Stop right there! The author proceeds to compare the experimental methodologies of medicine et al. with physics. Uh uh. Sorry bub. It's not like you are proceeding in some parallel realm to physics composed somehow of fuzzy unknown blobs. Physics is the science of this world, and if you would be scientific, you must ground your findings in physics, through chemistry. Emulating its methods will not do.
You don't think that they are working through their clinical trials' findings with explanations in biochemistry, physiology, genetics and epigenetics? Isn't it called the Nobel Prize in Physiology or Medicine?
Did you read the article?
The author sheds interesting and valuable insight into the limitations of the “scientific method” and regression analysis in understanding of the human condition. It is certainly worth reading.
