Historical Figure MBTIAfter 100 Figures
When I first started this project, the goal was simple: type a few historical figures and see what patterns emerged.
Now, one hundred figures later, the biggest lesson I’ve learned is that context is everything.
It’s surprisingly easy to mistake environment for personality. Someone born into an intensely intellectual family can appear highly intuitive simply because they grew up surrounded by ideas, debates, and education. Their accomplishments may look visionary, but sometimes they are simply continuing a tradition they were raised in.
Irene Curie is a good example of this. Aaron Burr might be another. Both were clearly intelligent and capable people, but their environments were already saturated with intellectual capital.
Conversely, when someone emerges from a background with little precedent for what they accomplish — when their thinking cuts sharply against the norms of their time and culture — that often signals something different entirely. A genuine trailblazer.
Leonardo da Vinci is an obvious case. Wu Zetian is another. Figures like these do not simply inherit intellectual momentum; they create it.
In many ways, this is where certain personality types become particularly visible. ENTJs, for instance, repeatedly show up as master empire builders — people who do not merely participate in systems, but construct them.
Looking Beyond the Famous Figure
Another discovery that changed how I approach typing is the importance of looking beyond the famous figure themselves.
Typing the central figure alone only tells part of the story. What has been far more illuminating is typing the people around them: lovers, siblings, rivals, pupils, political allies, and enemies.
Personality does not exist in isolation. It forms inside ecosystems.
When I typed Leonardo, for example, it became much easier to understand him after examining Salai and Francesco Melzi. The dynamic between them revealed a cognitive balance that Leonardo alone did not fully explain.
The same pattern appears repeatedly throughout history. Once you begin typing surrounding figures, you start to see how certain personalities gravitate toward each other — and how those relationships shape the course of events.
There is also a statistical illusion that happens when we only examine famous individuals. Historical fame tends to select for particular traits — often visionary or unconventional ones — which means intuitive types appear disproportionately represented.
But once I began typing the surrounding people — the administrators, spouses, aides, and caretakers — the picture changed. Suddenly, sensing types appeared far more often than expected. And that makes sense. History is rarely built by visionaries alone. It is sustained by people who maintain continuity, stability, and structure.
The Bias of the Observer
Of course, personal bias is unavoidable in a project like this. As an INFJ, I naturally gravitate toward Ni-driven interpretations of personality. My understanding of cognitive functions is still evolving, and I’m certain many of my early typings will change over time.
In fact, some already have.
Not long ago, I revised my typing of Mozart from ENFP to ESFP after looking more closely at his temperament and creative process. Beethoven, whom I once saw as an INTJ, now reads much more convincingly to me as an ISFP.
That process of correction is part of the project itself. Typing historical figures is not a finished science — it is an ongoing exercise in pattern recognition, historical empathy, and intellectual humility.
AI as a Research Companion
AI has also become part of that process. It is a powerful tool for organizing research, summarizing sources, and helping structure essays like the ones on this site. I know some people have a strong bias against AI-generated writing — sometimes dismissing it outright as “AI slop.”
But for me, the tool itself isn’t the point. What matters is the curiosity behind the work.
