It's easy to be snobbish about it if you want to point out that it's not a scientific study published in a journal with Very Serious People as gatekeepers... ...but I think this one is onto something, and I wouldn't be surprised to see significant correlations between the behaviours described and social class as defined by relatively recent work e.g. https://journals.sagepub.com/doi/pdf/10.1177/0038038513481128 https://journals.sagepub.com/doi/pdf/10.1177/003803851348112... (The above takes into account social and cultural activities and classifies Brits as elite, established middle class, technical middle class, new affluent workers, traditional working class, emergent service workers, precariat) The BBC used to have an interactive version of the above, but it's broken (again!) - if you report it they'll probably fix https://www.bbc.co.uk/news/magazine-22000973 https://www.bbc.co.uk/news/magazine-22000973
