This may actually be a symptom of hating your co-workers.

There are people I like to pair with and people I am not as productive when paired with.

Try to pair with someone you like.

I prefer to discuss the design with co-workers and then work on my own. I'm more efficient that way.

Don't measure only your productivity - measure the team. When you pair with someone with a different skill-set, some learning also happens.

A good analogy is with sports. In a good team, every player knows what the other is doing, not because they can observe each other, but because they know each other so well they can predict what will happen in the field.
