Functional Order: Ti-Ne-Si-Fe
The Doctor has a detached, analytical method of studying the world and views most encounters as potential data to expand his knowledge base; if he encounters something that does not mesh with the internal system of logic he has built, he flat out denies its existence and refuses to even consider that it may be true, even when it’s right in front of him. The best example of this is when he encounters Robin Hood; he has decided that Robin Hood is a myth, and cannot possibly exist in the real world, so he denies it right up until the end as he seeks ways to prove him a fraud. His inferior Fe appears for the first time when he asks Clara whether she considers him “a good man.” Throughout his seasons, Twelve works hard to develop his Fe, using flash cards with stock “I’m sorry” messages on them (“I’m sorry, but you’re about to die,” “Sorry for your loss,” etc), until he begins to connect to and care about people. Under intense stress, he becomes highly emotional and wrathful, to the point where his companions must force him to promise he will not “exact terrible revenge” for the wrongs done to them. He has a petty, insecure tendency to object to people calling him old and try to convince them he isn’t (“Grandfather? Oh, come on, Father please, at least! I mean, we look the same age!”). On occasion, he hauls out some moralizing, to shame people into better behaviors and rail against the human tendency for war. The Doctor lives in a world of potentials, and is not afraid to shift tactics, positions, and beliefs (provided they are rational) when confronted with ever-changing situations; his insatiable need for newness leads him to find companions and embark on new adventures, to encounter the unknown, and even to go to the ends of the universe to explore his own abstract theories (why do we fear the silence? Because we are not alone!). The Doctor’s big picture thinking comes in handy, because he often manages to stay a few steps ahead of his adversaries, but he’s also prone to subjective memories and impressions. He’s not remotely realistic when judging his appearance or that of anyone else (his insistence that he looks much younger than he is, his inability to tell if Clara is even wearing makeup, etc) and his former interactions with the Master, though irrational (he/she is dangerous, and he should rid the universe of him/her) drive him to give Missy multiple chances to find redemption. His Ne idealism and ability to see what she COULD become override his past.
Enneagram: 5w4 sp/so
Twelve is a more withdrawn, analytical, and detached Doctor than the previous incarnations – so much so that the sudden shift to knowledge and lack of concern for humanity troubles Clara when first they meet. He thinks in precise logical sequences, is intellectual and somewhat removed from his feelings for the first season. The Doctor focuses on developing relationships with a few select people – he does not allow just anyone to come along on adventures in his TARDIS, but instead chooses others who are smart, and inquisitive. He uses his 7 (disintegration) and 8 (integration) points well – reacting with excitement to new experiences and with aggression whenever anyone threatens himself or his friends. His 4 wing has an ego the size of a small planet and needs no one to like him to feel self-assured. He can be arrogant and emotional, concerned with figuring out his new self, and somewhat dismissive of people at first. As the series progresses, the Doctor starts leaning more into his 6 wing as when he wants support and friendship from Clara and Bill, but his 4ish melancholy over the past, tendency to avoid fear through throwing himself into new and stimulating situations, and overall sense of superiority rule.
