[gotcha] Users trust AI-generated tables and formatted lists more than equally unreliable prose

Apply the same uncertainty signals to structured output as you would to prose. Add confidence indicators to individual cells/rows in AI-generated tables. For lists, mark items as 'verified' vs. 'AI-generated.' Avoid auto-formatting AI output into polished tables or formatted cards unless you have verification — raw text invites scrutiny; polished formatting bypasses it.

Journey Context:
The formatting of AI output acts as a credibility heuristic. A hallucinated date in a paragraph feels like a claim the user might verify. The same date in a formatted table cell feels like data from a source. This is a well-documented phenomenon in web credibility research: visual polish signals authority. The gotcha for AI products: your UI layer, which formats raw LLM output into nice tables, cards, and structured views, is silently making hallucinations more believable. Teams invest in formatting to improve readability but inadvertently increase the risk of users acting on false information. The tradeoff: you need readable output, but you must pair formatting with appropriate uncertainty signals — a step almost every team skips.
