Bias

Identify who produced the report, whether suitable experts were involved, whether the work was peer reviewed and whether funding or campaigning interests might introduce bias. Reputation alone is not enough, but an unsupported social-media post should not be treated like a transparent, peer-reviewed analysis.

Reviewers also exercise judgement, so different reviewers can reach different conclusions and bias may influence an evaluation. Using several suitably qualified reviewers can provide more than one expert opinion, but it does not remove every limitation.
