Another forced brat here. I think we notice the attitudes to different accents and dialects a lot because we both experience it and notice others behaviour around them.
As a result I have a weird Anglo-Scots accent. Scots say I have an English accent, English say it’s Scots.
I also have to resist doing something I later learned actually has a name - accommodating. Slipping into the accent of whoever you’re talking to.
And it doesn’t have to be an accent of an area I’ve lived in either - which really confuses people! But any strong accent has an effect on me.
Op there are LOADS of studies on this stuff if you’re interested? Sounds like you’re interested in the sociolinguistic aspect.
It’s a fascinating subject, and definitely not a new thing at all. Even monarchs in the past came under scrutiny even criticism for their accents and dialect.
So did shakespeare and many other writers.
My parents have broad weegie accents and they are working class people but they’re far from stupid. Dysfunctional yes but not stupid!
I’ve cousins who’ve ended up being raised in other parts of Scotland or other countries and so sometimes have “posher” accents but they’re no more intelligent or educated than the cousins with broad weegie accents 2 of whom are teachers and 1 a lecturer.
I also have the pleasure of having a lovely friend who is EXTREMELY posh, went to best schools etc - even HE would and does describe himself as “astonishingly thick considering” he barely managed 3 GCSEs.
You can’t tell from someone’s accent any more.
I lived at one point in a VERY posh part of the country - I’m talking royalty, Major celebs living in the area... worked in a shop there (was only living there because ex stationed there) all the locals very posh accents and of course a variety of educational levels - as there are anywhere.
But... very little snobbery issues there.
