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.

(A) an attack on Dr. Ladlow¡'s character
(B) the application of a general principle

Anson conclusion : Dr. Ladlow is not a responsible psychologist.

The conclusion is based on the general principle "Responsible psychologists always accept the possibility that new evidence will show that their theories are incorrect. " It it stated in the stem that "Dr. Ladlow has claimed that his theory is irrefutably correct. " It means that Dr. Ladlow consider his theory flawless. Anson used this aboveforementioned general prinicple to conclude that Dr. Ladlow is not a responsible psychologist.
