You might not expect a study coming out of Brigham Young University's School of Family Life to have anything good to say about video games. And maybe this doesn't. But it says something a lot worse about books, and I'll take that as a win in this culture war.
Sarah Coyne, a social sciences researcher at the university (whose past work was mentioned here), found that teen-oriented novels contain twice the rate of cursing of most video games. Moreover, characters who curse are portrayed more admirably—as wealthier, better looking and more popular.
