Testosterone is a good example where just because there is a M/F differences does not mean that all M have more Testosterone than all F. So, within the Male designation there is a range of how Male someone is.
You see, "high" and "low" testosterone does make sense on a continuum. It is plausible to think that incremental jumps on this scale could mean incrementally different predictions. I could see how there could be some noisiness and complication, but that doesn't mean the construct lacks competitive utility.
However, I don't think the researchers would accept testosterone as an adequate spectrum to contain human sex. So what spectrum is proposed, then? I have difficulty imagining, because I think having a spectrum of Maleness vs Femaleness would be antithetical to what the researchers want.
