You are the person focusing on complaining specifically. I stated that the Nordics are far from being the happiest people in the world, and that is not by counting how much people complain.

> This is inherently paradoxical and hence nonsensical. If you successfully convince yourself that you are happy, you are happy.

If people are visibly unhappy but tell you that they are very happy, that doesn't mean that they've become happy by convincing themselves. That's like a guy screaming and punching you while he's saying that he's very calm. It's not reality, it's delusion.

When somebody successfully convinces themselves to be happy, they don't continue their lives showing all the behaviour and attitudes of an unhappy person. You can also outwardly tell that they are happy.

> That you think you know better than people themselves whether they are happy is just rude and insulting.

Oh, the insolence!

Explain to us in what way you have determined that you know better than people themselves how happy they are, then, please.

Given what you've written I have no reason to believe that you are capable of telling whether people are happy or not at all, as I simply don't believe you will pick out genuine markers of unhappiness from culturally or personality dependent traits that are not.
