We originally planned to include Japan but after some initial pilot testing we realized that the country was unsuitable for methodological reasons. Japan has a lot of small “police booths” where people can return lost objects. During our pilot tests, we found that Japanese citizens would not contact the owner but instead drop them off at a nearby police booth. This feature made it virtually impossible for us to assign individual wallets to particular drop-off locations.
That’s interesting. As far as I know, China has the similar feature. Why do you still include China in this paper without any pilot testing. Or do you already presumed some opinion and then just gladly accepted the result since it proved your stereotype on Chinese people?
