# Most inert consumers are sophisticated and aware of their inertia

**Claim:** Among consumers who exhibit genuine inertia (defined as an **85% monthly chance of not canceling** a subscription they'd prefer to drop), **83–92% are 'sophisticated'** — fully aware they will likely forget to cancel, and proactively factoring this risk into their decisions.

**Evidence:** A structural model estimated on the field-experiment data (see [[prereq-structural-modeling]], [[entity-inertia-field-experiment]]). This underpins the [[concept-inert-sophisticated-consumer]] type and the paradigm shift in [[contrarian-consumers-not-passive]].

**Confidence:** High. **Testable:** Yes (structural estimation / choice modeling).

**Enrichment / validation:** *Robustly supported.* One recent version estimates **35–55% of the population is non-inert**; the rest are inert with an **81–85% monthly non-cancellation rate**, of whom **83–92% are sophisticated** and naïveté is rare (a few percent). Earlier drafts reported a smaller sophisticated share (58–67%), reflecting model differences. Independent rebate research (instant rebates / 'buy baits') corroborates that consumers are often sophisticated about forgetting — though a counter-perspective notes sophistication may be lower for opaque, non-salient frictions.
