(Poets&Quants) -- A year ago, Robert Bruner found himself in a discomforting place -- at the end of a wagging finger and a hard-hitting question. The dean of the University of Virginia's Darden School of Business was in Shanghai at a reception for potential applicants to the school's prestigious MBA program when a young Chinese woman stood. "Why don't you admit more Chinese?" she asked sharply. The room fell to a hush, waiting for Bruner's answer. He pointed out that China already was the most highly represented nation among Darden's international students. To admit far more students from a single country, he argued, would likely mean that Darden would offer less diversity in any given class and accept applicants who weren't as qualified to attend its highly selective MBA program. "Why would you go half way around the world to study with people exactly like you?" asked Bruner. "The point is to get out of your zone of comfort and stretch yourself against the very best talent in the world." The prospective applicant nodded and smiled. The point was made, and Bruner moved on to a softball question more typical in such settings.
