Maier's Law:
    If the facts do not conform to the theory, they must be disposed of.
    -- N. R. Maier, "American Psychologist", March 1960
Corollaries:
    (1) The bigger the theory, the better.
    (2) The experiment may be considered a success if no more than
    50% of the observed measurements must be discarded to
    obtain a correspondence with the theory.
