Missing the point. It does "always happen" but it doesn't always happen to the same degree or to the same proportion of the population.

The Overton Window can be enforced to varying degrees and contain different percentages of the population.

Contrast the atmosphere during the Cultural Revolution to the atmosphere of a 1990s liberal democracy where the large majority of the population was within the Window.

"There is no culture which doesn't have a strong element of self-censorship for at least some of its members."

while this may be true, it does not necessarily reflect that it is right. often times throughout history shame has been used to control minority groups and people who are less privileged.

which sadly means that popular consensus may not always have the best interest in mind. oftentimes the masses overreact and get it terribly wrong if there is awareness outside of pure groupthink

What are the examples of these shameless cultures? I'd like to join them.

In anthropology, there's a concept of a guilt-shame spectrum:

Traditional American culture (as compared to traditional Japanese culture, for example). See https://en.wikipedia.org/wiki/Guilt%E2%80%93shame%E2%80%93fe...

Traditional American culture is rife with shame. The concept of “manly men” is based on shame. The concept that women are responsible if they attract unwanted male attention is based on shame. The concept that anyone can succeed so if you don’t it’s because you didn’t try hard enough is based on shame.

I could go on?

Most of these aren't really "traditional", they're constructs of the post-WW2 era, where the government & mass media/advertising very consciously tried to institute strong "national unity" norms.

I suspect that the "traditional American" culture GP is talking about is frontier/immigrant culture from c. 1840-1929. There's a good case for that really being a "shameless" culture - you do your thing, I do mine, we'll grab up all the land and all the gold and all the prime industries and not feel bad at all for the natives we're genociding.

I mean sorry but the Japanese have a pretty strong shaming culture according to most of the world, that the things you think they should be ashamed of are not those they are shamed by does not prove any different.
