Confidently incorrect is the default with these people. I spend most of my time with family aggressively correcting misinformation about my field and related ones. They will die earlier thinking they know more because of Youtube. Getting them to stop taking bad health advice and mystery joint injections from a fucking chiropractor is the latest battle.
The impression of legitimacy enjoyed by chiropractic is too damn high. I was well into my 20s before I ever heard a single word about it being pseudoscience. Walking around (usually on people’s fucking spines) calling themselves doctors, I absolutely believed it was just some sub-variety of physiotherapy, which I guess is the point. In the whole universe of alternative medicine, I think that has to be the practice which has most effectively disguised itself as conventional medicine. It’s gross.
Darn that science, keep that liberal where it belongs, in the humanities.
People who see gender as a F or M binary in 2025 are willingly ignorant to the bone.
Note how they always enshrine gender in biology, but then make all kinds of non-biological statements about what gender is.
“XX is woman”/“Large gametes is woman”/“can conceive is woman”
And then they’ll say
“Women aren’t as aggressive”, “women are more emotional”, “women like being in the home more”, “those are women’s clothes”, etc.
The only reason it’s so important for it to be biological is because of how it punishes gender non-conformity and makes the lives of trans people hell. Like it isn’t ideologically consistent and they know that. They just don’t care. If it was just about genitals or chromosomes, then why is it that gender dictates all these social things about us? The only reason to root gender in how you were born is to ensure gender roles are as rigid and immutable as possible.
how it punishes
gendernon-conformityFit the mold or die. Always the same.
Without a purity test how can I tell which members of the tribe are loyal and which might betray me?

Yes, there are many species that have more than 2 sexes. Those are decided by scientific consensus.
But sex is ultimately a category to describe the process of reproduction. By definition, this is exclusionary. It’s why conservatives fumble so much when trying to describe sex in terms of actual definitions. Inherently, it is not possible to fit every person into a table of 2 columns in that way. Sex is not a binary because human beings are not binary. There is an incredible amount of variation in our bodies.
Relating to humans?
Yes but they are mutations (e. g. XXY, XXX, etc.) that often give rise to numerous biological problems or death.I don’t know if there are species that require more than two sexes to propagate. I never head of them.
You are vastly underestimating the prevalence of chromosomal variations. They are common, especially among cis women.
I like the way you phrased that at the end. Sexes are categories that relate exclusively to the concept of progeny. If you’re not able to reproduce, you’re already kind of excluded from the sex binary. If we break the human concept of sex down to its constituent parts, it is just “can procreate”. The categories are useful in some contexts, but to state them as universal or to try and extrapolate them so widely is significantly disruptive and unhelpful. Humans are and always have been more than our reproductive anatomy. Your doctor and anyone you want to reproduce with are really the only people who need to know whether you fit into either category.
“It’s basic biology” mfs when advanced biology
it is basic biology, ie biology simplified to teach a kid in middle school. the thing is sciences don’t stop at middle school level. a lot of university education is about clarifying that things you learned before were simplified to the point that they’re practically useless if not outright wrong.
Light travels in straight lines, next year its a wave and then its particles. What you said isso true about uni rethreading.
Tap for spoiler
You don’t technically need particles!
Meet me next week for more hot physics takes nobody needed.
I think a lot of these XX XY “only two genders” people aren’t just dunning Kruger, they’re transphobic idiots with an agenda. So even if they had the science and knowledge it wouldn’t matter because they’re pushing their hateful stupid agenda, facts and logic be damned. They don’t care, they just want to rationalize hating us trans people because we make them uncomfy.
Tell us what the 3rd gender is please.
~95% of all animals in the world, including humans, are gonochoric, have only 2 sexes.
Turner syndrome and klinfelter syndrome are exatly that, syndromes
Gender is not sex. Have you ever, in good faith, talked to a trans person? Have you ever, in good faith, talked to an intersex person?
I keep hearing this. If gender is not sex than gender is not real, you can be whatever you want whenever you want, right?
Still, if a dudes is a dude it’s a he, if a woman is a woman it’s a she.
The only time I would actually bother ask someone what they like to be called is if they have an intersex condition. That’s it.
Have you ever, in good faith, talked to a trans person?
Yes, it was the exactly stereotypical “call me mam” hairy dude. Yeah, that’s never gonna happen. First time in my life I told someone to never talk with me and pretend I don’t exist. I don’t want to interact with these kind of lunatics.
Have you ever, in good faith, talked to an intersex person?
No but I would love too, that seems genuinely interesting. I’d have so many questions to ask
If gender is not sex than gender is not real, you can be whatever you want whenever you want, right?
How does “you can chose” make something not real? Also, it doesn’t appear to be a conscious effort to be trans. Do you really think trans people go through all that just for the fun of it?
Still, if a dudes is a dude it’s a he, if a woman is a woman it’s a she.
And if a women is not a woman and starts HRT and everything, he’s a dude. You’re exactly right!
The only time I would actually bother ask someone what they like to be called is if they have an intersex condition. That’s it.
Can you tell that just by looking at people?
Yes, it was the exactly stereotypical “call me mam” hairy dude.
What if it was someone who visually fit in your expectation? Would you treat them with basic respect? Can you tell me the sex of each of those people?


No but I would love too, that seems genuinely interesting. I’d have so many questions to ask
Wouldn’t it be interesting to talk to a trans person, too? Understand their perspective? Maybe you already met someone intersex but called them slurs and walked off because you thought they might be trans.
Your baseless hate for trans people only brings evil into this world. Maybe try giving people a chance. We’re all human.
Do you really think trans people go through all that just for the fun of it? I honestly think they have mental problems that won’t be solved by mutilating themselves. It’s not me to make that decision for them and it’s their body but I try to keep myself as far away as possible.
And if a women is not a woman and starts HRT and everything, he’s a dude.
What do you mean a woman is not a woman?
Can you tell that just by looking at people?
Most likely not, but by interacting with people, yes.
Can you tell me the sex of each of those people?
Only from faces? Most likely not. First pic looks like a woman, second like a man, 3rd pic that dude might be a woman, 4th the dude is a woman and 5th I have no damn idea
called them slurs
I don’t call people slurs mate, I just avoid interaction.
Reading the discussions and some of the disagreements, a correction is needed to be more precise.
Some XX people will be Assigned Male At Birth. Some XY people will be Assigned Female At Birth.
Some XX people live their entire lives as men without ever knowing otherwise, and the same happens with XY individuals living as women. Even having children won’t reveal the apparent discrepancy, unless they need certain tests done.
Critically thinking now, how strong is the evidence here?
Those are two real medical diagnoses - Swyer syndrome or XY gonadal dysgenesis for XY women (occurs in about 1:100000 women) and de la Chapelle syndrome or XX male syndrome for XX men (occurs in about 1:20000 to 1:30000 men)
Here is a NORD report on Swyer syndrome, as well as the original article on de la Chapelle syndrome: 1.https://rarediseases.org/rare-diseases/swyer-syndrome/ 2.https://pmc.ncbi.nlm.nih.gov/articles/PMC1762158/
A person’s biological sex usually refers to their status as female or male depending on their chromosomes, reproductive organs, and other characteristics. Chromosomes are tightly packed DNA, or molecules that contain the genetic instructions for the development and functioning of all living things. Humans typically have forty-six chromosomes. Two of those are sex chromosomes that contain instructions for the development and functioning of characteristics related to biological sex, such as reproductive organs. There are two kinds of human sex chromosomes, X and Y. Individuals identified as males tend to have one X and one Y chromosome, while those identified as females tend to have two X chromosomes. However, other people are born with other chromosome combinations, such as XXY, that lead them to develop a mix of characteristics. People who fit that description are often referred to as intersex, a category for people whose bodies do not conform with stereotypical expectations of males or females at birth.
Taken from here
Evidence seems pretty strong to me.
Yeah, and those are malformations and genetical defects that come with a lot of problems.
I don’t know why people glorify them… Also, there is absolutely no way that a man born with XY magically will change it in their lifetime as the posts sugests.
The post suggests that some people with XY chromosomes are assigned female at birth and will live as a woman.
And some people with XX chromosomes are assigned male at birth and will live as a man.
Not that the chromosomes change.This article seems to disagree. But I don’t know much on the subject so I might be misunderstanding.
Also, no matter what the correct answer is, pretending the answer is binary is definitely wrong. Since it’s obviously a lot more complicated.
From the article:
“Girls born with XY chromosomes are genetically boys but for a variety of reasons – mutations in genes that determine sexual development”
And again, they don’t magically become the other sex, that was already determined at birth.
No, not magically, no. You’re right.
Well, to be fair, not magically and not in any other way, it is impossible to change your sex
You’re the only one talking about this. A change can occur without any surgery. Reread the article to understand better, please.
You read the article and you even quoted it. It says how xx people can be men and how xy people can be women. Nobody said anything about any surgery or magic pill that grows a penis or whatever you’re imagining.
Dunning-Kruger reminds me of this one president and his cabinet.
To be fair, a Person with a PhD still can have Dunning-Kruger on other subjects.
Ben Carson is a great Neurosurgeon, but dumbass on politics.
Even Noble Prize winners are surprisingly often affected by this -> wikipedia:Noble disease
You know how a bunch of villains are Dr. So-and-So? I bet it’s dealing with morons talking about your area of expertise that leads to one’s villain era.
Go Stephanie!
While this is very funny, and definitely representative of a sort of ignorance/arrogance commonly found in ideologues - I recently learned that most people talking about the effect have, in fact, been Dunning-Krugering themselves.
Insightful video on the topic.
What most people expect the effect to look like:

What the actual results were:

Yeah, it’s really frustrating and quite ironic that pop culture keeps using this obscure scientific reference, that they don’t really understand in its intended context, to describe something that really ought be plainly said: that we all have a tendency to overinflate our competence. if anything Dunning-Krueger showed that only the most seasoned experts judge themselves modestly. (and even then we’d likely only find their modesty in that particular area of expertise). it’s a commentary on all of us!
But no, people name-drop this research just to dunk on people and feel smugly superior. (and I am glad I agree with the politics of the intellectual in the OP, that means it’s okay and I’m a bit more competent too!) ugh. I cringe every time i read someone say Dunning-Krueger.
PS on your first image, whoever failed to put “phd student” at the trough of that curve fucked up
I agree with Dr. Jey McCreight on the science.
But for determining truth, both sides are wrong here.
Dunning-Kruger is bad, but so is credentialism and appeal to authority.
Many people with PhD’s have had Dunning-Kruger. Someone else mentioned Ben Carson being great at neurosurgery, but not politics.
A PhD doesn’t make you infallible.
I am saying this as someone who is taking graduate-level courses and will be pursuing my PhD. When I’m correct, it’s not because my future PhD causes reality to magically conform to my opinions - it’s because I rigorously looked at the evidence, logic, and formed my own conclusion that better aligns with reality.
Okay but what is good engagement against “follow the science” aside from “I literally DO the science”? Dr. McCreight offered a point and was met with “nuh uh” so at that point it can hardly be called an argument or debate. Do those fallacies honestly matter at that point when one refuses to engage with tangible points of discussion?
