Things That Can Make You Less Attractive, According To Science

Laziness
The results of a series of experiments, published by researchers at the University of Wisconsin-Madison and the State University of New York at Binghamton in 2004, found that perceived attractiveness can be correlated with traits like helpfulness. In one experiment, researchers asked students in a six-week archaeology course to rate each other on different personality traits, as well as attractiveness. They did so at the start and end of the course. When researchers analysed the results, they found that even students who'd been rated average at the beginning of the course were rated less attractive than average later on if their classmates saw them as lazy (for example, uncooperative and not hard working).
