Paul Thomas considers some of the research verities that have recently been exploded, like “the marshmallow test,” “growth mindset,” and “the word gap.”

He might have added “grit” to the list of recently debunked nostrums. Christine Yeh of the University of San Francisco wrote a terrific piece in Education Week last year titled “Forget Grit.
