Source-incentive meta-finding: nearly every "calculators convert" source SELLS calculators; independent material clusters on the risks
Summary
Finding: Across the entire body of material on customer-facing calculators, nearly every source making positive conversion claims SELLS calculators, lead-gen SaaS, or calculator builds. Independent material clusters on the risks — law firms on liability (A detailed online estimate with no reasonable basis can expose you to misrepresentation or negligence — even when labelled "estimate"), academics on anchoring (Anchoring effect (Tversky & Kahneman, 1974) — the first number presented becomes a reference point that pulls all later judgments, even when arbitrary), consumer / industry bodies on estimate accuracy (Moving industry: online cost calculators "often cannot reliably predict the true scope"; reputable movers require in-home/virtual surveys; FMCSA 110% rule applies).
Confidence: Verified — the asymmetry is reproducible by checking the source list.
Why this matters for Candid: This asymmetry is itself the finding. It justifies the brief's overall posture: when someone produces a stat in favour of building a calculator, check who paid for it. When the stat warns against one, check whether the source is selling the in-person alternative (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). Pair with Caveats for the customer-facing-calculators brief: every conversion-lift figure is unproven; nearly all are vendor-self-reported.
