Science and health claims, checked against the paper

The phrase a study says is doing an enormous amount of unearned work.

Sample size and selection decide what a health finding can support, and both are usually the first details removed when a study becomes a story. A result from a few dozen participants in a controlled setting is not a population-level claim, however confidently it is repeated.

Replication is scored separately because in several fields a single unreplicated result is weak evidence, and the popular version rarely mentions that no one has reproduced it.

Nothing here is medical advice. It is a reading of what the evidence establishes and where its public use has gone past that.

Questions

Is this medical advice?

No. It scores the strength and use of public claims. Decisions about your health belong with a qualified clinician.

Why does replication matter so much here?

Because an unreplicated single result is a starting point, not a conclusion, and the distinction almost never survives into the headline.

Do you cover nutrition and fitness claims?

When they reach the scale where people are making decisions on them, yes.

Where this stands today. The scored record currently covers artificial intelligence and cybersecurity claims. This subject is in scope and has not been scored yet. We are telling you that rather than implying a back catalogue that does not exist. The record shows exactly what has been scored.
