Things That Can Make You Less Attractive, According To Science

Not having a sense of humour
A guy walks into a bar … fumbles a joke and leaves alone. A 2009 study from researchers at the University of California, San Diego found that not being funny — and even having just an average sense of humour — is less attractive than having a great sense of humour. The study also found that gender didn't play a role — a poor sense of humour was equally unattractive in men and women.
