Blog’s Myers-Briggs Type INTJ, says Typealyzer

by, from the folks at, determines the “personality type” of a blog. Specifically they’re using the ubiquitous Myers-Briggs Type Indicator, of a so-called “Jungian personality type”.

Typealyzer’s web-based system is backed by‘s classifier-as-a-service implementation. I don’t know what they used for training data, but given that, it’d be easy to use LingPipe to do this kind of thing (see any one of our classifier tutorials).

According to Typealyzer, the LingPipe blog has personality type INTJ, which they’ve dubbed “The Scientists”. Fair enough, but if you look at the “Analysis”, a star plot centered on a brain for left/right-brain graphical impact, you’ll see that we’re off the charts (well, off the brain anyway) on the Thinking (T) scale, pretty high on the Intuition (N) scale, and a bit over the edge on the Sensing (S) dimension.

My (Bob’s) Myers-Briggs type is ENTP (E:21, N:45, T:39, P:39) as of last testing. My type hasn’t changed at all since high school. My mom tested me in high school because she was practicing giving the test for her doctoral dissertation on approaches to writing and personality type. If you read the descriptions, an ENTP sounds like a fickle INTJ.

I’m thinking most blogs are going to be type E (extroverted) by the very nature of blogging.

    I blog, but I’m INTP/INTJ (seems to switch back and forth) according to various online tests. The “I” part (introversion) always gets a very high score. In general, introverts like being around people, but need time on their own to “recharge”. I find blogging takes less “social energy” than real-time discussion (face-to-face, phone, instant messaging).

    According to the test, my blog is ESTJ. I think that I also tended to be more introverted than extroverted. Blogging provides a way for me to personally reflect and digest information on my own before sharing it with others.

    I also think that I have a tendency more towards perceiving than judging. I think my natural personality would be ISTP, but my professional work tends to be very task and detail oriented, which forces me into a less natural pattern.

  3. Bob Carpenter Says:

    Nothing like a blog to turn up unclear writing. I just meant that blogs themselves are likely to be scored as extroverted (E), even if their authors aren’t. But then extroverted on the Myers-Briggs scale isn’t quite the same as the usual sense of the word in English.

    To show I was not only unclear, but wrong, Peter’s blog Apperceptual is classified by as INTP (which they dub “the thinkers”).

  4. Jason Adams Says:

    My blog comes up as ISTP, though I have tested consistently as INTP ever since high school. I talk about technology and my dogs a fair bit in addition to more science-y stuff, so maybe that triggered the S vs N difference.

    I just ran the urls for 65 of the blogs listed on the nytimes blogs page
    (62 from the times, 3 from the Int’l Herald Trib) through this.

    30 blogs are ESTP – these run the gamut – news, sports, living, arts
    another 25 blogs are ISTP – also news and sports and opinion.
    from this I conclude that blogging about the world is an STP thing.
    reporting that comes w/ analysis and opinions is labeled ISTP,
    otherwise, ESTP. for comparison, is ESTP, ISTP.

    2 blogs are ESTJ: bits and real estate q&a.
    1 blog is ISTJ: executive suite news. (as is slashdot, FWIW)
    2 blogs are ESFP: one travel, one fashion

    5 blogs are INTP: on the science side there’s dotearth and the evolutionary biology blog, and the tierneylab blog, on the arts side we get Stanley Fish and the great books reading group.

    only 1 blog gets the INTJ (Scientist) rating matching that of the LingPipe blog: the Herald Trib’s blog on globalization.

    who knew the Times had so many blogs?

    Hi there! I came across this post through my Google Alerts for the word “MBTI.” This may or may not be of interest to you, but I write a blog about the MBTI and wrote a post about how Typealyzer is basically junk. I know lots of people are checking it out for entertainment sake- and that’s totally cool…but I hope you don’t confuse those “blog type” results for your own personality type. Anyway, I won’t go into why the site is junk here, I just wanted to let you know if you wanted to learn more, here’s the original post:

    I also have a discussion in the comments section with the creator of the Typealyzer site.

    Great post!

    The thing to remember is that it isn´t actually supposed to analyze who the writer is (which I don´t believe in anyhow – neither by text classification or by using questionnaires), but determine the type of writing style. I´m ultimately interested in finding type related patterns in what people are interested in when in a certain persona. I believe we´re all changing between different personas that can be described by Myers-Briggs personality types and others type models – unless we´re psychologically maladapted in some way (autism, in a psychological state of chock etc).

    I´m very glad you brought up the question about extraversion/introversion and blogging! There are different interpretations of Jungs concepts. My take on it is that it´s about the focus of attention – the inner world of thoughts, feelings and reflections etc or the outer world of people and things. A text can be about the same thing (a blog post about the days events for instance) but still differ a lot in that regard. There are of course intelligent and experienced people with differing view on what Jung meant by it – but for my purposes I believe that interpretation is the best. ;-)

    Sounds like a neat project. My mom (Carol Carpenter) wrote her doctoral dissertation (from Wayne State University) circa 1988 on the relation between people’s personality style as defined by a subset of Myers-Briggs distinctions and the approach they took to writing (outline, just write from the top, revisions, etc.).

    And you’re right that the introverted/extroverted notion of Myers-Briggs isn’t the usual dictionary definition (that’s the danger of using common words for technical terms). But I’d still think that blogs by their nature would be extroverted even in the Myers-Briggs sense.

  11. Roberta Hill Says:

    Interesting stuff. I recently blogged about this blog post “The Most Common Myers Briggs Type on Twitter” ( But is even more fascinating. I entered my three blogs and three web sites and low and behold it came up INTJ and INTP evenly. I am an INTP but with a very low preference for the “P”. So my true nature shows up no matter what?

    I would disagree with your deductions that most blogs would be “E” preference based on their nature. This might hold true more with Twitter but the unscientific study mentioned above suggests that the most common is INFP. The I and E preference as pointed out above in MBTI is about source of energy. “I” preference would clearly find writing more energizing that public speaking for example.

  12. Janice Pence Says:

    That is too funny. Who would think that a blog has its own personality? But we do write our blogs so we would assume it would reflect who we are. I am an ISTJ and my writing definitely says who I am. I work hard to try to overcome thing and make my writing as vanilla as possible.

    Out of all of the Myers Briggs Personality Types – is there one that reads better? If there is please let me know!! I could use the help and my boss would appreciate it.

  13. lingpipe Says:

    Reads better as in it’s written so as to be easier (or some other -er) to read? I don’t know if any work’s been done in that area.

    My mom (Carol Carpenter) looked at the issue of writing style vs. MBPT for a couple of dimensions. It was in her Wayne State University Ed.D. dissertation circa 1987 — not available online as far as I know.
