“From the vantage point of the brain, doing well in school and at work involves one and the same state, the brain’s sweet spot for performance. The biology of anxiety casts us out of that zone for excellence. “Banish fear” was a slogan of the late quality-control guru W. Edwards Deming. He saw that fear froze a workplace: workers were reluctant to speak up, to share new ideas, or to coordinate well, let alone to improve the quality of their output. The same slogan applies to the classroom—fear frazzles the mind, disrupting learning.”
