IS THIS UNUSUAL ? Yes, the vast majority of individuals are Left-Hemisphere dominant, and there is a considerable difference between the two... and this reality is only newly recognized with specificity that this site is providing to the public. Being quite new, very few individuals are aware of the facts discussed in this site, or what it means to be a R-Hd individual.
By way of contrast to this very familiar and majority based L-H polarity of the population, we have those who are R-Hd, and they have easy access to their MIND realms, their emotions, and they tend to be quite psychic. But they find it quite difficult to remember words, dates, or events... if these are not all part of an emotional experience the person has had... personally. The R-Hd individual is not at all good at the usual teaching of history, english, math, social studies, psychology, and many other courses where rote memory is the primary means of learning and testing.
