We in science tend to take a more evidence-based approach to things, yet we're not immune to these sort of superstition. During this year's NHL playoffs, you would still hear the majority around here talking about not watching the game at a certain location because 'they lost last time we were there', or wearing a particular t-shirt for good luck. Clearly the outcome of a sporting event is beyond the control of the viewer at home, regardless of what they're wearing (either that or the collective fan-base of Anaheim is much better at harnessing this voodoo than those of us in Ottawa), yet we still go to some lengths to set the perfect conditions. This is called illusion of control, a widespread effect and the basis for most superstitions.
Some may say this is evidence (anecdotal as it is) that men and women of science believe in some sort of higher power (you know, the Hockey Gods). In a study done a few years ago it was shown that interest in sports correlated strongly with belief in sports superstitions, but not with scores on the Paranormal Belief Scale (PBS). Not surprisingly, scores on the PBS also correlated positively with beliefs in sports superstition. I don't know if the leap can be made that the superstitious sports fans here also hold belief in the paranormal, but I don't have time to address that - I have my pre-tissue culture ritual to get to.
