The words they use in the room, and what they mean
Every term here is a word from the sales room, the psychology behind it, or the rules that may apply afterwards. Each entry is one or two sentences with a source. General information, not legal advice. Where a term rests on a legal rule, check the date, because rules change.
Words about the pitch
Anchoring
Relying on the first number or fact you see when judging later ones [S33].
Cold state and hot state
Calm versus emotionally or physically aroused states. Decisions and predictions differ between them [S16].
Commitment and consistency
The tendency to act in line with what you have already agreed to or said [S13].
Door-in-the-face
Asking for a very large favor first, then a smaller one that is accepted more readily [S12b].
Earnings claim
Any statement about what buyers may earn. For sellers the Business Opportunity Rule covers, an earnings claim needs a reasonable basis and written substantiation [S60].
Low-ball
Securing your agreement first and revealing added costs later [S20].
Persuasion knowledge
Your awareness of a seller's goals and tactics, which you can use to cope with a persuasion attempt [S21].
Psychological reactance
The motivation to reassert a freedom that feels threatened [S15].
Scarcity
Valuing something more because it is limited or disappearing [S15].
Sunk cost
Past, unrecoverable spending that still influences your decisions [S19].
Words about the contract and your rights
Automatic renewal
A contract term that continues or renews charges unless you cancel. California regulates it under Business and Professions Code 17600 and following, and its 2025 amendments apply to contracts entered into, amended or extended on or after 1 July 2025 [S44].
Business Opportunity Rule
The FTC rule at 16 CFR Part 437, which applies to sellers who solicit you to start a business and promise locations, outlets, accounts or customers, or to buy back your goods or services [S60]. In January 2025 the FTC proposed extending it to coaching. As of October 2026 the proposal is not final [S10].
Chargeback and billing-error dispute
Asking your card issuer to reverse a charge. For credit cards, the billing-error process requires written notice within 60 days of the first statement showing the charge [S38].
Debt validation notice
A collector's notice of the debt and your right to dispute it, which must come in its first communication or within five days afterward [S48].
Integration clause
A contract clause saying the written document is the whole agreement, which can limit your reliance on oral promises. Ask a lawyer about your state [N20].
Negative option
An offer that treats silence or inaction as consent to keep charging you. The FTC's 2024 "click to cancel" amendments were vacated by a federal appeals court on 2025-07-08 [S45]. The FTC asked for public comment on a new rulemaking in March 2026, and as of 2026-10-27 no replacement rule is in effect [S46].
Rosenthal Act
California's fair debt collection law, Civil Code 1788 and following. It can reach original creditors collecting their own debts, because its definition of a debt collector includes anyone who regularly collects debts in the ordinary course of business [S52].
Seller Assisted Marketing Plan
California's term, in Civil Code 1812.200 and following, for certain offers marketed as a way to begin or run a business. Conditions include a total initial payment over $500 and a cash payment under $50,000, and the law lists exclusions [S43].
