I see this as a manifestation of the loss of teaching effective communication skills. This takes a moment to explain, so please slow down and consider this: before the cultural revolutions of the 1960's, general education included more emphasis on communications conflicts and resolutions of them. For example, every school had a debate team, and the various forms and rules of debate were common knowledge. Yes, this is true. Debate and watching people skilled at argumentative discussion used to be a popular form of entertainment. Then, during the cultural revolution of the 1960s, the best or the "stars of debate" all sided with the youth culture and not the establishment. That then triggered the removal of debate from educations, from entertainment, and from public life. Now, decades later we have the situation that groups of adults cannot form without conflicts and arguments that drive the community creation aspects away. We have created a culture that cannot communicate, because we have stopped teaching basic oral conflict negotiation of any form.
I did debate in the 00s though and my experience differed - it was already a highly technical affair that didn’t really require strong communication skills, but rather was more about playing logic tricks to be technically “correct” and saying so much that your opponent couldn’t counter all of it during rebuttals. That was enough to get me into the final playoffs at the national championships, and to this day I’ve been told that I focus too much on being “right” rather than being empathetic or persuasive, so debate was not the social panacea that it might have once been.
I went to a school with a debate team in the 2000s, and there were organized national tournaments all the time. And watching social media debaters is still a popular niche past time?
Maybe it's declined since the 50s in favor of football or so on but I'd like to see the numbers.
I really do not think debate team modeled healthy communication. It is mostly about debating as a sport, basically coming up with a sleazy twist argument on the position you do not even believe in. If anything, it makes you greatly prepared to be keyboard warrior of the bad-faith argument kind and teaches you to enjoy it.
I did enjoyed debate team activities btw. The above is what I eventually realized later.
I think people also forget (or don’t even know) that before mobile phones you’d often walk over to someone’s house just to knock on the door to find out if they were in or see what they were doing.
So allied to the lack of dinner parties, there’s fewer reasons to even go to someone’s house any more, you can just text them… or not even bother and check their socials to see what impression of a life they’re presenting today.
