We know that teams mixing people of different generations, genders, and cultures yield better outcomes, and that frank, constructive feedback is key to improving individual, group, and organizational performance. But these two attributes -- diversity and candor -- often clash, says Erin Meyer, a professor at INSEAD. She's studied the challenges that arise when teammates with different backgrounds try to give one another advice and offers recommendations for overcoming them, including establishing norms around regular feedback and ensuring that it is asked for, designed to assist, and actionable. She’s the author of the HBR article “When Diversity Meets Feedback.”
