an old paradigm cannot be replaced by evidence, facts or “the truth” … it will not be thrown out because its forecasts are wrong and its policies no longer work. An old paradigm will only be replaced by a new one when a group of maverick scientists orchestrate a coup and throw the old-school practitioners out of power.
