Decision-Making & Reasoning Flashcards
Used to select from among choices or to evaluate opportunities
Judgement and Decision-Making
The earliest models of how people make decisions
Classical Decision Theory
- Decision makers are fully informed. Regarding all options for their decisions and all possible outcomes of their decision option.
- They are infinitely sensitive to the subtle distinctions among decision options.
- They are fully rational in regard to their choice of options.
The Model of Economic Man and Woman
The goal of human action is to seek pleasure and avoid pain.
Subjective Expected Utility Theory
Based on the individual’s judged weightings of utility, rather than an objective criteria.
Subjective Utility
Based on estimates of likelihood, rather than on objective statistical computations.
Subjective Probability
Mental shortcuts that lighten the cognitive load of making decisions.
Heuristics
Types of Heuristics
Satisficing [Satisfying]
Using Probabilities to Make Decisions
Elimination by Aspects
Representativeness Heuristics
Availability Heuristic
Anchoring
Framing
Consider options one by one, and selecting an option that is satisfactory or acceptable.
Satisficing [Satisfying]
We are rational, but within limits
Bounded Rationality
Eliminate alternatives by focusing on aspects of each alternative, one at a time.
Eliminate by Aspects
Judging the probability of an event to (1) how similar it is to the representative population and (2) the degree it reflects to the salient features of the process where it’s generated.
Representative Heuristics
Prevalence of an event or characteristic within its population
Base Rate
Making judgment based on how easily we can call to mind what we perceive as relevant instances of phenomenon.
Availability Heuristic
People adjust their evaluations of things by means of certain reference points.
Anchoring
The way options are presented influences the selection of an option.
Framing
Biases
Illusory Correlation
Overconfidence
Hindsight Bias
Being predisposed to see particular events, attributes, and categories as going together, even when they’re not.
Illusory Correlation
Individual’s overvaluation of her or his own skills, knowledge, or judgment.
Overconfidence
Looking at situation and believed seeing in advanced all the signs and events that led up to an outcome.
Hindsight Bias
Erroneous judgment and reasoning
Fallacies
A mistaken belief that the probability of a given random event is influenced by previous random events.
Gambler’s Fallacy and Hot Hand
Individual gives a higher estimate for a subset of events than for the larger ones.
Conjunction Fallacy
The decision to continue to invest in something simply because one has invested in it before and one hopes to recover one’s investment.
Sunk Cost Fallacy
Don’t always lead to poor decisions because oftentimes, they are right
Heuristic Effects
Prices paid for availing oneself of certain opportunities
Opportunity Cost
Real decisions are created in high-stakes situations and natural environments.
Naturalistic Decision Making
- Premature decision making, caused by group members’ attempts to avoid conflict
- Impairs the quality of decision making
Groupthink
