The Popcorn Eating Habit

People who said they ate popcorn all the time at the movies ate the same amount of stale popcorn as fresh popcorn, didn't matter which bag they were given. The habit of eating popcorn was so powerful that it really didn't matter what it tasted like. If you were used to doing it, you just kept on doing it. We had another version of the experiment in which we had participants hold the bag of popcorn with their dominant hand. And when there was that little bit of friction on eating, even people with strong habits to eat pop corn, in the movie cinnema, they didn't eat the stale popcorn any more.
