Don’t Step on the Foul Line: On the (Ir)rationality of Superstition in Baseball

Baseball is an exceptionally superstitious sport. But what are we to say about the rationality of such superstitious behavior? On the one hand, we can trace much of the superstitious behavior we see in baseball to a type of irrational belief. But how deep does this supposed irrationality run? It appears that superstitions may occupy various places on the spectrum of irrationality — from motivated ignorance to self-deception to psychological compulsion —depending on the type of superstitious belief at work and on the means of formation and/or maintenance of that belief. In this paper, I first examine the various types of superstitions we find in baseball culture, in an attempt to see what these different kinds of superstitions might have in common. I then lay out a working definition of superstition within a baseball context by examining the general psychology underlying such behavior, in an attempt to ascertain the possible causal and/or motivational reasons for the acquisition of superstitious beliefs and practices in sports like baseball. Finally, I argue that, in addition to superstitions acquired merely via the workings of a type of biasing mechanism, there also appear to be genuine cases of superstition acquisition and maintenance, in which the agent may be said to be actively engaged. I claim that in at least some cases of superstitious belief, it is possible that agents are employing an awareness of their own rational epistemic standards to allow themselves to believe and act irrationally, and that the result of such “pseudo-rational” behavior is perhaps a form of self-deceptive superstitious belief.
