Why finns are soo honest?

I am foreign student from a asian country, By default ,i always expect 80% online deal or offline deal will be fraud and About friendship i always expect all are snakes and about me bite me .

but in finland the scenario is different , When doing online deals,buying cars, Finns never lie, finns are super honst about friendship though because it us not easy to make finns as your friend. . Does finnish theif also ask people permission while stealing something ?😃😆
