Summary of Part 1 (re. System 1)
- the “personality” of S1, provides hunches abt what S1 wd do
Characteristics of System 1
- generates impressions, feelings, & inclinations; when endorsed by S2 these become beliefs, attitudes, & intentions
- operates automatically & quickly, w. little or no effort, no sense of voluntary control
- can be programmed by S2 to mobilize attention when a particular pattern is detected (search)
- executes skilled responses & generates skilled intuitions, after adequate training
- creates a coherent pattern of activated ideas in assoc. memory
- links cogn. ease to illusions of truth, pleasant feelings, reduced vigilance
- disting’s the surprising fr. the normal
- infers & invents causes and intentions
- neglects ambiguity, suppresses doubt
- is biased to believe & confirm
- exaggerates emotional consistency (halo effect)
- focuses on existing evidence, ignores absent evidence (WYSIATI)
- generates a limited set of basic assess’ts
- rep’s sets by norms & prototypes, does not integrate
- intensity matching across scales (e.g., size to loudness)
- computes more than intended (mental shotgun)
- sometimes substitutes an easier q. for a difficult one (heuristics)
- more sensitive to changes than to states (prospect theory)
- overweights low probabilities
- shows diminishing sensitivity to quantity (psychophysics)
- responds more strongly to losses than to gains (loss aversion)
- frames decision problems narrowly, in isolation fr. one another
