I started reading up on the whole "loneliness pandemic" narrative because this seems like a literature where the age-period-cohort problem may be relevant (or maybe it isn't?).
Here's data from Australia (HILDA), average agreement with the statement "I often feel very lonely" (SD of ca. 1.8).>

Finished teaching my first class of the semester. Next instructor came in, put down her stuff, we chatted a bit, I left. 30 seconds later she ran out in a panic...
I was wearing BOTH my backpack (black, generic-looking) and hers (black, generic-looking). One on the front, one on the back. 🤦♀️

What’s the worst question someone can ask after you tell them your profession? For linguists, it’s definitely “how many languages do you speak?”, but I’m curious what else is happening to the rest of y’all out there?!

new paper by Sean Westwood:
With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research
