One easy introduction to the power of direct eye contact is to take your kids down the cereal aisle at the grocery store and ask them which cereal looks the most appealing. A 2014 Cornell University study found, “Consumers are 16 percent more likely to trust a brand of cereal when the characters on the boxes on the supermarket shelves look them straight in the eye. Not surprisingly, the study also found that the gaze of characters on children’s cereal boxes is at a downward, 9.6-degree angle, while characters on adult cereal boxes look almost straight ahead.”

Aside from selling cereal, here are 8 more reasons to teach your kids the power of direct eye contact.
