If you could wave a magic wand and make one commonplace myth or misconception disappear, what would it be?

While this isn't really the sort of question we like to handle around here (see rules), it would be appropriate for our Friday Free-for-All where the rules a little more lax. I'd be interested in seeing what others have to say on the topic so be sure to come back Friday and ask again in that weekly feature.
