How to utilise this in your designs

After three wrong answers in a row, you could reassure users they're still making progress, offsetting the negative Pygmalion Effect of a poor evaluation.

Example from

Duolingo

When users get too many answers right in a row, you could automatically raise the difficulty, which may act as a subtle Pygmalion signal that you expect more.

Example from

Duolingo

You could frame game scores relative to other players, wording it carefully so the comparison broadcasts high expectations, not that users are below par.

You could notify users when a friend has a perfect month. Knowing friends will see their achievements too may set Pygmalion-style expectations that lift effort.

Example from

Duolingo

After a user completes a custom goal, you could tailor the celebration to that specific task, reinforcing the expectation that they can hit the next one too.

Avoiding negative evaluations, e.g., 'lowest 20%', might prevent a Pygmalion-driven knock to confidence, helping users avoid a decline in the quality of future inputs.
