Yes - things that used to be confined to a certain newspaper (now, I think, gone) are now all over the radio and TV.
I wasn't thinking so much of "loners" (which I take to mean complete solitaries) but simply people who need to spend some time alone, or children who prefer adult company.
Even witches (in persecution times) weren't solitaries. It's a long time since I knew an anthropologist who wrote a thick tome on this in the 1960s, but the impression I got from him was that it was their sought-after-ness that often sparked off witch-hunts, rather than their solitariness.
