Ridiculous research. Bad study design. The proportion of sample so-called wallets (I will call them “unimportant things” due to their appearance) and total population for each country is NOT the same, which is problematic. Also this study doesn’t take the discrepancy of countries into account. For example you noticed that Japan is “different” but you didn’t notice China, which you have to admit. I don’t know if there exists discrimination here. Besides, I wonder if the authors noticed something called LOST&FOUND office. Putting wallets there can’t be defined as NOT HONEST. I also wonder why SCIENCE published this paper when it has ridiculous biases.
