# Acquisition Suppression

**Acquisition suppression** is the phenomenon where the presence of an auto-renewal clause significantly deters potential customers from initiating a trial or subscription.

In the authors' **1.4 million-person field experiment**, auto-renewal reduced trial take-up by **35%** — meaning for every 100 readers who would accept an auto-canceling trial, only 65 would accept the auto-renewing equivalent (see [[claim-auto-renew-reduces-takeup]]). This suppression occurs because the majority of consumers are [[concept-inert-sophisticated-consumer|inert-sophisticated]]; they recognize the contractual friction and opt out to protect themselves from future unwanted charges.

The suppression is so severe that the subsequent retention advantages of auto-renewal never allow the total subscriber count to catch up to the auto-cancel cohort ([[claim-auto-cancel-yields-more-subs]]). This is the mechanism behind the contrarian finding that auto-renewal can *reduce* long-term paid subscribers ([[contrarian-auto-renew-reduces-subs]]).

**Enrichment note:** The published paper reports that **24–36% of potential subscribers avoid auto-renewal offers**; the article's headline '35%' sits at the high end of that empirically reported range, and the 'only 65 of 100' phrasing is a stylized restatement.

**Definition:** The significant reduction in initial trial sign-ups caused by consumers actively avoiding the perceived risk of an auto-renewing contract.
