Commitment and consistency: the free-trial card trap

The episode follows a free-trial flow that asks for payment details before the trial begins. It names commitment and consistency: after a person makes a small commitment, a later paid choice can feel like the consistent way to continue. The resistance move is concrete: set a calendar reminder for the trial end date before entering the card number.

Freedman and Fraser's 1966 study describes the foot-in-the-door technique, where agreement to a small request is followed by a larger request. That study provides the behavioral pattern used here to explain why an early commitment can shape a later choice. A plain-language account of the technique describes the same small-request-then-larger-request sequence. 12
