"Tended to manage larger companies. Made up to $187,000 a year more than higher-pitched peers. Lasted as many as five months longer as the head of a firm."

This is an interesting research. I have not read the research underpinning this article on WSJ, but somehow I cannot shake away the notion that this is more correlation than causation for determining the CEO's success. Btw, do some of the famous tech CEOs - Steve Jobs, Bill Gates and Mark Zuckerberg - have low pitch or high? I think theirs might lean to the higher pitch of the male voice spectrum.
