Partisan Reasoning and Evolution

From p. 32 of Jonathan Rauch’s forthcoming book The Constitution of Knowledge:

Think of it this way: humans are equipped with some of evolution’s finest mental circuitry to protect us from changing our minds when doing so might alienate us from our group. We have hundreds of thousands of years of practice at believeing whatever will keep us in good standing with our tribe, even if that requires denying, discounting, rationalizing, misperceiving, and ignoring the evidence in front of our nose.

This explains much of modern politics, and is one reason I highly recommend avoiding cable news. Some of the talking heads’ performance routines are impressive. But they are seeking peer approval, not truth or understanding.
