In The Psychology of Interpersonal Relations, Heider argued that social perception follows many of the same rules of physical object perception, and that the organization found in object perception is also found in social perception. Because biases in object perception sometimes lead to errors (e.g., optical illusions), one might expect to find that biases in social perception likewise lead to errors (e.g., underestimating the role social factors and overestimating the effect of personality and attitudes on behavior).
