Law, psychology, and the "new sciences": rethinking mental illness and dangerousness

Clinical and legal research on the meaning of mental illness and on definitions (and predictions) of dangerousness continue to offer the mental health law arena mostly disappointing results. In this article, the authors argue that much of this failure is linked to the prevailing Newtonian paradigm of cause-effect relationships, linear logic, and absolute order. In its place, the authors draw attention to the "new sciences"; that is, advances generated from quantum physics and chaos theory. To situate the analysis, the authors explore how psycholegal decision making unfolds. Specifically, the authors examine what contributions the new sciences offer society on the nature and meaning of psychiatric disorder and on the forecasting of violence. Along the way, the authors suggest how the new sciences advance the regard for citizen justice within the domain of mental health law.
