A Finn here. And just as many other finns, I'm confused to why Finland ranks at the top. Yet, this seems like a case of someone looking to disprove a theory and thus finds the arguments. For example; Health metrics isn't a good measure, considering that Scandinavia has free health care, and this leads to more cases of mental health issues are recorded. Suicides aren't a great metric either, considering that Swedes and Finns have fairly high level of access to guns. I do agree that happiness is a term that is difficult to define, and that "happiness" is a bit misleading. "Content" is a better description.

Also, I think it's easy to misunderstand the Finns from the surface of us. We don't exhibit happiness, and we don't express happiness in a way that is easily observed. Finland ranks at the top of trust in other people, and being one of the least corrupt countries in the world. Those two metrics are a hint into how we Finns relate to other people. Also, it's difficult to get to know Finns, and for this reason it's difficult for outsiders to understand the Finns and the mentality.

On the anecdotal side, earlier this year I solo-traveled the US for 4 weeks, and out of those I got into deeper conversations, I was struck by how sad people were. That made me more convinced that I live a very happy life, in a happy place.
