How to utilise this in your designs

After users answer questions, you could show a notification that you're listening and learning, a gentle Hawthorne Effect cue that their input is being noticed.

UI with two white cards on purple background shows questions about anger and self-control techniques. Purple smiley icons bottom left with "LEARNING FROM YOU..." text.

Ahead

After a session, you could show an icon that users learn means their experience is getting more personalised, a recurring Hawthorne cue that their answers matter.

UI shows a progress bar, question "Did your focus or anxiety improve after last session?" with Yes/No teal buttons and a grey "Not sure" link; speech bubble notes personalized training.

Example from

Balance

Try anchoring each effort rating option to something obvious, like being able to talk, so Hawthorne-style exaggeration is less likely to skew self-reported answers.

Black UI panels show exercise intensity levels 1, 7, and 9 with white bold numbers and labels; underlined orange text emphasizes "walking slowly," "hard to talk," and "no talking."

Example from

Nike

You could make an exertion scale respond with colour changes, mascot animation and haptics, which may help answering feel less like being watched under the Hawthorne Effect.

Perceived Exertion UI shows mood icons for "Very Light" and "Very Hard" effort, colored exertion scale with "Above Usual Range" labels, and a "Did You Feel Differently?" Premium prompt.

Example from

Gentler Streak

You could offer a private sandbox to practise in during onboarding, so users can learn real features without the Hawthorne pressure of feeling watched or tested.

Superhuman UI shows a practice inbox welcome message with "Hit enter to continue" in lavender, an arrow points to a shared message by Miles on May 6 asking @Peter about contracts.

Possible impacts

Due to the Hawthorne Effect, observed users may read onboarding more carefully than usual, which could lead to overestimating real-world feature usage.

As seen in:

Balance Personalised learning

Nike Contextualising the effort

The Hawthorne Effect could cause a decrease in input quality, as users who feel watched may exaggerate their feelings, e.g., claiming they'd pay, then never doing so.
