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."
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.
Gattaca was a cautionary tale, not a blueprint for future eugenics. What if someone like Newton or Einstein didn't have the perfect genetic signature for IQ (as we *think* we understand it), and instead the parents select for a more 'intelligent' specimen with a higher IQ, but one that lacks creativity and 'genius' or a million other factors that would be important for a child's success?
Example: Hawking: 150ish IQ, John Sununu 190. (Granted those are 'internet' numbers, so take with a grain of salt.) Point being, IQ is not everything.
