satisfaction. Consumers didn't know each other and were randomly assigned to
three groups: (1) receive a store brand of shampoo in a bottle clearly labeled as
such, (2) receive a premium brand of shamp00 in the premium brand's bottle, or (3)
receive a store brand of shampoo in the premium brand's bottle. Here are the
