What’s the difference between being polite and being friendly in US culture?

I’ve often read that Americans are very friendly but keep people at arms length. The theories are that collectivist cultures view social warmth as a friendship quality, whereas Americans do it to make a social situation go smoother.

In casual conversation, when Americans say they “made a friend,” it’s actually an acquaintance.

Having observed my American friends from an immigrant background, I’m often welcomed in first and experience hospitality rather than just politeness, with a more communal atmosphere. Because of that, the average non-immigrant American can sometimes feel cold or distant to me.

My question is, how do Americans know whether someone does actually want to be friends versus them just being social?
