Burn him? Hang him? Or let him go? New research illuminates how the human brain decides the severity of a criminal’s punishment, scientists say.

Several brain regions do battle in determining the appropriate level of justice, depending on the person’s level of guilt, a study has found.

Often, people demand swift and severe punishment, particularly when the crime involves bodily harm to others and is relayed in gruesome detail. Yet certain brain regions can override this gut emotional response when the harm was not intentional, regardless of how shocking the incident was.

Left Brain, Right Brain: Facts and Fantasies

Handedness and brain asymmetry are widely regarded as unique to humans, and associated with complementary functions such as a left-brain specialization for language and logic and a right-brain specialization for creativity and intuition. In fact, asymmetries are widespread among animals, and support the gradual evolution of asymmetrical functions such as language and tool use. Handedness and brain asymmetry are inborn and under partial genetic control, although the gene or genes responsible are not well established. Cognitive and emotional difficulties are sometimes associated with departures from the “norm” of right-handedness and left-brain language dominance, more often with the absence of these asymmetries than their reversal.
