p- in a classic experiment by b.f. skinner, pigeons were given food automatically every 15 seconds. the birds did not have to do anything for the food to appear, but clearly the birds thought otherwise. for example, if a bird had one leg raised when the food first appeared, it might keep lifting the same foot to test to see if that was the way to get more food. sure enough, a few more seconds pass and food arrives, reinforcing this behavior. after awhile the bird is hopping around all the time on one leg. other birds developed different superstitious behaviours like bobbing, twirling and pecking. ... just like people, no? bird brain
