strong evidence
Claim follows directly from well-controlled data, ideally confirmed by an independent method.
Reading critically and thinking experimentally. For each paper, what it claims, how well the evidence supports it, and what I would test next.
Claim follows directly from well-controlled data, ideally confirmed by an independent method.
Data support the claim, but a key control, replicate or orthogonal method is missing.
Claim goes beyond the data, or relies on correlation where causation is stated.
Interesting but early: preprint, small n, or a single experiment.
