decision making Flashcards
what perspective models do economics rely on for decision making
- expected value: normative, ideal performance under ideal circumstances, ppl weight options then choose one with highest expected value, deals with money
- expected utility: ppl choose alternative with highest utility/benefit
a ____ model tells us how we ‘ought’ to make decision and a ___ model shows what people actually do
a) descriptive, perspective
b) descriptive, performance
c) perspective, descriptive
d) detailed, performance-based
c) perspective, descriptive
loss aversion
- place high value on what is yours, don’t like to lose
- if you lose more than you gain don’t take the deal
- avoiding loss permeates judgement
loss aversion tends to maintain the _____ ____
- status quo
anchoring
- when making estimates, people start with initial estimate then adjust it
- the position you start from influences adjustment
framing effects
- the way a problem is framed changes how options are evaluated
risk aversion
- depending on how info is presented, different options seem less risky
availability heuristic
- judgements based on which relevant instances can be retrieved from memory
- likelihood of event is evaluated on how easy it is to come up w examples
heuristics
- strategies that can be applied easily to wide variety of situations that often lead to reasonable decisions
representative heuristic
- if something appears to fit a category, you will judge them to be a part of the category
implicit bias
- discriminatory biases based on implicit attitudes/stereotypes
- automatic, outside of person’s awareness
- resistant to extinction
- formed through experiences
what impacts how a person makes a decision
- implicit bias (stereotypes)
- heuristic (representative and availability)
- framing effects
- risk aversion
- loss aversion
- anchoring
_______ racism/sexism is when bias is unstated and hidden
Benevolent
how are biases/stereotypes formed
- social learning process (parents/significant other/media)
- categorization processes (cognitive efficiency, understanding/prediction, enhance social identity)
gambler fallacy
- belief that certain random events are less or more likely to occur based on outcome of previous events (ie flipping a coin)
biases vs heuristics
- biases: systemic errors arising from use of heuristic in decision making
- heuristics: simple cognitive rules, easy to apply, yield acceptable decisions, can lead to errors
hindsight bias
- once facts of a case are learned, we tend to believe we knew it all along
overconfidence bias
- confidence in decisions rises as more info is collected
- most extreme in tasks of higher difficulty
_______ bias is when more vidi events are remembered better, and we base judgement on how often they occur
saliency bias
familiarity bias
- judge event as more frequent/important bc it is more familiar in memory
illusory correlations
- in any random sequence, patters appear to be meaningful
- occur bc brain is constructed to search out meaningful patterns/make sense of experiences
regression to the mean
- as sample size increases, sample is more likely to represent the population
two types of reasoning
- inductive: make prediction, generate knowledge, facts>generalized
- deductive: how ppl have a tendency to think about certain things, general>specific, more reasoning used
Syllogisms
- basic reasoning puzzle/prob you have to solve
- given often 2 premises, judge if conclusion is true based on them
- ex all thai food is yum, spring rolls are yum, therefore spring rolls are thai food
Belief bias (syllogism)
- tendency to think that a syllogism is valid if conclusions are believable
Difference between true and valid (syllogism)
- true: the way the world as we know it works
- valid: logically follows from premises
why do ppl get confused on true/valid syllogisms?
- we judge conclusion on what we know abt the real world
- we are biased to see what we believe to be true to be logically valid as well
what makes the distinction between true and valid syllogisms hard?
- quantifiers: how does it apply?
- Negation: contradiction
propositional reasoning
- assertion/proposition that is tested
- have a statement, answer if its true or not
two ways of expressing propositional reasoning
(hint: think latin)
- Modus Ponens: mode that affirms. ex if p, then q. p. therefore, q
- modus tollens: way in which this is denied. ex. if p, then q. q is false. therefore, P is false.
which modus is used to test a rule by finding where the rule is broken?
modus tollens
why is modus tollens more difficult to understand than modus ponens
- falsification principal
- coming up w tests that negate rule is harder
confirmation bias
- tendency to only look for info that confirms belief and ignore what disproves it
how to fight against confirmation bias
- falsification principal: look for situations that falsify the hypothesis/what you are testing
what affects reasoning
- general world knowledge
- experience
