Before sharing a viral claim, stop reading the post vertically and search laterally: identify who is making the claim, find the original evidence, and see what independent reliable sources say. Likes, confident captions and repeated screenshots measure circulation, not accuracy.
Write the claim in one sentence
Separate the testable assertion from outrage, prediction and opinion. Include who supposedly did what, where and when. If the post says this changes everything without stating an event, there may be nothing concrete to verify. Record the post's date; old material is frequently recirculated as new.
Leave the page
Open new tabs and search the account, publication or domain. Stanford's Civic Online Reasoning research teaches lateral reading: professional fact checkers investigate a source by consulting other sources rather than trusting the site's own About page. Look for ownership, corrections, expertise, prior reliability and whether reputable outlets cite the account.
Trace the evidence upstream
A screenshot of a headline is not the article. A clip is not the full speech. Search a distinctive phrase, document title or quoted sentence. Locate the original report, court filing, study, press release, transcript or full video. Then read what it actually says. A real document can be paired with a false caption, and a preliminary study can be presented as settled proof.
For government actions, use the agency or court record. For a company's product announcement, use the company source but seek independent reporting for limitations and impact. A primary source establishes what the organization said or filed; it does not automatically validate every claim it makes about itself.
Check images and video
Use reverse-image search or Google Lens to find earlier appearances and alternate captions. Inspect landmarks, weather, language and shadows, but do not overstate visual guesses. Extract key frames from video and search them. Look for the earliest credible upload and full sequence. Compression artifacts alone do not prove AI generation, and the absence of an AI detector warning does not prove authenticity.
Use fact-check search intelligently
Google's Fact Check Explorer indexes fact checks from publishers that use ClaimReview markup. Search the central phrase and names, then read the linked methodology and evidence. A fact check about a similar claim is not automatically a verdict on this version. Compare dates, wording and media.
Account for breaking-news uncertainty
Early reports can be incomplete. Prefer outlets that explain what is confirmed, attribute information and correct errors visibly. If reliable sources disagree, state the uncertainty or wait. Sharing with just asking questions still amplifies the claim.
A five-minute verification pass
- State the exact claim and date.
- Investigate the source in new tabs.
- Find the earliest primary evidence.
- Compare at least two independent credible reports.
- Reverse-search important images or key frames.
- Check whether context, location or timing changed.
- Share only what the evidence supports, with the source link.
Sometimes the answer is not false but unverified. That is a useful conclusion. The responsible response to missing evidence is to withhold certainty, not fill the gap with the most exciting explanation.
