But according to a new study, sleeping on it can help us avoid judging a book solely by its cover. In research published Sept.

In a series of experiments conducted online, the researchers asked participants to look through virtual boxes of unwanted goods for items to include in the sale. Most of the items inside each box weren't worth much—an old alarm clock, for example, or a potted plant.
