Problem 5 Flashcards

1
Q

Representativeness heuristics

A

Is used when people judge the probability that an object/event A belongs to a class/process B

–> if it is similar to most of the others of the Class/process then it is considered representative

Q

Conjunction fallacy

A

Refers to the mistaken belief that the combination of 2 events is more likely than one of the two events on its own

–> involves the representativeness heuristic

ex.: It is more likely for Linda to be a bank teller AND active in a feminist movement than her just being a bank teller

Q

We can distinguish between 2 different mechanisms when it comes to availability heuristic.

Which are those ?

A

1. Availability by recall mechanism

–> info that you have

2. Fluency mechanism

–> how easily you can retrieve info

Q

What was Tversky + Koehlers key assumption for their support theory for the availability heuristic ?

A

Any given event will appear more or less likely depending on how it is described

–> the subjective probability of any given possibility will increase when it is mentioned explicitly

Q

Recognition heuristic

A

Is used when individuals recognize one object but not the other, so no other info influences the decision

ex.: Is cologne or Herne a bigger city? - Cologne because more famous

Q

Why do people use the recognition + take-the-best heuristics strategy ?

A
  1. Heuristics often produce accurate predictions
  2. It takes the least time to access + is the least cognitive demanding

Q

Dual process model

(Kahnemann)

A

Suggest that there are 2 systems involved.

S1: Intuitive, immediate, automatic

–> heuristics

S2: analytical, controlled, rule-governed

Q

Limitations on the dual process model ?

A
  1. Assumes that most people rely exclusively on S1, whereas base rate info is used a lot too
  2. Importance of parallel processing

Q

Expected Utility theory

A

When we need to chose between simple options, we asses the expected utility

–> we always try to maximize utility, which is the subjective value we attach to an outcome

Q

What are the main assumption of the prospect theory ?

A

1. Loss aversion

  • individuals are more sensitive to potential losses than gains

2. demonstrates that people think in terms of expected utility relative to a reference point, rather than absolute outcomes

–> e.g.: if two choices are put before an individual, both equal, with one presented in terms of potential gains and the other in terms of possible losses, the former option will be chosen

=> more adequate than expected utility theory, says its incorrect

Q

Dominance principle

A

States that if option A is as good as option B in all regards and better than B in at least one regard, then A should be preferred to B

–> applies always according to expected utility theory

17
Q

According to the prospect theory, when should framing effects be found ?

A

Only, when what is at stake has real value for the decision maker

–> loss aversion doesn’t apply if you don’t mind taking losses

18
Q

What do framing effects depend on ?

A

The recipient of the message + whether the message is positively or negatively framed

19
Q

Unbounded rationality

A

Assumes that all relevant info is available for use by the decision maker

–> engaging in a process of optimization

20
Q

Optimisation

A

Is a process where the best choice/decision is made

21
Q

Bounded rationality

A

Producing reasonable solutions to problems in spite of our limited processing ability by using various short-cut strategies

–> satisfycing

22
Q

Satisfycing

A

Is a heuristic where individuals consider various options one at a time + select the first one meeting their minimum requirements

–> choice might not be the best one

ex.: deciding who to marry (satisfying + sufficing)

23
Q

Elimination-by-aspects theory (Tversky)

A

States that decision makers eliminate options by considering one relevant attribute/aspect after another

ex.: When buying a house first considering location + eliminating houses out of the location, then price, and so on

24
Q

Why is human decision making nothing like the ideal described in unbounded rationality ?

A
  1. We typically focus on only some of the available info because of our limited ability to process + remember info
  2. Our decision making is irrational
    * our preferences can easily be changed, as they are influenced by the order in which info is presented + options we choose (priming)
25
Q

Uber is built on the concept that their drivers can choose their working hours.

How do they motivate/manipulate their drivers into working longer hours ?

A
  1. Goal targeting via the app

–> when trying to log off they are reminded that they are close to a money goal

  1. Use their drivers data + algorithms to exploit their weaknesses
26
Q

Endowment effect

A

Refers to the tendency for owners to value their objects more than potential buyers do

27
Q

What is the most common explanation for the endowment effect ?

Does it still hold true ?

A
  1. Loss aversion
  2. No, there has been new evidence that there might be cultural differences in its extent, and thus might have to do with an automatic association between the object + the self
    e. g.: collectivistic vs independent
28
Q

A newer explanation of the endowment effect stresses cultural differences in its extent.

Where do these cultural differences stem from ?

A

From the intrinsic tendency to enhance the self, when associating the object with the self, this boosts the objects perceived value relative to when the object is not owned

–> as the eastern culture is more collective vs the western more individualistic - the endowment effect is larger in western cultures

29
Q

Loss aversion

A

Refers to the idea that people weigh losses more heavily than gains

30
Q

People choose differently when they choose for themselves vs for others.

To which extent ?

Why ?

A
  1. When choosing for others we tend to seek more info
  2. Choosing for others lessens loss aversion
  3. When choosing for the self one is willing to select a higher risk
31
Q

Omission bias

A

People judge harmful actions (things we already did) as worse than equally harmful inactions (things we didn’t do)

32
Q

There are 3 rules for the “take the best” heuristics.

Which are they ?

A

1. Search rule

  • search cues, name recognition

2. Stopping rule

  • reconsidering first heuristics

3. Decision rule

  • choose outcome
33
Q

Why do we ignore base rate info ?

A

Because we tend to use heuristics

–> we don’t like to do calculations, so we ignore the frequency reports

34
Q

Causal model

A

Describes causal mechanisms of a system

–> causes less base rate effect + makes our judgments more accurate

35
Q

Loss neutrality

A

Not favoring one option over another, concerning losses + gains

–> opposite to loss aversion

36
Q

Impact bias

A

Overestimation of the intensity + duration of negative emotions

37
Q

Action bias

A

Refers to the tendency to prefer action over inaction

38
Q

Rational emotional model

A

Choosing the options that will reduce our negative emotions, in decision making

ex.: fear, regret

39
Q

Social functionalist approach

A

Social context is important because people need to justify their actions/decisions

–> ignores loss aversion + emotions

–> protective mechanism

40
Q

Multi attribute utility theory

A

When too many options/info are available this model tries to compromise among them

  1. Identifying the attributes that are relevant
  2. Deciding how to weight them
  3. Listing all options
  4. Rate each option
  5. Obtaining a total utility + selecting the best ones
41
Q

Model of selective exposure

A
  1. Having a preference for things that confirm my pre-existing views
    * avoiding things that conflict with my views
  2. This increases selective exposure when there’s high defense motivation

–> occurs when we have little info

same as conformation bias

42
Q

5 phases of decision making (Galotti)

A
  1. Setting goals
  2. Gathering info
  3. Structuring the decision
  4. Making a final choice
  5. Evaluating the decision

–> order is flexible, when indecisive/unhappy with outcome

43
Q

Unconscious thought theory

A

Unconscious thinking is better than conscious thinking when making complex decisions

–> as seen by incubation effects

44
Q

Nudging

(Thaler)

A

Refers to an aspect of choice architecture that alters peoples behavior without forbidding any options

–> assumes that positive reinforcement + indirect suggestions influence behavior + decision making

ex.: putting a small fly in urinal, so men aim at the fly and don’t pee beside the urinal
