Here’s a study I wish I had done: a new study in the journal of Social Psychological & Personality Science reports that consumers believe that chocolate labeled as Fair Trade has fewer calories than non-Fair Trade chocolate.
This is an example of the halo effect, in which one positive trait bleeds over and influences perceptions of other traits. Remember, Fair Trade chocolate is better for its workers but not any healthier for your body!
