Many of us have had the experience of listening to a talk and suddenly making a connection between the speaker’s big idea and a challenge we face at work. To listen to David Rock, of the NeuroLeadership Institute, for example, is to have one’s eyes opened to recent neuroscience research. One discovery Rock shares is that when people realize they are being compared with others, a “threat response” in their brains sends cortisol levels skyrocketing and makes it hard for them to take in other information. If you oversee your company’s annual performance review process and it centers on the delivery of a single number derived from a stack-ranking exercise, this insight could be a lightbulb going on.
