Pygmalion Effect

A psychological phenomenon whereby broadcasting expectations for someone else, alters their performance.

Why it matters

For example, being told that you're good at something, can actually create a better performance.

But in the same vein, signalling to the user that they're bad at something, may have the reverse effect.

This is often called the Rosenthal effect.

Effort & motivation:

• If you're told that you're the best football player on the team, and people are relying on you, you may be more motivated, and put in more effort. • Likewise, if you're told that you have the ability to quickly learn to use a tool, you may be more motivated to then commit to learning how to use it.

Input quality:

• If the user is told that they're bad at something, then it can knock their confidence, and influence future results. • e.g., "you scored in the lowest 20% on Duolingo last month" could actually create a negative cycle, where your input quality was then worse as a result.

Common anti-patterns

  • Assuming users consciously notice every place where "A psychological phenomenon whereby broadcasting expectations for someone else, alters their performance" could apply.
  • Dense copy and parallel actions that increase mental effort unrelated to the user’s goal.
  • Ignoring downstream effects on effort & motivation when shipping this pattern.
