This is the most important form of competence for a leader of government. There is no chance any leader would have adequate expertise in every subject they would need to be versed in in order to lead their nation. They _must_ bring in and rely on SMEs to make informed choices. (Of course they still have to make the choice.)
Climate, general health, age distribution and other unknown factors certainly play into it, and could easily affect the rate of deaths by such a factor. But I smell a rat when I hear that Norway get 5% positives and NYC gets 25% when they test. Also, Italy makes it clear that even with a relatively consistent approach to hunting down the corpses, a big factor can get lost in the noise. Way above 2x.
So it's not trivial to compare this between countries, but it seems feasible to (by critical judgement) at least distinguish between a wildly incompetent and a good response.
You see, as of today we have 2,473 confirmed cases and 33 deaths in Thailand. Denmark, on the other had 5,819 confirmed cases and 247 deaths as of a couple of days ago. I am sure the data is noisy and that testing here is not nearly widespread enough. But the bodies are not piling up and we don't really have the kind of censorship here that would keep it hidden if there were a lot of deaths from Covid-19. And most importantly, the words "competent government leadership" and "Thailand" should never be uttered in the same sentence.
So I guess leaders have done some things right by listening to the right experts (a form of competence I suppose). Or maybe it's the weather (popular theory that seems to have been dismissed). Or cultural habits have saved Thailand. Because I look to more advanced countries, especially in Scandinavia, and don't understand why they are doing so much worse than where I live.
