No worries, I knew what you meant. I am pretty good at logic though, so no need to worry about illogical jumps here. I may not have very much background knowledge about terminology or history or science or anything (yet), and I may not be a very articulate writer (yet), but the one thing I can usually do very well is think clearly. I am even feeling a bit smug after finding the mammography Bayesian reasoning problem that apparently only 15% of doctors get correct to be easy and obvious. :)
