What made history's minds tick?

Historical Figure MBTI

Hundreds of historical figures read through MBTI and cognitive functions — long-form essays, free to wander.

MBTI gets treated as either gospel or garbage, and neither is interesting.

What's interesting is that cognitive functions give you a vocabulary for how a particular mind moves — what it reaches for first, what it avoids when it's tired.

Leonardo da Vinci. INTJ, iconic, 1452–1519, and a nine-minute read.

So I wrote up hundreds of historical figures through that lens. Long essays, no quiz, no signup, free to wander.

Six hundred and thirty-five figures across seventeen eras. One essay each, and no test to take first.

The thing I keep running into is how often the era says more than the type. Two people with the same functions, four hundred years apart, are barely comparable.

That's less a flaw in the framework than a reminder that a person is mostly their circumstances wearing a temperament.
