Use a pre-commitment device to lock in hyperfocus sessions

Commit to a specific focus block in advance and introduce a friction cost to abandoning it.

Why it works

Pre-commitment exploits the temporal inconsistency between a present self that rationally values deep work and a future self that faces a specific moment of temptation to switch. By creating a commitment before the moment of temptation — scheduling the block, telling a colleague, using a site blocker — you bind the future self’s options when willpower is lowest. The friction cost of breaking the commitment changes the incentive calculation at the moment of temptation.

How to do it

1. Schedule your hyperfocus sessions in your calendar as fixed appointments — not "flexible time."
2. Tell one person (colleague, partner) what you are working on and when, so social accountability is active.
3. Activate a site or app blocker before the session starts, not when you feel tempted.
4. Treat breaking the block as a data point to analyze, not a moral failure — understand which trigger caused it.

Evidence

Pre-commitment (Schelling, Thaler & Sunstein) is well-supported across domains: research on commitment devices in health, savings, and productivity shows they reliably improve follow-through by constraining future options. (observational)

Pre-commitment research is robust; the specific hyperfocus application is a practitioner extension. The commitment device must be genuinely binding — a soft block that’s easy to override provides little benefit.

Common mistake

Using a site blocker but installing the override extension in the same browser session, making the commitment trivially breakable at the moment of temptation.
