I really like your idea because I have a very similar idea (though the focus isn't just rationality). I've been planning to make youtube videos for a while, but have had difficulty getting myself to implement. I have outlines on topics I want to talk about already like you have here! The difference would be that I'm doing it more for myself than for those out there, because I don't expect my youtube video to get out much. My biggest hurdle currently is video editing.
When I read your content, it felt like I was reading a news article. The only thing that might be an issue with that, is that you may want to have a bigger impact on your video. I felt like if you talked about something that made me critically think more, then it would be more engaging (and hence more appealing). Like, maybe explain Bayesian thinking and how it works since your target audience probably doesn't know anything about Bayesian?
I like this particular subject because I've been thinking about this topic as well. I do believe that the typical definitions of extrovert/introvert are a bit misleading. Dissecting what it means may be of help. For instance, when we mean energy I would translate that to mental resources. My capacity to handle stressful tasks can deplete my mental resources more. So if I were to define introvert, it would be more along the lines of being with people depletes my mental resources, and visa versa.
I don't think people are necessarily an introvert or an extrovert. It's probably easy to identify as one and feel the effects because you expect them. However, everybody is very complex and different, so categorizing people into introvert and extrovert seems to be an oversimplification. I can be outgoing or not depending on my current emotional state, the circumstances, or how mentally taxed I am. Not necessarily because I have a tendency towards introvert or extrovert. For example, when it comes to hosting a board game day, I feel lot's of "energy" because I get excited and I enjoy the activity. I'm going to want to be more social so I can increase my chances of winning. If I'm at a party, I immediately feel bored and because of my experience in parties, typically don't even want to engage with people. I also can feel mentally depleted just for being at a party. Likely, because of the stress of having to look good and having to feel like I need to make a good impression. I can guess why people would feel a burst of "energy" at parties though. I'd say it's mainly the different expectations in the setting that would drain the energy. In either setting I've both experienced a lot of mental resources and sometimes not much. That's where I think I agree with the original poster. Certain people are going to deplete your mental resources more than others, but whether you trust them or doesn't seem to make difference. I trust my sister to a large degree, but that doesn't mean she doesn't stress me out given the right situation.
That was one of the reasons I wanted to make the youtube videos as well, to leave a legacy. Hopefully I can motivate myself to keep working on it. Let me know if you're interested in sharing ideas or something. I don't think we will conflict too much since my channel will idealy be all over the place with talk about relationships and whatever other random things that interest me.
