There are many studies of early twentieth century on cranial forms and criminal behavior. Nowadays none is credible. One thing is the body and quite another is the mind. Via closed for some time.
If you're interested, look at early criminology studies until the middle of the last century. Maybe in forensic anthropology.
If we are fools or aggressive or potential criminals or great scientists, according to you the mind and body are coordinated. Please, there are very beautiful people with a superreformed mind and very ugly body people who are excellent people that I would like to look like to me, not of body, but of mind. Almost a century ago you saw that you did not have to see one thing with the other and you appear now with this coordination, read a little, study a little the bibliography that there is about all this. Please, if I feel a great person and do things to be happy and I am satisfied because I help, I feel good ... my nose will be perfect, my cheekbones prominent, my mouth perfectly delineated and my body with the super measures that have to be to be miss world. If I'm bad, it's going to be the opposite as a witch. The nervous system has nothing to do with all this. Please study what you need !
