Five new books

I bought five new books yesterday:

1. Warum Spinat nur Popeye stark macht - Mythen und Legenden in der modernen Wissenschaft
2. Wer nichts weiß, muss alles glauben
3. Bildung braucht Persönlichkeit - Wie Lernen gelingt
4. Detektive in Weiß
5. Zahlenspiele in der Medizin - Eine kritische Analyse

I already read book 1 - it is pretty trivial. Mostly for people who haven't read similar books yet.

Book 2 is disgusting and childish, apart from a couple of interesting pieces of information.

Book 3 has been written for teachers. The author is Gerhard Roth, who edited the German edition of Eric Kandel's collection of essays on psychoanalysis vs. neurobiology. Could be interesting, but I am not that far yet.

Book 4 is very interesting, I was amazed at the fact that I made the correct diagnosis for case 1 (the anemia with diarrhea and other symptoms) after reading about the first couple of symptoms.

Book 5 - not read yet.

Two new books

Bought 2 new books today: "Endlich unendlich" and "Battle Hymn of the Tiger Mother". The latter book is a big pile of crap, absolutely boring. A crazy, single-minded mother who invests all her sparetime in making her daughters piano and violin players. As if these skills were needed these days, when computers can play music and the only thing a human must do is enter it. Her priorities in child education are absolutely wrong, IMHO. Children ought to be educated in such a way that they learn useful and/or interesting things depending on their individual personalities. Playing music is neither useful nor interesting, composing is the only useful and interesting thing about music.

Grades for the previous term

Noticed some of the professors have finally decided what grades to give me on the courses of the previous terms. Here they are:

  • Brain modelling: Excellent
  • Analysis of algorithms exercises: Excellent
  • Efficient programs: Excellent
  • Efficient algorithms: Excellent

Nice :) Now I have to find out how to print the reports...

Jungian personality type

I have read the INTP description at and come to the conclusion that the description of this type matches my own personality quite well. There are some points I am uncertain about, but most of what is written there fits.

It is interesting to see how long it took me to find out who I am. I was brought up to be a duty fulfiller, but I always believed I was something else. The external forces prevented me to discover how I actually function, as I had to do homework, prepare for exams and work on my magazine all the time. What I find curious is that I was so easily inclined to believe I'm ENTJ, as the first result of the Keirsey Temperament Sorter suggested in 2004. Probably I thought so because working on my magazine, I had been acting somewhat like an entrepreneur. It took about 1 year until I realized I was definitely not extraverted. Indeed most tests classify me as INTJ. One of the problems with the Jungian-style type classification systems, such as MBTI, however is that they are muddled with J and P in introverted personalities. Socionics has a different ordering of functions. Socionics INTj is the same as MBTI INTP. I had been wondering if I, in reality, was more like INTP already some years ago. Trying the functional analytical approach, I came to the conclusion that I was using introverted thinking far more than introverted intuition. (Strangely enough, I wrote an article about what I then thought to be my dominant function, introverted intuition, some years ago.) The test I took yesterday confirmed this.

At, the INTP description definitely matches me more than the INTJ description, but one cannot generalize here. At some other pages the INTJ description might match me more than INTP. I think that the Jungian-style function theory is muddled and therefore would like to propose my own personality classification. I omit the distinction of J and P, and propose the following eight personality types:

  • Introverted abstract thinker
  • Introverted abstract feeler
  • Introverted concrete thinker
  • Introverted concrete feeler
  • Extraverted abstract thinker
  • Extraverted abstract feeler
  • Extraverted concrete thinker
  • Extraverted concrete feeler

If somebody is an introverted abstract thinker (like me), this means that:

  • he uses introverted thinking, extraverted thinking, introverted intuiting, and extraverted intuiting, in an undefined order; and
  • he is, in general, introverted.

I believe it is not correct to assemble a list of 8 functions just based on the dominant and auxiliary functions, as the Jungian function theory does, where the last 4 functions are the complements of the first 4 ones and are only used unconsciously, as "shadow functions". I rather think that people use their dominant and auxiliary functions both introvertedly and extravertedly, while a clear tendency if the total person is rather introverted or rather extraverted can usually be observed, and that the usage of the other functions is undefined (and usually, but not always probably rather weak).

Jungian cognitive functions

In MBTI-related personality tests I usually score as INTJ. According to the definition of that type introverted intuition should be my dominant function, and extraverted thinking my auxiliary function. I doubted that, as I subjectively had the impression that I'm spending more time analyzing than speculating. Now I've finally found a test which does not measure preferences, but tries to measure actual functions. My results are:

extraverted Sensing (Se): unused
introverted Sensing (Si): limited use
extraverted Intuiting (Ne): excellent use
introverted Intuiting (Ni): good use
extraverted Thinking (Te): good use
introverted Thinking (Ti): excellent use
extraverted Feeling (Fe): unused
introverted Feeling (Fi): good use

So my strongest functions are introverted thinking and extraverted intuiting, which matches the INTP type (or INTj in Socionics). However, extraverted thinking and introverted intuiting are strong, too. This confirms my doubts about Jung's theory that if one of your four strongest functions is introverted X, then extraverted X is only a shadow function, which is not used consciously (and vice versa). Obviously I use both extraverted and introverted thinking, as well as extraverted and introverted intuiting. The fact that I use introverted feeling more than introverted sensing matches MBTI's INTJ type more than its INTP type. Extraverted sensing and extraverted feeling are not used at all, the first of which is why I don't do sports and the latter of which is why many people think I'm arrogant and rude.

Clearly this falsifies parts of Jung's function theory as well as MBTI. But it confirms what I was thinking about how my personality works.
