With the threat of failure looming, students with the growth mindset set instead mobilized their resources for learning. They told us that they, too, sometimes felt overwhelmed, but their response was to dig in and do what it takes. They were like George Danzig. Who? George Danzig was a graduate student in math at Berkeley. One day, as usual, he rushed in late to his math class and quickly copied the two homework problems from the blackboard. When he later went to do them, he found them very difficult, and it took him several days of hard work to crack them open and solve them. They turned out not to be homework problems at all. They were two famous math problems that had never been solved.

A few modern philosophers … assert that an individual’s intelligence is a fixed quantity, a quantity which cannot be increased. We must protest and react against this brutal pessimism.… With practice, training, and above all, method, we manage to increase our attention, our memory, our judgment and literally to become more intelligent than we were before.

Are there situations where you get stupid — where you disengage your intelligence? Next time you’re in one of those situations, get yourself into a growth mindset — think about learning and improvement, not judgment — and hook it back up.

she believed that people’s IQ scores told the whole story of who they were. We were seated around the room in IQ order, and only the highest-IQ students could be trusted to carry the flag, clap the erasers, or take a note to the principal. Aside from the daily stomachaches she provoked with her judgmental stance, she was creating a mindset in which everyone in the class had one consuming goal — look smart, don’t look dumb. Who cared about or enjoyed learning when our whole being was at stake every time she gave us a test or called on us in class?

I’ve seen so many people with this one consuming goal of proving themselves — in the classroom, in their careers, and in their relationships. Every situation calls for a confirmation of their intelligence, personality, or character. Every situation is evaluated: Will I succeed or fail? Will I look smart or dumb? Will I be accepted or rejected? Will I feel like a winner or a loser?

Instead of just giving employees an award for the smartest idea or praise for a brilliant performance, they would get praise for taking initiative, for seeing a difficult task through, for struggling and learning something new, for being undaunted by a setback, or for being open to and acting on criticism.

Bloom concludes, “After forty years of intensive research on school learning in the United States as well as abroad, my major conclusion is: What any person in the world can learn, almost all persons can learn, if provided with the appropriate prior and current conditions of learning.
