Synthetic users and digital twins promise speed and scale, but can you trust what they tell you about human behavior? This session makes the case for synthetic users, grounded entirely in evidence rather than hype.

Drawing on a large validation study—11,000+ synthetic interviews across six commercial AI models and three countries (US, Brazil, Peru)—Adriana Rocha shows where synthetic users genuinely earn your confidence, where they don’t, and the rules that distinguish the two.

The core message is not “trust them” or “don’t.” It’s that a synthetic user is a behavioral instrument — reliable when calibrated for the right question, misleading when it isn’t. Attendees will leave with a practical map of which research questions synthetic populations answer well today, which they can’t, and how to combine synthetic exploration with human validation responsibly.

What you’ll learn

  • Where synthetic users are genuinely trustworthy, and where they quietly fail
  • Why richer personas don’t mean more accurate ones
  • The identity-to-behavior gradient that predicts reliability
  • A hybrid “Phase 0” workflow: synthetic to explore, human to confirm
