[synthesis] A single hallucination during onboarding destroys long-term retention
Constrain first-run experiences to deterministic or retrieval-grounded outputs; avoid open-ended generation in high-stakes onboarding until the user has a base rate of success.
Journey Context:
First-time users have no prior experience to weigh a hallucination against, so one visible error defines the product as unreliable. Studies on hallucination impact show that negative outcomes greatly amplify distrust, and that prominent errors are decisive. Onboarding flows are especially vulnerable because the user is forming a baseline. The common mistake is to showcase the AI's full generative power immediately. The synthesis is to treat onboarding as a trust-building phase: use deterministic scaffolding, retrieval-grounded answers, or narrow domains for early interactions, and only broaden to open-ended generation after the user has experienced a series of correct outputs.
