I do not think the purpose of "gendered expectations" is to say that all "white males" behave this way and that other types of people do not. It is not meant to be predictive. As you point out, many people have these traits and there is interesting research finding correlation between behavioral traits and biological factors.

Instead, gendered expectations is about behavior that a society/environment deem acceptable for a certain type of person. That is, it is more acceptable for a man to behave in a loud and assertive manner.

Your final point really rung true with me. It is a great example of how environments encourage, or even require, that type of behavior. I can recall many times that I have been in a meeting and had anxiety that I couldn't get my point across because someone else was interrupting more effectively. And if I don't interrupt at the right time, I get spoken over and eventually the topic moves on.

Know that in those environments, you're not the only person in the room feeling that way. And for the less assertive people or those who think it is inappropriate to interrupt others, they get even less opportunities to speak up. It seems like that is the status quo for so many discussions and I have to wonder, is there a better way?
