I am a med student, former PhD student.  Understanding the world and people is my passion. I feel more in touch with emotions than most INTPs, I express and accept them well, but I only connect emotionally with a very select few people.  I do consider emotions to be purely physiological chain reactions resulting from experiences that cause potentiation of synapse networks in the brain. That doesn't make them any less real or valid. I enjoy understanding the bio-psycho-social roots of these neural networks and how to help people grasp and function in their own context, which is why I am pursing a medical specialty of psychiatry.
