I am a Role Model who loves the learning laughing exploring thing.

I am somewhere near the personality "cluster" of Reserved. I hope I am more open than that though. I agree with the study in that I too believe people change their cluster over time. Interesting!

Personalities are phenomenal to say the least and undefinable under any scientific strata. Having to survive in a world of war, disease, famine and racial bias makes one something they do no want to be classified as. Emerging through this has produced some of the most prolific and unique people that I don't think would fit into your study.

I don't see a link to the paper outlining the research in the article. Certainly not an academic approach. Maybe there isn't one!

According to the vagrant in Team America World Police, there are only 3 types of people in the world. Fascinating.

I agree with youyr commenting critics. As a retired staff developer, I looked at a number of these "personality" scales and concluded that few of them are of real value.The only one I ever found that was useful was Anthony Gregorc's "Style Delineator." Gregorcs' solidly research=based model looks at the person's style(s) of information processing. Those info-processing styles determine behavior much more than any "personality" scale.

sorry, but there are so many of these, and they are popular because people like to BELONG to something... and the powers that be find it useful for people to feel as if they belong to something, too. if you know your demographics you can sell whatever you're selling more easily, be it a product or a policy (or even a religion). i don't buy it.

I'm sure that you know that the word ' personality ' comes from Latin, meaning persona, to wear a mask. Therefore, at best it only refers to four types of mask.

In the western world up until the Age of Enlightenment and the birth of modern science the Catholic Church was the arbiter in all matters relating to the individual. As science began to gradually make progress and treat common diseases faith in prayer and the Catholic Church began to wane in the light of results that prayer failed to achieve.

In the world in which we live science is the current arbiter, therefore, to promote any theory, even a theory that might fly in the face of reason the best way to go about it is to seek scientific endorsement and of course the creation of a pseudo-scientific vocabulary aids in the process.

I don't believe any of these things. I put no faith whatsoever into these "tests".
A Magic Eight Ball is every bit as reliable.

Take the test, put it aside.
Take it 2 weeks later.
You will Not get the same results, proving, as has been noted elsewhere, that it is a load of Crap!

I took the test once and it said I am ESTJ-T. Am I really a Sentinel and my role is social engagement? Maybe. I know that I am a voice of activism in a world that seems to be unraveling for many of us who live within it. Fairness does not exist but we have to approach everything with logic and use evidence and facts. Trump and many others want to use their own facts and this alone is worse than religious indoctrination. It doubles up on those who want Democracy when the GOP marries into the religious right. Be diligent and be on guard.

Interesting.
But "average" is not a personality type!

In my opinion, the traditional 4 types theory is better:

It would be fun to have a link to the questionnaire.

Into which cluster belong people who do not.like reading White on black?
