Growth and fixed mindsets are better defined as responses to feedback, particularly feedback on errors, shortcomings, and setbacks, than as beliefs about intelligence. As reported in, “Seeing the benefits of failure shapes kids’ beliefs about intelligence“:
Parents who tended to view failure as a negative, harmful event had children who were more likely to believe that intelligence is fixed.
…parents who adopted a more negative stance toward failure were more likely to react to their child’s hypothetical failing grade with concerns about their child’s lack of ability. At the same time, these parents were less likely to show support for the child’s learning and improvement. Their reactions to the failing grade were not linked, however, with their beliefs about intelligence.
Actions speak louder than words, especially self-reported words that conform to social desirability.
