"So, my question is, is there anything relating to the SD that you think affects the soundness of the underlying argument? " What underlying argument? You are presenting a political position unsubstantiated by any facts. Arguing about the distribution of standard deviations about two imaginary curves is like arguing about something in Alice in Wonderland. (Note that i didn't make an argument either way about the std dev in my comment). Speaking against political correctness will probably get me downvoted, but here goes anyway, From your blog post, I gather you think "diversity" of genders/races makes better dev teams. All I am saying is "prove it". With data, not hypotheses. I have yet to see any real evidence for this, whether in terms of sustained commercial success or even in a statistical sense. Show us these supposed benefits from race/gender diversity as applied to software development and startups. Is that too much to ask?
