Source Check

Investigate a claim by judging each document — and learn the hard way that one lone forgery can sink your verdict.

How to play

Each case presents a claim and a stack of source documents — letters, photos, articles and more. Mark each source Accept or Reject, then deliver a verdict on whether the claim is supported. Scoring rewards trusting reliable, corroborated evidence and punishes accepting a lone or forged document.

• Read the claim and weigh every source against it
• Accept the sources you trust as evidence; reject the rest
• Deliver your verdict — supported or refuted
• Accept only reliable sources that another reliable source independently corroborates

Controls

• Desktop: click Accept or Reject on each source, then click Deliver Verdict
• Phone & tablet: tap the Accept/Reject buttons and Deliver

Tips & strategy

• A single document that nothing else backs up is risky — corroboration is what makes evidence trustworthy
• Forgeries are designed to look convincing; rejecting one is worth more than accepting two genuine sources
• Easy, Medium and Hard add more documents and trickier forgeries
