I was a little surprised to see how many people in SCN hold a Phd. I tried to find in which field they are working, see my results below. Most results I got were from the personal COS-websites. As lostatsea mentions a lot (27) of them are chiropractors. I didn't even know what that was and had to look it up. Chiropractic is not taught in Dutch and Belgian universities, is not a medical specialty and belongs in those countries to the non-conventional or alternative medicine.
