I dont like working alone - so this is not me - but I know another RD is this type and many of my developers are
INTP types are quiet, thoughtful individuals who don't mind spending long periods of time on their own working through problems and forming solutions. They are very curious about systems and how things work, and are frequently found in careers such as science, architecture and law. INTPs tend to be less at ease in social situations and the caring professions, although they enjoy the company of those who share their interests. They also tend to have a strong dislike for the bureaucracy, rigid hierarchies and politics prevalent in many professions.
Myers-Briggs provides a snapshot at one point in time of how a person 'feels', humans are not that shallow. We do have tendencies but they can change, especially if our environment changes. I believe the reason many people 'prefer' working alone is because they have never experienced working in an awesome team. Prior experiences of poor team behavior leads to a belief that working alone is better, and they are proved correct when the team doesn’t function well.
I have seen people who would have been labeled INTP become amazing team players when placed in a functional, inspiring and motivated team. It is a shame that teams of this nature are still so few and far between, leaving the INTP labeled people in the dark as to the possibilities of team interaction and delivery.
All the best
