From the article: "lonely individuals tend to perceive that their ideas are not shared by others"

I wonder how the current loneliness epidemic is intertwined with our current social/political climate and "us vs them" polarization.

I suspect almost everyone has some secret disagreements with their in-group, even if only by a matter of degree, but are afraid to voice that opinion. There have to be tens of millions of Americans who identify as a INSERT_POLITICAL_IDENTITY but disagree with some aspect of that group's platform, narrative or goals.

It's a wonder that anyone doesn't feel like their ideas are not shared by others.
