Reliability / source

Find out whether this source, measure, or account can be trusted for this specific decision.

Planning the one big trip you'll take this year, you find a hotel with hundreds of glowing reviews. Then you notice things: many reviewers have exactly one review to their name, several use oddly similar phrasing, and the fiercest praise clusters in the same two weeks. Before this hotel gets your week and your money, the real question isn't "is it good?" but "can these reviews be trusted at all?"

Reliability / source is the evidence job of finding out whether a source, measure, or account can be trusted for this specific decision, before you weigh what it says. Trust is not general; a source can be reliable about one thing and worthless about another. The cue is leaning on evidence whose origin you haven't examined, especially when someone profits from your belief. The operation: check the source's closeness to the facts (did they stay there?), their track record, their incentives (paid placement, review farming), and whether supposedly independent accounts share one origin. Then cross-check against a source with different incentives, like a mapping app's photos or a forum with verified stays. What changes is that you weight evidence by its credibility instead of its volume. Skip the vetting when the stakes are trivial or you can verify the claim directly yourself.
