As more women enter the managerial ranks, organizations are finding it necessary to address the possibility of gender bias in managerial performance ratings. To investigate the existence of gender bias in managerial performance ratings as they relate to problem-solving strategies, 197 college students (46 percent female) and 127 managers (of those who reported gender, 37 percent reported female), from a variety of organizational settings in Kansas, read a scenario describing a manager in a manufacturing organization who had a limited time to solve a production problem. Subjects subsequently rated the manager's performance according to promotion criteria and leadership characteristics. The scenario was manipulated for manager's sex, managerial or problem solving strategy, final outcome, and timing of the outcome. An analysis of the results showed that the students showed little evidence of gender bias in their responses; however, the female manager generally received slightly higher ratings on leadership characteristics than her male counterpart. The male managers did show gender bias, giving female managers low ratings following failure, but giving male managers equally high ratings for success or failure. (BL)
