Statistics like class rank and performance-review grades are meant to compare us to the average person. This hour, as part of KERA’s American Graduate initiative, we’ll talk about why these comparisons are essentially meaningless – and about the value in identifying how we’re different from those around us – with Todd Rose, director of the Mind, Brain, and Education Program at the Harvard Graduate School of Education. He’s the author of “The End of Average: How We Succeed in a World That Values Sameness” (HarperOne).
