Un youtubeur US teste qui rends les protefeuilles trouvés :

got 200 wallets and dropped them in 10 cities to collect data to rank the honesty of the cities and to build a profile of an honest person. We looked at variables such as male v. female, age, high income v. low income, religious v. non-religious, small town v. big town.

résultats ? 2/3 de retours quelque soit le genre/revenu/religiosité/...

bon c'est aux US...
