So, I'm browsing around, and find a creationist site that made an interesting (if unintentionally ironic) argument:

By the way, not being able to correct false thinking is another blow against evolution. The theory of natural selection should conclude that humans should be able to easily correct false thinking because it is the most beneficial approach, but they can't.

Now, when I find something weird about any animal, I usually look for the evolutionary answer (yep...that's right guys...I am BIASED). I confess to having a little trouble with this one (in fairness, it's been 2 minutes, and I'm drunk).

Anyone care to expound on the benefits of the persistence of beliefs?
