Dominant Introverted Thinking (Ti): Han readily points out flaws in other people’s plans. He likes to build things and make “modifications” to the Millennium Falcon. Han always needs to know why before he’ll join a cause, and is good at understanding technicalities. He doesn’t feel the need to rationalise his decisions to others and doesn’t particularly communicate his thoughts and motives very well.
Auxiliary Extroverted Sensing (Se): Han is a natural improvisor who is pro at using his environment to his advantage. He’s not afraid to through himself into dangerous situations and really has no boundaries to stop him doing crazy, wild and hazardous things. He tends to be a bit too impulsive when it comes to money, which puts him in a serious fix with Jabba the Hut. He doesn’t believe in anything that can’t be proved with physical evidence (such as the force).
Tertiary Introverted Intuition (Ni): Han is good at anticipating his enemies actions, allowing him to deftly manoeuvre around death at only a seconds notice. Though he’s an improvisor, he does plan ahead for unexpected dangers. For instance, he installs hiding places in his ship. He often doesn’t need people to explain themselves for him to figure out what their plans/motives are.
Inferior Extroverted Feeling (Fe): Though he’s fairly rational, he often reacts emotionally to other people, particularly other rational people (aka Leia). Han is one of the few Humans around who’s friends with a Wookie. Han claims to care more about himself than anyone else, but he does have a strong need to help other people out.
