Humans actively sample evidence to support prior beliefs.
Excerpts:
No one likes to be wrong.
Previous research has shown that participants may underweight information incompatible with previous choices, a phenomenon called confirmation bias. In this paper, we argue that a similar bias exists in the way information is actively sought.
The study investigates how choice influences information gathering using a perceptual choice task and finds that participants sample more information from a previously chosen alternative.
Furthermore, the higher the confidence in the initial choice, the more biased information sampling becomes. As a consequence, when faced with the possibility of revising an earlier decision, participants are more likely to stick with their original choice, even when incorrect.
