Measurement, with the working shown.

BrainScoreDaily measures cognitive performance and publishes how it does it — the scoring rules, the exclusions, the sample, the version, and the limits.

The methodology was published before the first test, so that the standard existed before any result did.

• Digit span — how much can you hold in mind at once? About two minutes. Nothing is stored
• Working memory — what it is, what moves it, and what the evidence actually shows about training it
• How BrainScore works — what we measure, how a task becomes a score, and what the score cannot tell you
• Claims standards — the language we have ruled out in advance
• Privacy notice — no cookies, no analytics, no third-party scripts
