My Multiple Personalities

A shoutout to Susie Lindau for her hot-off-the-press post on the Typealyzer. A Swedish gentleman named Mattias Ostmar “imagined” (as he put it) a site that tries to figure out your Myers-Briggs type, based on the writing style of your blog. The analysis is based on a corpus of writings collected by Mr. Ostmar, and a text classifier written by his colleagues at uClassify. It’s all for fun, of course, as the site creators would be the first to admit.

Every time I take the Myers-Briggs, I get a different result. I also suspect that the way the test is given will reflect back more who you want to be (or how you want to think of yourself) than who you really are. But my blog reflects who I really am, doesn’t it? What does my blog say about me?

Let’s find out.

When I typealyze this blog, Multo (Ghost), I get back the result ISFP — an Artist.

They are extremely gifted at creating and composing things that stimulates the senses, such as art, music or food. They often prefer working quietly, behind the scene as a part of a team. They have no desire to lead others and they don’t want to be led. ISFPs are sometimes not good at giving him/herself enough credit for things they did well.

Common satisfying careers: Fashion Designer, Artists, Interior Designer, Landscape Architect, Nurse, Massage Therapist, Botanist, Teacher, Geologist, Translator, Social Worker, Occupational Therapist, Cosmetologist and Translator.

Notable ISFPs: Ulysses S. Grant, Sofia Coppola, David Lynch, Brad Pitt, Michael Jackson, Beyonce, David Beckham, John Travolta, Liv Tylor, Jacqueline Kennedy Onassis, Nero and Wicket the Ewok.

I will plead guilty to the working quietly and not giving myself enough credit, but I have never had, or even thought about having, any of those listed careers. The company I keep isn’t too bad though (But Nero? Wicket the Ewok?).

I was tickled by my “brain activity” analysis. Apparently, I’m a perfect square.


I guess that means I’m well-rounded, at least in L-Infinity space (ask a mathematician friend to explain that joke to you). No wonder Myers-Briggs can’t figure me out.

Next, I typealyzed my professional blog, Not too surprisingly, I got a different result: INTJ — a Scientist.

They generally withhold strong emotion and do not like to waste time with what they consider irrational social rituals. This may cause non-INTJs to perceive them as distant and reserved; nevertheless, INTJs are usually very loyal partners who are prepared to commit substantial energy and time into a relationship to make it work.

Common satisfying careers: occupations within academia, research, computer programmers, system analysts, specialized consulting, engineering, management, science, and law.

Notable INTJs: Mark Zuckerberg, Jane Austen, Isaac Newton, Karl Marx, Friedrich Nietzsche, Bobby Fischer, Jodie Foster, Isaac Asimov, Martin Luther, Nikola Tesla, Elon Musk and Palpatine.

This is much closer to my own self-image, and to my career track. Interesting company, too. Brain activity: all thinking, no feeling.


That’s appropriate for the subject matter of the blog. It’s interesting that I score so much higher on intuition than on sensing. Incidentally, the Win-Vector Blog (our company blog), which is written mostly by my business partner, with occasional contributions from me, also typealyzes to Scientist, but with almost equal scores along the sensing-intuition axis (slightly biased toward intuition).

Finally, I typealyzed an old dead blog of mine, Ephemera. The writer of Ephemera is ESFP — A Performer.

They enjoy work that makes them able to help other people in a concrete and visible way. They tend to avoid conflicts and rarely initiate confrontation – qualities that can make it hard for them in management positions. ESFPs are excellent team players, focused on completing the task at hand with maximum fun and minimum discord.

Common satisfying careers: Artist, Performer, Actors, Teacher, Social Worker, Nurse, Event Coordinator, Chef, Fashion Designer, Jeweler, Retail Manager, Recreation Worker and Interior decorator.

Notable ESFJs: John. F. Kennedy, Richard Branson, Hugh Hefner, Deepak Chopra, Paulo Coelho, Quentin Tarantino, Mel Gibson, Justin Bieber, Miley Cyrus, Katy Perry, Lady Gaga, Megan Fox, Jamie Oliver, Robbie Williams, Dan Brown and Chewbacca.

Her brain is all feeling, little thinking.


All in all, it’s a cute demonstration of how our words shape the persona that we present to the world. Can I say that any of these blogs reflect the “real” me? I can say that Multo is the blog where I have the least to prove, in that it is purely for fun, and not to further my career or any artistic aspiration. I’m not consciously trying to be anyone in particular, so I become everyone — or perhaps, no one. How zen.

The Typealyzer is here. Try it for yourself.

One last thing, because I can’t resist. uClassify also created a blog gender analyzer. Multo and Ephemera come out female — but comes out male. And what does that say about words and cultural expectations?

  1. Fascinating. I have consistently been an INTJ for over 30 years since I was first tested. I just ran my blog and it immediately came up with INTJ. The blog gender analyzer said the blog was probably written by a male but was largely gender neutral. I’m happy with that. Your analysis with different blogs is more interesting and I think you are exactly right about our words shaping the persona we present to the world. However, if I remember correctly Myers-Briggs is testing for your core personality type and although you might change your personality for a while, say at a party, or while at work, you always return to your core personality type. So, is your Multo personality type (ISFP) the real Nina and everything else just a stretching of the elastic band for a period of time until you snap back to the core? Or are all the other personality types just as real for you which suggests that the idea of a core personality type may not be valid?

    1. ISFP is not my core personality type, or at least I don’t feel that the description fits me particularly well. And also, I just typealyzed Multo again just now (after this post was added) and I got a different personality type — ISTP, “the mechanic”, or engineer, which does feel like me. Although the careers they highlight — firefighter, race car driver — and the famous people they highlight — Rumsfeld, Jobs, Rommel — are hardly me (lord, I hope not…). My perfect brain square is now stretched a bit to the practical half of the plane (T and S).

      And that has generally been my experience with Myers-Briggs. I sit at some unstable equilibrium point, and how I score has as much to do with whether the sun is shining and what I last ate for dinner as it does with my so-called core personality.

      Whatever model Myers-Briggs has of personality, I don’t fit it well.
