Superstitious behaviour

Many of us have some superstitious behavior, or acts that we believe are somehow tied to the results of a certain event. This usually is not consistent with logical reasoning but we continue to perform these acts anyway. For this discussion, identify a superstitious behavior of your own or someone you know and do the following:

Initial post:
Describe the superstitious behavior, how it�s performed, and in what context.
Based on chapter 8 and chapter 9, discuss what fallacies or biases are behind such behavior.
Search for a scholarly article on superstitious behavior and propose a reason why the person may continue to do it even if he/she is aware that the behavior is not really related to the event outcome.
