Trust your gut.
Is the video saying something shocking? Is it poorly edited? Does the person’s voice sound weird? If so, don’t share it. Fact-check it.
Look at the source.
Who posted the video, what does their profile say, and do their other videos look fake? You might quickly get a sense that you can’t trust them.
Search for other sources.
Imagine you had landed on the video of the giant tree frog. Start with a keyword search—such as “giant frog video”—to find articles from trustworthy news sources reporting on the video. (In this case, you would find an article from CNN proving it’s fake.)
Find the facts.
If you’re not finding any trustworthy articles about the video, see what trustworthy sites say about the video’s topic. (URLs that end in .gov or .edu are usually good options.) For example, it’s easy to verify that tree frogs rarely get bigger than 5 inches.
Do an image search.
Take screenshots of the video and upload them to an online tool, such as Google Images. This “reverse image search” may help you find where else the video appears. If so, compare the video you saw with other versions of it. This can help you figure out where it originally came from and whether it has been edited. •
