Design copy and follow-up conversation choreography around that fact, not around the hope that the customer will \"be reasonable.\"\n\n**Why:** Anchoring is one of the most robust findings in behavioural science ([[anchoring-effect-tversky-kahneman-1974]]); adjustment away from an anchor is typically insufficient even when the anchor was arbitrary. The practical failure mode is the $8,000-online-estimate → $12,000-real-quote case: the seller is climbing out of a hole they dug themselves.\n\n**How to apply:**\n- Default to ranges instead of point estimates ([[rule-default-to-directional-range-ungated]]).\n- When a point number is unavoidable, make the range it sits within visible at the same prominence.\n- In sales-handoff documentation, prepare the follow-up conversation for the upward adjustment — never let the customer first encounter it as a surprise.","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"solar-calculator-inaccuracy-newton-test","title":"Solar calculator inaccuracy: three Wolcott St (Newton MA) homes of 1,885 / 881 / 493 sq ft returned near-identical savings ($30k-$32k) on Google Project Sunroof","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"moving-online-estimator-inaccuracy","title":"Moving industry: online cost calculators \"often cannot reliably predict the true scope\"; reputable movers require in-home/virtual surveys; FMCSA 110% rule applies","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"anchoring-effect-tversky-kahneman-1974","title":"Anchoring effect (Tversky & Kahneman, 1974) — the first number presented becomes a reference point that pulls all later judgments, even when arbitrary","kind":"reference","scope":"business","link_type":"depends-on"}],"incoming":[{"slug":"research-brief-customer-facing-calculators-smb-june-2026","title":"Research brief: customer-facing calculators & tools for SMBs — the honest case (June 2026)","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"article-customer-facing-calculators-win-work-or-backfire","title":"Article (draft): A calculator can win you work — or quietly cost you the deal","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"northcraft-neale-1987-real-estate-experts-anchoring","title":"Northcraft & Neale (1987) — anchoring replicates with REAL-ESTATE EXPERTS: agents' valuations track arbitrary listing prices, despite experts' confidence they don't","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"englich-mussweiler-strack-2006-judges-dice-anchoring","title":"Englich, Mussweiler & Strack (2006) — anchoring replicates with JUDGES: sentences track dice rolls, despite judges' confidence they don't","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"rule-honest-anchor-tool-output-matches-sales-quote","title":"R8 — The tool's number IS the buyer's anchor; sales must be ready to MEET OR EXPLAIN it — bait-and-switch destroys the trust the mechanism case earns","kind":"rule","scope":"business","link_type":"relates-to"}]},"created_at":"2026-06-20T16:50:09.705Z","updated_at":"2026-06-20T16:50:09.705Z"}
