Men who take the time to harass women they don't know online are losers.
It's something most people assume anyway, but now there's scientific proof. Researchers at the University of New South Wales and Miami University made the link after observing how men treated women over five months of playing Halo 3.
It was observed that men tended to be fairly polite to each other, no matter the skill level. Men who were good at the game were also more likely to compliment women.
However, men who were less-skilled at the game were "significantly more hostile" to their female counterparts, making far more sexist or negative comments.
"Our results support an evolutionary argument for why low-status, low-performing males are hostile towards female competitors," conclude study authors Michael Kasumovic and Jeffrey Kuznekoff.
"As men often rely on aggression to maintain their dominant social status, the increase in hostility towards a woman by lower-status males may be an attempt to disregard a female's performance and suppress her disturbance on the hierarchy to retain their social rank."
