What would it take for you to trust a scientific claim you cannot check yourself?

Most of what we believe about science, we cannot check ourselves. We rely on experts, journals and institutions. That is rational, since nobody can verify everything, but it raises a hard question: what should earn our trust?

Peer review, where independent experts evaluate a manuscript before publication, is one answer, though it has known limits. Others include replication by independent teams, openly shared data, agreement across different methods, and the track record of the people or institutions involved.

We are asking readers to say what, in practice, makes them trust or distrust a claim. A good answer would give an example of a claim you accepted or rejected, say what signals you used, admit any signals that misled you, and describe what additional evidence would have changed your mind.

The aim is a practical, shareable checklist for non-experts that is honest about its own limits.
