R7 — When the owner can read a number off a screen, have them do so
Rule
Rule: When the answer is a number the owner can observe on a screen (GBP review count, own analytics, live SERP), instruct the owner to look — not estimate.
Why: Junco 2013 (Junco 2013 — Facebook self-report overstates logged use by ~5.6x) — recalled counts overstate by ~5.6x in a representative validation study. Imboden 2023 (Imboden 2023 (US Census/IRS) — survey self-employment income roughly DOUBLE the admin figure) — even revenue, the most "obvious" number, doubles when self-reported. The cure is to remove recall entirely.
How to apply: "Open your Google Business Profile in a new tab and count the reviews." "Search for in and tell us how many businesses appear above you." Where technically cheap, the widget should FETCH the data directly (Brief 1 Stage 3 recommendation).
