What are the most (and least) honest cities in the world? Reader's Digest conducted a global, social experiment to find out.

Our reporters "lost" 192 wallets in cities around the world.

In each, we put a name with a cellphone number, a family photo, coupons, and business cards, plus the equivalent of $50. We "dropped" 12 wallets in each of the 16 cities we selected, leaving them in parks, near shopping malls, and on sidewalks. Then we watched to see what would happen.
