Tudor's comment that "Kahler's argument is an example of a 'self-sealing doctrine' ... and as such, simply needs to be dismissed as defensive and unscientific" (p. 44) in reference to my 1975 statement that "in order to suggest there are other behaviors that are distinct from these five, a person would first need to be very knowledgeable in terms of identifying each (driver) as I have labeled it" (pp. 426-427). "Defensive"? My statement was definitive, not defensive. More than a dozen books have been written on my process communication model (PCM), mostly by authors who first received extensive training in PCM (100+ hours) and who also asked me to review, comment on, and authenticate the accuracy oftheir presentations. Some oftheir views differed from mine, and upon objective analysis, their suggestions were often valid and helped further clarify the model. I welcomed the additions by those knowledgeable authors. "Unscientific"? With my model's research findings over the last 35 years, I have been fortunate to be able to provide and support factually and statistically government-funded and university research projects, as well as 20 dissertations and 10 theses from major universities, all done by reputable and ethical researchers accepted by their academic communities. These universities considered these works sufficiently scientific to bestow on their authors-some 30 behavioral scientistsdoctoral and master's degrees. Each of these authors was appropriately well trained in my material by me personally or by one ofour PCM master trainers to ensure accuracy ofdefinitions and content and in order to undertake such rigorous research, which would forever be quoted in legitimate, scientific, and academicjournals. PCM has passed the highest ofexperimental design standards and, as a result, was the model of selection and placement of U.S. astronauts at NASA from 1978 to 1996. In fact, in 1980 NASA helped fund our Personality Pattern Inventory research validation studies that correlated drivers to my six personality types and miniscript distress sequences of scripts, injunctions, roles, rackets, games, myths, and impasses. As a result, we now have a database of700,000 profiled individuals worldwide, 17,000 for clinical purposes. Currently, Dr.
