by examining the neurophysiological profile of these students, Berka was able to identify “emergent leaders”—those individuals who would have an outsize positive impact on the team and its decision making—in as little as thirty minutes. While there was no correlation between emergent leadership and how much students talked or even what they said, there was a direct relationship between their neurophysiological responses and those of their classmates. Transformational leaders not only regulated their own nervous systems better than most; they also regulated other people’s.
