Understanding sensitivity and specificity with the right side of the brain

Author of this article should be given a medal, failing that a big
pat on the back for making this concept so simple.

I have read about this subject every few months to make sure that I
do not confuse sensitivity with specificity. I have also hoped that if I
read about it often enough I will evetually understand it completely .
However the visual description has done for me what years of reading could
not do.
