How Do you Make a Well or a Ram Disappear? By Rabbi Rob Scheinberg Twenty years ago, two experimental psychologists at Harvard, named Christopher Chabris and Daniel Simons, created what has become one of the most famous experiments in the behavioral sciences. The participants in this study were given a simple task. They just had to watch a brief video that included several people passing basketballs back and forth to each other. Three of these players were wearing white shirts, and three were wearing black shirts. The task was simple: watch the ball that was being passed among the players with the white shirts, and count how many times the basketball was passed. This is not difficult – most people came up with the right number.
