Seeing What Seems Not To Be There: Thoughts for Pessah
I recently read of a phenomenon known as “inattention blindness.” When people are focused on a particular thing, they tend not to see anything that interferes with their concentration. For example, psychologists asked a group of people to watch a film of a basketball game and to count how many times team members passed the ball to each other. While the people were engaged in viewing the basketball game and concentrating on their assignment, the tape showed a person walking right through the center of the picture in a way that would obviously be noticed.
