(focus groups, 48 US adults; follow-up experiments) found numeric ranges in TEXT increased worry and perceived risk, but the SAME uncertainty shown in a VISUAL (a 0-100% bar) DECREASED worry and perceived risk.\n\n**Source:** Han et al. focus groups + follow-up experiments. Limited sourcing — single research line.\n\n**Confidence:** Single-source.\n\n**Why this matters for Candid:** The widget should present uncertainty visually — a horizontal scale with the owner's position marked, plus the band — rather than only textually. The same uncertainty content lands differently depending on format.","rationale_body":null,"metadata":null,"links":{"outgoing":[],"incoming":[{"slug":"research-brief-smb-widget-presenting-tiers-june-2026","title":"Research brief: SMB widget presentation layer — tiered results without overclaiming (June 2026)","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"rule-four-tiers-with-visual-scale-and-drivers","title":"Rule — 4 tiers max, plain labels, visual scale, drivers shown","kind":"rule","scope":"business","link_type":"depends-on"}]},"created_at":"2026-06-23T19:16:03.403Z","updated_at":"2026-06-23T19:16:03.403Z"}
