Well that applies to almost anyone...

I mean, usually most people can't do as much for extroverts because they don't have as many problems, or else, it is harder to reach those problems due to the facade of extroversion which masks subtle issues, whereas introverts don't worry as much about facades so it's probably less difficult to get to those issues.

If you mean in the contexts that it's easier to form bonds with someone of the same -vertedness then I agree.
