Query: Soft Science

First of all, I am not trained as a scientist, but this is "soft science" even to me. The premise that the heart is "a" or "the" center of human intelligence is interesting to consider, but the fact that the author emphasizes that all ideas are copyrighted to his company over and over leads one to wonder how much of the research results could be replicated. Wouldn't a true research scientist be trying to entice others to study the subject instead of trying to own it? Very few other sources of support for the theory are cited. I wish the data were more compelling, because it is an attractive theory.
