Somatotype and Myers Briggs Typology

[psychdigg]

Edit by God: What this means

Ectomorphic: characterized by long and thin muscles/limbs and low fat storage; receding chin, usually referred to as slim.
Mesomorphic: characterized by medium bones, solid torso, low fat levels, wide shoulders with a narrow waist; usually referred to as muscular.
Endomorphic: characterized by increased fat storage, a wide waist and a large bone structure, usually referred to as fat.

I think there will be a positive correlation between body type and personality, but orientated towards the more archetypal traits.

Also, I believe this theory has greater correlation with the ennegram than Myers Briggs. For instance I am 8w7 and far more Mesomorphic, my INTJ is angled towards the "scientific combatant".

If you take the above theory and then overlay it with the mbti v ennegram like in this article http://www.breakoutofthebox.com/flauttrichards.htm then you will see its more archetypal.

Archetypal traits are the long tail (Prehistory) of human evolution which comprises far more biological evolution than the recent prominence of modern attributes (Linear thinking, less artisan etc etc etc).

However, looking more closely at the theory its pretty easy to deconstruct. Effectively F traits (more pronounced in women as shown in Mbti tests) are shown as leaning to Endomorphic (wider hips etc) whereas the T male traits lean towards narrower hips. Then you see the more sporty body types Mesomorphic being more outdoor/ extroverted / worker type with the Ectomorphic being more indoor / introverted / scientific types.

The biggest issue with the above paragraph is that invariably this is just a rough approximation of what is self evident through normal observation. The next question becomes one of the relative interplay between Nature and Nurture.. which I will call predeterminism... To follow.

"this is just a rough approximation of what is self evident through normal observation."

True. Personality IS fairly obvious if we look at people without the obstruction of our own preconceptions. We tend to buy into the "persona" which is the advertised personality rather than what is really in front of us. Even though there are just a few dimensions to personality the permutations of a few items can lead to significant differences and insights. We are not looking for the "little" things the "idiosyncrasies". It is the big things that break up marriages, lead to occupational problems and a breakdown in various negotiations. Here is another chart to ponder:



These somatotypes are all based on photographs that exposed enough of the subjects body to make it possible to somatotype them.

The question though, is how accurate is the correlation? and how can it be used in a manner better than what would appear to be more precise psychological assessments?

In terms of this predeterminism I mentioned earlier it appears that this type of body + psych profile follows a conditional probability type process, as nature and nuture generally positively reinforce each other. And perhaps of note is that while people wish to play on their attributes it would seem that their disadvantages are the determining factor. I can be Mesomorphic and be INTJ, but I don't think you could be Ectomorphic and ESTP as easily.

One thing that is evident even within traditional white collar environments (take financial services) you see body type + psych profile play out. Quite possibly Mesomorphic types have greater energy (as preconditioned for physical activity) which they need to expend and as such become the dynamic fast paced go getters (They enjoy fighting and the stressors it involves), while the Ectomorphic types have lower energy and thus accept clerking work (Avoiding stressors). But this is why I say this somatotype is more archetypal/enneagram than Mbti.

Perhaps one thing of useful note is that while extraverts supposedly are energised by extroversion, and introverts de-energised by the same. It is more than plausible that Mesomorphic types are energised by conflict whereas Ectomorphic are stressed by it (de-energised). These are reasonably similar concepts but not quite the same. Mesomorphic is about dominance (Conflict), Extroversion is not (Amimability) etc.

THE PROBLEM WITH PERSONALITY TESTS

What’s wrong with this scene?

You walk into a psychologists office and you ask him to help you get your life on track. Almost by habit, he reaches into his top right hand desk drawer and pulls out a folder with some forms and hands you a copy. It’s a questionnaire! Professionally, they are called “Self-Report Tests” (also referred to as “inventories” or “instruments”). There may be anywhere from 25 to a 100 or more responses required, and when the results are summed up and sorted out, your true self will be magically revealed to you. This routine has been going on for around 125 years. Various statistical methods (mostly factor analysis) have been developed to tease out significant relationships between the questions. The goal is to create a more accurate test, employing the words we commonly use to describe people (also called the lexical approach). Don’t bother asking the psychologist to guarantee that the horoscope-like description of you is really you.

Do you see the problem yet? The problem is that the test is asking YOU the questions. The answers come from, YOU, the very person who has been frustrated your whole life because YOU don’t have a clue about what kind of person YOU are. Suddenly, you are the expert that is supposed to know the precise meanings and implications of the various descriptive words, ideas and behaviors and in addition to that you are supposed to know exactly, the degree to which these words apply to you. You are supposed to rank the various descriptions, or assign some value on a scale of one to five to each item.

On top of that, remember, humans are very tricky when asked questions about themselves. Look up the etymology or historical background of the word “personality”. It comes from the word “persona”, which refers to the mask that actors wore in the ancient theater. Too often, our personality is what we want people to think we are or what we want to imagine we are. So we are deceptive in our social interactions and we tend to lie in varying degrees on psychological tests.

Then there is the question of how well people understand the descriptive terms used on a test. What’s the difference between “anger” and “frustration?” Or is there a difference between being “careful” and “cautious” or “fearful” and “worried?” We don’t have a dictionary in our heads, let alone a thesaurus.

It gets worse. What about the reliability problem? This has to do with the fact that people score differently when given the same test after a several month interval. The publishers of various tests boast about test-retest correlations between 70-90%. This would be considered “good” to “excellent.” But there is no way of knowing just how reliable a particular person’s ratings are without retaking the test. And if you do retake the test which score is the correct one? This means that there is a good chance that your health, attitude, anxiety level, amount of sleep, and/or personal problems will make your results inaccurate.

We haven’t even discussed the validity of what is being measured. Are the various types real? What are we talking about? Are we really explaining personality or are we presenting a model of how words commonly used to describe personality are related. Some tests might even be considered word usage tests more than personality tests. And finally, is this the best we can do after all of these years of research? There is the claim that the problems with self-report tests can be managed. That hardly inspires confidence. Management of tests merely adds another layer of things that have to be measured. What is clearly lacking is agreement on a general theory of the basic dimensions of personality.
