Conviction
The Making and Unmaking of the Violent Brain
by Oliver Rollins
Biological explanations for violence have existed for centuries, as has criticism of this kind of deterministic science, haunted by a long history of horrific abuse and its influence over the theories of eugenics used by Hitler and the Nazi Party. Yet, this program has endured because of, and not despite, its notorious legacy. Today's scientists are well beyond the simplicity of the nature versus nurture debate. Instead, they assert that scientific progress has led to a belief in nature and nurture, biological and social, a stance that allows this science to supposedly avoid the pitfalls of the past. In Conviction, Oliver Rollins cautions against this optimism, arguing that the way these categories are imagined ignores a dangerous link between history and the present. The late 1980s ushered in a wave of techno-scientific advancements in the genetic and brain sciences. Rollins focuses on an often-ignored strand of research, the neuroscience of violence, which he argues became a key player in the larger conversation about the biological origins of criminal, violent behavior. Using powerful technologies, neuroscientists have rationalized an idea of the violent brain—or a brain that bears the marks of predisposition towards "dangerousness." Drawing on extensive analysis of neurobiological research, interviews with neuroscientists, and participant observation, Rollins finds that this idea of the brain is ill-equipped to deal with the complexities and contradictions of the social world, much less the ethical implications of informing treatment based on such simplified definitions. Rollins warns of the potentially devastating effects of a science that promises to "predict" criminals before the crime is committed, in a world whose understanding of violence is already influenced by prejudice and inequality.
