Definition:
Foot in the door is a manipulation technique in which a small, seemingly harmless request is made first in order to increase the likelihood that a larger, more significant request will be accepted later.
Usage Context:
Common in sales, marketing, fundraising, political campaigning, platform onboarding, and institutional processes where initial consent is used to normalise escalation.
Critical Note:
Foot in the door relies on gradual commitment rather than informed agreement. By framing each step as minor or reasonable, systems reduce the likelihood that people reassess the overall trajectory, making withdrawal feel disproportionate or unreasonable.
