Introverted Intuitive Feeling Perceiving: The Dreamer
Sweet-natured, compassionate, and idealistic individuals who are quiet, but speak directly from the heart. Often have their head in the clouds, but this only serves to fuel their flourishing creativity. Seek peace for themselves and others. Often gullible and easily distracted.
Granted, there are a lot of shared traits between the different types, so he could easily fall into a number of categories.
I would put him as an INTJ. Quiet. Thoughtful. Analytical. Prefers to be alone. Usually attracted to those who stimulate them intellectually. Less comfortable with the unpredictable nature of emotions. When asked a question, they will often wish to take time to consider the issue before coming to a conclusion - and generally will feel that others are foolish for not agreeing with what they present. They enjoy the pursuit of knowledge and wisdom. Have absolutely no problems pointing out when someone is clearly wrong according to their opinion. They can come across as rather blunt. Not particularly warm, but self-assured. They enjoy engaging others in discussions of topics that they find mentally stimulating. Hobbies often include reading and artistic pursuits.
Out of curiosity I decided to fill out a Myers-Briggs test with the answers I thought he would give and got the same result. So, at least it’s consistent with my take on his character.
Traditional, loyal, kind, and observant of others. Value stability and cultural norms, and are often consistent with work. Known for their kindness and willingness to go to any length to help those in need. Often fear change and try to maintain peace.
