Sorry, I am only up to birdsfootrefoil ‘s post about ‘lived experience’
I genuinely do not think this is meant to be anecdote over objective evidence but giving voice to groups who are usually marginalised and would not normally have a voice.
So traditionally social scientists, anthropologists, researchers would come along and do their research on a community or group, without involving that group in the research or how findings were interpreted.
So I think - and I may be wrong - that the phrase lived experience is in part an ethical commitment to involve the people who are being researched, legislated for, or policy and practice otherwise created around and avoid further marginalising groups.
I am tired so cannot think of a good example but I am thinking of work which might do qualitative research with women living with disability. Every one of those women will offer insights into the lives experience of disability, their interactions with services and the judgements, barriers and stigma which they face.
Those experiences should not be the beginning and end of research but if you want to design policy which works for people, ‘lived experience’ is pretty key to understanding the issues they face.
Of course there are more ethical issues about whose voices you hear, how they are recruited, how what they say is used - but qualitative research has a place.
Sorry that is nothing to do with queer theory.
