Q

Simple Propositions

Have no internal structure, meaning whether they are True or False does not depend on whether a part of them is True or False on their own.

Q

Complex Propositions

A

Have internal logical structure, composed of simple propositions. Whether complex propositions are True or False depends on whether their parts are True or False, and how those parts are connected

Q

Premise

A

A premise is a proposition lending support to the conclusion. Premises are supposed to be statements that, if you accept they are true, give you reason to believe that the conclusion is also true.

Q

Logical Relationship

A

If you think the premises are True, and the argument is well formed, you should also think that the Conclusion is True

Q

Deductive Arguments

If the premises are True and the argumentive structure is good, then the conclusion must be True.

Q

Inductive Arguments

A

If the argumentative structure is great, the Truth of the premises only makes the conclusion probably true at best.
(Includes arguments from analogy, qualified authority, casual inferences, scientific hypothetical reasoning, extrapolations from samples, and so on.)

Q

Inductive Argumentative

A

Q

Valid Argument

A

A Valid Argument structure is where the truth of the premises would guarantee the truth of the conclusion. “if” the premises are true, the conclusion follows necessarily.
*It is impossible for the premises of a valid argument to be true and the conclusion False.

Q

Soundness

A

Soundness is about both structure and truth.
Must have good structure and true premises to make a sound argument.
*A Deductive argument is sound if it has a valid structure and all its premises are true.

A

Heuristic means a rule of thumb, a ready strategy, or a shortcut.
- There is no promise that it is going to work all of the time. It just needs to work well enough to get you through life.
- Rather than spend all the time and energy it takes to make the best decision, we can use a heuristic to make a pretty good decision
- Jumping to Conclusions

30
Q

Bounded Rationality

A

Dominate behavioral economics is called “bounded rationality”.
- We make the best decisions we can, with what we have

31
Q

Availability Heuristic

A

A mental shortcut relying on psychology salient or easily imagined examples rather than actual odds or factual information

32
Q

Algorithm Bubble

A

The curated and personalized version of online reality that a website shows you when you log on

33
Q

Self Selection

A

Self selection bias happens when the sample we generalize from is not representative of the total population in some important respect

34
Q

Representativeness Heuristic

A

Makes people judge a situation by means of situations in memories that bear similarities to it, even if those similarities are not really relevant.
- Look for carefully conducted scientific studies or larger sets of data when available.

35
Q

Anchoring Bias

A

Causes people to put too much weight on the first information received when making further decisions.
- Get larger sets of more objective data and don’t rely on personal anchors

36
Q

Availability Bias

A

Causes people to make judgements based on whichever examples come most readily to mind

37
Q

System 1 Thinking

A

Quick, Automatic, and Emotional

38
Q

System 2 Thinking

A

Deliberate, Effortful, and Calculating

39
Q

Circular Reasoning Fallacy

A

When one’s conclusion is supported by a premise that is identical to the conclusion.

40
Q

Ad Hominem Fallacy

A

Ad Hominem Fallacy occurs when someone attacks the arguer instead of the argument itself.
“Against the Person”

41
Q

Genetic Fallacy

A

Sometimes lumped in with Ad Hominem Fallacies. Genetic Fallacy occurs when an arguer critiques the origin of a claim/argument rather than the claim/argument itself.
- Role beliefs play
- The origin of an idea has nothing inherently to do w/ its truth or plausibility

42
Q

Straw Figure/Straw Man Fallacy

A

Happens when someone (willfully/mistakenly) misinterprets someone else’s argument or position. Irrelevant!

43
Q

Red Herring

A

Not staying on topic. Intentionally/Unintentionally change the subject to avoid the real issue at hand

A

Equivocation can only be identified by understanding the meanings of the words involved. (Two different meanings)

45

A

Is committed when one event is said to lead to some other (disastrous) event via a chain of intermediary events

47
Q

Slippery Slope Fallacy

Happens when someone already knows which conclusion they’d like to prove and then selects evidence which supports that conclusion

49
Q

Post Hoc

A

“After this, therefore because of this’

X occured before Y, Therefore X caused Y OR
X happened after Y, Therefore Y caused X
