Helsinki is the most honest city in the world.
According to an unusual experiment that was conducted in 16 cities around the world, the capital of Finland was declared the city with the most honest people. The research experiment entailed putting 12 wallets with a phone number, a family photo, and a little cash around the city. 11 out of 12 wallets were returned to their owners in Helsinki, whereas in other countries only half of them were returned.
