Why That Cute Girl At the Bar Isn’t Smiling At You

We’ve all been in that situation where you’re blissfully engrossed in a new subway advertisement and you suddenly notice the crazy person in the corner seems to be smiling at you. But you’re not sure. Maybe they’re merely pleased by the informative contraception PSA to your left. The bad news is that there’s no magical trick to figure out where they’re looking, and the really bad news is that research shows whatever you do think is likely to be biased by the person’s facial expression. Specifically, we tend to think smiling faces are looking at us and angry faces are looking away from us.
Fifty-two observers judged where faces were looking by moving a slider on a measuring bar to the respective position. The faces displayed either an angry, happy, fearful or a neutral expression and were looking either straight at the observer, or were rotated 2°, 4°, 6° or 8° to the left and right. We found that happy faces were interpreted as directed closer to the observer, while fearful and angry faces were interpreted as directed further away. Judgments were most accurate for neutral faces, followed by happy, angry and fearful faces. These findings are discussed on the background of the “self-referential positivity bias”, suggesting that happy faces are preferably interpreted as directed towards the self while negative emotions are interpreted as directed further away.
On the bright side, if you notice a cute girl in a bar and she looks like she wants to punch somebody in your direction, you can be fairly confident it’s you.
I think it would be interesting to know what mechanisms are driving these biased interpretations of gaze directions. From an evolutionary standpoint, it makes sense that we would think happy faces are directed toward us. Having such a bias would increase interactions with potential mates and lead to a higher chance of procreation.
What makes less sense is the tendency to think angry faces are directed away from us. Protecting yourself from danger is nearly as crucial as mating, and therefore it would seem adaptive to overestimate the number of angry faces looking in your direction. If that big Neanderthal from the other tribe seems to be scowling at you, you should probably just assume he is and get the hell out of there. My guess would be that the tendency to think angry faces aren’t directed toward us is a result of more recently evolved emotional management skills. In the long run you’ll probably be happier if you assume all the fearful and angry faces you see have nothing to do with you.
