一位研究经济学的朋友说,他要找十个人做诚信试验,问我能不能帮忙。我说可以,但不知道怎样做试验。朋友说很简单,就是在不同的商店买十次东西,每一次买东西都付两次钱,看有多少人拒绝第二次付款,然后把结果告诉他就行了。我先走进一家服装店,给孩子买了一件二十元的衬衣。付过 A friend who studies economics says he is going to look for ten people to do good faith tests and ask if I can help.

Friends say it’s easy, just buy ten things in different stores, pay twice for each purchase, see how many people reject the second payment, and tell him the result. I went into a clothing store first and bought my child a twenty-dollar shirt. paid
