Every person who makes the claim that "Sex is a bimodal distribution" is never able to actual say what it is a bimodal distribution of. That is because the people who make such a claim are incapable of independent thought.

Sex *has* a bimodal distribution. It *is* a bimodal variable.

1. Please tell me how to measure this variable. 2. For bonus points, show a peer reviewed paper where a biologist has measured this variable *for real* in a population and a bimodal distribution of sex has resulted. 3. If you cannot do this, would you reconsider your position?

How you measure it depends on what purpose you're determining it for. (And I already linked you one. Would you like another?)

The purpose is to show sex forms a bimodal distribution when measured and plotted. Can you show anyone who has ever done this with real data? Or is it just ideological stupidity?

I think you are imagining a one-dimensional variable that has two modes, which is a simple case of something being "bimodal", but not its definition. Bimodal just means having two modes. Those modes could be in conceptually 1-dimensional or N-dimensional, qualitative or quantitative.

Saying "sex is bimodal" is describing, qualitatively, that in a population (of, say, humans), there are two places in the distribution that are more common than all the others. Stressing "bimodal" rather than "binary" indicates that although those two places are more common there are others, too.

There are no measurements that lead to the conclusion that sex is bimodal - no matter how you formulate that.

Kathryn has failed to say why we call the brown birds female. She knows the answer but is too intellectually dishonest to admit that, so she has been blustering.

Do we call the brown birds female? Because here, you make it clear that's an error. bsky.app/profile/quac...

Yeah, tons of them. I already have. But there are thousands of sex-linked traits, so . . . which ones would you like to see plotted?

"vast" is non-responsive. i want specifics. also i have no background at all i don't give much of a shit about biology beyond my own personal interest in mine continuing to function, and occasionally when TERFs use it as a weapon.

Actually, in some species of bird, it’s not even bimodal. White-throated sparrows have four peaks, ruffs have five…

First, how ‘bout you show the other person in the thread supposedly agreeing with you? I’m pretty sure you’re gonna come up with a reason why anything I show you doesn’t count, but I promise that if you have a non-imaginary friend in the thread, I’ll acknowledge it.

(Although research on ruffs has only just shown the fifth, and the faeder males are about 1% of the population, so I don’t know how that affects the distribution—three big peaks and a small one?

Yes. I would love an actual chart that shows all these peaks. Note: we will not get one.

You haven't demonstrated that yet unless getting basic facts wrong and making clearly erroneous conclusions is... independent thought
