Lingering superstitions?

[Angrboda]

I have "spells" where I become superstitious or religious for a while, and then just as suddenly get over it. I'm deeply religious if that counts, though I wouldn't put that in the same league.

I think of superstitions as primarily the result of an episode of faulty learning, so anyone can pick up a superstition at any time, as it's only partially a function of personality traits like skepticism, religiosity, and credulity. This is probably why superstitions are such a prominent part of sports. Athletes are constantly trying to learn, so more faulty episodes of learning will occur, with stronger motivation to maintain it.

I have the feeling my "spells" are caused by something neurological, but I think it's perfectly natural for ordinary, mentally healthy people to have similar spells of lesser intensity. Skepticism seems to be the norm for me.
