I was recently pointed to the Youtube channel Psychology in Seattle. I think it's one of my favorites in a while.
I'm personally more interested in workspace psychology than relationship psychology, but my impression is that they share a lot of similarities.
Emotional intelligence gets a bit of a bad rap due to the fuzzy nature, but I'm convinced it's one of the top few things for most people to get better at. I know lots of great researchers and engineers who repeat a bunch of repeated failure modes, and this causes severe organizational and personal problems as a result.
Emotional intelligence books and training typically seem quite poor to me. The alternative format here of "let's just show you dozens of hours of people interacting with each other, and point out all the fixes they could make" seems much better than most books or lectures I've seen.
This Youtube series does an interesting job at that. There's a whole bunch of "let's watch this reality TV show, then give our take on it." I'd be pretty excited about there being more things like this posted online, especially in other contexts.
Related, I think the potential of reality TV is fairly underrated in intellectual circles, but that's a different story.https://www.youtube.com/user/PsychologyInSeattle?fbclid=IwAR3Ux63X0aBK0CEwc8yPyjsFJ2EKQ2aSMs1XOjUOgaFqlguwz6Fxul2ExJw
You might also enjoy the channel "charisma on command" which has a similar format of finding youtube videos of charismatic and non-charismatic people, and seeing what they do and don't do well.
