

How is the margin of error involved in faulty argument techniques?

A

Misinterpreting the margin of error (usually a confidence interval)
