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.

    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?

      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.

        At the very least it makes a good exercise in questioning facts to make sure you are not coming to faulty conclusions by misunderstanding.

          I dont think we need to tread so lightly around this topic, since we already know that brain mass does not directly tie to intelligence from the simple fact that women have smaller brains on average but are not less mentally capable than men.

          Nobody arguing or even just reading this in good faith would try to frame this as women being mentally inferior.

    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.

      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

        My two eyes see slightly different color. Noticed this years ago when looking at a florescent ceiling light with my eyes relaxed such that I was seeing a double image. The two images of the light were a slightly different color.

        I’m a dude.

          I would really like to see a study on that. Take a color then slowly remove the contrast and ask when the change is discernible. Take a color then slowly transition to another color and ask the same question. Maybe do that with a few hundred people of both sexes and record the differences.

          But it’ll have to take into account where people are from. In Northern countries for example, it wouldn’t surprise me if the difference between blues and whites is much more prominent than reds (snow vs not snow). Or for those living in the jungle all their lives, or those living in cities all their lives, and so on. I’m sure there’ll be obvious differences depending on origin and sex.

            There’s definitely studies on it. I don’t know how they measure them, but it’s all about the number and type of cones in your eyes because there are a few different types that see different colors. This is why tigers are orange - because their prey lack the cones that see red, so the tigers look like the rest of the background foliage.

      This reminds me of my wife and I arguing over whether my shorts were grey or brown, she asks her friends and she just says “oh those, they are taupe”. Which essentially means my wife won that argument.

      You are literally charged more for insurance for being a man in the US because men are, observably and on average, worse drivers than women.

        Yes, but to be more exact, men get in more expensive accidents, and women get into more frequent cheaper accidents. I assume it has to do more with risk taking.

          Pretty much. Men speed more for example and drive under the influence more often. High mortality risk on those.

          Women however tend to be a bit more distracted when driving; they use their phones more often behind the wheel for example. There’s also particular situations that simply happen more to women. I.e. they go grocery shopping and are distracted by the kids in the back seat and hit another car or object in the busy parking lot.

          That’s also why innovations like backup cameras and parking sensors are great at reducing those sorts of accidents. But still: tell the wife to put the phones away if she’s driving. For everyone else’s safety too.

    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.

        Yes, absolutely. But as I said, it’s probably not as clear cut as whether you’re XX or XY, because there are other factors that can also impact hormone levels and sensitivity to hormones

    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

      Maybe, and I’m not a biologist or an expert on evolution, so take my uninformed opinion with a big ol’ chunk of salt, but I feel like what you’re describing is more cultural than biological. Like, generally women just play video games (at least online competitive ones where there’s interaction between players, like the ones you’re describing) less than men, because those kinds of video games are sort of a hellhole for women. So in general, their eyes probably aren’t attuned to things like aliasing and digital sniper glints because that’s not something they experience often, not necessarily because their brains aren’t as well equipped to recognize those things.

      hunting is just an extension of fighting, sooo…

      realistically, i think it’s probably a little more fundamental than hunting or something, and more to do with the fact that men are generally more muscular, stronger, taller, and probably faster as well. So it’s probably just a general evolutionary advantage to benefit those capabilities. For things like hunting, etc.

        I am not trying to nitpick you here but I actually think this is a really important assumption to examine precisely because it is a very popular association (forming an unquestionable triangle of “hunting” “war” and “masculinity”) that we treat as unquestionable common sense.

        From my very limited experience with hunting it is nothing like fighting? The entire mindset, physical approach and experience of hunting is almost the polar opposite to fighting other humans, I think one of the only really compelling similarities between “hunting” and “fighting” is that they both involve violence, but the mindset of a fighter is one where the focus is ON fighting where the mindset of a hunter is on the wholistic process of hunting, killing and processing an animal so nothing is wasted and so the landscape from which the hunter takes is not irrevocably harmed.

        The kinds of things that occupy the mind of a hunter are maybe much closer to a polar opposite to most of the mindset and pyschology of fighting and war than we assume superficially. Hunting is a participation in an ecosystem which requires a nuanced deep view based in empathy and practiced understanding, fighting is just about hurting people and being more violent than the other person. It isnt about understanding and sustainably harvesting, it is about eliminating another.

        Just because they both involve weapons doesnt actually mean they have much if anything in common in my opinion.

        Could be as simple as humans get so many neurons and need to allocate them across total set of stuff needed for life.

        Women need to devote a good % of those to pregnancy mode, while men just have normal mode.

        Therefore some functions may have to deal with reduced neuron allocations, because the ‘missing’ ones are required elsewhere.

        Obviously a simplification of things, but with only one way of needing to be men optimize to a different configuration with a different allocation of neurons to match.

          this is definitely the simplest, and probably most likely, though possibly not super accurate answer.

    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.

      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.

        It’s not really a backup X. In any given cell in a woman’s body, one of the X chromosomes has been inactivated into something called a Barr body. The remaining X chromosome is then the active one.

        Women carriers of the gene defect for protan (causing protanopia in males) exhibit Schmidt’s Sign, an abnormal insensitivity to long wavelengths (red light). This is due to the highly skewed L:M cone ratio caused by the defective gene.

        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.

      No, though brain physiology does respond to hormonal shifts.

      This doesn’t invalidate trans folks. No one says they are physically completely equal to cis people. It just doesn’t matter.

      I must assume this was said in bad faith, if so, stop.
