SOURCE 0 - THE PANELIST WHO WAS NEVER THERE EVALUATES THE EVALUATOR

Synthetic-persona providers label a minority of their population "human-grounded" to distinguish it from algorithmically sampled records. That label confirms a record traces to a real panellist's account — not that the person who supplied the answers matches the account's demographic profile. The market research industry already documents this failure as participant misrepresentation. Where the mismatched respondent is a minor, GDPR Article 8's parental-consent verification duty becomes unreachable by design.
