I do apply it to myself, Naomi, most of the time. More often than most, hopefully, but like everyone else I am nowhere near perfect. I do, at least, try to get it right much of the time. That I got it wrong once (at least) does not change the fact either that I do use, or try to use, the scientific method most of the time, or that my argument in favour of scientific method is in general correct. Now move on and find a better argument, your constant use of tu quoque does you no credit.
