What follows is just a prologue. If you want to directly hit my thoughts on me being superstitious, surf to the last line :)
A guy named B.F.Skinner once carried out an experiment on pigeons to demonstrate the formation of superstition. He placed a series of hungry pigeons in a cage attached to an automatic mechanism that delivered food to the pigeon “at regular intervals with no reference whatsoever to the bird’s behavior.” His discovery in his own words:
The bird behaves as if there were a causal relation between its behavior and the presentation of food, although such a relation is lacking. There are many analogies in human behavior. Rituals for changing one’s fortune at cards are good examples. A few accidental connections between a ritual and favorable consequences suffice to set up and maintain the behavior in spite of many unreinforced instances. The bowler who has released a ball down the alley but continues to behave as if she were controlling it by twisting and turning her arm and shoulder is another case in point. These behaviors have, of course, no real effect upon one’s luck or upon a ball half way down an alley, just as in the present case the food would appear as often if the pigeon did nothing — or, more strictly speaking, did something else.
More on this and its connection with me and my being superstitious here.
