Deepfakes Explained for Teenagers
What deepfakes are, how they’re made, and a few honest questions to ask before you believe (or share) the next viral video.
A few years ago, if you saw a video of a famous person saying something outrageous, you could pretty much trust it. Today, that’s no longer true.
What is a deepfake?
A deepfake is a video, image, or audio clip that’s been generated or altered using AI to make it look and sound like someone said or did something they never actually did.
How they’re made
AI models learn from thousands of examples — photos of a face from different angles, or hours of someone speaking. Once trained, they can generate new frames or new speech that look and sound like the original person. What once needed a Hollywood studio can now be done on a laptop.
How to spot them
- Look at the eyes. Blinking often looks off in deepfakes.
- Watch the mouth. Lip sync can be slightly out of step with the audio.
- Check the lighting. Shadows on the face may not match the scene.
- Reverse-image search or look up the original quote. Reputable outlets will confirm or deny it.
What to do when in doubt
The best defence isn’t a checklist — it’s a habit. Before you share, ask yourself: Who benefits if I believe this? Would a serious news source cover this? Am I forwarding it because it’s true, or because it’s outrageous?
Deepfakes work because they exploit trust. If you slow down for ten seconds, most of them lose their power.
