Definition
A teachability index is the willingness to receive correction, log crash tests, and update the Manual without defending the old identity.
Origin
Dweck’s mindset research contrasts learning goals (update after error) with performance goals (protect image). Ericsson’s deliberate-practice frame requires feedback loops — teachability is the behavioural willingness to run them.
Mechanism
High teachability: correction lands as data. Low teachability: correction triggers identity defence and stops reps. Ericsson et al. note expert performance tracks accumulated deliberate practice — modest contrasting literature on innate-talent explanations; teachability is the personal gate on whether feedback becomes practice.
Applications
After a crash test or coach cue: one line — did I update the model or defend the story?
