Looking, listening, peeking, eavesdropping, fingering, shaking, and grasping are all actions that give us energy at the receptors, but by themselves do not ultimately specify a particular object. Many different objects could have produced those same sensations. Handel argues that all senses make use of the same principles and physiological processes to split the sensations into the part that yields information about real objects and the part that yields information about the non-predictable parts of the background. The real objects undergo predictable transformations and the interacting local to global physiological organizations are tuned to pick those up in spite of sensory or cognitive limitations. Summing up, Handel compares the myths about business decision-making to perceptual decision-making.
