Sample bias: I feel that so many subtleties are lost because people don't generally realize that their observations/anecdotes/experiences are biased.
If I see a steak on my plate, I can't conclude that there is no world hunger.
If I see a snowball, I can't conclude that there is no global warming.
If I've never experienced racial bias against me, I can't conclude that it does not happen to other people.

Edit: for clarity.
