Since you have made science a profession, I'm not surprised. Most people who have taken a year of college science could not design the simplest double blind experiment, nor could they tell you why the concept is important. I could say the same about most people practicing in the social sciences and psychology.
Not to mention nearly all the anti-evolution posters to these threads.
Including me ... but so what? I'm not afraid to admit that I *believe* in Creation as a matter of religious faith. It is part (not all) of the structure of what I believe as a Christian.
If something that I believe is literally true turns out to be false, then I was wrong. Big deal. My faith does not stand or fall on this point.
I'm not sure if I should admit this here but my training was in Psychology. Every one of my 'buds' in Psych did know what Dbl Blind is and why it is important.
Experimentation in Psych is much more rigorous than you may think. Psychological experimentation is constrained by its "subjects" you know.
