Discussion at Inside Higher Ed.
Here is the discussion at the philosophy website Daily Nous (where the question is raised whether sexism is a myth...because only sexism against women can possibly be sexism; it's hilarious that in none of the linked to items above does the author raise the question about whether the study indicates that there is sexism against men, only whether there is not sexism against women. If the study would have been 2-1 in reverse, we'd be hearing about it endlessly. What we'll hear instead is how it was flawed or how it's not good evidence that the results apply to real world situations. Because we all know sexism against women is rampant.)
