Is the Professor Bossy or Brilliant? Much Depends on Gender - NYTimes.com: Men are more likely to be described as a star, knowledgeable, awesome or the best professor. Women are more likely to be described as bossy, disorganized, helpful, annoying or as playing favorites. Nice or rude are also more often used to describe women than men.
Men and women seemed equally likely to be thought of as tough or easy, lazy, distracted or inspiring.
