Q

stages of decision making

- theory of natural decision making

A
  1. setting goals: goals influence decisions; decisions are steps toward something you want to accomplish
  2. gathering information: know what the options, consequences are
  3. decision structuring: organise all information (listing options + criteria for deciding among them)
  4. making final choice
  5. evaluation
    √ flexibility in phase order (if struggling, returning to previous phases)

Q

cognitive illusions

A

= errors of cognition that come about for understandable reasons and that provide information relevant to understanding normal functioning –> systematic biases
- heuristics = rules of thumb; strategies that ignore part of the information with the goal of making decisions more quickly

Q

cognitive illusions

- framing effect

A
  • description frames the decision (e.g. 2 gas stations)
  • “context effect” in decision making
  • changing description can lead people to adopt different reference points
  • loss aversion

cognitive illusions

- sunk cost effects

A

= greater tendency to continue something once one has invested in it

Q

cognitive illusions

- hindsight bias

A

= tendency to exaggerate what could’ve been anticipated in foresight when looking back in hindsight
- once you know how a decision turned out, events leading up to outcome seem more inevitable than they really are

Q

cognitive illusions

- omission bias

A

= tendency to prefer inaction to action when engaged in risky decision making
- anticipated regret: greater when unwanted outcome caused by own actions rather than inaction
- status quo bias = decision avoidance; preference for maintaining the status quo (present state) rather than acting to change one’s decision
x action bias = don’t just sit there, do something

Q

cognitive illusions/bounded rationality

- saitsficing

A

= strategy that aims for a satisfactory/adequate result, rather than the optimal solution

  • “good enough” rather than expending effort/resources on finding best possible/optimal choice
    1. satisficers = people content with making reasonably good decision; were happier and more optimistic, greater life satisfaction, less regret (not found in Chinese)
    2. Maximisers = perfectionists

Q

cognitive illusions

- fast-and-frugal heuristics

A

= heuristics involving rapid processing of relatively little information
- take the best, ignore the rest
x why do we have capacity of logical reasoning if we could always follow gut feelings
x more complex than suggested –> often not sufficient knowledge of validities

Q

fast-and-frugal heuristics

- availability heuristic

A

= instances that are more easily thought of/accessible, stand out more in one’s mind

  • own behaviours more prevalent to us than that of others
  • failure to include base rate info in probability estimation
  • availability by recall (number of instances recalled) vs. fluency mechanism (how easy it WOULD be to recall without actually retrieving from memory)

Q

fast-and-frugal heuristics

- representativeness heuristic

A

= representatives/typical members of a category are encountered more often

  • failure to include base rate info
  • mistaken belief in the law of small numbers: people expect small sample to show same proportions as large sample
  • gambler’s fallacy: mistaken belief that if something happens more frequently than normal during a given period, it will happen less frequently in the future
  • conjunction fallacy: mistaken belief that the probability of a conjunction of 2 events (A & B) is greater than the probability of one of them

Q

fast-and-frugal heuristics

- recognition heuristic

A

= using knowledge, that only one out of two objects is recognised, as basis for making a judgment; selecting object that is recognised in preference to the one not recognised (recognise cologne not Herne, decide cologne is bigger)
- exploits lack of knowledge
x more complicated than assumed –> consider why they recognise and object + decide then whether to use

Q

utility models

A

= we try to maximise utility (subjective value we attach to an outcome)

  • normative models = define ideal performance under ideal circumstances
  • prescriptive models = show how we ought to make a decision (= consider that circumstances aren’t ideal and show how to best decide)

Q

utility models

- expected utility theory

A

= trying to assess the subjective utility of certain objects

  • normative model: ideal performance under ideal circumstances
  • expected value (EV= ∑(p×v)): determine to choose the one with the higher value & see how much money you should spend
  • expected utility (EU= ∑(p×u)) = (probability of a given outcome) x (utility of the outcome): captures ideas of happiness, pleasure & satisfaction that comes from achieving goals (= psychological rather than monetary value)
20
Q

limitations of expected utility theory

A

x calculation of EU difficult: info about several aspects of the decision must be integrated (various factors and goals)
x only accounting for making final selection from a set of alternatives –> not making decisions with “status quo vs. make a change” option
x doesn’t describe processes by which people structure a decision (= gather info and lay out possibilities + parameters)

21
Q

utility models

- multi-attribute theory (MAUT)

A
  • ideal strategy –> bounded rationality (more realistic)
    1. break a decision into independent dimensions
    2. determine relative weights of each dimension (= subjective value)
    3. list all alternatives
    4. rank alternatives along dimensions
    5. multiply ranking by weighting of each alternative to determine final value
    6. choose alternative with highest value
  • normative model: if people follow MAUT they will maximise own utility in a way that is best for achieving all their goals
  • dimensions must be chosen carefully
  • person would be willing to choose an alternative that was not highest on the highest ranked dimension when the relative position on other dimensions compensates for that
22
Q

limitations of multi-attribute utility theory

A

x elimination by aspects (descriptive model): when decision makers have too much info to deal with they don’t take all dimensions into account but rather select one factor, pick a threshold value and everything that exceeds that threshold value is tossed
x Homo economicus assumed: too rational
x procedure too complex
x set of relative dimension can not always be worked out; not clearly separate from each other

23
Q

descriptive models

A

= simply detail what people actually do when they make decisions (= actual performance); what people ACTUALLY do

24
Q

descriptive models

- bounded rationality

A

= people are as rational as their processing limitations permit

  • produce reasonable/workable solutions to problems in spite of our limited processing ability (heuristics)
  • unbounded rationality = if all the information you need, could choose best choice
  • Simon
25
limitations for rational decision making
- cognitive constraints: limited capacities for information processing - environmental constraints: not enough information about alternatives + consequences; limited time/resources - -> use of heuristics
26
descriptive models | - image theory
- pre-choice elimination = ask themselves whether a new goal/plan/ alternative is compatible with 3 images 1. value image: decision maker’s values, morals, principles 2. trajectory image: goals & aspiration for the future 3. strategic image: way in which decision maker plans to attain his/ her goals - incompatible with at least one of images drop out from further consideration
27
descriptive models | - recognition-primed decision making
= experts most likely rely on intuition, mental simulation, making analogies, recalling/creating stories when deciding; compare/recognise current situation to one encountered before - expert decision making - relevant when decisions must be made rapidly - when situation familiar/typical: experts match situation to learned patterns of information stored in LTM (pattern recognition) --> retrieval of a single option --> mental stimulation --> if imagined outcome satisfactory that option determines actions - when situation not familiar: diagnose situation further (story building, more data) - Klein
28
descriptive models | - prospect theory
= decisions based on evaluation of potential value of losses and gains, using heuristics - editing: identify reference point (subjective), generally representing current state - evaluation: loss aversion - Kahneman; graph x partly explains value function x does not include social/emotional factors x framing depends on individual differences x probability of rare events is underrated
29
descriptive models | - constructivist approach
= cultural representations are dynamic schemas rather than ever-present personality traits; switch between cultural frames in response to situational cues - explains how people can be fluent in more than one culture without simply blending their biases
30
self-other decision making
= making choices for others involves less loss aversion than making choices for self - making decisions for others gives us a feeling of power which makes us less sensitive to losses + seek more info when making decisions for others - omission bias greater for self
31
self-construal priming on risk taking
= everybody has 2 co-existing selves in their memory: one independent + one interdependent - cultural differences stem from likelihood of sampling one or the other (depending on social role & situation) 1. primed on an interdependent self: less likely to take social risks than those primed on independence 2. primed on interdependence: more likely to take financial risks - cushion hypothesis: social network acts as safety net; riends & family members offer a cushion that lessens effect of financial loss but magnify embarrassment of a social misstep
32
dual-process theory | - Kahneman
system 1: intuitive, automatic, effortless; heuristic-based system 2: analytical, controlled, rule-based; more concscious - serial processing x assumes that people mostly use system 1 x oversimplification: people also rely on base-rate information in system 1/rapid judgments x people can show strong biases even when using system 2 --> error-prone performance not only system 1 x serial processing is difficult to detect
33
endowment effect
= tendency for owners (potential sellers) to value objects more than potential buyers; simply owning an object can enhance its perceived worth = self-object-association + self- enhancement bias = enhancement of object’s perceived value - smaller effect for Easterners (= faster in switching technologies etc.) --> interdependent self: self-criticising --> independent self: self-enhancing
34
natural frequency hypothesis
= better/more accurate judgment with natural frequencies than percentages - people are naturally equipped to think about frequencies rather than probabilities x benefits of frequency formats do not occur when using steps to avoid obvious version x truly natural sampling may not be possible at all x high demands on memory
35
rational-emotional model
= account for decision avoidance; decision Making based on rational factors - omission + status quo bias: explained with regard to regret and fear (= fear can be reduced when someone decides not to make a decision at that time)
36
social functionalist approach
= takes into account social context of decision making | - people = intuitive politicians --> justify decisions to others
37
nudging
= steer people in a particular direction while still allowing them to go their own way (a subtle way of influencing behaviour); help them make good decisions without coercing them - alter “choice architecture” (= background against which choices are made) - default rules/ options: option a decision maker will obtain if he/she does nothing - -> establish status quo/reference point for counting changes as losses or instead as gains - -> depends on the costs of the decision + the cost of error - -> often thought to be most effective nudge (fail when strong antecedent preferences or opposed with counternudges) - Thaler - uber tricks
38
nudging ineffective when…
x based on inaccurate understanding of behaviour x info is too confusing/complex (unaffected by it) x people show reactance: reject an official effort to steer just because it’s an official effort to steer x they have short-term effect x it influences desired conduct + produce compensating behaviour (rebound effect) --> nullifies overall effect
39
responses to failed nudging
1. do nothing: failure might show that there is no problem at all 2. nudge better/different when convinced that people’s choice is not promoting their welfare 3. fortify/defend effects of nudge with a more aggressive approach (e.g. counter-counternudges or bans)
40
availability heuristic | - support theory
= event appears more/less likely depending on how it is described; distinguish between events and descriptions of those events - more explicit event descriptions have greater subjective probability, BECAUSE 1. explicit description often draws attention to aspects of the event less obvious in non-explicit description 2. memory limitations prevent people from remembering all the relevant info if it is not supplied x oversimplification x explicit descriptions can reduce subjective probability if they lead individuals to focus on low-probability causes; if they are hard to understand
41
dual-process theory | - logical intuition model
= there is rapid, intuitive processing (system 1) of heuristic and intuitive logical processing (base rates) which is sometimes followed by deliberate system 2 processing improvements to dual-process: √ heuristic and base-rate information can both be rapidly accessed through intuitive processing
42
prospect theory | - loss aversion
= treat losses more seriously than gains of the same amount (care more about losing than winning a dollar) - loss neutrality = participants do not favour one option over other unless stakes are high
43
bounded rationality | - elimination-by-aspects theory
= decision makers eliminate options by considering one relevant attribute/aspect after another √ useful at early stages
44
elimination-by-aspects theory | - two-stage theory
= modified version of elimination-by-aspect 1. initial stage: elimination-by-aspects --> only options meeting certain criteria are retained - reduce options to manageable number 2. second stage: detailed comparisons of patterns of attributes of retained options - -> few options switching to more complex strategy (multi-attribute utility theory)
45
different search strategies
1. focused search: focus on small number of carefully selected potential options a. correlated positively with satisfaction with option 2. exploratory search: taking into account several options making use of several information sources 3. haphazard search: non-strategic approach; resembles trial and error a. correlated negatively
46
unconscious thought theory
= conscious thinking is constrained by limited capacity of consciousness; unconscious thinking is better at integrating large amounts of information - conscious thought can follow strict rules (well suited to rule-based problems) - unconscious though better when decision complex - optimal: combination of conscious + unconscious thought x inconsistent findings x rely heavily on intuitive processes
