    Um. Not sure what to say here.

    Finding a genetic marker for mental illness is one aspect of our attempt to understand the biology of mental illness, in the pursuit of more effective and targeted treatments for the millions of people suffering through anxiety, depression, schizophrenia, etc.

    If it becomes possible to safely genetically increase babies’ IQ, it will become inevitable
    Eugene Volokh
    Washington Post
    July 14, 2015
    Quote:
    Intelligence is, generally speaking, good, and more is, generally speaking, better. It’s better for the person in question. It’s better for society to have more intelligent people. It’s not the most important thing. But ask yourself: All else being equal, would you rather have your child have an IQ (for all the limitations of that measure) of 85, 100, 115 or 130?

    So here’s how it will happen. Say the 83 percent poll results hold, even once safe genetic modification is available (it’s not clear they will, given that at this point they reflect a purely hypothetical question, but say they do), and Congress bans such modification. Or say there is worry — understandable when it comes to a new technology — that the modification won’t be safe and will cause the birth of children with various birth defects or other problems, so Congress bans it because of that.

    Now it’s gone! No more of this awful technology. Except, wait: Say the Chinese don’t see things the way we do. Out come some number of babies with horrible birth defects (truly a tragedy, and as a purely ethical matter, possibly a reason against such experimentation; I’m just saying the ethics won’t matter much). And then things get worked out, and now the new generation of Chinese, or Japanese, or Russians becomes on average much smarter than the new generation of Americans. How long will American public opinion remain opposed to a technology that seems vital to national success, and perhaps even national independence?

    I agree with the author.

    Forecasts of genetic fate just got a lot more accurate

    A DNA IQ test
    In addition to predicting disease, geneticists can build models to predict any human trait that can be measured, including behaviors. Is this person destined for a life of crime and recidivism? Will that one be neurotic, depressed, or smarter than average?

    The scoring technology, scientists say, will soon shed uncomfortable light on such questions. In January, two leading psychologists argued that direct-to-consumer DNA IQ tests will soon become “routinely available” and will predict children’s ability “to learn, reason, and solve problems.” They believe parents will test toddlers and use the results to make school plans.

    To some, using foggy genetic horoscopes to decide who goes to college and who ends up in trade school sounds like an extraordinarily bad idea. On his blog Gloomy Prospect, Eric Turkheimer, a prominent psychologist at the University of Virginia, says the danger is that the scores will be overinterpreted to “recommend some truly dreadful social policies.” That, he thinks, would be “the worst possible kind of biologically determinist discrimination.” To Turkheimer, polygenic scores are “less than meets the eye” and about as fair as “predicting your IQ from a cousin you haven’t met.”

    Such views aren’t stopping the rapid pace of genetic exploration. Until last year, no gene variant had ever been tied directly to IQ test results. Since then, studies involving more than 300,000 people’s DNA have linked 206 variants to intelligence. It means genetic scores can now account for 10 percent of a person’s performance on an IQ test. That could reach 25 percent within a few years, as more data accumulates. One US company, Genomic Prediction, even says it wants to test IVF embryos for intelligence, so parents can discard those expected to be mentally unfit.

    Dystopia, dubious medicine, or a breakthrough in prevention? Genomic prediction may well be all three. What is clear is that, with the data needed to create predictors becoming freely available online, 2018 will be a breakout year for DNA fortune-telling.

    The quoted blog post of Turkheimer is here.
