>Your preference for working alone is because you avoid being in a team

That's quite an assumption to make. We could easily turn it on its head: My avoidance of being in a team is because of my preference for working alone.

I might indeed be terrible in a team, and sadly go off alone. I might be terrible in a team, and yet happily go off alone. I might be terrible in a team, because I enjoy being alone so much more, and so I rarely get any experience with being in a team. (And when I do, I might barely put in any effort because I find it so tedious and unpleasant compared to my preferred manner of working).

If I know I'm happy doing A, and there is a disjoint activity B, then naturally my tendency to A will reduce my time spent doing B. There may or may not be correlation.
