I may come back and review some more of the literature, because it really is an interesting topic.
Your last citation there actually seems relevant to OP, since they’re asking about this difference in how they feel around other men vs in mixed groups.
It would be useful to know if there are indeed more studies like this that maybe show that the stereotype (which aren’t inherently wrong or negative) is too vague, and i would like to know the specifics, maybe the stereotype only holds in male-dominant spaces. Or (and I think I’ve read this) when males are primed to act more masculine.
