Human Height is not Bimodal

I don't find that article convincing, the mean difference is very, very close to the combined standard deviations. Some men haven't reached their full height by 20, I'd expect that to be enough to tip it into officially bimodal. I also don't understand why they didn't present the SD from the data, it looks like they had to compute it to make it "more normal" which they wouldn't have had to do it they'd recognised it was two normal sub groups.

Any estimates and projections would be more accurate if separated by sex, so why group them? We are moving towards recognising women in medical research, this would be a step back.

That has absolutely nothing to do with sex not being binary though, as we don't use height to "assign" sex to someone. The sex comes first. There is also no reason to say sex is bimodal, that just shows that someone doesn't realise there needs to be a measure/units along the x axis.

But when people talk about large vs small gamete size they aren't talking about the size distribution of a particular gamete type

Are any sperm bigger than any eggs?

The large and small descriptions of gametes are a comparison between the size of one type of gamete and the other

I have always referred to my Chihuahua as a ratdog I am certain that rat-chihuahua is spectrum, with him falling more towards the rat end in many ways.

I may have to rethink some stuff.

I think power differentials eg grip strength is so important and not widely recognised in an easy to understand way.

I was looking the other day (but couldn’t find clear graphics) on if you lined up 100 men and 100 women by grip strength, on average where would they stand in the line?

Looking at the graph above I guess about 85% of all men are stronger than all women. Does that sound about right?

This is a weird OP. I am a woman who is 6ft 1 and I am taller than most men. I am an absolute outlier though- seeing a woman taller than me is so rare I am startled when it happens but I pass dozens of men every day who are taller than me.

Men as a sex class are taller than women as a sex class. I’m not sure what needs to be analysed further.

I do think we need to read about doggit. It is always useful.

yep. a gallon of paint, average sized domestic cat, and a smallish microwave oven all weigh roughly the same amount. but are quite different to each other when you look closely.

Exciting stuff.

Tall women are not men.
Short men are not women.
HTH.

I don't understand the premise of the thread at all.

averagely tall women are about the same height as short men but shorter than averagely tall men.

tall women are about the same height as averagely tall men, but shorter than tall men.

etc etc etc

e.g. basketball is a sport that strongly favours tall players, but the extent of this varies strongly by position, eg freakish athleticism/skill is non-negotiable for point guards, height a huge bonus. for centres it's the other way round. most other positions are somewhere in-between.

here are the heights of the male and female** 2024 Olympic rosters.

male: 6'2", 6'3", 6'4", 6'4", 6'5", 6'5", 6'8", 6'9", 6'9", 6'9", 6'10", 7'0", average 6'9".

women: 5'9", 5'10", 5'11", 6'0", 6'1", 6'2", 6'3", 6'4", 6'4", 6'5", 6'6", 6'9", average 6'2".

'** it's unconfirmed but the tallest member of the women's team, Britney Griner, is likely a DSD male.

the distribution for the whole adult population will be Bimodal if the difference in the means is large compared to the variation within each sex.
This is the case for example in gamete size or testosterone levels.

Gamete size is not bimodal. There is no distribution. Big or small - those are your options. And as well as the sizes being binary, they are totally different types of cell.

I would think this refutes the idea that the famous tall swimmer with big hands is why men are allowed in women’s toilets.

Height is not bimodal, so some women are tall doesn’t mean that sex is a spectrum.

and stuff.

And the poster seemed to have read the paradox institute article I posted to explain why sex is binary and not bimodal and not grasped what the article was saying.

Plus the poster failed to grasp how humans don’t chart on an axis of more male to less male and more female to less female. I think they genuinely think some male people are more ‘male’ than others so that they believe the whole bimodal thing works….

here is the thread and the post at 17.23 and I think height was mentioned further along the discussion.

But the OP (who is not the poster in question talking about sex being bimodal) didn’t want the thread derailed further so OP has done the right thing and not posted the clarification on the thread.

Indeed not, and that is in fact a bimodal distribution.

Genderists like to say human sex is bimodal. As far as I know, no-one has yet identified the sperg or the spegg gametes, so sex is binary.

Maybe binary now identifies as bimodal, leaving bimodal no choice but to identify as a blended distribution (or some other made-up identity)?

Have another of my favourite pictures :)

And the good news is that entitled men will still be able to fit on the toilets in womens cubicles. Phew, thought for a minute there we might have to have them all raised up on blocks or something so those long male legs would be comfy.🤓

I believe that the OP might have been inspired by a male poster posting on the AMA thread that sex was bimodal.
