W.E. Demming is attributed to have said "In God we trust. All others must bring data". However, having spend 25 years in gathering and analyzing data, I know there can be bias in every step.
I also learned one other lesson. I don't have to perform an experiment my self in order to benefit from the outcome. I can learn from other's and it is a whole lot cheaper. Example in hand, this forum. I learn something everyday without performing any experiments.
What I am trying to say is we have choices. We can accept, question, perform our own, or ignore!
Great to have choices! Much better than the alternative!!!
