Marketing communicates outcomes, offers, or expectations that do not reflect reality. Over-promising and under-delivering.
When marketing overpromises and the product underdelivers, you don't just lose a customer — you lose their trust, their referrals, and their reviews. Alignment between messaging and reality is the foundation of retention.
Ogilvy: "Good products can be sold by honest advertising. If you don't think the product is good, you have no business to be advertising it." Lasker: "The product that will not sell without advertising will not sell profitably with advertising."

Richard L. Oliver's 1980 paper in the Journal of Marketing Research set out the model that still underpins customer satisfaction measurement, including the American Customer Satisfaction Index. Satisfaction is not produced by performance alone but by performance measured against expectation. When customers get more than they were led to expect, satisfaction and repurchase intent rise; when they get less, dissatisfaction follows. A modest product can satisfy if expectations were modest, and an excellent one can disappoint if the marketing set the bar too high.
What it means for this rule: Every claim sets the standard the customer will grade against. Copy that raises expectations faster than delivery can follow shows up later as rising acquisition costs, falling repeat rates and reviews that read worse than the product deserves. Rule 25 asks whether a claim is accurate; this model adds a second question: what will the claim lead the customer to expect?
