Body doubling: popular, plausible and barely studied

Body doubling means doing a task while someone else is present, in the room or on a call, usually working on something of their own. Many people with ADHD say it helps them start and keep going. The first academic study of it, a survey of 220 people, opens by noting that the practice had not been studied at all ¹.

What the evidence says

In that survey, most participants said they had used the technique long before learning its name ¹. In its results, as quoted in a later paper, “someone in the room” came up far more often than a call or chat, with 127 mentions against 27 ².

The closest established research is on “social facilitation”, the effect of other people’s presence on performance. A meta-analysis of 82 studies of physical movement tasks, spanning a century and published as a preprint that has not been peer reviewed, found that having others present generally helped with fitness-type tasks, while results were mixed for tasks needing coordination under time or precision pressure ³. It did not look at desk work. Who is present matters too: one meta-analysis found people ate more with friends but not with strangers ⁴.

A related finding is about keeping track. Across 138 experiments, monitoring your own progress improved goal attainment, and more so when the results were reported to someone or written down ⁵.

What we don’t know

Whether body doubling improves what people actually get done is not settled. A 2024 master’s thesis that tested it with ADHD participants is cited as finding no significant effect ⁶. In a virtual-reality bricklaying experiment with 12 adults with ADHD, published as a preprint that has not been peer reviewed, people worked faster with a human or an AI partner than alone ⁷, but their own ratings of how efficient they had been did not differ significantly between conditions ⁸.

There are also costs. In that experiment one participant said the human presence felt “a little awkward” and the AI was “a lot less pressure” ⁹. A study of ADHD students’ posts described camera requirements as providing accountability and being a barrier at the same time ¹⁰, and one community moderator observed that for some people the benefit may be driven by guilt, shame or anxiety ¹¹.

Things to try

• A room with other people in it is the form people mention most ². A library or café costs nothing to test.
• “Study with me” videos. A study of these videos found that viewers used them for atmosphere, a kind of peer pressure they could control, and emotional support ¹². One viewer said that when they felt like stopping, the person on screen was still studying, so they kept going for longer ¹³.
• Be careful with close friends. One participant in the same study said studying with a close friend meant feeling obliged to talk and getting little done ¹⁴.
• Notice how it feels. If it only works by making you anxious about being watched, that is worth knowing.
