That’s interesting. I don’t know anything about Argentinian politics or society, and my understanding of American politics comes solely through international media(not very reliable). I was just referencing an example to explain my point. I could have said country A and country B. My point was just that the measuring of polarisation is very poor and the alternatives are not complicated and are well known. I really don’t understand why they decided to measure it by asking a single question.

I agree with you intuitively, and I do think you would get similar results if you were to use decent measures. People do usually have a good idea of polarisation in their country. I'm just saying, as far as science goes, this is such a poor measure. Note, I was just using Argentina and USA as an example off top of my head.

There is a problem here which is that the measure was actually asking citizens their opinion on polarisation. This is an issue, for example, Americans might say their country is more polarised because they have Fox and CNN (based on media), but maybe an Argentinian would say the same thing based on some type of geographic polarisation. (Essentially this just measures citizens' perception of polarisation in their country. Well-established measures on polarisation can be found in "Working paper

Conceptualizing and measuring polarization: A review" (Bauer,2019).
