Previously the DSM has been accepted as the Bible of psychiatric diagnosis but, right before the DSM-V comes out the National Institutes of Mental Health (NIMH) has announced that it will not use it as a standard for diagnosis in their research. This means that they will not be funding studies that use the DSM-V as a diagnostic criteria. The reason given by the NIMH is that “Unlike our definitions of ischemic heart disease, lymphoma, or AIDS, the DSM diagnoses are based on a consensus about clusters of clinical symptoms, not any objective laboratory measure." This suggests a desire for exactness which the behavioral sciences have lacked relative to the physical sciences sometime termed physics envy.
