Will people's sensitivity to the same thing decrease with repeated contact?

I think economic theory can solve your problem. In economics, there is a theory of marginal decline. Marginal diminishing effect means that if an input factor keeps increasing to a certain output value, the increment of products provided will decrease when other conditions remain unchanged. German economist Gehlsen once put forward a law about pleasure: the same pleasure is repeated, and the enjoyment it brings gradually decreases. Someone did an experiment. A man without shoes accidentally got a pair of shoes for him to evaluate. Whether they followed the trend or not, he gave them high marks at once. Then there was a surprise. He had a chance to keep getting shoes, but when he continued to grade the shoes behind him, his score became lower and lower. The satisfaction brought by "the next pair of shoes" gradually decreases, which is the theory of marginal decline. Therefore, people's sensitivity to the same person, the same thing, the same life and the same story will definitely decrease with repeated contact. If you are satisfied with my answer, please nominate me as the best answer. Thank you!
