When there are images of eyes around, people are less likely to steal and more likely to donate money. What about images of other body parts? Moreover, do images of eyes make dogs less likely to steal as well? What measurement on the body is correlated with success at your job and athletic prowess in sports? In this episode, Lu and Tirth take an obscure anatomy terminology quiz, discuss how images of eyes, mouths, and noses affect pro- and antisocial behavior in people and in dogs, and dissect whether the size of a part of your body may predict success in life.
