> Absolutely no one I have met believes 1 and 2 Admittedly I am a little confused by your comment. You made the above statement, and then follow up with this statement: > As for 3, "average observable differences" in mental ability can largely be explained by socio economic factors If we are to assume you are being earnest here in your first statement in that you believe there ARE innate ability differences between humans and social factors don’t explain everything, can you explain how much innate ability differences are a factor in intelligence differences (using it since you brought it up)? And how do you determine it? What methodology are you using for that, and if you aren’t basing it on anything, what methodology should we use? If you are going to dodge the question and suggest you were talking about averages between groups (for which the question does still apply) and that between groups are a special case, then please share how much of a factor innate ability differences are in intelligence within groups? And how you determined that?

Before I start, you really need to watch your tone and not pretend that you are a hunter on a hunt about to kill a nasty prey. My responses are clear, comprehensible and from your reply it is clear that you understood all of my points perfectly well, yet chose to use phrases like 1. If we are to assume you are being earnest 2. If you are going to dodge the question etc. I am a statistician and all of your questions have banal answers. For individual differences you can plot the bell curve and the standard deviation gives you the individual variances. I was clearly talking about population averages in 3. > can you explain how much innate ability differences are a factor in intelligence differences (using it since you brought it up)? And how do you determine it? AFAIK remember, heritable IQ/ height is estimated to be a bigger factor at an individual level. However, there is no existing causal methodology to determine it. Instead we have correlational regression models that make a lot of strong assumptions that are practical. There are various papers but it is clear that IQ is highly heritable like human height. Also, I am going to replace "innate" ability with "inherited" ability because there is no methodology that can tell you how much of Roger Federer's tennis ability is "innate" and how much is "coached". > talking about averages between groups Your wording is ambiguous. But assuming you are talking about intergroup differences. When you sum up IQ or height within a group, the observation from regression models is that individual hereditary differences cancel out, and intergroup height and iq differences are easily explained by socio economic factors in a correlational regression model and heritable height/iq is an insignificant factor. Once again- this is not a causal model. Only correlational. And this is just common sense. We know from life experiences that different people have differing IQs and heights from an early age. We are also aware of how important it is to have a school system - instead of just letting the kids figure things out on their own. The environment matters because we do have to work to nurture the inherent talents of a kid, otherwise that potential will be lost. > please share how much of a factor innate ability differences are in intelligence within groups? I expect the per sample standard deviation to be the same across different ethnic groups. For inherited "ability" i expect the total variance explained by "inheritance" factor to be the same across ethnic groups. I doubt if such an analysis has been conducted, because I don't see the value in this kind of subgroup analysis. Do you have any references to such studies? Have you seen data that contradicts this?
