Pygmalion Effect

Expectations can influence interactions and outcomes.

01 / UNDERSTAND

The idea

Expectations communicated through feedback, opportunities or interpersonal behaviour can affect performance in some settings. In research and training, take care that assumptions do not shape the help or evaluation someone receives.

Communicated expectations can influence confidence, effort and performance in some contexts. A learner told that mistakes prove inability may approach the next task differently from one given useful encouragement. Support improvement without inventing success or hiding accurate feedback. Clear, achievable guidance is more helpful than a guaranteed promise of ability.

02 / RECOGNISE

See it in real products.

Examples of how the principle can appear in an interface.

DuolingoEXAMPLE 01

Separate a mistake from a judgment of ability

Duolingo responds to repeated errors with encouragement that learning is still happening. The message frames the next attempt as worthwhile rather than treating the learner as incapable.

MimoEXAMPLE 02

Use an error as a teaching moment

Mimo introduces a relevant learning mechanic after an initial mistake. The response explains how to continue rather than ending with a negative evaluation alone.

03 / CONNECT

Why it matters.

Feedback can affect confidence and willingness to keep trying. Give specific, truthful encouragement without presenting an error as a permanent judgment of ability.

Possible influences to investigate, rather than guaranteed outcomes for every product.
