Anyone who follows my blog or has read my book, Belief in Science and the Science of Belief, well knows that I argue passionately against most forms of belief-based thinking. But I do have to admit that sometimes a teeny tiny bit of false belief is helpful.

I rarely ever steal anything. If I realize that I was given too much change at the market, I’ll invariably drive back to return it. I don’t do the right thing because I’m such a noble upstanding person. I do it because of superstition.

You see somewhere I picked up this deeply ingrained notion that if I keep that money, the universe will somehow take revenge on me. I’ll stub my toe, or get a traffic citation, or spill coffee on my term paper. In some way I’ll pay tenfold for my dishonesty.

Of course that’s silly. I know that’s silly. Something bad will happen eventually, and when it does I will falsely ascribe the cause to be my earlier bad behavior. But nevertheless, the feeling of wanting to avoid this bad karma is so powerful that it still compels me to do the right thing.

Perhaps this belief in karma is just something learned from popular culture, but I rather suspect that our species carries the hardwired seed of this idea which gets reinforced by false associations acquired during ones lifetime. It makes evolutionary sense to me that such an assumption is a helpful genetic trait. Within social structures, what goes around does in fact often come back around.

Our innate fear of karmic payback is almost certainly a component of what we perceive as our nagging conscience.

Here’s the danger in this. It leads many people down the rabbit hole into religion-land. If we believe in a little auto-karma, why not an almighty god who personally ensures payback? If a little karmic fear is good, then the fear of eternal damnation is even better. If our sense of personal karma is hardwired, then so is our belief in god!

But one essential principle you learn in toxicology class is that everything that is beneficial at low doses becomes toxic at higher doses. A little superstition may have some positive benefits. But a full-blown belief in god requires a level of superstition and a perversion of logical thinking that is so extreme as to be dangerously toxic. This level of belief is so debilitating to our logical faculties that it can compromise our ability to think rationally about critical issues like climate change.

So feel free to embrace a healthy sense of karma like you do a magic show, with a full and complete understanding that it’s not real. But don’t let that indulgence lead you down the treacherously slippery slope into religion.
