"But as a Puerto Rican woman, she belonged to not one but two minority groups. New research suggests that her double minority status may have amplified the costs and the benefits of speaking up. Management researcher Ashleigh Rosette, who is African American, noticed that she was treated differently when she led assertively than were both white women and black men. Working with colleagues, she found that double minority group members faced double jeopardy. When black women failed, they were evaluated much more harshly than black men and white leaders of both sexes. They didn't fit the stereotype of leaders as black or as female, and they shouldered an unfair share of the blame for mistakes. For double minorities, Rosette's team pointed out, failure is not an option. Interestingly, though, Rosette and her colleagues found that when black women acted dominantly, they didn't face the same penalties as white women and black men. As double minorities, black women defy categories. Because people don't know which stereotypes to apply to them, they have greater flexibility to act "black" or "female" without violating stereotypes. But this only holds true when there's clear evidence of their competence. For minority-group members, it's particularly important to earn status before exercising power. By quietly advancing the agenda of putting intelligence online as part of her job, Carmen Medina was able to build up successes without attracting too much attention. "I was able to fly under the radar," she says. "Nobody really noticed what I was doing, and I was making headway by iterating to make us more of a publish-when-ready organization. It was almost like a backyard experiment. I pretty much proceeded unfettered." Once Medina had accumulated enough wins, she started speaking up again--and this time, people were ready to listen. Rosette has discovered that when women climb to the top and it's clear that they're in the driver's seat, people recognize that since they've overcome prejudice and double standards, they must be unusually motivated and talented. But what happens when voice falls on deaf ears?"
