Doing the same thing over and over, hoping to get different results.
I'm not a big fan of Skinner (the psychologist, not the DU GodHead). By all accounts he treated his children like he treated his pigeons and that wasn't very good.
There are a whole lotta people in the world who are literally trying to figure it out as they go along. Even on things as vital and important as the economy. Not everybody is curious. Not everybody enjoys (like I do) research and finding snips and bits and patching them all together in a big tinker-toy model of the Universe.
So these people, who keep doing the same random things, sometimes get rewarded and sometimes they don't. If the rewards are good enough, no matter how long they "dry" streak is, they will keep trying that same old trick, or some near variation, over and over hoping that
this time it will work. Just like the pigeons.
Unfortunately, some of these people work in the government, in the stock market (as your doctor, lawyer, etc.) And you can only hope that they hit upon a system that works more often than not.
Random Rules.
