Loyalty Economics
Myth:Loyal customers cost less to serve, pay more, and evangelize for free.
Evidence:Studying four companies over 16 months, Reinartz & Kumar found only a modest correlation between customer longevity and profitability: long-tenure customers expected discounts, were no cheaper to serve, and were not reliably the best word-of-mouth sources.
Some loyal customers are very profitable - the error is treating tenure as the signal. Segment on profitability and tenure together.

Loyalty Economics
Myth:CX improves by optimizing the touchpoints you control, one at a time.
Evidence:The field's anchor framework shows customer experience is cumulative across the entire journey - including social, environmental and competitor touchpoints the firm doesn't control - so single-touchpoint optimization misses the real drivers of satisfaction and loyalty.
Loyalty Economics
Myth:Spread the marketing budget across every driver of satisfaction.
Evidence:Modelling customer equity directly, Rust, Lemon & Zeithaml show reallocating spend to the highest-leverage driver of customer equity beats across-the-board investment - in their airline application, the concentrated strategy maximized return on marketing.
Onboarding
Myth:Churn is a late-lifecycle problem.
Evidence:Most avoidable churn is set in the first sessions: users who reach a core activation action early retain at multiples of those who do not.
Unit Economics
Myth:Growth is an acquisition problem.
Evidence:Modest retention improvements compound through the customer base and typically move profit more than equivalent acquisition spend, because retained revenue carries no CAC.
LTV
Myth:Early cohort LTV projections are reliable planning inputs.
Evidence:LTV curves flatten unpredictably; projections built on the first weeks of a cohort routinely overstate long-run value.
