Thanks for the question! So let’s take a look at (E). It tells us that psychologists who accept the possibility that new evidence will show that their theories are incorrect are responsible psychologists. That means
Accept possibility —> Responsible psychologists
What does Anson’s argument tell us? Anson says that responsible psychologists accept the possibility that new evidence will show that their theories are incorrect. In other words, if you’re a responsible psychologist, then you’ll accept the possibility. That’s
Responsible psychologists —> Accept possibility
So (E) is a mistaken reversal and incorrect. (B), on the other hand, follows the logic correctly.
Hope this helps! Feel free to ask any other questions that you might have.
