Well, my degree was social science, but not one related to social representations.
I did a tiny bit of reading about social representations recently after first coming across it.
AI summary for convenience.... "Social representations are systems of shared knowledge, beliefs, ideas, and attitudes that groups use to make sense of their world and to communicate with each other. Coined by Serge Moscovici, this social psychological concept explains how individuals and groups develop a common understanding of social objects, like topics, groups, or events, through communication. These representations provide a shared framework that helps establish social order and orient people's understanding of reality"
It sounds to me like it has the potential to be a great way of studying why, for example, GC women are able to understand gender ideology with such clarity and focus on women's rights, child safeguarding and evidence-based healthcare for people who claim a trans identity. A way of helping us to understand how gender ideologues have failed so spectacularly in understanding reality, or (in the alternative) why they are so willing to lie about the reality. It should be part of the way the world identifies dangerous radicals and gains the understanding it needs before it tries to de-radicalize them.
But I fear it is a meaningless nonsensical field of academia that is more often used by gender ideologues to "explain" why men can be women and actual women don't deserve rights.
I'd love to know a bit more. I don;t really have time to go into massive detail, but I'll love to have a better insight into the field and the thinking of most people in it.
