The only MBTI types I am not highly confident of are Roosevelt, Truman, Clinton (ENFP?), Nixon (INTJ?), and Bush II.
Roosevelt is often typed as ENTJ. But I think it's because he was a 8 that he looks like a Te-dom. Staline was a true ENTJ 8w7 So/Sp, and I think the difference is pretty clear. Staline was a "visionnary" in some sort, driven by a vision, by his own word, FDR was, above all, a pragmatist, and not dogmatic like Staline was.
Truman could have been STJ.
Clinton was an ESFP, I think. He was not an idealist, but a charming performer. He leaves me the same impression than the french president Jacques Chirac: an opportunist and an arrivist who is not driven by any specific abstract concept, but ultimately a -funny- president.
Nixon was STJ, I think. Not NTJ. Too much traditionalistic.
ESTP for Bush II seems right.
I can't vouch for their enneagram types, but you notice the extremely high prevalence of 3s, 6s, and 9s
Yes. That's in part because they are very current. 7 and 6w7 are very currents too, but there's not of them, except JFK. That's because they would be reluctant to such kind of responsability. By contrast with 3s who are very prone to take the role of social leaders.
Also, *chuckles* the very low prevalence of sx?
Yes, I noticed that.
Actually, there is no Sx-dom, and the only Sx-second are the So/Sx Reagan and Clinton, who clash by their unusual colorful attitude for a president.
You can also notice the absence of So-last. Which is quite natural after all. So, every of them are So-dom, plus the Sp/So. Not Sx/So because they are too much intense and extreme for that I think. The only example of Sx/So people who lead a state are Adolph Hitler, Leo Trotsky and the imam Khomeiny...
9w8 and 6w5 seem to be very prevalent.
Nine/Ten Ss vs four/three Ns...
Eight Es vs five Is...
Eight Ts vs five Fs...
Seven Js vs. six Ps...
Very interesting...
Yes. So ESTJ. Which is often considered to be the type of the cultural aura of the USA.
It's interesting to compare with the french presidents. If my guess is true, the typical french president is an ENTP. You can also notice the higher prevalence of Sx (but still no Sx-dom) and also the prevalence of 7w8 and 8w7.
