# Inert-Naïve Consumer

An **inert-naïve consumer** possesses behavioral inertia but *lacks self-awareness* regarding their tendency to forget to cancel subscriptions.

Unlike their [[concept-inert-sophisticated-consumer|sophisticated]] counterparts, they do not factor the risk of future unwanted charges into their initial decision to accept an auto-renewing trial. Consequently, when a business uses auto-renewal, these consumers are disproportionately filtered into the subscriber base — up to **five times overrepresented** compared to a baseline population (see [[claim-auto-renew-degrades-quality]]).

They frequently evolve into [[concept-zombie-subscribers]] who pay for but do not use the service. While they provide short-term interim revenue, their eventual realization of accumulated charges often results in [[concept-brand-spite]] — severe brand damage. Their type is defined within the [[framework-consumer-inertia-typology]].

**Enrichment note:** Public drafts of the field experiment emphasize that naïveté is *rare* — only a few percent of the total population — with most inert consumers being sophisticated. The '5×' overrepresentation figure describes the selection effect among *takers* and appears to be a model-based or internal estimate rather than a published headline number; the directional selection effect is robust.

**Definition:** A consumer who is prone to forgetting to cancel subscriptions but is unaware of this trait, making them highly susceptible to auto-renewal traps and eventual brand resentment.
