I just wanted to say that you shouldn't be getting downvoted. You've asked a question that isn't editorialised, appears to made in good faith and asks the opinions of others.

You've prompted some very good answers here.

If you’re a fan of the idea, you’re either a nazi or really really ignorant/naive/misinformed.

So I’ll assume the latter and try to briefly explain to you why it’s so bad: people bad, authoritarianism inevitable, results in ‘oops you’re not “human” because you lack/have X, you must die’

Humanity, just like nature, thrives with diversity. Eugenics starts with “getting rid of nasty diseases” but it’s always 1 bad classification of “disease” away from genocide.

WTF kind of question is this?

Is it a thing? OK, yeah? A concept of an idea, maybe.

Is it anything approaching moral, ethical or humane? No.
Nooo.
Nope.
Nuh-uh.

Thanks for coming to my TED talk.

It's impossible for me listen to someone arguing in favor of eugenics without hearing, "we've gotta get rid of those people- you know the ones in talking about, right?" Fuck that noise.

It's always some narcissistic asshole who thinks they're the prototype for a new master race.

Theoretically, to produce the happiest and healthiest humans, yes. In practice, NEVER.

Aside from near inevitable genocide of existing races, that would occur with the excuse of "purification", there would be further discrimination against the "impure" populace. Immediate class division would occur between those who are genetically modified/improved, and those who were conceived naturally, without any scientific intervention.

Companies would only be willing to hire the "improved" humans, and the rest of us will be left to rot in slums.
It would be unrestrained fascism, scientifically endorsed under the guise of "improving humanity". All calls from the impure and insignificant would be ignored, as they would be perceived as obstructing scientific and humanitarian advancement. I believe it would be amongst the greatest humanitarian catastrophes that could occur.

I feel bad that this post is being downvoted, as it is a discussion that needs to occur. Eugenics can be perceived as an advancement to human biology, but when considering human behavior, it would be a rebirth of fascism.

That being said, I would support doctors advising those with genetically linked, debilitating illnesses, not to reproduce. Keyword though, advisement, not mandate.

No. Read dystopian novels like Brave New World and you'll understand why.

Where do you get these questions?

I believe that it exists as a concept. That's what you're asking, right?

It depends... Are we speaking about keeping only tall blonde kids? Or aborting a fetus with 95% Down syndrome? Angelman's? Some other even worse? Stopping a possibility fatal pregnancy? Where do you put the line?

Is "pre implantation diagnostic" eugenics? Future Crispr modifications of human DNA is a whole other level of discussion... related to eugenics, but a can of worms I won't open.

No but I'm all-in on phrenology

Eugenics is mostly associated with selective breeding so that's a no in that regard. I do think modifying our children genetically will become more common place and will be an important part of future off earth colonies.

Like Gattaca?

I do not think people have enough information to even do a good job of it, we'd accidentally make everyone prone to some disease and wipe out humanity, we don't have a great track record with selectively breeding plants and animals. So no.

In the way it has been done ever in real life? Oh hell no. Some vague idea that certain people are worth more than others based only on their looks, and a push to make a better world by making them the only model for humanity?

So no. I don't trust people to use it for good, and if it was somehow used for good, would probably still have unintended disastrous consequences.

We have entire communities for unpopular opinions and shitposting, yet you chose to post here on ML?

No, since it would require draconian control over people's lives.

Yea. It exists and is a terrible idea. Like it's a creepy ideology that rears its head in too many places.

Selective breeding of humans is not and never was a good idea. It comes with forced sterilisation, marriage bans, stigmatisation of characteristics contributing to naturally occuring diversity, supremacist thinking and fascist pseudo-scientific tendencies.

Mean reversion.

Used to be a bigger fan, but for the same reason I became more libertarian I'm not so sure it's a practical philosophy. The biggest issue is that as soon as someone decides what is or isn't good genetics you get a lot of bias. The majority of the human experience is social anyways.

Don't approve, because we can't study it without injecting adjectives or racism,

It's raising it's ugly head again because AI is finding new "correlations".

It’s “Lemmings”
