abstract:The gaze heuristic is a heuristic employed by people when trying to catch a ball. Experimental studies have shown that people do not act as though they were solving a system of differential equations that describe the forces acting on the ball while it is in the air and then run to the place at which the ball is predicted to hit the ground.
When Jeffrey Skiles, the co-pilot of the plane that made an emergency landing in the Hudson River in January 2009, explained how he and his captain decided that an airport landing was impossible, he described the same "gaze heuristic": The angle of the plane's descending glide made the airport appear to rise in their windscreen view clearly signaling that a landing there was doomed.
