I have this feeling it's a bit of the random chance that our evolution grants us. Some folks get a dice roll that makes them just a tiny bit more afraid of the dark. Some less. Sometimes there's abundant food beyond the dark. Sometimes there's a bear. People aren't that simple though. Some people realize there might be a bear, and encourage other people to explore the dark looking for the food. Some other people might go, 'hey wait sometimes there are bears in the dark'. If you want to call the warning pessimism, well, that's your right, I guess. But it sure seems useful to me.
