Document Summary
The way we word google searched, questions, etc. Biased assimilation - if you believe something, you assimilate new information in a biased way. New info that fits your belief is accepted readily; contradictory info is viewed critically. Lord, ross, lepper (1979): how people react to mixed evidence relating to capital punishment. Ditto, lopez (1992): how people react to diagnostic tests for a genetic disorder. Those who believe in it, keep dipping the paper back in for longer. However after pulling back: you said absolutely certain 4 times, how many of those times do you think you"re right? 3 -- now reconsidering their estimate. Planning fallacy: packing bag for how much work will get done, etc. thinking from the inside, shove a bunch into backpack. Individuals within a population show variability along numerous physiological, psychological, and behavioral traits. At least some of this variability is heritable.
