Historians and “historians”

This post has very little to do with language.
My opinion of Emma Dabiri, mentioned in my last post, has nose-dived since I wrote that. I’ve now watched the last of the series of ‘Britain’s Lost Masterpieces’, which featured a painting found at Hospitalfield, an arts centre near Arbroath. For a start, she consistently mispronounced its name, adding a final -s which is totally unwarranted. But unforgivably, she said that it was built as a hospital attached to the Benedictine Abbey of Arbroath, but that “the monks were chased away by Henry VIII”.
Ms Dabiri calls herself (or at least she is billed as) a ‘social historian’. To me, this means that she has studied history, and later specialized in social history, having gained a solid grounding in the general subject. She may be Irish, and so not have gone through the British education system, but if she is to make programmes about British history, then surely it behoves her to gain some knowledge of the subject before making such crass errors on screen. I’m sure that 5 million Scots will agree with me.
It is perhaps symptomatic of British education at the moment that noone on the production team spotted the error, and got her to correct it.
