When does tracking turn play into work?

Across six experiments, measurement increased output while draining enjoyment when attention shifted from the experience to the number.

Read the evidence

A flowing fabric ribbon travels farther as it passes through rigid metal gates, representing increased output alongside reduced freedom.

The walk becomes steps on a screen. The book becomes pages on a counter. The afternoon becomes a streak you are suddenly reluctant to break.

A number can make progress visible. It can also slip between you and the thing you were enjoying.

Across six experiments, people often walked or read more when their activity was measured—and enjoyed it less. The metric did not merely report the experience. It helped reshape it.

Six experiments put a counter inside leisure

Jordan Etkin studied 912 people as they walked, read and colored simple shapes. Some participants could see how much they were doing; others completed the same kind of activity without a visible measure. Additional conditions helped separate the act of measurement from the attention drawn to its output.

The studies asked two questions that dashboards often collapse into one: How much did people do? And how did doing it feel?

Those answers moved in opposite directions often enough to reveal a real trade-off. Measurement could increase production while weakening the pleasure that made someone choose the activity in the first place.

More pages, less pleasure

In one reading experiment with 310 participants, measured readers completed an average of 16.14 pages. Unmeasured readers completed 13.44.

If pages were the only outcome, the counter won.

Enjoyment told the other half of the story. Measured readers averaged 5.19 on the study’s scale, compared with 5.97 without measurement. The difference was statistically significant.

In a later reading experiment, the effect reached beyond a rating. After the assigned task ended, 27.3% of measured participants chose to continue reading, compared with 48.5% of unmeasured participants. The counter helped while it was present. Fewer people stayed once they were free to stop.

Experiment and outcome Measured Unmeasured
Experiment 4 · mean pages read 16.14 13.44
Experiment 4 · mean enjoyment rating 5.19 5.97
Experiment 6 · voluntarily continued reading 27.3% 48.5%

The rows use different units and experiments. Together they show the shape of the trade-off; they are not one combined effect size.

Why the counter changed the mood

The paper’s mechanism tests point to a familiar shift. Visible measurement made output more salient. Attention moved toward how much had been completed. An activity that had felt like leisure began to feel more like work, and intrinsic motivation fell.

No prize or punishment was necessary. A visible measure can supply its own pressure.

That does not make pressure useless. More output may be exactly what someone wants from a training plan, budget or rehabilitation program. Enjoyment is not the only outcome that matters. The mistake is treating the largest visible number as the whole benefit.

Not everything needs a live score

These were short experiments with selected, mostly low-stakes activities. Five used paid university students; one used paid US adults recruited online. They cannot tell us what years of wearable use will do, whether automatic background measurement feels the same or when accurate monitoring is important for health and safety.

They can sharpen the design question. Before showing a number, decide what job it should perform. Is it there to reveal a pattern, prompt a correction or document a result? Does it need to be visible during the activity, or would a later check be enough?

Some moments improve when feedback arrives. Others improve when the counter stays quiet.

The lifescore take

A number can help you move—and quietly change what moving feels like. In these experiments, visible measurement often raised output while lowering enjoyment. That makes tracking a design choice, not a neutral window. Decide what the number is for, when you need to see it and what deserves to remain uncounted. A useful metric serves the experience or the goal. It should not quietly become the goal.
