Final answer:
Commitment is more likely to be achieved using the foot-in-the-door tactic, where a small initial agreement paves the way for larger commitments. This consistency principle can be seen in sales scenarios, like upgrading your smartphone purchase with additional services and warranties.
Step-by-step explanation:
Gaining commitment as a response to an influence tactic is most likely to occur when certain tactics are utilized effectively. One such tactic is the foot-in-the-door technique, which involves securing a small initial agreement that leads to a greater subsequent commitment. In the context of sales, this could involve a store owner first convincing a customer to purchase a basic item or service, and then leveraging that initial commitment to encourage the purchase of more expensive products or add-ons. For example, after a customer commits to buying a new smartphone with an accompanying data plan, they may be more susceptible to agreeing to a more costly three-year extended warranty. The underlying psychological principle is consistency, as individuals aim to remain consistent with their past behaviors and decisions, thereby more readily agreeing to bigger requests that align with their initial small commitments.
