Mindset

Dweck distinguishes a fixed mindset, in which a person believes intelligence and ability are static traits, from a growth mindset, in which they believe ability develops through effort and strategy. She argues that the belief itself changes behaviour, because people holding a fixed view avoid challenges that might reveal limits, treat effort as evidence of low ability, and respond to setbacks by withdrawing.

The research base is decades of experiments with schoolchildren, most famously the praise studies. Children praised for intelligence after solving problems subsequently chose easier tasks, performed worse after difficulty and were more likely to misreport their scores. Children praised for effort chose harder tasks and improved. Dweck extends the framework to sport, business, relationships and parenting, using cases including Enron as an organisation that recruited and rewarded fixed-mindset talent.

The practical content concerns praise and feedback. Dweck argues that praising process, strategy and effort produces different behaviour than praising ability, and that organisations should be examined for which they reward. She also describes the false growth mindset, where people claim the label while behaving as before, and she has spent years correcting the reading that growth mindset means praising effort regardless of result.

The replication record is mixed and this matters. Large pre-registered studies and meta-analyses find effects far smaller than the early work suggested, often near zero for academic achievement, with possible small effects for low-achieving students. Some researchers argue the construct does not hold up outside Dweck's own lab. The praise findings have replicated better than the intervention findings. Treat the distinction as a useful frame for feedback and treat the claimed effect sizes with caution.
