Question

When people fear boarding a plane because of a recent terrorist attack, while ignoring the fact that the likelihood of experiencing a terrorist attack while aboard a plane is extremely small, this heuristic is at work?

Answer 1

It is small only if you are not involved in such an incident. If you are, then it is extremely large. 

First  hand experience is what I would give as the answer. If I am wrong leave a message for me, and I will have my answer deleted.
