Most misinformation does not look like a lie. It looks like a screenshot, a brief video, or a quote that confirms something you already half-believed. That is what makes it effective — and what makes a small set of slow, deliberate habits so useful.
This guide collects the habits used by professional fact-checkers, adapted for the kinds of posts most readers actually encounter.
Identify the original source
Click into the account, then into any linked source. Screenshots of news headlines are easy to fabricate; the underlying article either exists at the publisher's domain or it does not. Quotes attributed to public figures can be searched on the publisher's own site.
If a post does not name a source, treat the claim as unsupported until you find one.
Use a second tab, not a search bar
Open a fresh tab and search for the claim independently. Fact-checkers call this 'lateral reading.' It avoids the trap of evaluating a source on its own terms — the design and tone of a site are not evidence about its accuracy.
Reputable fact-checking organizations such as the Poynter Institute's IFCN-verified signatories are a useful starting point, especially for high-profile claims.
Watch for context collapse
A real quote presented out of context can be more misleading than a fabricated one. Old footage repurposed as breaking news is a recurring pattern. When you see a striking video, search for the earliest appearance of the same clip; reverse-image search and platform-specific search tools make this routine.
Dates matter. A genuine news story from three years ago can mislead when it surfaces today without context.
AI-generated content
Image and audio generation are now good enough that visual cues alone are unreliable. The defenses that still work are provenance — where did this come from, who first posted it, does any reputable outlet carry it — and skepticism about extraordinary claims.
Treat unsourced, viral, perfectly-on-narrative content with the same suspicion you would give a chain email.
