According to Dr. Travis Bradberry (Coauthor of Emotional Intelligence 2.0) smart people tend to act stupid in the heat of the moment.
"Intelligent people have a reputation for making dumb mistakes, especially in situations that require common sense. The simplicity of these situations and the abundant intelligence of those who tend to muck them up can be downright comical."
But apparently there is a way to avoid making that one dumb mistake in the heat of the moment.
The important thing to take away from all of this is to never underestimate the power of stopping and thinking for just a moment before reacting to a problem. In the heat of an event you are likely to want to jump any hurdle that someone throws at you. Taking a moment to make sure there's not hole on the other side of that hurdle will benefit you in the long run.
