Description:
<p>Psychiatry’s failure to validate its diagnostic constructs is often attributed to the prioritizing of reliability over validity in the <italic>Diagnostic and Statistical Manual of Mental Disorders</italic> (<italic>DSM</italic>).

I argue that the Research Domain Criteria (RDoC) framework, a new paradigm for classifying objects of psychiatric research, solves some of the challenges brought on by this assumption.</p>
