Inattentional blindness
В это трудно поверить, пока не убедишься лично. В фильме ВВС я увидел гориллу в экспериментальном ролике (см. ниже) - возможно, поскольку был внутренне готов к необычному. Но я абсолютно не заметил ее неоднократные появления на задних планах в других эпизодах фильма.


SciAm: None So Blind (2004)
Picture yourself watching a one-minute video of two teams of three players each. One team wears white shirts and the other black shirts, and the members move around one another in a small room tossing two basketballs. Your task is to count the number of passes made by the white team--not easy given the weaving movement of the players. Unexpectedly, after 35 seconds a gorilla enters the room, walks directly through the farrago of bodies, thumps his chest and, nine seconds later, exits. Would you see the gorilla?
Most of us believe we would. In fact, 50 percent of subjects in this remarkable experiment by Daniel J. Simons of the University of Illinois and Christopher F. Chabris of Harvard University did not see the gorilla, even when asked if they noticed anything unusual. The effect is called inattentional blindness.

Without realizing it, people will perceive things according to how they want to see them, a new study suggests.
