# Auto-renewal degrades subscriber quality by filtering for naïve consumers

**Claim:** Because [[concept-inert-sophisticated-consumer|sophisticated consumers]] actively avoid auto-renewing contracts, the resulting subscriber base under auto-renew is disproportionately composed of [[concept-inert-naive-consumer|inert-naïve consumers]] — who can be **up to five times overrepresented** relative to the population.

**Evidence:** The selection effect degrades overall subscriber quality: these users are the least engaged, most likely to become [[concept-zombie-subscribers]], and most likely to generate [[concept-brand-spite]] when they churn.

**Confidence:** High. **Testable:** Yes (cohort engagement analysis by acquisition default — see [[prereq-cohort-analysis]]).

**Enrichment / validation:** The *direction* is robust — the paper finds auto-renew offers attract more inert, less-engaged subscribers, with roughly *half of auto-renew takers rarely using the product while continuing to pay*. However, the specific **'5× overrepresentation' figure is not explicit in public drafts** and is likely a model-based/internal estimate; published work stresses naïveté is rare in the overall population, so practitioners should be cautious about assuming very large multipliers without their own cohort distributions.
