省得每次都要放狗搜。出自：Jonah Lehrer's The Frontal Cortex Blog:

We like to believe that the gift of human reason lets us think like scientists, so that our conscious thoughts lead us closer to the truth. But here’s the paradox: all that reasoning and confabulation can often lead us astray, so that we end up knowing less about what jams/cars/jelly beans we actually prefer. So here’s my new metaphor for human reason: our rational faculty isn’t a scientist – it’s a talk radio host. That voice in your head spewing out eloquent reasons to do this or do that doesn’t actually know what’s going on, and it’s not particularly adept at getting you nearer to reality. Instead, it only cares about finding reasons that sound good, even if the reasons are actually irrelevant or false. (Put another way, we’re not being rational – we’re rationalizing.)
