Why working alongside another human — physically or virtually — reliably helps people start,
sustain, and finish tasks.[1]
What is body doubling?
Body doubling is a behavioral technique where a person (the "doer") works on a task in the
presence of another person. Commonly used in ADHD management, it leverages social presence to boost initiation
and reduce distraction.[2][3]
How it works — core mechanisms
Social presence: Presence of others raises arousal, improving simple tasks (social
facilitation).[4]
Supportive accountability: Benevolent, expert human support enhances adherence.[5]
Social incentives: Fear of letting a partner down and reputational rewards nudge
follow-through.[6]
Behavior-change scaffolds: Goal setting, feedback, and monitoring are empirically
strong BCTs.[7]
Practical summary
People are more likely to start and persist with tasks when they expect to be seen and to
report outcomes.[2]
Evidence & real-world studies
Lab studies in social psychology, field experiments on buddy systems, and digital intervention
trials all confirm positive effects of accountability and co-working.[4][6] Importantly, effects vary: while some studies note boosts on simple or
routine tasks[4], others caution that complex or highly demanding work may not
benefit equally[5]. Likewise, personal differences matter — introverts or
highly anxious participants sometimes report discomfort in co-working situations[3].
Benefits of body doubling
Attention & initiation
Presence acts as a cue to start, reducing cognitive load of initiation.[2]
Reduced procrastination
Co-working sessions shorten time-to-task and maintain momentum.[6]
Accountability & adherence
Mutual accountability supports routine adoption and follow-through.[5]
Well-being & support
Body doubling reduces loneliness and validates effort.[3]
