I was curious about this claim "... that any coverage of a woman’s appearance, even flattering coverage, diminishes voter perception of her competence. " So I skimmed the linked oxford academy article. I can't see where it supports this exactly l, although it does match my intuition... Did they also compare perceived competency of men that receive relatively more commentary on their appearance? It also occurs to me that one reason a person, regardless of gender, may have a higher ratio of commentary on their appearance rather than policy, is because they are in fact less competent, giving the media less meaningful content to discuss. Just to be clear, I'm not dismissing the discrimination women face daily or stating a conclusion, I just didn't see where it was proven here.
