"The problem, I think, is that extroverts collaborate more easily and this makes particular problems easier and/or faster to solve."
In my company there are a lot of extroverts that only do work in group meetings. They are insecure working alone. So six people have to go over a document for two hours which the person that has called the meeting could have written alone and sent to others by email for review. There is no real collaboration going on in those meetings.
It's about being extrovert. I would never voluntarily go into a meeting with tons of people where it's all talk and nothing gets decided. I find it exhausting but other people find those meetings invigorating.
