"The Nobel Prize-winning ethologist Konrad Lorenz used to recommend that every scientist discard at least one cherished notion every day, before breakfast. It is excellent advice (although Lorenz wasn't known for tossing away many of his own prized ideas). In any event, good science doesn't really require that its practitioners intentionally turn their backs on what they believe to be true, or what they devoutly wish were so. Tincture of time and the accumulation of new findings generally accomplish that: If we wait long enough, the world has a habit of making mincemeat of even our most strongly held ideas. The only thing necessary is to remain open to the evidence"
