Automatic, unconscious self-control
The results showed that, when participants were thinking concretely, they tended to unconsciously see candy bars in a positive light and apples in a negative light. But this was reversed when participants were thinking abstractly. Just as predicted, abstract thinking automatically made people unconsciously think of candy bars as the devil’s own food.
To back this up they asked participants in the two conditions whether they would like an apple or a candy bar, right now. They found that when participants were thinking in a concrete low-level way, they chose the apple over the candy bar only 50% of the time. But when they were thinking abstractly this percentage shot up to 76%. Not bad for such a simple manipulation.
