Explanation: Harvard psychologist Mahzarin Banaji offers this test in lectures to show how easily a false memory can be created. Most people remember seeing the word "insect" in the first list. The mistake happens because the words in the first box were associated with insects: Unlike a machine, human memory is prone to error, because of reasonable-but incorrect-assumptions. "Mind bugs operate without us being concious of them," Banaji says.
