How Well Done Are MBTI Descriptions?

Since I used the CAPT site descriptions in my last two blog posts, I figured out that I could check if these descriptions also hold for real people. So I decided and try to do the same type of analysis for myself and my family.

Me, as an INTP (even though it is hard to judge myself):

  • to understand whatever phenomenon is the focus of their attention TRUE
  • want to make sense of the world TRUE
  • they often enjoy opportunities to be creative TRUE
  • logical HOPEFULLY TRUE
  • analytical TRUE
  • detached in their approach to the world DEPENDS
  • they naturally question and critique ideas and events TRUE
  • little need to control the outer world FALSE
  • often appear very flexible and adaptable in their lifestyle FALSE

Then my mother as an ENFP:

  • attention to the outer world of possibilities TRUE
  • excited by continuous involvement in anything new TRUE
  • experience a deep concern for people as well TRUE
  • interested in possibilities for people TRUE
  • energetic, enthusiastic people MOSTLY TRUE
  • lead spontaneous and adaptable lives PROBABLY FALSE

My sister as an ESTP:

  • enthusiastic attention to the outer world of hands-on and real-life experiences NOT SURE
  • continuous involvement in new activities PROBABLY FALSE
  • pursuit of new challenges POSSIBLY TRUE
  • logical and analytical in their approach to life TRUE
  • acute sense of how objects, events, and people in the world work TRUE
  • energetic and adaptable realists MOSTLY TRUE
  • who prefer to experience and accept life rather than to judge or organize it FALSE

And my father as an ISTP:

  • to understand how things and phenomena in the real world work so they can make the best and most effective use of them PROBABLY TRUE
  • logical and realistic people TRUE
  • natural troubleshooters TRUE
  • quiet and analytical observers of their environment TRUE
  • pursue variety and even excitement in their hands-on experiences PROBABLY FALSE
  • a spontaneous, even playful side TRUE
  • detached pragmatism TRUE

I think what this exercise is trying to tell me, is that I need to seriously reconsider the typing of my sister (I can't decide between ESTJ and ESTP, but I am leaning toward ESTP because she displays Ni, and no Ne). Besides, you know, that it is not such a bad indicator of the type. So I guess it is a good check to see how wrong did I go.

MBTI typing: Germany (Country) - ESTJ

Last time I was typing my own country. Let me now try to type the other countries where I lived. The first country that I have lived was Germany, and that was for the semester exchange during my undergraduate study. For disclaimer, I only lived there for 5 mounts and I am only aware of what Leipzig is like, so my typing can be very off the mark. But let me try anyway.

One of the first things that I noticed was, that Germany is very efficient. You know how people joke about it? Well, I don't know if they do where you come from, but I know they do in Slovenia. Well, it is all very true.

But surprisingly, it is not overly regulated (yes, Austria, I am looking at you). But the things that are regulated, are efficient and everybody seems to adhere to it. This was the only country where I never saw a person crossing at the red light.

While there was administration to deal with, it was manageable and it could be done in the afternoon.

So based on that, I would say that they have Te as pretty high. Also, the energy of the country was not Fe-like, but it was more Fi-like, which would confirmed this. I would describe the difference as the difference between acceptance and pressure. In the Fe like culture, it is easier to get into, because the people will generally want to actively invite you in. But on the other side, there is pressure. to conform to the many unwritten rules. As somebody with Fe as my inferior function, I can tell you that the pressure., once a person becomes aware of it, can be very real. The Fi culture on the other hand is not that active from the start, but I found them more tolerable to any difference.

Hard to make nay judgment on the Ti. It was a long time since I was there.

In this case their perceiving function is introverted. Now, did I notice more Ni or more Si there? I actually have a hard time deciding here. I would have to settle on Si, though I am not sure. The only reason being, that I did not really see much Se (but then I come from the culture, where Se is quite predominant), but I did notice some Ne. If Ne is in the first four functions, than that would make Si also one of the first four function.

But that makes me a little uncomfortable, since I imagine that in the Si country, there would be a lot more emphasis on the identity (there was some of that) or history (almost none of that).

Now, is Germany a ESTJ or a ISTJ country? Considering that I am that much more comfortable with the Te than Si, I would then say that they are most likely a ESTJ country.

So let me now compare this evaluation with the description from the CAPT site for ESTJ:

  • need to analyze and bring into logical order the outer world of events, people, and things NOT SURE
  • organize anything that comes into their domain TRUE
  • work energetically to complete tasks so they can quickly move from one to the next NOT SURE
  • current facts and realities TRUE
  • their thinking has pragmatic quality TRUE
  • take their responsibilities seriously TRUE

Well, overall, I guess this type does kind of fit them.

MBTI Typing: Slovenia (Country) - ISFP

Today I am going to try and type my own country. Which should be a lot weirder than it is. But let me try to put my thoughts in some sort of order.

I think that in Slovenia we don't have a lot of functions that we use in the healthy way. Our Si is very unhealthy, which could be seen in at least two points: one) we have no idea about our identity. The whole identification with the nation is non-existent. Second) we are using the past to try and hurt one another. For example, when people are attacking their political opponents, based on the world war 2 group mentality. And another one that I have just thought of is, that people expect that their actions are just going to be forgiven.

The one that I think we are relatively healthy with is surprisingly Se. Slovenia is known by their natural beauty. But that is not all, we not only have quite a lot of great sportsmen, considering the state of the professional sport in Slovenia. But even everyday people like to engage in the sport, from running, cycling to hiking and all sort of adrenaline sports as well. Not to mention, as lot of people like to eat, some putting emphasis on the quantity and some on quality, but I think most people would be said that they live to eat. Unlike me, who is clearly on the eat to live camp.

So is there any other perceiving function that could potentially work? I would like to say yes, but... our Ni is not that strong, even if we would really like to have it. The Ne could potentially be seen in the way that people learned to use their surrounding creatively, but I think that is our Se more than Ne. Simply because I don't really see other people see our future possibilities at all. So I am going to stick with the Se.

That would mean that our judging function is most likely an introverted one. So is my country more Fi-Te or Ti-Fe? Here it would be a harder to say. I am not entirely sure about it. I used to think that we had a strong Fe, but now that I am here in Austria, I am having my doubts. Here the whole society feels a lot more Fe than anything I have experienced in Slovenia. On the other hand, there is definitely an outside pressure in Slovenia, that is a lot more reminiscent of the Fe than of the Te.

Though now that I think about it, a lot of time people will use the letter of the law to put pressure on the people that they stand in their own way. So while the pressure might feel like Fe, I don't think it is actually Fe, now that I think about it.

So based on that, I would say that we are more of an Fi-Te society.

Since a couple of psychologists studied the culture and they found out that we are more introverted, that would make our stack Fi-Se-Ni-Te, and out type ISFP.

Based on the CAPT site the ISFPs are:

  • deep-felt caring for living things FALSE
  • a playful and sometimes adventurous approach to life MOSTLY TRUE
  • show their caring in very practical ways TRUE
  • warmth and concern are generally not expressed openly TRUE
  • quiet adaptability VERY TRUE
  • realism VERY TRUE
  • "free spirit" spontaneity (what does this even mean?)

While I am not that satisfied with the type, I think it is quite a good approximation to how they really are.

I Discovered Jupyter

When I have been writing about the MBTI data analysis, I was wondering if there is a better way to present what was I doing. But there is nothing that I found at the time, so I just continued to do, what I have done so far.

But I have to be honest, I doubt that most people would take the necessary the to try and figure out what I was doing. Which I fine, as I mostly did it for my learning.

But now I am taking a Data Mining course. Since I am at the economics and business university, they can not expect that people will be master programmers.

Well, at least we are programming, so that is a positive side.

So in order to make programming easier, they suggested Jupyter. Well, we can discuss if it actually makes programming easier. I think it might make it harder, because the linearity is lost and there can be a lot more problems with the variables.

But I have to admit that it is easier to read than the plain code. And this is one of the things that I am planing to use a lot in a future.

So I started a sort of github for my Data Analysis projects. Which you can find here. Since I imagine I am going to be mostly having small projects first, I decided to try to use Jupyter. And maybe this will make it readable enough, that some people might actually get something from it.

You can find the repository with data analysis here. Check it out.

My first MBTI typing: John Kennex (Almost Human) - ISTP

In order to try and practice my typing skills, I decided to try and see, if I am able to type some of the fictional characters. While I do that, I am going to try and show what information did I consider, partly because it is a nice record of how I am thinking at the time, and for the second one, because I don't really like to do it the way most other ones do. You know, when they just give examples of usage of functions and never explaining why this order or even why these functions.

John Kennex from Almost Humans

For my first one, I am going to be typing John Kennex from the series Almost Human. Simply because for some reason my brain decided that binging on the whole series is a good idea.

Because this sci-fi series concentrates on the differences between humans and machines (or synthetics, as they call them), a lot of this is concentrated on the feeling. Which is why for a first couple of episodes, I am been overconcentrating on the Fi vs. Fe difference. It was not an easy decision. I spend way to much time on this. On the end, I was not sure, but I was leaning more toward the Fi than Fe.

Things that went against Fe were the scene that he scared a child by stabbing his leg. His actions toward Dorian in the first episode or when Rudy went drinking with them was not what a strong Fe user would do. But that does not mean that he never shows it. He is actually good with people, knows when no to intrude on the date and so on. But at the same time, he seems aware of his feelings, he is better with people close to him and he does not have a strong outside reaction to his ex-girlfriend being behind the attack. Which could show stronger Fi, but on the other hand, some of these could also show the higher Te or Ti.

Also, for some reason I got the feeling, that he is quite strong Se user. He does not show the normal Ne jumps, he does not seems to be checking his inner library all the time. Also, he does not remind me of the couple of dominant Ni users that I know. But he does look at the environment to get ideas, and he seems to work best under extreme stress. Nardi did mention that Se types can experience flow while in stressful situations.

So then I tried to combine the two of them, and I got the most likely ESFP. The problem with this was, that as soon as I started to read the description, I knew this is not the right one.

Then I decided to rethink my thinking so far. I was much more confident in the Se, than in my Fi observations. But just to make sure, on how wrong track I was, I decided to check with the Keirsey's temperaments. I could almost immediately cross out the SJ (Guardians) and NF (Idealists). Between the SP (Artisans) and NT (Rationals), I felt that he was much closer to the SP than NT. SP means that Se is in the one of the first two functions, which means that here I seems to be on the right path.

In then read the descriptions of all the rest of the SP types. I could definitely see, that it is most likely the Se-Ti combination, since both ISFP and ESFP were so off the mark. But I could see quite a lot of similarities with both ISTP and ESTP. I thought the ISTP descriptions were a tiny bit more accurate, but not to the extent that I would be sure.

So in this case, I used to check, what is his weakness. The opposite of the first function, of the anima as the Jung calls it, is that weakness. So the opposite of the Se function would be Ni, and the opposite of the Ti would be Fe.

Now, I did not see much of indication, that Ni was posing much of the problem. On the other hand, I have already mentioned before, that sometimes Fe did pose some problems. Which would make his first function Ti, and as that a ISTP type.

Now to check if I was right, I am going to try and apply the A little bit of Personality Metodology, to see if I get the same result.

First one is the E vs. I dichotomy. It is whenever the person uses the inside or the outside information first. I don't know if it is because of the Karl Urban's playing, but every time he gets thrown a curveball, he pauses before reacting. I notice that first at the Are You Receiving? episode. He also is not very quick to change or at least show his change of opinions. So here I would say I more than an E.

The second is S vs. N or first focusing on the experience or concepts. He uses concrete stories to illustrate his thinking, be it the fishing story to Paige or the story about his father and dirty cops to Dorian. Also, when arguing about something, he uses experience to make his point. One of the most funny ones was, after he saw naked MX. When Dorian and him talked about the coach, it was shown that he goes from experience. So I would say here S.

The third one is T vs. F, or usage vs. meaning. I think he is more of a usage person. He goes through the memory retrieval because it holds information to his investigation. He says to Dorian to answer the help phones, because they might get information. I can't think of any instance, which would show him first attending to the meaning. So he is a T.

And the last is J vs. P or first acting or first observing. He is not the type that plans a lot, and he usually changes his actions based on the new information. No matter if he at that point believes it or not. So here I would say a P more than a J.

Since I got the same result with two different models, I am now mostly confident in my typing. I would say that John Kennex is an ISTP.

Working in Teams with Different Jungian Types

When I was presenting my seminar paper based on the Jung‘s functions, I could tell from the comments of my professors, that they considered the MBTI as mostly being used in the team creation. Apparently if you put different people in the same group, the results are usually more creative.

I just hope that they are not simply tucking the unrelated type in the group of mostly the same types. Which could easily happen on the higher levels of any job, as the higher the job is, the more likely the people there are from the same time. For example, a lot of managers of the biggest firms are ENTJ (Te-Ni) and a lot of solders are ISTJ (Si-Te).

But from my experience, this is the worst way of doing it. One person is not going to make a difference, if all the rest of the team is in one direction. It is just going to frustrate that person. The results (at best minimal) do not justify the frustration (a lot).

There was a study, that looked over the different software development groups to see how well they worked together. The teams worked relatively well, especially if they had a lot of Te-Ni or Ni-Te people in it. The people with Si-Te or Se-Ti combination worked well with them as well. But add people with Fe in the stack, the the team goes from being efficient to being a nice place to work in. Which hurt performance and disturbed the information flow.

Surprisingly, there was not a single person with Ne in the top of their stack involved with the study. I plan to rectify that now.

I liked working in the Toastmasters. At the start, I had the Fe type making sure, that I was starting to get included in the workings and invited me to go work for the board. Later on, I had a sounding board, with Ni in the stack (pretty sure it was not the first function), who provided the different structure to my thinking. And later on a Te-Si type, who went and actually made our ideas practical in the long run.

Toastmasters is quite an interesting experience in itself, to see the dynamics show themselves. For one, the Toastmasters is clearly a Fe-Si environment, but surprisingly, it does not attracts a lot of Fe-Si types. Which provides some interesting place for experimenting.

There were other environments, that I did not like as much. One was also an Fe-Si environment (I must be attracted to them is some way, now that I think about it), but it had a lot of Fe-dominant types. There, I had no idea what was I supposed to be doing all the time. It felt… stiff. I had a person, that I am sure had Fi and Se as the first function, running away in less than 2 weeks.

Also, I prefer to work not in the group, but with one other person. Probably because of the recent revelation about myself, that I don‘t like that the group moves at the speed of the slowest person. As least in a pair, there is just one person that moves that slow, and that person can always disconnect. While it is hard for the whole rest of the group to disconnect.

I am kinda sure that it is the Ti-Fe connection that makes me like that.

In pairs I work well with most people. Notice that I say here most, and not all. Not sure if most people work well with me. :)

I think that this is one of the subjects that needs more observation. I wonder what other things I am still going to learn that way.

The Recipe for the Hungarian Cake (Madžarica)

On my computer, I have found this recipe. I remember making it, even though I think I ended up eating it all myself. Which was probably not the most healthy thing to do.

Since I am cleaning my computer, I decided to write it up and post it, in case somebody else wants to make it as well.

And I apologize to my sister. She asked my to start including the times for all the recipes. But considering that I am not making it, I have no idea how long does it take. If I remember correctly, it took more than an hour.

Ingredients:

Dough

  • 600g of flour
  • 150g of butter
  • 2dl of sour cream
  • whole eggs
  • baking powder
  • 200g of sugar

Cream

  • 1l of milk
  • 300g of sugar
  • 8 spoons of flour
  • 2 spoons of cacao
  • 1 vanilla sugar
  • 200g of butter

Cover

  • 100g of chocolate
  • 80g of sugar
  • 60g of butter
  • little milk

Recipe:

  • Mix all the things for a dough, divide it into parts and flatten them. Then bake it 10-15 minutes on 180°C. Wait until cold.
  • Cook cream by adding everything but butter. After getting a little colder, add the butter
  • Make cover by cooking everything for the cover. I suggest water bath.
  • Put dough, cream, ... until you run out of dough. Put the cover on top of it. Cool it down before serving.

Why Daily Reporting Works and Why not Everybody should Use it

I have recently started a sort of implicit agreement with my sister. Well, I say implicit, it started as a joke and I am stubborn. It started with my sister being worried that I spend to much time with books and I will be asocial. I made a joke, that I will send her reports. And she replied that she doesn't mind.

Maybe on the second thought, it wasn't really implicit. :)

So it started that each day I send her a daily report of what I did as a social interaction. It could be a line, saying I had small talk with three people or longer descriptions of what I actually talked about.

Is it sad, that in the one week that I am doing this I realized, that I don't really have a lot of substantial socialization? And that so far I had written to my sister twice, that I had no social interaction with any human being?

Well, when I started doing it, I could always feel a pressure to go out on some sort of meetup or to talk to the people in my class, even if I was not in a mode. I even went and checked a Toastmasters meeting. And I finally brought into my consciousness why I actually left them.

On the other hand, I have a small feeling it is creating a similar pressure in my sister to actually read and reply. Which is a bit not good.

It is this pressure that makes this method work for people. Nobody wants to tell their family and friends that they had eaten that chocolate, had no socialization or masturbated again. Or whatever habit are you trying to either break or install. It is highly effective, as far as the methods go.

On the other hand, this pressure with produce stress. Stress will not end, until the new way becomes the new normal, and it is no longer stressful to do it. I don't think anybody would mind reporting if they are still breathing. Assuming the actions do become natural. Otherwise this will turn into the ever lasting stress, that will slowly kill you.

And the effect that this would have on the relationship with this person in hard to predict.

I would say, that as a short-term technique, this is a good way to help install habits, but I would not use it long term.

First Working Model for the MBTI Project

I have presented the model at the school for predicting the MBTI types. I am not yet satisfied with it, as it only have around 35% of getting it right. Which is still better than 6% it would get from guessing.

On the end, I only used one model, since I could not get any better results by using multiple ones. So I decided that in this case it would be better to simply use the a single one. It was also the only one, where when I did not see a bias on the predicted/true diagram.

Interestingly, all of them had the same type of bias. I have not figured out why.

Here is the code that I have used for building the final model.

    from sklearn.feature_extraction.text import CountVectorizer, TfidfTransformer

    dtfitted = model.fit(texts2, types2)

    #this part is just how I checked if it is a good model -> usually it is better to check with a different dataset than the one used to build the model
    predicted = dtfitted.predict(texts2)
    print(np.mean(predicted == types2))
    conf = sklearn.metrics.confusion_matrix(predicted, types2)
    plt.imshow(conf, cmap='binary', interpolation='None')
    plt.show()

The model with a very simple version of the program, where you can test your own type, can be found on the https://github.com/sarajaksa/schoolwork/tree/master/personalitytype.

How MBTI Can Help Us Understand Other People's Criticism

Reading today's self-help, it seems that criticism is becoming the number one negative thing. I mean, it is like the happiness is the ultimate goal, and anything that endanger it, short or long term, is an enemy. This is a notion that I don't really agree with.

Not only criticism helps us grow and become better. Not allowing to accept our critical side also means that one of our personality types function is going to become underdeveloped. And underdeveloped functions can mean that this function can sabotage our actions.

According to the Beebe's mode, the function dealing with the criticism is the 6th one. So the same one than our auxiliary, but with the different direction. For example, in my case, since I am an INTP, with Ne being my auxiliary, that would mean that my 6th function is Ni.

This function can be seen in what other people show criticism forward. I, as an INTP, am usually quite annoyed by people not realizing something. I detest the unwillingness to put together an energy to think and not just be an idiot. Which is what Ni function is really good at.

This is also the reason why I think that Sherlock from BBC Sherlock might be an INTP. He shows similar kind of reaction. Though in his case, I am not sure if his reaction is that he misses Ni in other people or Ti. Not like I can see into his head. But I favor the Ni for now.

On the other hand, my mother, an ENFP, usually criticize me based on what other people will think, which shows that she has a Fe at this place. Discussion whenever to wear a sweater in my household usually turned to her argument "what will people think".

My father has Si in this place, and he does comment on my, and sometimes my sister, how clumsy we are. He also comments on our laziness, which would also be a Si kind of criticism. Si simply continues to do, and does not want to stop. Laziness would go against that.

Or let us take the Fi on this position. John Watson for BBC Sherlock was a good example of that. The time he was most angry about Sherlock, was when he considered him breaking his morals, the so called vow. Holding his bleeding wife probably did not help him see what he was doing.

We could go through more of these examples. But the point I was trying to make this the following: We all have a function, which first gains the self-expression through the criticism. Without it, it can not express itself, and it will stay unconscious, instead of the tool to be used.
