I'd have to say when you have little to no life experience and you're isolated 24/7, it can be harder to come up with interesting/exciting conversations to talk about with others. Yes, we can talk about our favorite bands, we can talk about a new tv show we watched on Netflix, we can talk about the news, hell, we can even talk about the weather... and I'm not saying those aren't good topics to have as discussions, but because we're isolated so much from the world, it pretty much limits our ability to hold on a conversation.
I've thought more and more about this now that my job requires me to socialize with people more regularly and I've sort of noticed things.
I agree with FriendlyShadow in that I think the social cues that are a part of everyday life are lost on those of us that are or have been "
shut-ins" (myself included). I'd like to expand on it a little bit with my own thoughts.
The reason I say this is because normalized people are out socializing all day, almost every day, because they have obligations like work or school that requires them to be out and about; the daily social cues that they experience become a part of them. In other words, they learn the social "system."
It's almost like second nature or muscle memory; imagine a well-adjusted person--their subconscious thought might go something like this: "This person said this to me or acted this way, and because I've been in this situation every day of my life and am familiar with it, I will respond to them in this appropriately specific way." The response has been bred into them by the mere exposure to their vast number of social interactions and maybe... even Pavlovian. Instead of bells causing an automatic salivating response in dogs--a conditioned response--social cues cause automatic, conditioned responses in return by the participating speakers.
The person that has not been exposed to these social cues enough to learn them and absorb them into their personality will naturally not do well when it comes to social situations. Not to mention, the myriad
types of social situations. Someone that has been exposed to social cues growing up in Beverly Hills, CA (rich people) might not understand the social cues inherent in Detroit, MI (the hood).
So again, it follows that the person that has not been exposed to any social situation for any proper length of time to absorb social cues, will have a very hard time understanding those cues until they put the time in to understand them, probably through exposure.
My biggest problem(personally) I've come to find out is I think the reason I've been quiet all my life is because I had nothing intelligent to say and I'm ashamed to admit that. So, I guess I could kinda understand why people would choose someone less boring than me.
I seriously doubt that. Based on the level of introspection in your posts, I really do doubt it. If you can philosophize at length regarding your problems in an intelligent way, which I think you do, you can probably do so on other topics as well.
You're just socially fucked up like the rest of us due to many unclear and poorly understood reasons, which causes you to freeze up during social situations, but that doesn't make you unintelligent.
