# Consumer Inertia Typology

A **structural-model classification system** that categorizes consumers by two axes: their behavioral **inertia** (likelihood of failing to cancel an unwanted subscription) and their **self-awareness** of that inertia.

**The three types:**

1. **Non-inert** — Consumers who actively manage their subscriptions and reliably cancel services they no longer want. (Enrichment: estimated at ~35–55% of the population.)
2. **[[concept-inert-naive-consumer|Inert-naïve]]** — ~85% monthly chance of not canceling an unwanted subscription, but *unaware* of this tendency; they fall into auto-renewal traps and become [[concept-zombie-subscribers]]. (Enrichment: a rare type — a few percent of the population.)
3. **[[concept-inert-sophisticated-consumer|Inert-sophisticated]]** — share the ~85% failure-to-cancel rate but are *highly aware* of it (**83–92% of all inert consumers**). They calculate the risk upfront and actively avoid auto-renewing trials, producing [[concept-acquisition-suppression]].

This typology is the analytic backbone for the entire thesis: the dominance of the sophisticated type is what overturns the industry's passivity assumption ([[contrarian-consumers-not-passive]]). Understanding it requires familiarity with [[prereq-structural-modeling]].
