I have a Ph. D. in experimental psychology from Cornell University. I started in physics, switched to psychophysics, and then to cognitive processes with special interests in human eye movements. I was a professor at Cornell, Cal Tech,and USC, was a senior fellow at the National Research Council of the National Academy of Sciences,and over the years became a research design methodologist for graduate students in the social sciences and engineering. My most recent interests are clinical trials of new technology medical devices--and just published a series of articles related to a device called a "vein viewer."
I've been participating in GHMB for quite a few years, beginning after I read, Fingerprints of the Gods by Graham Hancock. I've made only very limited comments in mysteries message board--the key board for most of the concepts you are discussing--unless they are AOM participating authors, like you. I usually am not well enough grounded in the relevant literature to be very helpful. I have kept up with quite a bit of the literature on native people in North America, and have interacted with some native people both here and in the foothills of the Himalaya mountains--especially the Hilltribe people bordering Burma, Thailand, Laos, and China. As a hobby, I sold arts and crafts from these regions to museum stores in the Southern California area.
I feel that people with my academic background are much more open to the so called "new age" books than many suppose. The archeologists you reference have a perspective on science that is very different from my way of thinking. I'm not comfortable with them using terms like "fringe," "woo," or "pseudoarcheology." On the other hand, though I'm open to almost any speculation, I usually have great difficulty crossing the bridge from interest to belief. Where an academic like me gets involved is when there is enough specific information to permit the creation of an experimental paradigm. Such a paradigm then requires one to gather and test specific hypotheses--and that doesn't seem to happen very often.
