Scanning Embryos For Super-Intelligent Kids Is On the Horizon

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.

  2. I hate to say it... by Kokuyo · · Score: 4, Interesting

    Sure, the first thought most people have, consciously or subconsciously, is "Would my parents have kept me if they'd had this option?" and the whole concept thus makes us very uncomfortable...

    However, looking at humanity as a whole and taking into account that we pretty much switched natural selection off... can we actually afford not to do this?

    I mean, billions of sperm and thousands of eggs never get to be a fertilized anything. Of the fertilized eggs, about a third or so actually manage to become a clump of cells trying to become an embryo and of the actual embryos, quite a few never make it any further. 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.

    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.
