Nice strawman, averages and distribution matters, not the exceptions.  No one ever said there wasn't a range, the entire idea of bell curves is built on that idea.

This is just anti logic at this point.  Like pointing at a gay person and then claiming that no one can claim that the majority of people are straight.

That a % guess works at all simply supports the point, even with todays crude instrumentation in measuring brain activity, and oh god is it crude, measuring little more than blood flow in the case of fMRI, we can already detect enough differences in distribution that "guesses" can be right most of the time.

Again, you are playing a losing game of "god of the gaps", every new discovery will only reduce your wiggle room until you have none left at all.
