Which term refers to AI-generated video or audio that makes someone appear to say or do something they never did?

• A. Confirmation Bias
• B. Bandwagon Effect
• C. Echo Chamber
• D. Deepfake

Answer: (D)

Recognizing AI-generated media manipulation helps you assess credibility in what you watch. The term for video or audio created with AI that makes someone appear to say or do something they never did is deepfake. Deepfakes use advanced generative AI to synthesize realistic images, voices, or scenes, so the result can be convincing enough to mislead viewers or damage reputations. The other concepts describe how people think and share information rather than how the media itself is produced: confirmation bias is the tendency to favor information that confirms preexisting beliefs; the bandwagon effect is jumping on a belief because many others do; an echo chamber is an environment where only similar viewpoints are shared and reinforced. Knowing this helps you focus on evaluating authenticity—checking sources, looking for inconsistencies, and using verification tools when you encounter suspicious clips.
