An interesting article from Scientific American about the reason why God, ghosts, and conspiracy theories exist.

“The problem is that we did not evolve a baloney-detection device in our brains to discriminate between true and false patterns.”

And thus we are saddled with religion, making the sane world under the control of idiotic crackpots who actually seem to believe the bullshit they spew.  The sane people of course realize that you can’t reason with the insane, but instead of drowning them in the tub, we allow them to run things in the vain hope that they will leave us alone.
