"A lot of what is published is incorrect."
"The case against science is straightforward: much of the
scientific literature, perhaps half, may simply be untrue.

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."
