Updated Links I've updated the links to be more accurate, with more links to actual researchers in genetics and intelligence. These sites aren't overly technical - they're meant to be accessible to the mainstream, and I strongly suggest you check them out. < self referential bit > Long time readers will note that the links title has changed from "Human Biodiversity" to "Human Biodiversity and Genetic Engineering". This may seem like a minor shift, but it's more reflective of my predilections as a researcher and as a writer: I've always been more interested in engineering than pure science, and I've grown more and more convinced that exposition alone will not be sufficient to hammer home the importance of human genetics. It is in this respect that I differ most from esteemed peers like Steve Sailer and La Griffe Du Lion. They are well aware of the importance of genetics, but their emphasis is more descriptive than remedial. My inclinations run the other way, though these are tendencies rather than hard and fast rules. Now, I say "my" predilections, but I think that Joel and Razib concur. The three of us believe that human genetic differences are useful as explanatory tools rather than simply truths to be acknowledged. If I'm permitted a degree of self-reference, I think that this focus on genetics as part of the answer is one of the strengths of our site. Now, we are not doctrinaire "genetic determinists", as we pay constant attention to the interplay of genetic and social factors. Razib focuses on the interplay of population genetics and cultural differences. Joel concerns himself with the question of how evolutionary psychology impacts economics. And I concentrate on the societal implications of the genetic engineering of behavior. That doesn't mean that we don't have other interests, as there are plenty of posts on unrelated topics like Iraq, intellectual property, atheism, and hot policy wonks. But it does mean that this is a great site to read if you want to hear rational coverage of controversial topics - race, crime, IQ, genetics - that other bloggers are afraid to touch. < /self referential bit >
