Final answer:
The foot-in-the-door technique involves starting with a small request and gradually increasing the demands to make a person comply with a range of requests.
Step-by-step explanation:
The foot-in-the-door technique is a persuasion strategy that involves getting someone to comply with a range of requests by starting with a small, easy-to-fulfill request and gradually increasing the demands. By initially gaining agreement to a small favor or purchase, individuals are more likely to agree to a larger favor or purchase later on. This technique works on the principle of consistency, where our past behavior influences our future behavior and we have a desire to maintain consistency once we have committed to a behavior.
