Great article, Amey! The "fragility" of students you mention comes from their teachers stressing a fixed mindset rather than a growth mindset. You "are" smart, successful, etc. So failure destroys their entire self-image. If teachers stressed process - you did so well, you must have studied very hard - when they experience failure, they look at it as a failure of process, and because they're so talented, they can find the flaw and fix the process.
