The Lowball Technique is a psychological strategy used in persuasion and negotiation. It involves initially presenting a favorable offer to gain commitment from a person, only to later reveal additional costs or less favorable terms. This technique exploits the tendency of individuals to stick with their initial decision, even when the conditions change. This method is often seen in sales and marketing, where a seller might advertise a product at a low price to attract customers. Once the customer shows interest, the seller may introduce extra fees or conditions, relying on the customer's commitment to complete the purchase despite the changes.
