A new study shows that we sit next to people who physically resemble ourselves.
"Across four studies, people sat (or reported they would sit) closer to physically similar others," the researchers wrote in the paper's abstract. "Study 1 revealed significant aggregation in seating patterns on two easily observed characteristics: glasses wearing and sex. Study 2 replicated this finding with a wider variety of physical traits: race, sex, glasses wearing, hair length and hair color."
Overall, people had a tendency to sit next to others that were similar physically, even when factors for sex and race were controlled. This suggests that people are drawn to physicality than social categories.
"Study 3 conceptually replicated these results in a laboratory setting. The more physically similar participants were to a confederate, the closer they sat before an anticipated interaction when controlling for sex, race and attractiveness similarity," the researchers wrote. "In Study 4, overall physical similarity and glasses wearing similarity predicted self-reported seating distance. These effects were mediated by perceived attitudinal similarity."
Go ahead, look around and notice who you're sitting next to at an event you attend. Chances are, those people will look like you.
