Scanning Embryos For Super-Intelligent Kids Is On the Horizon 366

An anonymous reader writes: Stephen Hsu, a professor in theoretical physics at Michigan State University, has an article discussing the genetic underpinnings of intelligence, and how our understanding of it will eventually lead to smarter children. Researchers have detected genes that influence cognitive ability, but the effect of any one gene is very small — less than 1 IQ point at best. Genetically modifying such genes is unlikely to happen any time soon, but our ability to analyze an embryo's genome is becoming quick and cheap. As we isolate more and more genes that affect intelligence, this means prospective parents will soon be able to analyze a batch of zygotes and figure out which ones are likely to be the smartest. Hsu says a batch of 10 zygotes will probably have an IQ range of 15 points or more. As our understanding of intelligence genetics grows, that range will only expand. He adds, "The corresponding ethical issues are complex and deserve serious attention in what may be a relatively short interval before these capabilities become a reality."

      We can already ID future republican babies at 1 year with like 80% accuracy. That's not a crazy leap to find a partial genetic basis.

      And this is true, not made up: it's the easily scared babies. Babies that show a faster, stronger fear response to scary images are more likely to be republicans as adults by a pretty substantial margin.

        That is misleading. What happens is the conservatives show a different response to scary images. Which is better depends on the environment. It may be that conservatives are more prone to over-reacting to threats while liberals are more likely to ignore or downplay real threats.

      Gene detection means squat when it comes to intelligence or the positive impact it can have. Intelligence, even in a given area, means nothing without the ability to make use of it in a meaningful way.

      My family would likely be ones that have the intelligence gene (there's no way to say that without it sounding like bragging/ego, it's really not meant that way). I believe that based on a number of factors, including the level of participation of extended family members in their respective fields, psycho-educational testing where scores are in the 90th+ percentiles, etc. What that intelligence gene wouldn't show is the impact it can have. Combined with the intelligence in my family comes issues with depression, ADHD, bipolar disorder, failure to recognize/interpret social indicators (partly related to ADHD), isolationist tendencies, etc. Those might be local to our genetics, however, the "absent minded professor", "genius idiot", "troubled genius", etc. stereotype exists for a reason.

      For every major success in my family there's a major failure to launch, meaning they have a really hard time getting careers/life going despite what testing suggests. In my family I am one of the latter group. My Wechsler Adult Intelligence Scale tests (professionally administered) showed exceptional PRI scores like 98th percentile matrix reasoning & 97th percentile visual working memory and some truly horrible WMI/PSI scores as low as the 9th percentile. For me this has resulted in problems in school, friction in social arenas, bankruptcy, and currently: driving a forklift for a living. I have diagnosed & fixed a code efficiency problem in code that had been under constant optimizations for over 3 years, in a language I've never used, without seeing more than an outline of the original code, in less than an hour. Unfortunately that ability means nothing when working memory doesn't allow me to keep method names/etc in my head. It's akin to having the latest greatest processor with a tiny amount of RAM - the OS takes up most of the RAM and everything that's left is dedicated to the problem at hand - every time something else needs that space something important gets pushed out. Sometimes that's remembering to sleep/eat, others it's any concept of time, and mostly it's the "unimportant" details like method names/attributes/outputs (information that I can look up any time and isn't essential to the abstract core of a thing).

      Point is, just because you can identify a gene and manipulate it to get better scores on testing doesn't mean it's going to result in something "better".

      You can already observe the effects of that one in India and China where female infanticide and selective abortion is practiced for all kinds of reasons such as the need to pay excessive dowries, inheritance traditions and religious beliefs. The problem of ending up with too many single men is usually solved by kidnapping women in other parts of the country or in neighboring countries where people are less obsessed with stupid traditions that lead them to have nothing but male offspring and force-marrying the unfortunate women to their precious sons. In some regions of India like Bengal and Assam, for example, where the gender imbalance is fairly small the kidnapping problem is so severe that girls and young women cannot go anywhere unescorted for fear of being kidnapped by bridal procurement possies from neighboring regions where they have a large surplus of sons.

    If I were to choose a child from a huge batch of zygotes, I'd want the one that's generally disposed to be happy - easy going, social, even tempered, and not too fussy growing up. But apparently, geneticists aren't working on identifying the genetic correlates of those traits, even though we know that they are just as heritable as intelligence.

    I don't think that I'll have kids, but if I did, the thing I'd want most is that they grow up happy. I would work hard to make sure they grow up in an environment that encourages it. But genetics contributes a lot to happiness outcomes, and if I were offered well-tested genetic help, I wouldn't refuse it. Maxing out their intelligence would not be at all high on my list of priorities. Is this a weird attitude? I thought it was a kind of typical parent attitude, but apparently, geneticists have different ideas.

        My son is classified as 'gifted', has a low 140's IQ; plenty of ambition, and an amazing inability to satiate his curiosity about pretty much everything. I love my son to bits, but there are more than just a few days where I would give anything for him to be a normal everyday shlub like the rest of the kids on the street... Having a high IQ child is not all upside.. There's a lot of downsides as well. At a young age you have someone who can read at an adult level, is bored by books for his age group, but is not emotionally mature enough to read books for his vocabulary and curiosity level. Sitting in a car with the kid is torture... He has an ability to generate interesting questions at a rate faster than he can verbalize them. After about 2 hours, you are mentally drained... On car trips, we limit his questions to one every 5 minutes and you can see him practically exploding, waiting for the clock to change... Even at 5 minute intervals, a 6 hour car trip is torture. In addition to his insatiable curiosity, and need to solve problems, he's also extremely sensitive, both physically and emotionally... A radio that I can hardly hear is too loud for him. He didn't like walking through tall grass due to the prickly feeling of it on his arms or legs... If he feels he has been dealt an injustice, he can jump right to violent anger instead of engaging in some self control.

        It sounds like i'm describing someone on the Aspergers scale but he's been tested for that and on the first test, was marginally at the very bottom of the range, and the second test was just outside the range. He's in a school that is tailored towards gifted kids and he's thriving there, both academically and emotionally... He has a ton of friends and is slowly learning how to operate his brain...

        Like I say, I love him to bits and so far the rewards probably outweigh the negatives, but if I knew then what I know now, I don't think I'd consciously elect to select for greater intelligence at the Zygot stage.

          I think you are conflating different things. Higher intelligence does not necessarily mean higher risk of Aspergers or other social disorders. Your son could easily have been of average intelligence and still had the other problems you've described. Do you think he would have had it easier by being less smart?

          While our society tends to mistreat the very smart, even more it mistreats those with social disorders.

          My daughter is also gifted and scored an IQ in the 140s. Also has insatiable curiosity. Certainly she could (and still can) ask far more questions than us and her teachers could ever answer. But, she never has had issues keeping her curiosity under her own control. She quickly learned how to do her own research. But not at the expensive of purely social activities. She certainly pushed our patience and made plenty of mistakes, but never did anything bad. She's a happy teen who is doing very, very well in university (studying electronics engineering and physics). She's been with her current boyfriend (who is equally gifted) for over 2 years. And she's truly beautiful (scouts from fashion agencies regularly try to recruit her for modeling; she politely declines).

          Yes, in some respects my daughter is lucky. I don't think that her intelligence was a risk factor in inheriting any social disorders. And she's certainly using it in good ways.

      It was a cautionary tale to not focus too deeply on the genes one has rather than the potential one has. An invalid can best those with superior genes if they've got no fire, and a perfectly peaceful man can commit a horrible murder if everyone believes him to be perfectly peaceful.

      Luckily, Einsteins brain has been sequenced. The results aren't publicly available, but that's not the sort of information that's going to disappear. If we can identify "creativity and genius", then all the better. Just like we can identify intelligence. And having the right set of genes isn't the end-all-be-all of who you are. Even if you were a clone of Einstein, or say, one of his kids, that doesn't guarantee you're going to go on to do great things.

      You're right that IQ isn't everything. But GATTACA was most certainly a blueprint for future eugenics, and once it's available I really don't see an alternative.

Choosing them for looks isn't very ethical, seeing as look are very much dependent on the current fashion, but physical fitness and intelligence aren't quite the same thing. Seeing as most 'potential' human beings never make it, I don't quite share the moral dilemma in choosing the best of the best.

    Raising not only humanities average intelligence but much more importantly the lower end seems a phenomenal gain to me.

    • The current method where the people at the bottom are reproducing faster than the people at the top and the

    • Looks are a lot less to do with fashion than some suspect. Even different races have a similar idea (generally) about what is good looks.

    Positive side: Heinlein's "Beyond this Horizon"
    Negative side: Kornbluth's "The Marching Morons"

    If we don't do the first, we get the second. There's a reasonable argument that natural selection isn't working anymore, and in fact may have been reversed. At one point, poor eyesight or ADD meant the sabre-tooth edited you out of the gene pool. So, we'll have to add the chlorine ourselves. I'm not sure we should be editing genes directly, but selecting the best gametes from the available pool (for a given set of parents) à la Heinlein almost HAS to be done at some point.

    • At one point, poor eyesight or ADD meant the sabre-tooth edited you out of the gene pool.

      You have that backwards. ADD mean you noticed the sabre-tooth tiger and lived longer than your geeky friend who managed to focus on trying to build a fire. ADD is a positive trait if you have to constantly watch your back.

      And mother nature just didn't give a shit what happened to your eyesight past 30, but point taken.

      There's a reasonable argument that natural selection isn't working anymore,

      There is always selection, some people have (more) kids than others. Some people don't have kids. The "natural" aspect is meaningless and doesn't matter worth a damn. The question is merely

      • The crocodile and nautilus haven't changed much for millions of years. They found a niche and didn't have reason to change. We could do the same.

        I actually had a debate with someone about that:

        Me: Because they didn't need to.

  • In all honesty, why aren't we already doing this? The problem with the world is dumb people. If we can selectively breed out dumb people, how would the world be worse?

      And who will pick up your trash ? Einstein 2.0 ?
    • It could be worse because we don't understand the relationship between these genes and other attributes like compassion and morality. For example, some scientist boffin might discover that Gene 769 gives 1 extra IQ point but doesn't realise that it makes you into an unfeeling psychopath. Then we end up with a planet of super intelligent nazis.

  • Genetically modifying such genes is unlikely to happen any time soon

    Alpha children wear grey. They work much harder than we do, because they're so frightfully clever. I'm really awfuly glad I'm a Beta, because I don't work so hard. And then we are much better than the Gammas and Deltas. Gammas are stupid. They all wear green, and Delta children wear khaki. Oh no, I don't want to play with Delta children. And Epsilons are still worse. They're too stupid to be able to read or write. Besides they wear black, which is such a beastly colour. I'm so glad I'm a Beta.

    Quantifying something as dubious as IQ ... and then linking to genes ... makes astrology look respectable.
  • I'm sure that Slashdot is full of munchkins who always try to max out the stats of their characters, but please, don't bring that attitude with you when you're designing a baby. If you want the best for your kids - and I hope you do - you should basically do the opposite of what you would do for D&D - prioritize charisma, wisdom and health (CON). Don't worry so much about STR, DEX and INT. All of these traits have genetic correlates.

    Wouldn't the embryos change by the simple action of observing it?
    • Wouldn't the embryos change by the simple action of observing it?

      For obvious reasons, you want to do your culling before fertilization occurs. In Heinlein's story, they examined the otherwise-wasted polar body thrown off during the development of the cell. The genetic content of the final cell can be inferred from that. Not sure how well that would work out, real-world; but the story was written in 1942, and the idea hasn't been discredited yet (that I could find).

    Stuff like this is a pretty stark reminder that we're just a bag of chemicals, even though we've evolved the capability to do things like...post on Slashdot.

    This kind of thing is done in a somewhat limited fashion with high-risk pregnancies/IVF to select for embryos that don't have Down syndrome or other profound mental handicaps. And if an ultrasound indicates something wrong further along, amniocentesis is performed. Those tests are easier because it's the absence or malformation of a chromosome, and they're less controversial because the difference between a kid with 10 fewer IQ points in the normal range and a Down syndrome or Fragile X kid is huge. Someone who is otherwise normal might not be as smart, but someone with a mental handicap is never going to have a full life and be a hardship on their family.

    Given what we know about genetics now, I actually don't think selecting out traits that are clearly undesirable is a bad thing as long as there's some randomization and some things left to chance. 100 years ago, we only understood that "something" was responsible for traits, not that a particular sequence of nucleotides in your DNA causes the cells they create to behave differently. The problem is that there are still lots of religious people who reject all of this and blame diseases and defects on God's will. Not that Gattaca's a good example, but the main character's defects were a direct result of his parents rejecting genetic engineering and having kids the "old fashioned way," similar to religious people having a huge family, getting a couple of kids with issues, and just shrugging it off as unavoidable because, well, you know, God.

    When the country is owned and operated by the stupid, does it really help to be smart? If you're full of a room of people where the "leader" says that 1+1 = 3, and everyone else says "yes sir, you are correct". If you're the smart one and say that 1+1 actually equals 2 - in some sense you're actually going to be wrong. We don't respect the thinkers. We elect the charismatic ones with the team mentality that don't have half a brain in their head. Those who get ahead are the ones who actually follow the rules the best - not the ones that buck the trend and show that things aren't necessarily as they seem. I have school aged children, and I can tell you that success in school has to do more with conformity than it does with intelligence. The teachers reward the kids that sit there and take notes (even if they're useless). You get rewarded for doing the problem on the test exactly as the teacher outlined. If you were to solve the problem with some brilliant and novel approach, you might be penalized. If Einstein were alive today, he wouldn't even be recognized. he'd be some bum working on a team just like the rest of us. We've modified the system so that "anyone can do it" - whatever "it" may be - and if you don't follow the procedure, then you're not doing your job well.
  • ...there won't be anyone to run supermarkets, farmers or truck drivers to deliver food to anyone. Thus, while the entire population is reading slashdot, they will starve, die and go extinct.

    Perhaps the diversity of the gene pool as it exists today is smarter than any algorithm we could come up with to serve all the changing needs of our population to have the best chance of survival. It's clear to me that creating an entire generation of "geniuses", super models and super athletes is not going to do that.

  • While reading the article, one thought kept coming back: what if (some of) those genes coding for intelligence have some other negative effect? When you select all those highly intelligent embryos, will they grow up to all have e.g. crooked teeth, tiny penises, or autism?
  • Is that the smarter babies will have higher incidences of schizophrenia, bi-polar disorder, depression, and drug addiction, things usually associated with genius. Even Einstein had his problems. Source: http://www.medicaldaily.com/wh... [medicaldaily.com]

    Selecting for kids with even higher intelligence might mean they have more severe mental problems.

  • Every parent will have a "Sheldon Cooper" as a child . . .

    Maybe the selection will go the other way . . . sometimes a smart child is more of a challenge than the parents are looking for.
