From that we can see the value of brains. We can reasonably assume that SAT results are much the same as the parental SAT results. So those in the bottom quarter, earned something like $10,000 while those in the top quarter earned something like $15,000. But, as I recall, one of the views of the authors who presented those statistics was that higher income families tended to provide a richer intellectual environment and a stronger base of SAT tested knowledge for their children. If that's true then how do you quantify whether some, or all, of the correlation is genetically based as opposed to environmentally influenced? As the entire series of articles seems to suggest; the conclusion you can draw from these studies is "not enough information." I do, as I've stated, agree with your basic premise that groups differ in terms of mental aptitudes. It makes no sense that nature would channel every group of people into being "just the same" in terms of intellectual aptitudes. After all, many of our ancestors developed in distinct locales facing distinctly different survival challenges that weeded out those lacking different skills. Regardless of whether that is true, however, current "IQ" tests aren't smart enough to filter out environmental effects and quantify any actual differences that might exist, including slight differences in the parts of the brain utilized by different groups to attempt to solve similar problems. When it comes to supporting your point with studies I think your smoking gun proof will have to wait a little longer. As far as the value of "brains," that's interesting when you consider the value of brains today as opposed to the value of brains 50 years ago. I am in my 50s but I can remember a time when a willing worker with a strong back could make a good living even if he wasn't too bright. Now we have machines doing the work of most of those men and a much higher percentage of decent paying working jobs require good social skills, good appearance, some technological savvy and above average mental acuity. The highest paying jobs require, as you suggest, a highly functioning brain. The willing workers with dull brains and strong backs are, therefor, left with the lowest paying jobs or no jobs and the trend is that it will get worse. Some day we will have to acknowledge that there are far more of such workers than the economy needs and that the commonly accepted truism that "any man that's willing to work can support a family" is no longer accurate. What do we do then; put those people on the public dole, create a government work program or just let them become an agitated, disenfranchised seething force in society? We'd better start thinking about that. And yes, the new wealth will continue to be intelligence. Truly intelligent people have hit the lottery, more so than at any time in history, because the world has gotten so complex that the relative need for people with a big grasp of ideas and solutions is greater than it has ever been and the percentage of such people hasn't grown. Now, if some of those intelligent people blow up civilization all that will change and a willing worker with a strong back will have an important role again. Ed
