Rather than praising him for being smart, they should have praised him for working hard. On the successful completion of a test, they should not have said, “I’m so proud of you. You’re such a bright kid.” That appeals to a fixed, uncontrollable intellectual trait. It’s called “fixed mindset” praise. His parents should have said, “I’m so proud of you. You must have studied a lot.” This appeals to controllable effort. It’s called “growth mindset” praise.
