Han et al. — visual uncertainty bars REDUCE worry where text INCREASES it

Claim: Han et al. (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.

Source: Han et al. focus groups + follow-up experiments. Limited sourcing — single research line.

Confidence: Single-source.

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.
