I have seen people with that personality type be able to just basically tell people what they want and get it. It's really a sight to behold.
"I need 50 million." "Okay boss.
I think there's two mechanisms at work. One is what you might call the "reptile brain," which reads such signals and simply interprets them as "this is my pack leader." The other mechanism is I think a cargo cultish belief in the power of those personality types to just always succeed no matter what. "Man, he seems like a winner." (This personality type seems to almost always be male, at least in my experience. Definitely not trying to be sexist. Might be being a bit reverse sexist though, since I do not find this trait redeeming.)
You would think that VCs would be inoculated against this kind of thing. You would think. But I personally know of two examples of people with off the charts alpha personalities who were sort of serial killers of wealth. Raise, burn, raise again. Their alpha personality trumped any notion of merit or track record.
