Thinking, Fast and Slow Quotes

“Systems 1 and 2 are both active whenever we are awake. System 1 runs automatically and System 2 is normally in a comfortable low-effort mode, in which only a fraction of its capacity is engaged. System 1 continuously generates suggestions for System 2: impressions, intuitions, intentions, and feelings. If endorsed by System 2, impressions and intuitions turn into beliefs, and impulses turn into voluntary actions. When all goes smoothly, which is most of the time, System 2 adopts the suggestions of System 1 with little or no modification. You generally believe your impressions and act on your desires, and that is fine—usually.”

“Characteristics of System 1: • generates impressions, feelings, and inclinations; when endorsed by System 2 these become beliefs, attitudes, and intentions • operates automatically and quickly, with little or no effort, and no sense of voluntary control • can be programmed by System 2 to mobilize attention when a particular pattern is detected (search) • executes skilled responses and generates skilled intuitions, after adequate training • creates a coherent pattern of activated ideas in associative memory • links a sense of cognitive ease to illusions of truth, pleasant feelings, and reduced vigilance • distinguishes the surprising from the normal • infers and invents causes and intentions • neglects ambiguity and suppresses doubt • is biased to believe and confirm • exaggerates emotional consistency (halo effect) • focuses on existing evidence and ignores absent evidence (WYSIATI) • generates a limited set of basic assessments • represents sets by norms and prototypes, does not integrate • matches intensities across scales (e.g., size to loudness) • computes more than intended (mental shotgun) • sometimes substitutes an easier question for a difficult one (heuristics) • is 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 from one another*”
