To Bem’s surprise, both groups increased their consumption of brown bread, and by a similar amount, the following week. “Somehow my saying to them, ‘You like brown bread’ was the same as their saying it to themselves,” he explains. “The leap I made from that is, maybe as adults we rely more on observations and inference from stimuli and our own responses to decide what our internal states are.” An example would be eating a second sandwich and then remarking to yourself, “I guess I was hungrier than I thought,” or realizing only after biting your nails all day that “something must be bugging me.”
