First, there are many studies which are based on self-reports, which does not make them less valid. Do you know that The bell curve uses NLSY data which is entirely self-reported? Do you know that SMPY was entirely self-reported too? It does not make them not worth someone's attention.
Second, you experience serious troubles with reading comprehension. The high IQ group consisted of 350 people total at the time of survey, and the sample was a couple of dozens. You missed it. I doubt that you ever read the full report. You also said that I support outrageous things like slavery and human trafficking, while I just said that if the private sector behaves more effectively than public one, eliminate the analogues in public sector. I never said that slavery and child abuse must be encouraged, in fact, I meant quite the opposite: if they are nonexistent without a state, don't involve the state! If the state appears to be the only option to get rid of them, then use the state. That's why I'm a minarchist and not an anarcho-capitalist, besides the need for foreign policy.
Assuming that you cannot and unwilling to read I'm not going to argue with you. I suggest you to read this, this and this.
