I think what is meant is that many extroverts don't fully understand what they're talking about. Their communication often consists of catchphrases which sound good and clever, superficially. But by prioritizing form over substance, they don't allow themselves to develop a nuanced, in-depth understanding of anything. They tend to fall back on socially accepted axioms as opposed to thinking from first principles. Catchphrases and first-principles thinking don't mix. Catchphrases are more geared for triggering emotional responses. I find that, on average, extroverts don't have the same level of rational, critical thinking as introverts do because everything they say and hear passes through some kind of emotional layer. For example, with many extroverts, what I've found is that if they tend to get defensive when you're trying to share ideas and they often don't seem to understand nuanced arguments. I believe this is because, to the extrovert, the primary purpose of communication is to exchange emotions, not information. Also, when an introvert debates an extrovert, they're not playing the same game. The introvert tends to be laser-focused on crafting the most logical arguments possible. On the other hand, the extrovert is laser-focused on crafting the most palatable argument which they believe most people will agree with. The extrovert is laser-focused on triggering desired emotional responses. Introverts tend to craft arguments as if trying to convince god himself. Extroverts know that this isn't how you win debates; they know who their audience is and what their emotional trigger points are. They know what narratives they need to invoke to activate blind-spots and neutralize opposing arguments. IMO, the reason people are extroverted is mostly because they enjoy the emotional validation which social interactions provide (both inbound and outbound). Unfortunately, this tends to cloud their judgment. That said, the zero percent interest rate economy has given extroverts a massive advantage since it has made it possible to profit from emotional thinking... People made a lot of money from companies like Facebook, Twitter, Bitcoin, Dogecoin, Bored Apes NFTs, real estate in trendy inner-city suburbs... Most people got into these assets with an investment thesis of "My friends agree this is cool!" In a proper, functioning economy that kind of investment thesis typically wouldn't pan out... Certainly not to such extent as we have witnessed.
