I'd like to apologise for all of the garbage posting in this thread. You are addressing the topic. In emotional subjects like this people tend to resort to cheap diversion tactics to avoid the issue, compounded by what seems to be a sense of their moral superiority in their undemonstrated egalitarian beliefs. It's almost like a religion. Anyway, you bring up some anecdotes, and your main point seems to be that cognitive abilties are not correlated, which impugns a general factor. That is a valid argument, but it rests on data establishing that. Do you have some?
