convergent thinking
narrow thinking to find single best solution
Kahneman’s System 1
arrive at decisions quickly, intuitive and automatic
Kahenman’s System 2
slower controlled processing, requires effort and analysis
many errors in thinking comes from
over reliance on System 1
representativeness heuristic
judging likelihood of something dependting on how well it matches of represents out prototypes (system 1 error)
availability heuristic
estimate the likelihood of something based on how easily it comes to mind; if more readily available, we judge it as more likely
anchoring heuristic
decision makers anchor on an initial number and fail to adjust sufficiently
sunk cost fallacy
tendency to invest more money or resources after some have already been invested
framing

overconfidence
tendency to be more confident than correct
belief perserverance

which psychologists are defined the different heuristics
Kahneman and Tversky
language

morpheme
smallest unit that carries meaning
semantics
