Growth mindset
// What the research shows
Sisk et al. (2018) tested this in two meta-analyses: the link between growth mindset and academic achievement was weak, and interventions meant to instil a growth mindset had only very small effects overall. Students from disadvantaged backgrounds benefited somewhat more.
// In practice
- The core idea holds in training anyway: strength and technique are trainable, as every study here shows.
- But don't expect miracles from a “mindset switch” alone. What counts is what you then actually do.
- Use setbacks as information, not as a verdict on yourself.
// Limitations & open questions
The research comes almost entirely from education. There's hardly any direct data for sport and training.

Goals & if-then plans
“If X happens, then I'll do Y” demonstrably helps you follow through. The effect is smaller than early numbers suggested, though.
Building habits
The “21 days” is a myth. In the best-known study it took 66 days on average, with a huge range. Missing one day doesn't break it.
Self-talk
Deliberate self-talk moderately improves sports performance, especially when practised beforehand.
Mental training & visualisation
Vividly imagining movements does make you somewhat stronger. It doesn't replace real training, though.
