There is an area at Harvard that contains Phd research papers and it is extensive. These really humble you when you claim to have done research on a particular subject. Unless you devote a significant portion of your time to this kind of research you are probably very opinionated and accept your opinions as reality and therefore you've already started out on a contaminated conclusion basis. Over time I have only seen a couple of responses in the of postings on TOTV that may qualify as valid "Research Studies".
