I have heard various theories regarding the correlation between socionic type and brain hemispheres. As most probably know, the left hemisphere is sequential, linguistic, and orderly, while the right hemisphere is holistic, spatial, and non-linear. I have heard some say that irrationals are right-brain thinkers, while rationals left-brain. I have heard another state that it had nothing to do with irrationality/rationality, but rather subtypes, stating that those with a judging function subtype will be left-brain, and a perceiving subtype will be right-brain. Are these theories most likely correct, or is it more complicated? Or is there, in fact, a correlation between brain hemispheres and socionic type, at all?
