“It is simply no longer possible to believe much of the clinical research that is published, or to rely on the judgment of trusted physicians or authoritative medical guidelines. I take no pleasure in this conclusion, which I reached slowly and reluctantly over my two decades as an editor of the New England Journal of Medicine” Dr. Marcia Angell, editor in chief, New England Journal of Medicine

"The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue. Afflicted by studies with small sample sizes, tiny effects, invalid exploratory analysis, and flagrant conflicts of interest, together with an obsession for pursuing fashionable trends of dubious importance, science has taken a turn towards darkness." 
Dr. Richard Horton, editor in chief of The Lancet; one of the worlds most well-respected medical journals 

Results of scientific research are whatever the researchers want them to be. He who pays the piper calls the tune.
