Valid questions. No, I’m no professional, nor have I studied in this field. This is personal opinion based on my own anecdotal experiences.

I suspect there probably is a more rigorous exploration of this idea somewhere, we can’t be the first people to notice the commonalities. But I am not qualified to process or judge the studies, and I do know that social science work is particularly challenging due to the difficulties of cramming people into laboratories and performing conclusive experimentation upon them.
