Babble Hypothesis

A piece of research published in The Leadership Quarterly back in 2020 suggests that there's a "large, positive correlation between speaking time and leader emergence” found in existing research.

This correlation—being a correlation—does not authoritatively say that if you speak more, you'll automatically be perceived as, and perhaps even promoted as, leadership material.

But it does say there's reason to believe this might be the case, though there's also plenty of reason to be skeptical of what's become known as the Babble Hypothesis, because of how earlier studies were conducted (not terribly well).
