This seems completely wrong to me. If you look at who is the top 0.1% it's either inherited wealth, a few professionals (lawyers, certain medical specialties, etc.) who own their own practices, or people who've managed large groups of people (i.e. business executives). The third group is overwhelmingly full of people with good social skills, and skilled professionals are almost always personable too.
Politics, law, finance, the arts, advertising, religion, and the media all rely on persuasion. And because narcissists and sociopaths are so much more credible and charming than introverts and tech nerds, these professions are full of people who make a living selling stories - about themselves, others, and related brands and products.
This is why we have such problems with the constraints of physical or social reality. These people believe their stories. They experience any suggestion they're objectively wrong as an unreasonable threat to their status and self-image.
They feel the same way about any suggestion that other people's stories matter. To them, they don't. If they did matter they'd show some hesitation and nuance, and the persuasion magic would evaporate.
