How to utilise this in your designs

After a user gets three answers wrong in a row, you could reassure them they're still making progress, offsetting a negative Pygmalion Effect before confidence drops.

Example from

Duolingo

You could experiment with pausing a lesson mid-streak to say how great they're doing, broadcasting high expectations that may lift effort for the rest.

Example from

Duolingo

Try reframing a user's first mistake as part of learning, so the Pygmalion Effect works in your favour, then use that moment to introduce a new mechanic.

You could match users against similarly skilled peers so the promotion zone always feels within reach, signalling an expectation of success that may lift effort.

Duolingo app leaderboard UI shows "You unlocked Leaderboards!" tooltip. Promotion Zone highlights ranks, XP, and user avatars, with Peter Ramsey at rank 23 with 29 XP.

Duolingo

When showing game scores, you could frame performance relative to others, so the comparison signals capability rather than broadcasting low expectations.

Dark-mode UI with orange bar showing "Average solving time 5.84 seconds" beating 96% users; green performance insights show score 802 beating 3%, rank Beginner to Novice.

Possible impacts

Broadcasting positive expectations, e.g., telling users they'll master a tool quickly, could increase their motivation and the effort they commit, via the Pygmalion Effect.

Avoiding signals that users are performing badly, e.g., low percentile scores, might prevent a drop in the quality of their input caused by a negative Pygmalion cycle.
