I was reminded of a time back in college when a friend and I tested the theory that people do not look up as they walk around: We climbed up into a tree (not very high--about 10 feet) in an area of fairly heavy foot traffic, and waited to see if anyone saw us. And, as it turned out, no one did.
Do we only see what we expect to see?
