Eleven scientific
benefits of writing,
mapped, cited, and prescribed.

How much
writing, exactly?

Pull the sliders. The list on the right checks your dose against the actual protocol each study used — minutes per session, days per week, duration of practice. A ticked box means your dose meets that study’s minimum; it is not a guarantee of the same outcome in your particular brain.

The original infographic landed in 2017 and ran the rounds — a few dozen blogs republished it, and the email kept coming. The science has held up well. The honest caveat is that effect sizes vary by person, prompt, and persistence. None of this works if you write twice and quit.

The version above is the same eleven findings, opened up, made interactive, cited, and prescribed. If you read it and write nothing this week, the infographic failed. Pick one.

Note on the numbers
Each stat above is what the original paper actually reports. Where a study gives a clean percentage (Matthews’s 76% vs 43%, Scullin’s ≈9 min, Bangert-Drowns’s d = 0.17), it is shown. Where the published paper reports significance without a headline percentage (Klein & Boals, Smyth, Emmons & McCullough), the stat reads “Sig.” and the finding paragraph explains what the paper actually measured. The dose calculator no longer predicts effect sizes — it checks whether your dose meets each study’s protocol.
