A good deal of the current Scottish population are descended from the Irish, which goes some way to explaining that side of your comparison, but I am not aware of Finland being particularly cloudy.
I have not consulted any climatic records, but I would have expected it to be less cloudy than the rest of Scandinavia, really, since the rain will have been deposited on the mountain in Norway and Sweden before the air masses reach Finland.

but clouds don’t really affect light levels that much, meanwhile up north it’s just… straight up night for most of the day during the winter.
The upper third of Finland is in the Arctic circle, I should remind you.
Do you disagree that the further away from the equator you go, the less sun you get, and the less effective that sunshine is?
I should like to remind you that Finland has the highest prevalence of blondes in the world. And what is that an adaptation to, do you know?

However it’s a bit more complex as to why Northern Europe has less gingers, and I’m sure it’s not because there’s no invest.
