Abstract

Unrealistic optimism is a pervasive human trait that influences domains ranging from personal relationships to politics and finance. How people maintain unrealistic optimism, despite frequently encountering information that challenges those biased beliefs, is unknown. We examined this question and found a marked asymmetry in belief updating. Participants updated their beliefs more in response to information that was better than expected than to information that was worse. This selectivity was mediated by a relative failure to code for errors that should reduce optimism. 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. However, highly optimistic individuals exhibited reduced tracking of estimation errors that called for negative update in right inferior prefrontal gyrus. These findings indicate that optimism is tied to a selective update failure and diminished neural coding of undesirable information regarding the future...

What this says is that people will easily believe and remember good news but will underestimate the possibility of anything bad happening even when given valid reasons to change their thinking and/or prepare.

I think my big-city son was mild mannered compared to the missionaries I've met. I don't know what they put in the water in Idaho, but the stories those boys would tell about their risky adventures would raise my hair on end. I would have been an insane mama if my son had done a tenth of what the elders told me. Even on their mission, we've had injured elders from silly risks playing on PDay, fooling around outside while tracting, etc. Boys!

You can do more in Idaho without it killing you. :D Or maybe I should say someone killing you. In cities you really have to watch them ever second. Not so much out on a farm. :D

hmm i'd either guess to get them out of the nest or as a population control mechanism :P
