The human brain exhibits amnesiawhen called upon to reexperience the blows from sticks and stones. With humiliation and indignity, however, the brain is a steel trap of merciless memory.

It should come as no surprise that victims of hate crimes suffer greater emotional distress and cumulative psychological harm than victims of non-bias-motivated crimes. Indeed, five years after the traumatic encounters, they experience greater levels of depression and anxiety than other crime victims. The impact to both mind and body lingers much longer. The incidence of severe trauma from hate crimes requires a lengthier recovery periodif recovery is even possible at all.

Similarly, hate crime victims report that their reintegration into society is much more difficult to achieve. Deprived of self-respect after experiencing ordeals of indignity, victims of hate speech struggle with the everyday tasks of socialization. One obvious outcome is in trying to be less visible, which the hate crime victim achieves by moving to an entirely different environment.

In this way, hate speech serves to undermine free speech itself precisely because it silences the targeted group, compelling them to disappear socially.

Moreover, even watching someone else experiencing pain can create greater sensitivity in ones own pain perception. So finely calibrated is the processing of emotions in the human brain, it turns out that showing empathy to a fellow human being carries some emotional risk. In a 2009 study conducted simultaneously at the universities of Arizona and Maryland, researchers discovered that the anterior cingulate cortex, the region of the brain that regulates emotional reactions, responds to an emotional insult by unleashing a wide variety of physical responsesstress-induced sensations in the chest, muscle tightness, an increased heart rate, and stomach painsall triggered from the same sector of the brain. Another study undertaken by two professors from the University of Virginia in 2006 supported the finding that activation in the anterior cingulate cortex coincides with the onset of chest pains. The researchers concluded that emotional pain involves the same brain regions as physical pain, suggesting that the two are inextricably linked.

In fact, medical evidence abounds showing how emotion and physical harm share the same circuitry in the human brain. The New England Journal of Medicine published a research study in 2013 on how subjects experienced both physical and emotional pain by looking at a photo of a cherished person who died. Brain scans indicated the same neural activity when a subject was exposed to heat on his or her forearm as when shown a photo of a lost loved one. Experiencing physical pain did not yield a separate neural response that was distinguishable from emotional pain. A burned forearm and an aggrieved heart elicited identical neural reactions. One of the researchers on the study, Tor Wagner, a professor of neuroscience at the University of Colorado in Boulder, explained the reasons for this unexpected outcome, stating [t]hat may be why social pain is so painful: every time you remember it, you feel it all over again and that is not true for physical pain. Of all the things Ive observed in the brain, nothing is more similar to physical pain than social pain.

And the consequences of social pain are even more severe. The pain from social exclusion and indignity, which begins with emotional distress, ends up rendering a person physically sick. The two regions of the brain once thought to be the epicenter for the processing of physical pain show similar patterns of neural activity when the mind focuses on a photograph reminiscent of rejection or loss. A research team from the University of Kentucky set out to demonstrate this neural overlap between social and physical pain systems. Apparently, the same behavioral and neural mechanisms are at work in processing what many would believe to be disparate manifestations of pain. Psychology professor C. Nathan DeWall explained the significance of his teams findings in 2009: Social pain, such as chronic loneliness, damages health as much as smoking and obesity. We hope our findings can pave the way for interventions designed to reduce the pain of social rejection. He also speculated about the reasons why the human brain evolved in this manner. Instead of creating an entirely new system to respond to social hurt, he said, evolution piggybacked the system for emotional pain onto that for physical pain. The evolution of the human brain allowed emotional injury to take a free ride on the circuitry associated with physical pain.

And not surprisingly, when it comes to hate crimes and their origins in racial bigotry, the overall bodily damage arising from such injurious speech tends to be even worse. Law professor Richard Delgado noted that, [i]n addition to these long-term psychological harms of racial labeling, the stresses of racial abuse may have physical consequences. There is evidence that high blood pressure is associated with inhibited, constrained or restricted anger . . . American blacks have higher blood pressure levels, and higher morbidity and mortality rates from hypertension, hyper-intensive disease, and stroke than do white counterparts. Further, there exists a strong correlation between degree of darkness of skin for blacks and level of stress felt, a correlation that may be caused by the greater discrimination experienced by dark-skinned people.

Psychology professor Geoff MacDonald, from the University of Toronto, has charted the trajectory of bodily and psychological harm caused by social insult. He noted that, not unlike damage done to the body, the initial sensation of emotional hurt produces a surge of stress hormones. In the context of a physical injury, the purpose of this hormone is to brace the body for yet another attack. It provides confidence to both body and mind that the individual can actually take and survive a punch. The release of these stress hormones accounts for why a person can actually walk away on a broken leg or manage to speak despite having a shattered skull. After the surge of this energy dissipates, the pain ensues. The same release of stress hormones occurs when a person faces severe emotional, social pain. Proving the Talmudic injunction not to humiliate a fellow human being because it is tantamount to draining him of his blood, neuroscience can now account for how the ancients knew something about what happens, physiologically, to human beings who have experienced severe indignity. The brain discharges a sufficient amount of stress hormones to handle the first blow. When the damage is done and the insult has subsided, the body will begin the process of dissipating the pain, and the blood flows away from the afflicted area.

The difference, however, is that, unlike physical pain, where bones will ultimately heal, and the pain of the experience will become wholly forgotten, social pain can beand often isrelived over and over again. The sensation of the pain is instantly recalled and reexperienced. This is the consequence of how our memories cope with traumatic stress, resulting in a cruel admixture of the mind. Physical pain, by contrast, can be remembered as once being painful, but the pain itself cannot be reclaimed. The human brain exhibits amnesia when called upon to reexperience the blows from sticks and stones. With humiliation and indignity, however, the brain is a steel trap of merciless memory.

With sets of patients who had experienced physical injury and another group that suffered from emotional harm, researchers at Purdue University did a five-year study and checked back in with the participants each year after the incidents that caused them such pain. The focus of the study was to determine how they felt about what they had experienced five years earlier. The results, published in 2008, were not surprising to neuroscientists but surely would be perplexing to emotionally adverse judges. Those participants who had experienced emotional injury reported higher levels of pain than participants who experienced physical harm. They were still feeling the emotional effects of the harm. Psychology professor Kip Williams of Purdue stated that, While both types of pain can hurt very much at the time they occur, social pain has the unique ability to come back over and over again, whereas physical pain lingers only as an awareness that it was indeed at one time painful. A few law professors had been making similar points over the years, with much skepticism from their colleagues and the courts. It must have just seemed intuitively obvious. Arkes, for instance, once presciently wrote during the Stone Age of such speculations (in 1974), There is in fact such a thing as a psychological injury, which may be quite grave . . . as an assault on ones body or a broken leg.
