Test whether repetition represents independent evidence or only makes a claim feel familiar.
Open situation →Reasoning Practice · Starter
Ten articles repeat one report
A claim appears in ten articles. Following the links shows that nine articles cite the tenth, which cites one small report.
Your decision
What should determine confidence?
Show the best first move
B. The quality of the original report and any genuinely independent evidence.
Why this move helps
Ten repetitions do not equal ten independent observations. Source tracing reveals the evidence structure behind the apparent agreement.
Evidence still missing
- Method and sample of the original report.
- Independent replications or datasets.
- Whether later articles add new evidence or only repeat the claim.
Evidence note
Illusory truth may make the repeated claim feel more credible. The main operational problem is source dependence, which can be checked directly.
Next action
Draw a simple source tree and assess each independent root.
Best first lens
Illusory Truth Effect
Use the lens to ask a better question. It does not prove that a person or team has a cognitive bias.
Other defensible lenses
The situation may have more than one explanation.
