Studies that use unrealistic optimism update#
These findings indicate that optimism is tied to a selective update failure and diminished neural coding of undesirable information regarding the future.

However, highly optimistic individuals exhibited reduced tracking of estimation errors that called for negative update in right inferior prefrontal gyrus. Distinct regions of the prefrontal cortex tracked estimation errors when those called for positive update, both in individuals who scored high and low on trait optimism.
Studies that use unrealistic optimism code#
This selectivity was mediated by a relative failure to code for errors that should reduce optimism. Participants updated their beliefs more in response to information that was better than expected than to information that was worse. We examined this question and found a marked asymmetry in belief updating. How people maintain unrealistic optimism, despite frequently encountering information that challenges those biased beliefs, is unknown. Unrealistic optimism is a pervasive human trait that influences domains ranging from personal relationships to politics and finance.
