Why do we see faces in clouds, but not clouds in faces:

Nicholas Kristof examines the reasoning behind human folly in today's New York Times. It turns out our brains are programmed to fear snakes, even harmless ones, but we find it almost impossible to recognize the dangers in something as profound as climate change. According to Daniel Gilbert, professor of Psychology at Harvard and quoted heavily by Kristof in the op-ed piece, the human brain is programmed for social issues, and that's why we see faces in clouds but not the other way around.

Kristof points out that we react quickly when the threat is imminent but we tend to dismiss long term threats. Which reminds me of a boss I once had. He was great in a crisis, so if one didn't exist, he made sure that one did. Eventually, he declared bankruptcy. Fortunately, I'd found another employer before that happened.
