>Accept that most people flake

This is a thing that's always surprised me when I've been in the US. How common it is to enthusiastically arrange to do some activity together, get a meal, play a game, have a drink, whatever, and then for people to just call it off at the last minute. It seems much more socially acceptable to do so than either the UK (where I live) or France (where I have lived and still visit regularly).

The loneliness thing seems common across Europe too though so I'm not suggesting this is the root of the problem. But I do think that whilst this is a global problem the solutions are likely to be local, working with and leveraging different cultural norms.

I think that most of us Europeans think the Americans are over enthusiastic, which can give us the impression that they want to do something more than they actually do.

I think your comment about social acceptance in the UK is slightly off. It's person dependent. I would say my experience aligns closer with the 50% mark. It's a massive variant from person to person. I have friends that will turn up to anything, rain or shine, sickness or in health. Equally, I know people that would flake on a wedding because they stubbed their toe or the latest season of [insert meaningless reality show] came out.

> enthusiastically arrange

Anything but a purely positive or enthusiastic response is not allowed in US culture.
