well in this case, stating my source is crossing a line. i will refrain from posting statements and stick to questions on this forum.
dsadsa, the government has been working on genetic intelligence for years. they have to be 10 steps ahead of the public, so that a natural genius doesnt come up with something that they are unprepared to contain. this isn't speculation by the way. within the next 10 years all of this will be forced to surface otherwise chaos will ensue and the powers that be wont have their power anymore.
To what extent can something similar to this be done to humans so as to make our own species more intelligent, given today's technology?
It depends on what exactly you have in mind with the term "done". It is quite easy to change the genetics of a developing life form than one that has already developed. With our current level of technology we would well be able to change the genetics of a blastocyst and thus create a (likely) more intelligent human. The equivalent procedure for an adult would be much more difficult. Genetic therapy is a frontier science right now.
However, it is important to recognize that our technology isn't holding us back. Our knowledge is restraining such advances. We simply don't know enough about how genes affect intelligence, what genes are responsible and what those particular genes are doing. In fact, there is hardly a consensus about what exactly intelligence is, and how it can be defined. One of the reasons for this is that the brain is capable of feats of intuition and understanding in seemingly unrelated realms (i.e. naturalistic intelligence vs interpersonal intelligence). Cognition is a very complex operation; an integration of many different functions. Once neuroscience unveils the mechanisms that produce these functions, we can begin to look for the genes that produce those mechanisms.
For our purposes, lets define define intelligence to be proficiency in academic research or the ability to score high on an IQ test.
Government enforced sterilization of people with exceptionally low IQs or an exceptionally poor proficiency in academic research. Couple that policy with forcing people that have exceptionally high IQs or great proficiency in academic research to have high numbers of offspring. This method could be used to enhance/restrict any genetically influenced trait within a population, and probably within a relatively short amount of time. Basically treat people like cattle. Contemporary views on morality and ethics would prevent this from being a popular policy. This would not necessarily produce a better human. It would produce a human that is better at standardized tests or academic research. And that likes Star Trek - a lot.
For our purposes, lets define define intelligence to be proficiency in academic research or the ability to score high on an IQ test. I'm suggesting that we not concern ourselves with the function of genes that are correlated with high intelligence and simply produce a human possessing all of them. We already know everything required for this procedure and since you say we have technology, there's nothing 'holding us back'.
Can you please refer me to a reliable source as to how this works? (the technology used to change the genetics of a blastocyst, I'm not interested in this procedure for an adult given its difficulty)
