Self-deception

Hey guys,

This is a request asking you to keep your eyes out for any literature directly or indirectly related to self-deception. I'll probably have to wait until I leave FAU to start a self-deception project, but at least this gives me time to get my thoughts together.

I just found this study in Proceedings.
"Overconfidence has long been noted by historians and political scientists as a major cause of war. However, the origins of such overconfidence, and sources of variation, remain poorly understood. Mounting empirical studies now show that mentally healthy people tend to exhibit psychological biases that encourage optimism, collectively known as ‘positive illusions’. Positive illusions are thought to have been adaptive in our evolutionary past because they served to cope with adversity, harden resolve, or bluff opponents. Today, however, positive illusions may contribute to costly conflicts and wars. Testosterone has been proposed as a proximate mediator of positive illusions, given its role in promoting dominance and challenge behaviour, particularly in men. To date, no studies have attempted to link overconfidence, decisions about war, gender, and testosterone. Here we report that, in experimental wargames: (i) people are overconfident about their expectations of success; (ii) those who are more overconfident are more likely to attack; (iii) overconfidence and attacks are more pronounced among males than females; and (iv) testosterone is related to expectations of success, but not within gender, so its influence on overconfidence cannot be distinguished from any other gender specific factor. Overall, these results constitute the first empirical support of recent theoretical work linking overconfidence and war." [Overconfidence in wargames: experimental evidence on expectations, aggression, gender and testosterone]

I'm not particularly interested in overconfidence, but it is a form of self-deception.

Thanks.

Cool study. I'd like to think more about this sort of thing, like circustances when you'd expect women to be overconfident, but I've got too much reading to do today. ;) BUT, in conjuction with the abstract I posted below, I wanted to mention the importance of highlighting instances when self-deception would not be beneficial, or when accuracy is necessary. I'm sure you've thought about all of this many times over, but I just thought I'd mention it because it makes your argument all the much stronger.
