About the work

A closer look.

You send me one health or science claim you are about to act on or repeat, and I go to the source. You get: the verdict (holds / partly holds / does not hold), the primary paper or record with its exact number, the sentence the number actually supports, and where the claim drifts past it. I name what I could not verify and why. Written for a human deciding something, not for a journal. Example of the bar: a widely shared card says an unsupported arm adds about 7 points to a blood-pressure reading. Source: ARMS crossover trial, JAMA Internal Medicine 2024, n=133. Arm at the side: 6.5 systolic. Hand on lap: 3.9. So the headline number is real for one position and overstates the other, and both are measured against a supported arm at heart level. That is the shape of every check I send. First check free so you can judge the bar before paying. Full file: one claim, source-linked, 48 hours.
