# Common Mistakes

When verifying, be sure to avoid these common mistakes.

### Not reviewing past verifications

Most verifications follow a simple pattern: read the rules, check the resolution source, and see if the evidence exists. By looking at past verifications, you can learn how to verify properly.

*Example:* In mention markets, verification involves going to the video of the event and finding the timestamp when the listed term was said.

### Trusting but not verifying

Never assume that others have verified correctly. Always double-check the evidence yourself.

*Example:* In *Will Trump say "Zohran" or "Mamdani" this week? (November 3–9)*, traders disagreed on whether Trump said "Mamdani." One user claimed that he said "Zohran," but others pointed out that he did not.&#x20;

### Not doing the research

When verifying, make sure to look closely at the evidence and sources. Go beyond the headlines and see if the proof is strong enough.&#x20;

Non-example: In *Will Israel strike Gaza on November 5?*, some traders thought the market could resolve based on headlines without doing proper research. However, verifiers reviewed the full reports to check whether the sources were valid.
