If Psychological and Sociocultural Explanations Are to Make the Same

If psychological and sociocultural explanations are to make the same kind of progress in understanding schizophrenia that biological explanations have, then they must:

A) come up with more precise theories that explain how psychological and sociocultural factors contribute to schizophrenia.
B) rely exclusively on experiments to generate new knowledge within their disciplines.
C) acknowledge that biological explanations are the direction of the future and move on to other topics of study.
D) eventually merge with biological approaches, since they have difficulty explaining the causes of schizophrenia.
