Single Gene Can Boost IQ By Six Points

ananyo (2519492) writes "People are living longer, which is good. But old age often brings a decline in mental faculties and many researchers are looking for ways to slow or halt such decline. One group doing so is led by Dena Dubal of the University of California, San Francisco, and Lennart Mucke of the Gladstone Institutes, also in San Francisco. Dr Dubal and Dr Mucke have been studying the role in aging of klotho, a protein encoded by a gene called KL. A particular version of this gene, KL-VS, promotes longevity. One way it does so is by reducing age-related heart disease. Dr Dubal and Dr Mucke wondered if it might have similar powers over age-related cognitive decline. What they found was startling. KL-VS did not curb decline, but it did boost cognitive faculties regardless of a person's age by the equivalent of about six IQ points. If this result, just published in Cell Reports, is confirmed, KL-VS will be the most important genetic agent of non-pathological variation in intelligence yet discovered."

      Not really... that's just another verb that still suggests it somehow can change within a given individual.

      How about this then: People who lack this gene on average, for a given population, are measured to have an IQ that is 6 points less than those who do.

      I think that the reason why the word "boost" is used is because they are working on developing a gene therapy that would "boost" IQ in people who don't have the gene. In that context, it's perfectly acceptable.

      Personally, I wouldn't sign up for the first version of such a drug as most IQ tests only measure certain skills such as memory, logical,and spacial thinking and then combine them into a single score. Very little artistic or humanistic traits are tested. So, while this gene may have an influence in higher IQ, it may also decrease some other trait that they didn't measure for.

      Something about this strikes a chord.... Oh, right... Divergent....

      That is my intuition anyway: if the SD of a single IQ measurement is 15, then the SD of the measurement on the population that possess the gene is 15/sqrt(718*1/5)=1.25. The SD of the measurement on the population without the gene is 15/sqrt(718*4/5)=0.63. The SD of the difference should be 1.25+0.62=1.88. So yes, 6 points is over 3-sigma.

      According to various IQ tests, I'm smarter than Einstein.

      IQ tests are bullshit. Mostly because you can easily train them and gain 20-30 "points" fairly easily. Especially if you start out fairly "intelligent" already (read: share the way of thinking and the train of logic of those that design these tests) because once you play in the 150+ league, what matters is concentration and speed. Finding the logical pattern quickly and then being able to track various variables at the same time is usually the key.

If you look at the average height of, say, Japanese people over the 20th century, you'll find that their height increased (on average) by several inches. Was this due to genetics? Or was this due to better nutrition (more specifically, more protein in their diet)?
