Q

Neuroeconomics

A
  • The study of how we make (value-based) decisions
    The aim of neuroeconomics is to figure out the rules that guide our reasoning. Are there situations in which we won’t be so logical or rule followers? When that’s the case, what happens to our decisions?

Q

Syllogisms

A

old form of deductive reasoning

Q

Structure of syllogisms

A
  • Major premise (general)

Q

Validity of syllogisms

A

Are the conclusion true given the premises’ logical form?
* Valid = logical rules NOT Truth = world knowledge / content
* A valid structure (All A are B : All B are C: Therefore, all A are C)

Q

All statements syllogisms

A

Premise describes a truth in which all A are B (not necessarily that B are A too)
E.g.
All men are mortal
Socrates is a man
Therefore, Socrates is a mortal
Note : “All men are mortal” does not mean “All mortal are men”

Q

Negative statements syllogisms

A

Premise says No A is a B
Also means no B is A
E.g.
All psychology professors have PhDs
No PhD holders are human
Therefore, psychology professors are not human

Q

Some statements syllogisms

A

Some A are B.
“At least one, possibly all”
E.g.
No provinces with coastlines are provinces that are landlocked
Some provinces are landlocked
Therefore, some provinces are not states with coastlines
Ambiguous : can lead to atmosphere effect

22
Q

Atmosphere effect

A

People rate a conclusion as valid when the qualifying word (e.g., ‘all,’, ‘some’) in the premise match those in the conclusion
- Go with the overall mood : that seems correct

23
Q

Mental model theory

A
  • People construct mental simulations of the world based on statements (e.g., syllogisms) to judge logic and validity : difficult to do with negative judgment
  • our knowledge guides our reasoning, we do not always follow logic
24
Q

Omission bias

A
  • Biased thought that ”withholding is not as bad as doing”
  • Inaction is harder to classify as wrong than action
  • People tend to react more to strongly to harmful actions than to harmful inactions
25
What is the more common answer to this question : Which is more immoral? 1. A person who accidentally sets fire to a building 2. A person who sees a fire in a building but does not bother to report it.
- People tend to have more trouble reasoning with negative information - People tend to say the fire starter creates a worse outcome, but actually in both scenarios, there is a bad outcome
26
The trolley problem
- A Do nothing and kill the five people - B Switch the train to another track and kill one man - People find the B to be more immoral, but it may actually lead to a better outcome : moral decision making - C Stop the trolley and save the five people by pushing a large man to his death in front of the trolley. Would you push him? - Although C is a utilitarian responses, many do not choose C due to adverse emotion
27
________ prefrontal lesions lead to less emotional more utilitarian responses
Ventromedial
28
Autism is linked to dfferences in emotional processing, which can lead to more _______ responses
Utilitarian
29
______positive/negative mood leads to more utilitarian responses
Positive
30
People have problems reasoning with syllogisms in which logical validity conflicts with ____
Truth
31
The belief bias
The tendency to think a syllogism is valid if the conclusions are believable - is more dominant on invalid than valid syllogisms
32
Very few people would accept _______ invalid syllogisms as valid, but they did accept ______ invalid ones
Few accepted unbelievable invalid syllogisms as valid, but they did accept believable invalid ones
33
Conditional Reasoning
“If P then Q” statements where P is the antecedent (conditional claim) and Q is the consequence (conclusion) How to test if the conditional statement “If it is raining, I will get wet” is valid? * What happens if Q is true? If I am wet, is it raining? not necessarily * What happens if P is false? If it isn’t raining, am I wet? No * What happens if Q is false? If I am not wet, is it raining? No
34
Wason’s task: Conditional reasoning - If a card has a vowel on one side, then it has an even number on the other side, which cards should you flip?
Confirmation bias : * Many do not test this statement correctly : many only turn over E to see if there is an even number on the other side * Very few turn over card ‘E’ and ‘5’ to test if a vowel = even number and if not even then not vowel
35
Confirmation bias
Tendency to seek confirmatory evidence for a hypothesis : forget to look at situation in which it could be false
36
The falsification principle
You need to look for situations that would falsify a rule (conditional statement) * General logical rule to solve: “ If P then Q ”. * Choose the P card (is there a not-Q on the back?) and the not-Q card (is there a P on the back?). Eliminate false statements
37
Familiarity effects
- People show less confirmation bias with less abstract cards * If a person is drinking a beer (P), then the person is over 21 years old (Q) * Cards have age on one side and beverage on the other side Which card(s) do you need to flip to verify this statement? - The “drinking a beer” and “16 years old” Success rate in this went from 33% to 75%
38
The return trip effect
Time judged returning on a route (which is now familiar) is rated as shorter than initial route.
39
Biases
Systematically inaccurate choices that don’t reflect a current situation that come from overuse of heuristics - Heuristics bias how we interpret information and judge frequency : diminish the nuance of our reasoning - Heuristics bias how we make predictions and assess outcomes
40
Interpretation: Representativeness bias
Probability that an item (person, object, event) is a member of a category based on resemblance : if it is a good enough match, I will assume it behaves exactly like the prototype
41
Base-rate neglect
- You randomly select one male from the Canadian population and that male, Adam, wears glasses, speaks quietly and reads a lot. It is more likely Adam is a farmer or a librarian? Most people say librarian because of the representative bias and base rate neglect: ignore important rate information when reasoning * There are more farmers than librarians in Canada
42
Conjunction Fallacy
- False assumption that a greater number of specific facts are more likely than a single fact. (e.g. Linda the bank teller) - **It is always the case that 2 events are less probable than a single event**
43
Conspiracy theories and conjunction fallacy
500 participants read scenarios that included two statements, one with single event and one with conjunction fallacy Scenarios were about three topics: * Participants with conspiracy beliefs more likely to make conjunction fallacies in COVID conspiracy scenarios than other topics
44
The availability bias
The easier it is to remember something, the more likely you’ll think it is to happen in the future (memory-based bias) : We confuse the availability of a memory for frequency E.g. Are there more words in the English language that begin with the letter R or with the letter R in the third letter?
45
Judging our life and the availability bias
Our memories (challenges) are recalled easier than other people’s memories experiences : we have better memories for our life’s obstacles, therefore we think our life is harder than other people
46
Anchoring & adjustment heuristic
Biased by an initial value : will affect how you judge things to come * Participants given a random number between 0 and 100 * “Is this number higher or lower than the percentage of African nations in the United Nations?” * Those who were given a HIGH random number gave greater percent estimates than those given a LOW random number - We even anchor estimates to unrelated information (even when participants told the numbers were random)
47
Gambler’s fallacy
The false belief that a predicted outcome of an independent event depends on past outcomes * We assume outcomes are linked when they are random * Thinking one is due for a ‘win’ after a run of ‘losses’
48
Illusory correlations
Linking two co-occurring events and assuming a relationship * Wearing a “Lucky” jersey when your sport team plays because they won last time you wore it
49
The hot-hand belief
Thinking that a person who experiences success will keep having success, * ‘A winning steak’
50
Post-mortem technique
learning from failures
51
Pre-mortem technique
Anticipate and prevent our mistakes before they result in catastrophe
