The Evening Accountability Check-In is a brief conversation that closes the current day and pre-commits the next one. Start by reviewing whether defined input goals, such as hours of focused work, and output goals, such as drafted sections, were met. Add behavior and health signals that affect performance, including caffeine, exercise, pain, or migraines. Then set realistic input and output targets for the following day. The accountability partner supplies friendly pushiness while challenging plans to compensate for a weak day with an exhausting marathon. This creates a recurring feedback loop: commitments make avoidance socially costly, measurement reveals actual capacity, and supportive correction prevents shame from turning one poor day into several. MacAskill estimated that ten-minute check-ins increased his productivity substantially while writing his book.

Origin

Will MacAskill used evening check-ins with his employee Laura while writing What We Owe the Future during the pandemic.

Core principles

  • 01Measure both effort and completed output
  • 02Make tomorrow's commitments before the day begins
  • 03Use accountability without punishment
  • 04Protect sustainable performance from compensatory overwork

How to run it

  1. 1

    Define measurable commitments

    Set an input target for focused effort and an output target for completed work. Add only the behavior or health measures that materially affect performance.

    Pro tip Separate time spent from deliverables completed so neither can hide the other.

    Watch out Vague goals make the review subjective and easy to evade.

  2. 2

    Review the day

    At the agreed time, report how each commitment turned out. Include relevant constraints such as pain, migraines, exercise, or excess caffeine without converting the review into self-punishment.

    Pro tip Keep the meeting to roughly ten minutes.

    Watch out Shame can trigger unrealistic attempts to recover all missed work at once.

  3. 3

    Set tomorrow's targets

    Choose the next day's input and output commitments using evidence from prior days. Make them demanding enough to matter but sustainable enough to repeat.

    Pro tip Use tracked experience to challenge heroic plans that usually produce little extra work.

    Watch out Do not turn a disappointing day into a twelve-hour day or an all-nighter.

  4. 4

    Apply friendly pushiness

    Have the accountability partner combine encouragement with enough pressure to make the commitment real. Adjust the tone to the relationship and the worker's failure mode.

    Pro tip Choose someone who knows when to push and when to restrain you.

    Watch out The wrong interpersonal fit can make accountability either toothless or harmful.

In the wild

Finishing a difficult book

MacAskill reported focused-work hours, drafted sections, caffeine, exercise, migraines, and back pain to Laura. They then agreed the next day's targets. Knowing that he would need to report back made it harder to abandon an entire day, while Laura challenged plans to work through the night after disappointing progress.

He estimated that the ten-minute daily check-ins increased his productivity by roughly 20% to 25%.

Common mistakes

Using accountability as punishment

A harsh review can reinforce shame and make avoidance worse. The partner should create commitment while keeping the worker's response sustainable.

Setting only time goals

Hours alone do not prove useful progress. Pair an input measure with a concrete output commitment.

Overcorrecting after a bad day

An extreme catch-up day may yield little extra work and damage the following days. Base the next target on observed capacity instead.

Is it for you?

Best for

It is best for difficult long projects where motivation fluctuates and progress can be measured daily.

Not ideal for

It is not ideal when the accountability partner is punitive, unavailable, or unable to challenge unsustainable plans.

From the transcript

every evening I would uh set deadlines for the next day both input and output

Will MacAskill · 23:30

it would be a review of the day so yeah did I hit my input goal my output goal how much caffeine did I drink…

Will MacAskill · 25:30

I think it increased my productivity I don't know it feels like 20% or 25% or something just from these like 10minute check-ins every day
