The Honest North Europeans

If you have to lose your wallet, do it in Helsinki but definitely don't do it Lisbon.
In a Social experiment conducted by the journal, Science, 98% of wallets containing £50 in the local currency purposely dropped on the streets of the Finnish capital were returned whereas only 8% found its way back to the rightful owner in the Portuguese Capital.
In the 16 European Capital the experiment was held, none of the cities surveyed brought shame on itself by returning none of the wallets but overall, only 47% of the wallets were returned so if you’re most likely to get your wallet back in Helsinki, and least likely to do so in Lisbon, the experiment showed that is there an honesty arc running across Europe, declining as you travel from the continent’s north to south.
Cities closer to the top end of Europe generally score better than those closer with Budapest returning 66%,  Moscow and Amsterdam handed back 58%, 59% of wallets found in Ljubljana and Berlin were reunited with their owners and Warsaw and London both scored 41%.
Of the least honest, the residents of Bucharest and Zurich as only 33%  saw their wallets again and 25% in Prague but the worst places to wave goodbye to your wallet is Madrid with 16% and Lisbon with their measly 8%.
Only three cities on other continents were subjected to the Wallet Experiment, 33% of resident in  Rio, New York was 66% and in Mumbai 75% saw the wallet again.
