"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 analyses, 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 (top 5 most prestigious peer-reviewed medical journals in the world)
