Self-delusion January 14, 2017

I’m reading Steven Pinker’s The Better Angels of Our Nature.  It’s an enormous and thorough work on the decline of violence.  Each chapter could really be a book on it’s own, and it’s taking me a really long time to work through it.

A day or so ago, though, this sentence jumped out at me.  It’s in a section where he’s discussing why humans tend to think they are more competent, smarter, and luckier than they actually are:

“… Positive illusions are a bargaining tactic, a credible bluff.  In recruiting an ally to support you in a risky venture, in bargaining for the best deal, or in intimidating an adversary into backing down, you stand to gain if you credibly exaggerate your strengths.  Believing your own exaggerations is better than cynically lying about it, because the arms race between lying and lie detection has equipped your audience with the means of seeing through barefaced lies.” (pg 512)

Hmm.  I’ve been looking for reasons why humans tend to be so good at self-delusion, and this idea could factor into the explanation.  But its validity would hinge on humans being reasonably good at detecting lies.  I’m not convinced that they are, especially given recent politics.

What do you think?
