蹺蹺版效應指的是在人際互動中，當一方對對方表達一定程度的善意或幫助，對方在接受這些善意後對於該方的要求或請求會更容易說採納，反之則更容易抗拒。這種現象常見於販售、募資等領域。
在這個實驗中，喬向實驗對象表達了一定程度的善意，使實驗對象在接受喬的可樂後，對於喬賣彩票的要求更容易說採納，從而帶來了高投資回報率。這個實驗結果顯示，即使是不喜歡的人，只要在提出要求之前表達一定程度的善意，對方在接受這些善意後對於該人的要求就會更容易說採納。
蹺蹺版效應可以在廣告、促銷等領域中得到應用。例如，在廣告中先向消費者表達某個產品的優點和好處，再提出購買要求，可以有效提高消費者對於產品的採用率。
The Seesaw Effect
The Seesaw Effect refers to the phenomenon in interpersonal interactions where, when one party expresses a certain degree of goodwill or help towards the other party, the recipient will be more inclined to accept the party's requests or demands. Conversely, they will be more likely to resist. This phenomenon is common in sales, fundraising, and other such fields.
In this experiment, Joe expressed a certain degree of goodwill towards the experimental subject, which made the subject more willing to accept Joe's request to buy lottery tickets after receiving Joe's free soda, resulting in a high return on investment. This experiment shows that even if the person is not liked, as long as they express a certain degree of goodwill before making a request, the recipient will be more willing to accept that person's request after accepting the goodwill.
The Seesaw Effect can be applied in advertising, promotions, and other areas. For example, in advertisements, first expressing the advantages and benefits of a product to consumers, and then making a purchase request, can effectively increase the consumer's adoption rate of the product.
