Indy is Harrison Ford and he is Indy. I cannot know Ford’s Enneagram number, but I will guess he shares a close connection with his character’s.
Indy is physical. Swinging on ropes, wielding the bull whip, running pell mell — he is a true action hero.
He’s also smart. Clues, puzzles, deciphering, are all part of his job. He’s a professor for a reason.
Feelings, although present, don’t drive him. I think we can safely say that Indy’s no Heart Type.
I want to say “Nine,” but is that true? He’s not meticulous enough to be a One and he’s not impulsive enough to be an Eight. He rolls in the moment without hesitation, but it doesn’t have that gut-punch command an Eight shows. He’s competent and confident. Very Nine-ish.
The brain stuff can also be Nine-based, if it’s secondary to the physical. Is he a Head Type?
He’s too brazen to be a Five or Six. Seven? No, because he takes no joy in the outlandish gymnastics, mental and physical, he performs. It’s business, not pleasure. Sometimes his outlook toward his vocation is quite grim.
Like most adventure characters, Indy is a Nine. Easy to love, comfortable to watch, and a bit cookie cutter in his personality.
