Irrational thinking springs up everywhere. Some irrational beliefs are passed on to us. But others we find on our own. Survival requires recognizing patterns - night follows day, berries of a particular colour that will make you ill. And because missing the obvious often hurts more than seeing the imaginary, our skills at inferring connections are overtuned. We look for patterns because we hate surprises and because we love being in control. In the real world, meaningful coincidences often incite unfounded suspicion about a mystical tinkerer behind the scenes.
And yet... It feels like there should be more to it.
[Side note: Notice, I said feels. I've noticed that when I am talking about a concept/theory or idea which is rooted in logic, then I would tend to say "I think", but if I am on 'fluffier' ground, I tend to go with "I feel". Why?]
"There are many layers of belief," psychologist Carol Nemeroff says. "And the answer for many people, especially with regard to magic, is, 'Most of me doesn't believe but some of me does.'" People will often acknowledge their gut reaction and say it makes no sense to act on it - but do it anyway. Other times, they'll incorporate superstition into their worldview alongside other explanations. This is something I am aware that I do - even though it is highly irrational. Seeing causality in coincidence can happen even before we have a chance to think about it; the misfiring is sometimes perceptual rather than rational.
Wishing is probably the most ubiquitous kind of magical spell around, the unreasonable expectation that your thoughts have force and energy to act on the world. Who has not resisted certain thoughts for fear of jinxing oneself? Made a wish while blowing out birthday candles? Who are we to say the dreamers have it wrong?
