Do I ever finish a part 2 for anything I write? I seem to remember having done so at least once, but nothing comes to mind.
Note that the following quote uses different terminology, but there can be no mistaking the correspondence. Somatotonic = mesomorphic (and viscerotonic = endomorphic).
Note: There is no direct antithesis to the V-11 trait. Somatotonic people, with their agoraphilia (claustrophobia, S-11) tend to develop spatial orientation to a high degree. Possibly it is as difficult to find a somatotonic who is spatially confused and has lost his way geographically, as to find a viscerotonic without friends to turn to for what he wants or needs. The kind of orientation an individual develops seems to depend upon his basic, constitutionally predetermined interests.
Varieties of Human Temperament
I had my suspicions before this, as mesomorphs tend to have greater will-to-power, sociopathy, and are generally “driven”. But then, that could be due to a number of things, including the tendency of muscles to increase one’s confidence (my “assume nature” mantra notwithstanding my relentless intellectual pessimism).
However…this spatial orientation aptitude maps precisely to the parietal lobe according to the melonhead theory without any obvious counterarguments (yet):
The parietal lobe integrates sensory information among various modalities, including spatial sense and navigation (See proprioception), the main sensory receptive area for the sense of touch (See somatosensation) in the somatosensory cortex which is just posterior to the central sulcus in the postcentral gyrus, and the dorsal stream of the visual system. The major sensory inputs from the skin (touch, temperature, and pain receptors) relay through the thalamus to parietal lobe.
I have not yet found convincing evidence for what we’re all guessing, which is that cros are endos and thals are ectos. But then, here’s a suggestive quote:
One further characteristic of visceratonia worthy of mention is the great rarity of suicide among persons in whom this component is predominant. We have looked as carefully as possible into the records of now over sixty suicides without yet finding a viscerotonic among the lot.
I have seen an argument suggesting that high waist:hip ratios would suggest thals were and are endos. But so far I am seeing a great deal of evidence to the contrary, suggesting that smart, fat men have impressive neocortices and tend to lack occipital buns. This also matches my magical neanderbrain intuition, which we all know is entirely infallible.
Edit: Excellent, turns out this book is available online for free. Though I prefer intuitionistic reasoning myself, I find their statistical approach much more useful than the slapdash approach of the other somatotyping book I’m familiar with.
