Fair enough. It is then a tough balancing act between the amount of resources (money especially) available for such experiments and the desired size of them to be actually useful. Finland is very small and very homogeneous, so it reduces the number of variables they need to think about. And they are rich enough to afford such experiments. Must be fun for those working on the such problems :)
