one thing is just mentally which hand one prefers to use
the other is physically reworking the entire body, you can't compare the two

All australians are vertically flipped.
Their circadian rhythm is also fucked up 180°.

Because being left-handed has nothing to do with your brain being reversed. The actual reason why isn't know, we also don't know why 90% of humanity is right handed.

>>16936680
It's not mental, otherwise there would be an even split between left and right. There's a physical reason nearly everyone is right-handed.

>>16936690
It's developmental. Children see people do things with their right hands so they do things with their right hands during early childhood development. So prioritizing use of the right hand becomes ingrained in the physical ability of the child as they grow older. Similarly, cilantro has a mild soapy flavor. But if someone focuses on the soapy flavor the first time they try cilantro, then that becomes the taste that they are expecting and the taste they focus on. Over time this ingrains the soapy taste.

By that logic 50% of the population should be gay.

>>16937036
That's mostly untrue, why post such crap? Traits like handedness are complex with no single cause. However studies have shown that it is mostly due to genetics and multiple genes involved with some influence of culture.

They do, but it's rare.

Doctor Who must have been ambidextrous.

Ambidextrous people make up 1% of the world's population, Situs inversus 0.01% of the population

Studies have shown that left-handed individuals tend to have a more developed right brain hemisphere, which is associated with creativity and artistic abilities.

Several of the most famous and influential physicists in history were left-handed, including Albert Einstein, Marie Curie, Isaac Newton, and Nikola Tesla. Their left-handedness is often associated with the creative, divergent thinking necessary for their groundbreaking contributions to quantum theory, relativity, and electricity.

I'm soooo relieved I'm left-handed now.

>Ambidextrous people make up 1% of the world's population
That sounds like an incorrect statistic to me, 1% is still lot of people. True ambidexterity is shockingly rare, I've certainly never met anyone with it.

>>16937078
You are probably right but it's hard to get accurate numbers for innate ambidexterity. Some of that reason is societal, left handed people live in an environment surrounded by right handed tools and devices so they end up having to use their right hand. This gives the 'illusion' of being ambidextrous when instead it's something they've learned to do.

Little known fact, there's actually an even rarer trait than ambidexterity called 'cross dominance'. That is where a person will naturally use one hand for a certain task, but the other for something else even if it's closely related and they struggle to use the other hand for that task. They are neither left or right handed, but both.

>>16937036
Bullshit. Prehistoric cave paintings showing hunters using weapons and hand impressions on walls all depict them using their right hand. It's not a recent development thing.

There are various competing explanation, none have established a clear dominance in terms of overwhelming evidence.

These are all publications favoring the hypothesis that early development of the vestibular organs and their interconnectedness with the central nervous system lead to a Lateralized cortex, i.e., the orientation of your inner ear while you are still in your mothers belly biases stimulating of one side of cortex with vestibular (balance related) signals and therefore the closely related motor system also gets biased, hence handedness development.

Mono Cygotic twins, i.e., the most perfect kind of clones you could ever get, and therefore genetically equal, are often discordant for handedness, one being left-handed while the other is right-handed, if they lie back to back, i.e one was biased one way while the other was biased the other way.
If both lie in the same direction they appear with the sane handedness.

However, large samples do not follow this trend.
So it seems reasonable and has some evidence in favor of it, but there is more to it than just prenatal bias.

Maybe early life experience can still change laterality or there are multiple systems competing? -it is unclear.

The next question is, why a Lateralized brain is useful, or what it us useful for.

Thanks ChatGPT.

I wrote that myself, -in fact I coauthored one of those publications.

Hatred of new technology dates back to the very first programming languages. People used to say high-level languages like C++ weren't 'true' coding. Well, go ahead—try writing Blender in a low-level language; I’d love to see that.

It was the same story in the early 2000s with the Internet—people claimed it wasn't 'true.' The problem with these people is a total lack of understanding that technology is an inevitable tool of the times. They resist it out of a sense of retrograde masochism—desperately clinging to their 'old-school' skills—or simply because they don't know how to use the new tools.

An LLM is a mirror. If you're a degenerate without AI, AI isn't going to save you. You can be a degenerate just fine without it. By the way, I’ve heard that closed sects are also famously against new technologies.

>>16937602
This is a deconstruction of the bias and propaganda used to demonize AI. AI isn't a threat to society; it’s a threat to the establishment. It threatens their monopoly on knowledge. As for ethics and regulation—AI is just a tool. The responsibility lies solely with the person using it and how they choose to do so.

>>16937612
In an infantile society—much like a psych ward—they hide the scissors so no one gets hurt. The crusade against AI technology is built on a presumption of imbecility and guilt, regulated by those who fancy themselves the masters of the ward.

>>16937615
In a society of degenerates, people fight technology instead of using it. When there is no ethics and no education, this reaction is entirely predictable.

>>16937549
So that's why they read like schizo-babble?

>>16937630
Exactly as predicted. First, you cry 'ChatGPT' because you can't fathom someone being more articulate than you. Then, when you realize it's a human expert using his brain, you call it 'schizo-babble' because the level of complexity exceeds your room-temp IQ.

You’re the perfect exhibit for the 'psych ward' analogy—screaming at the scissors because you’re terrified of anyone who knows how to cut.

>>16937650
One last thing: those without brains will keep picking at the dirt with a teaspoon, calling progress 'schizo-babble.' Perhaps those who actually have them will finally start learning how to operate the excavator.

what's the tl;dr for normies?

I'm left-footed and it's stupid.

>>16937719
As far as I can tell all those paper say is that the brain is lateralized, which means the left and right sides of the brain do different things. That's common knowledge. The (unproven) theory is that then there is a part of the brain in the left hemisphere, possibly related to our use of tools, which means humans will always their right hands to do stuff. Even if this is the main reason why none of those links can explain why then left handed people exist.
