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."

What about killing off girl embryos...

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.
