The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.

The eyes have it: Men do see things differently to women

The way that the visual centers of men and women's brains works is different, finds new research published in BioMed Central's open access journal Biology of Sex Differences. Men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors.

Hmm... Men are more excited through visuals while women are more excited by touch.

I'm not actually sure if you are joking.

I need to see your clearance from at least one of three or four three letter agencies before I can tell you the real answer.

Men’s vision is movement based, just like T-rex.

Fine detail and rapidly moving stimuli ( ͡° ͜ʖ ͡°)

... Men are also ~20% larger than women on average. Is this count standardized by size of the person?

[–] L0rdMathias 26 points 2 months ago* (last edited 2 months ago)

Does that include brain size? I mean yeah the total sum of all size comparisons is 20% larger, but like piece per piece that ain't remotely true (see boobs for an example that defies the total average).

I'm curious about this. They say that it's related to in utero exposure to androgens, which means it's probably not as clear cut as XX vs XY, because intersex folk and folk with atypical hormonal exposure (such as fraternal twins of different sexes, with a shared placenta) experience different levels of exposure, and different reactions to that exposure.

[–] [email protected] 13 points 2 months ago* (last edited 2 months ago) (1 children)

But most things human are regulated by hormones, because of genes.

Whatever it does, it doesn't seem to help with colors.

Literally under the headline.

Brain one way, but other brain other way. Chemical stuff is making brain stuff happen. Makes see different.

My wife (presenting me with three identical carpet samples): "Do you like grey with a hint of blue, grey with a hint of pink or grey with a hint of yellow?"

Me: "Trick question?"

Anecdotal proof time:

My dad's truck.

Me, my brother, brothers' friend and brothers' friends' sister, all XY, all see a greenish gray truck.

My mother, sister-in-law, brothers' friends' wife, all XX, all see a dark green truck.

It's the blue/yellow dress all over again.

[–] [email protected] 14 points 2 months ago (5 children)

So, for XX folk, the increased colour differentiation comes from fact they carry two sets of genes that encode for colour detection, and because they don't encode identically, each set creates a ever so slightly different perception of colour. And when you get two similar, but non identical perceptions of colour, you see more hues

ok so, here's my theory. The obvious answer here is that this is obviously "for hunting" or something. But evolution doesn't really work that way.

So my take on this is that this is actually an evolutionary adaptation to the different structure of the male body, as well as it's general abilities, and how they have been used throughout humanity. If men are generally stronger, taller, and faster runners, wouldn't it make sense that the visual processing would be adapted to be more responsive to these use cases?

this seems like the only realistic answer to me. Something about men must be different enough, or at the very least, have been used differently enough at some point in time for a long enough period of time, that it has to have been an evolutionary adaptation.

women are better at discriminating between colors.

Well I'm red-green colorblind so I never stood a chance anyway. If it isn't in a box of 8 crayons/markers, I don't attempt to use that color's name generally, cuz I will never pick the right shade. All the fuschias, magentas, maroons, burnt siennas, teals, cyans, etc. of the world can fuck off.

[–] [email protected] 19 points 2 months ago (4 children)

Isn't colorblindness almost exclusively found in males too?

Probably oversimplifying, but it's something about the mutation being on the X chromosome, meaning women have a backup X and men don't.

[–] [email protected] 22 points 2 months ago* (last edited 2 months ago)

It is possible for someone with two X chromosomes to still be colorblind, but since this gene is recessice you have to have the mutation on both chromosomes, which makes it way more rare.

Does this mean the visual center is 25% larger or that the configuration of cells is different? If it is larger where are are women's brains larger then men's brains?

[–] L0rdMathias 19 points 2 months ago (2 children)

It means there are 25% more, but neurons aren't the only thing the brain is made of. Idk how much of a size difference, if any, this makes. Considering how sensitive lips and fingers are compared to equal sized parts of your skin in other areas, there might be a similar situation of just having a lot of space in the total structure for extra neurons. It could be a small increase in size, it could have no impact on size, more studies required.

I've seen multiple people suggest hunting and get correctly told thats inaccurate

But would war fighting, or just fighting in general what with our aggression n shit help explain it?

The only times I've noticed this discrepancy in life are when hunting with women of playing competitive FPS games with my wife watching. I'll regularly see and react to things they don't, and are shocked when I shoot the sniper out of the tree on the other side of the map because yes, I did see him and I'm not crazy when I say I see shit flicker gdi

Aliasing also bothers me more than any woman I know, and everyone I know who hates it as much as me is a man
