What this video covers
Synthetic users are AI-generated stand-ins for research participants: prompt a model to "be" a persona and answer your interview or survey questions. They produce fluent, plausible, instant responses - which is exactly the danger. They reflect patterns in training data and the assumptions in your prompt, not the lived experience of a real person, so their confidence is untethered from truth.
Could you reliably tell the AI answer from the human one? Most people can't - synthetic responses are fluent and plausible by design. That's the trap: they pattern-match what a user "should" say and deliver it with total confidence, while telling you nothing a real person's messy, surprising, contradictory experience would. Plausible is not the same as true.
