Here’s looking at you
According to a study published by the University of Aberdeen in 2008, attraction isn’t just based on looks, but also “social cues” – i.e., someone’s effort to show that they like the person. This can be communicated in various ways (including simply telling them!), but the study highlighted a simple enough technique – looking straight at the person you’re into and flashing a smile. “What we found was that the preference for [a] face was much stronger when people were looking at them and smiling,” said psychologist Dr Ben Jones, one of the authors of the study.
