Zeida: Dr. Ladlow, a research psychologist, has convincingly demonstrated that his theory about the determinants of rat behavior generates consistently accurate predictions about how rats will perform in a maze. On the basis of this evidence, Dr. Ladlow has claimed that his theory is irrefutably correct. Anson: Then Dr. Ladlow is not a responsible psychologist. Dr. Ladlow' s evidence does not conclusively prove that his theory is correct. Responsible psychologists always accept the possibility that new evidence will show that their theories are incorrect. Anson bases his conclusion about Dr. Ladlow on which one of the following? ['the application of a general principle', 'the rejection of a theoretical explanation', 'the discrediting of facts', 'the use of an ambiguous term']
