"At bottom, you see, we are not Homo Sapiens at all. Our core is madness. The prime directive is murder. What Darwin was too polite to say, my friends, is that we came to rule the earth not because we were the smartest, or even the meanest, but because we have always been the craziest, most murderous motherfuckers in the jungle." ~Headmaster Ardai (The Head) in Stephen King's Cell
Makes a lot more sense than "we survived because we're smart." Sorry folks, we're a bunch of idiots, and if you doubt it you're one of 'em. Or rather, as Tommy Lee Jones's character said in Men in Black, "The person is smart, the people are stupid." Face it, we're a bunch of pitchfork-wielding, panicky maniacs whenever something frightens us. And a lot of things frighten us if history is any judge.
Or even a trip to the local grocery store (which is more often becoming a "Super Chain" of some variety or another). I mean really, how often does someone have to scan at item before they realize "Hey, it's not entered in the computer"? Or for that matter...how often do you have to press the buttons on the remote before you realize you may need to change the batteries?
From what I've observed, it's quite a bit more than the number of licks it takes to get to the center of a Tootsie Roll Pop.
