My wife (equalist, not feminist) is a lecturer in Psychology and one of her modules is on Toxic Masculinity. She asked me for my input on the subject and to my surprise the subject matter seemed reasonable and unquestionable. So for the module in 2017 she didn't change it and taught it like normal.

After reading here it seems like the notion is debunked, but no one is able to point to how/why it is.

My wife is now in the process of evaluating the lectures on that module for this year and I thought I could pass on some relevant evidence to help shape her lectures.

Could anyone point me in a direction of academic level material that I could pass on to show her?

Thanks.
