Who's Who in the TARDIS: MBTI Profiles for Each Doctor Regeneration

In the realm of surprising scientific discoveries, where curious minds are diligently exploring black holes or seeking the truth behind the origin of the universe, a sect of dedicated fans and researchers have had their telescopes firmly pointed at the universe of Doctor Who. All 12+ regenerations of the Doctor, the immortal, eccentric Time Lord from the planet Gallifrey, possess unique characters and quirks. Our dedicated team of researchers hypothesized that these individual characteristics were not mere chance, but a predictable pattern and thus, they carried out a scientific survey using the Myers-Briggs Type Indicator (MBTI) on all the renditions of the good Doctor.

Ironically, the linguistics specialist analyzing the alien language of Skaro was the first to notice. "We thought we were studying alien psychology," Dr. Amelia TARDISian (not her real name, but wouldn't it be cool if it was) said. "We never expected the truth to be weirder."

The First Doctor: INTJ (The Grandad Architect)

Classic, grumpy, and somewhat reminiscent of the neighbor who scolds you for stepping on their pristine lawn, the first regeneration personifies the INTJ perfectly. Highly logical, strategic and valuing personal freedom, the First Doctor may appear outwardly unfriendly like all INTJs, but harbors deep wisdom and caring under those layers of severity.

The Space Hippie Ninth Doctor: INFJ

Enter the Ninth Doctor, the one that made us brood beyond our carnival of angst. With a vision for universal peace and a penchant for poetic goodbyes, he embodied the traits of an INFJ. Their defining characteristics – highly protective and empathetic but averse to conflict, make us wonder if we'd ever see the Ninth wield that deadly banana gun.

The Tenth Doctor: ENFP (The Charismatic Dreamer)

An ENFP personifies enthusiasm. And who else in the universe screams enthusiasm more than the Tenth Doctor? He embodied the charisma and curiosity of an ENFP, bouncing after mysteries with an energy that turned harmful radiation into harmless vitamin D.

The Eleventh Doctor: ENTP (The Quizzical Inventor)

An innovator at heart with a minuscule attention span, the Eleventh Doctor’s larger-than-life, eccentric ENTP characteristic fits him like his fez hat. Ever the devil's advocate, the Eleventh Doctor explores every angle of an argument, just for the sake of it.

The Bowtie Man Twelfth Doctor: INTJ (The Intellectual)

Maintaining the tradition of INTJ, the Twelfth Doctor was the same charismatic, sarcastic eccentric with a touch of added iciness. As analytical and strategic as an INTJ can get, the Twelfth Doctor certainly outwitted his adversaries with brilliance.

It's fascinating, isn't it, how scientists manage to find patterns even in sci-fi? Following this cutting-edge revelation, there are rumors circulating that aliens are planning an inner-age regression to analyze clairvoyant capabilities in Thundercats. The Doctor may state, "I'm the Doctor. I've lived for over a thousand years. No one's going to outsmart me," but clearly, our wonderful team of scientists has taken a step closer.

And for those of us anxiously awaiting the next Doctor's regeneration, we have a template for the MBTI traits they would possess: a love for fast-paced, erratic decision making with a dash of calculated quirks and odd banter. Just remember, the next time you change your appearance, personality and habits mysteriously overnight, rest assured, you've just experienced a Time Lord regeneration.
