Arguably, some people don't use Candy Crush in moderation, and that also carries very unhealthy side-effects. Again, I would come back to this point that there are gradients between "never talk to people", and "become an extrovert". People understand that gradient when it comes to subjects like boredom and Candy Crush, many people don't understand that about what are essentially just social lubricants for introverts.

So yes, I can see a world where someone uses an app or system like this to avoid conflict to an unhealthy degree. And to be clear, a friend that refuses to meet your extroversion halfway or that demands that you jump through excessive hoops to interact with them is a bad friend, period. But I really disagree that the potential for that kind of abuse means that introversion is somehow a problem. I don't see a difference between boredom and small-scale social anxiety.

There is a well-meaning kind of person that I will occasionally run into that is very interested in getting rid of personality traits I have that they consider problematic. And often I find myself eventually tolerating more quirks in them than they will tolerate in me.

Friendship is, in part, about people accommodating for each other and helping each other -- that's the part that makes friendship special. So I provide affordances for people who get incredibly lonely if I haven't spoken to them in a week, because I recognize they can't just 'act like an adult' and take it at face value that I haven't abandoned them. I provide affordances for people by adjusting my body language, how I talk to them, and where I look while I'm talking to them, because I recognize that some extroverts have trouble emotionally connecting to other people without a lot of extra signals of affirmation. In the same way, I make affordances for people by calling them instead of texting them, because some people place more emotional importance than I do on hearing a voice.

All of this is, to be blunt, crazy. It's just that some people have a random chunk of their brain constantly making them feel anxiety over the fictional idea that "I love you" means more when it's heard in someone's voice then when it's written on a piece of paper.

But generally, we don't describe those people as having a problem. It's not a problem that they have a section of their brains that says, "if someone doesn't make small talk, then that means they're being confrontational or angry." But it is a problem for some reason that I have a section of my brain that says, "if you ask someone for a favor, maybe they didn't actually want to do it, and maybe they might lie about their preferences." And I do kind of regard that as a double standard, because when I accommodate extroverted behavior, I just feel happy to help my friends -- I'm not thinking in the back of my mind, "that person should see a specialist."

I dunno. Every day, everyone here tolerates tons of personality quirks that seem to me to be way, way more crazy, and way more debilitating, and way more problematic for society than something as trivial as being anxious about disappointing friends if a movie night gets canceled.

Any personality trait or quirk, if taken to the extreme, will become a disorder. What is different about introversion that means it's dangerous to accommodate it?
