"Very Superstitious" (like the Stevie Wonder song)

In response to Mariah Key's question, "Talking about ghosts makes me think about superstitions; what truth do you think is behind superstitions?"...

     Last semester I took Logic and Critical Reasoning, and when we were studying fallacies, superstitions came up. I forget the exact name of the fallacy, but there is one in which one event follows another, and individuals assume that the two events are connected. In other words, an example Professor Nnodim used in class is, cheerleaders always wear a blue ribbon in their hair, and for the most part, the football team has a very good season. For one game, for what ever reason, they decide to all wear yellow ribbons. The team suffers an uncharacteristic, brutal loss. Many of the cheerleaders may then swear to never wear the yellow ribbons again, in fear that it might make the team loose.
     It may seem obvious that it is "stupid" to make such an assumption. But, if you examine your life a little closer, you might realize that you adhere to superstitions unintentionally quite often. Do you believe any of these things?

*Friday the 13th is an unlucky day
*to find a 4-leaf clover is incredibly lucky
*to blow out all of the candles on your birthday cake in one breath will make your wish come true
*crossing your fingers makes your wish come true
*to find a penny heads-up brings good luck
*a drowned woman floats face-up, a drowned man floats face-down
*to ensure a happy marriage, a bride must wear something old, something new, something borrowed, something blue
*washing a car will bring rain
*a beginner will always have good luck (beginner's luck)

     Many may say that they do not believe in superstitions, as I do myself, but when they walk under a ladder or see a black cat, they still might remember such a superstition, even if they do not believe it has any truth. Does acknowledging or remembering a superstition mean you do somewhat believe in it?
     Nevertheless, in response to Mariah's question, I do not think there is truth to superstitions. People come to believe crazy things all the time, and like the example I first mentioned, they falsely attributed two events to be connected, when in reality, they are not at all. But, if you believe in determinism (all events follow causally from the one before it), are you more likely to believe superstitions (two events are connected in a certain way)?
