Is Superstition Rational?
Friday, May 9th, 2008Just because we’re superstitious doesn’t make it rational, or does it?
It’s been a wet week here in New York. On days when it might rain, I like to take along an umbrella to reduce, I hope, the chance that it will rain on me. This week I took an umbrella and still it rained. It hasn’t shaken my faith in my superstition.
John Tierney’s “Why Superstition Is Logical” makes a muddled and perhaps incomplete attempt at explaining the rationality of superstition. He begins with the example of a rational person irrationally resisting the temptation to set her watch to the correct time zone until the plane lands. He then discusses some circumstances in which superstition induces a positive psychological boost to “do the right thing.” To wit:
1. Students think that not doing their reading makes them more likely to be called on in class… so they do the reading.
2. People think that trading away a lottery ticket makes that ticket more likely to win… so they hold onto the ticket… obviously with much more of an upside potential than a trade.
3. An applicant to Stanford graduate school is less likely to get in if he goes around wearing a Stanford T-shirt… he may or may not get in, but he’s less likely to look like a jerk.
I couldn’t quite figure out how not having set one’s watch before an airplane disaster fell into the same category as these examples.
Interspersing these sets of seemingly divergent examples, Tierney inserted yet another intriguing piece of data related to superstition. He mentioned that negative outcomes have a subliminal tug. We recall the day we got caught in the rain much more readily and with much more emotion than we recall the days when we didn’t get caught in the rain. This leads us to believe that getting caught in the rain is the more likely outcome.
To all of which I have a couple of thoughts to add.
Let’s say that there’s a 50/50 chance that we’ll get rained on when we think we might get rained on. And let’s say that if we’re neither overly optimistic nor pessimistic we’ll sometimes take precautions against the chance of getting rained on and sometimes not. Naturally, if it looks like rain our precautions might include avoiding going outside, or taking the car instead of walking. On the remaining days, when we stick to our plan of going out and walking not driving, we’ve therefore, without superstition, increased the likelihood that we will get caught in the rain.
Here’s how that works:
Start with ten days. Five will be rainy, five won’t. Five days we’ll be optimistic and risk the rain. Five days we’ll be pessimistic and won’t risk the rain. Of the five pessimistic days, we’ll stay in one day, drive another day, leaving three days that we’ll carry an umbrella. This means that out of ten days, we avoid the risk of rain entirely on two days, (on average one of these will be rainy). This leaves eight days, four of them rainy four of them not rainy. But we’ll have our umbrella with us on just three of those days…
Even to get to an even chance, we need a little superstition.
Now to the other thought.
We recall negative outcomes for an evolutionary reason. They are learning experiences, cautions. All animals have evolved with this feedback mechanism. Or, perhaps more precisely, those that didn’t have died.

My four year-old son gloms on to new interests with great intensity and with a level of focus that seems infinitely unflagging. Depending on the interest, his mother and I either rejoice (relatively speaking) at his fascinations, or despair. But neither state lasts long. Just when we think he’ll be a Thomas The Tank Engine junky all his life (despair!), he moves on to Lightning McQueen (better). And as we begin to worry that he’s reciting all the words to the Cars movie, he drops that and moves on superheroes. Now we’re anxiously awaiting the next new thing while we try to figure out how to dissuade him from wearing his superhero costumes — complete with capes and masks — everywhere he goes.
NPR reports on James Lee Woodward, the 17th Dallas man to be exonerated by DNA evidence. Woodward had spent 27 years behind bars, even forgoing chances of parole because he wouldn’t apologize for a crime he didn’t commit. The new Dallas DA — Craig Watkins — is determined to reexamine as many dubious convictions as possible in order to get the innocent out from behind bars
Institutions, after all, comprise people, people doing what they’re accustomed to doing, and what they are told to do, or implicitly or explicitly encouraged to do. It is the Craig Watkins of the world who act as catalysts for change within our institutions. (Sadly Watkins success at overturning old convictions with DNA evidence can’t be replicated in other parts of Texas — everywhere else the DNA evidence of these old cases has been discarded.)
We tend to regard stress as something inherently bad. Doctors worry about it in their patients. Spouses worry about it in their spouses. Employers sometimes worry about it in their employees. But, as with most things, I would expect that some degree of stress every now and then may not be a bad thing. If we were to react to risky or troublesome situations without any stress, would we respond appropriately?
This brings us to the point that some stress remedies are personal — regular exercise, working to a reasonable household budget, taking time for onesself — and some are societal. The cost of private education seems to be a case in point. Generally speaking, the cost of private education has been going up so dramatically that it looms large in people’s minds for years before a child goes off to college, and then looms large for many years afterward as the debt hangs over them.
After two years of study the
As I consider the power of the imagination alongside the power of rational or logical processing I realize that the kind of thinking we do to survive combines these two elements. Thinking entails imagining scenarios or possibilities and calculating or predicting outcomes.

Herr Klein’s target, though, at which he takes aim in somewhat rhetorical mode after leaving his research data behind, is the time stress we put ourselves under these days. One can’t dispute that Klein speaks the truth when he says that “Our society is obsessed as never before with making every single minute count. ” But what, may one ask, are we to do about it?
(As a relevant tangent, my friend, a university lecturer, told me that his students comlpained recently when he asked them to watch an educational program during the evening because the program went head to head with Deal or No Deal…)

Whereas, the proliferation of parking permits (enough to fill many city blocks with “official” vehicles) seems to call loudly and rightly for greater constraint. Here again, though, the concept of constraint can be looked at from two perspectives. If I were a city employee I would probably enjoy having a parking permit. And, if I felt I needed the permit in order to do a better job for the city, I might not like the idea that someone may deny me a permit. But, as a member of the public, I would like to believe that vehicles get issued with a permit for legitimate reasons. After all, I’m subject to parking regulations, tariffs and fines, why should a regular city employee not be?
