Psychologist: There are theories that posit completely different causal mechanisms from those posited by Freudian psychological theory and that are more successful at predicting human behavior. Therefore, Freudian theories of behavior, no matter how suggestive or complex they are, ought to be abandoned in favor of these other theories.

Which one of the following is an assumption on which the psychologist’s argument depends?


(A) Freudian theories have offered interesting suggestions, which have been shown to be false, about the causes of human behavior.

(B) A psychological theory with greater predictive success than another is scientifically preferable to it.

(C) Freudian theory has had little success in predicting how people will behave in various situations.

(D) Measuring the predictive success of a psychological theory involves considering other theories that attempt to explain the same phenomena.

(E) Scientific theories become impractical if they posit causal mechanisms beyond a certain level of complexity

+1 for B.

Conclusion:
In favor of theories that are more successful at predicting human behavior, Freudian theories of behavior(less successful) should be abandoned.

(B) A psychological theory with greater predictive success than another is scientifically preferable to it. --> Correct, negate the statement and see how it affects the aforementioned conclusion

Hence, B.

Approach -
1) Eliminate A, C, D and E. They do not require Freud theory to be abondaned or rejected in favor of other theories

Can you explain how to choose between B and C?

Hi!

Option C is the premise of the argument.
Read the first line of the argument.

An assumption is what links the premise to the conclusion. So, the assumption can neither be inferred from the premise or the conclusion.

Hope it helps.

The argument says that "other theories" are more successful in predicting than "F theory".
So, "F theories" should be abandoned.
Does this definitely indicate "F theory" is less successful than "other theories"?

Yes, if you assume the theories are used ONLY to predict human behaviour. Otherwise, it might be a yes-no answer and not definitive.

Overall less successful or less successful at predicting human behaviour. The aforementioned assumption makes things clear.

Hope this helps.
