I have seen a printed 'leaflet' given to me by a friend on the subject of unconscious bias, Inclusivity etc. It was very informative, well-written and concise.
It made me realise something which I already knew anyway, that I, along with others, have this bias to some degree or other.
I don't think it's necessary to hold a Course. An online Paper on the matter is sufficient. Anyone with a modicum of intelligence could understand the one I read. It's a waste of resources.
There's a lot of evidence that unconscious bias training doesn't work. It was popular in the mid teens (2013-18) and rolled out throughout many government departments, but research indicates it doesn't change behaviour and some research indicates it just helps people conceal their bias a bit better — so they still discriminate, just discriminate in a way that is less easy to pin down and do something about. Perhaps they don't say racist things about colleagues, but they find other more subtle ways of expressing their racism.
I've read an article about how unconscious bias training can make people with bias feel even more resentment and animosity because the training, when poorly conducted, can leave people feeling guilty and shamed for their bias. Unfortunately I'm not able to locate that particular article but if you google 'why doesn't unconscious bias training work?' you'll find lots of articles.
