“Cruelty is surely the very worst of human sins. To fight cruelty, in any shape or form – whether it be towards other human beings or non-human beings – brings us into direct conflict with that unfortunate streak of inhumanity that lurks in all of us.” – Jane Goodall (2010: 306)
On May 13, a 39-year old Honduran father named Marco Antonio Muñoz was found dead on the floor of a padded cell in a Texas jail. Muñoz reportedly “lost it” the previous day after U.S. Border Patrol agents apprehended his family and physically removed his 3-year old son from his arms, leading agents to place him in isolation. The details of the tragic suicide are gruesome and indicate that having his son taken from him was the final straw for Muñoz, whose family had undergone tremendous stress prior to crossing the border. A Honduran consul revealed that one of their family members had been killed, leading them to decide to flee and seek asylum in the United States. They did not find the relief they sought.
The Muñoz family was likely unaware of the recently adopted “zero tolerance” policy for all undocumented border crossings, where children would be separated from their parents regardless of whether they were claiming asylum. Just six days prior to Muñoz’ suicide, Attorney General Jeff Sessions announced the policy in Scottsdale, Arizona, framing it somewhat ambiguously by mentioning the “smuggling” of children. Yet it was also clear that he meant for this to be a deterrent to parents, as they would have their own children taken from them:
“If you are smuggling a child, then we will prosecute you and that child will be separated from you as required by law. If you don’t want your child to be separated, then don’t bring them across the border illegally.” (emphasis added)
Several advocacy groups immediately denounced the policy as cruel and inhumane, including Amnesty International, the ACLU, and the Women’s Refugee Commission. The group Kids in Need of Defense stated that in addition to being cruel, the policy would make it more difficult to process cases for families who are seeking asylum from violence, since it is harder to get information from parents and children who are kept in separate places.
Since that time, more than 2,300 children (including infants) have been separated from their parents on the southern border. Clandestinely recorded audio of ten young Central American children crying for their parents while being held in a Customs and Border Protection facility has made their suffering visible and unavoidable. International outrage and condemnation has grown, from the United Nations to Pope Francis, over what most people understand intuitively – that child separation is cruel and inherently harmful.
“Cruelty is the Point”
When President Trump’s Chief of Staff, John Kelly, was asked about whether he thought it was cruel and heartless to take a mother away from her children, he replied, “I wouldn’t put it quite that way. The children will be taken care of — put into foster care or whatever.” Kelly is an alumnus of UMass Boston, where I have taught since 2003. I think he is an intelligent person, but this seems to be feigned ignorance. All he would have to do is take a moment to imagine a young child being separated from their parents — perhaps imagining himself as a boy in Brighton, or thinking of his own children being taken away when they were young. I’m sure he would quickly conclude that this would be a difficult experience.
Kelly seemed to be saying that children would be cared for and not put in any physical danger, though that does not always seem to be the case. During the Obama administration, some unaccompanied children who were placed in foster care ended up in the hands of human traffickers, indicating that procedures were “inadequate to protect the children in the agency’s care.” Also, the ACLU reported that unaccompanied immigrant children who were detained by U.S. Customs and Border Protection faced “pervasive abuse and neglect,” as well as denial of basic health care and being unallowed to move freely for days. For its part, the CBP denied the allegations (though there were 30,000 pages of them). Deportations during the Obama administration also led to thousands of children being separated from their parents as well, and many children have arrived at the border unaccompanied by an adult, so children being apart from their parents is not entirely new. What is new is the deliberate separation by U.S. officials at the border, creating a problem where there was none.
Even without being outright abused, neglected, or lost, there is good reason to believe that parent-child separation (including infants as young as a year old) is inherently harmful, and could reasonably be called cruel. Two UCLA professors, Jaana Juvonen (a developmental psychologist), and Jennifer Silvers (a developmental neuroscientist) even argued that forced separation qualifies as torture. Matt Yglesias wrote that “The reason we know it’s cruel — and the reason we know Kelly knows it’s cruel — is that the cruelty is the point.” After all, that is why separation is a deterrent. A year ago, when Kelly first publicly floated the idea of parent-child separation, he acknowledged that deterrence was the objective because no parent who loved their child would want to see them taken away. As an analogy, the Russian-American journalist Masha Gessen referred to recent examples of Russian police detaining children who protested against Vladimir Putin as a form of “hostage-taking” meant to leverage some political objective:
“Hostage-taking is an instrument of terror. Capturing family members, especially children, is a tried-and-true instrument of totalitarian terror. Memoirs of Stalinist terror are full of stories of strong men and women disintegrating when their loved ones are threatened: this is the moment when a person will confess to anything.”
Child Separation and the Biology of Trauma
Days ago, Secretary of Homeland Security Kirstjen Nielsen defended the policy of child separation, stating that “We operate according to some of the highest standards in the country. We provide food, medical, education, and all needs that the child requests” (emphasis added). However, these needs are insufficient, and the one obvious need that will not be met anytime soon is reunification with their parents. Few could deny that parental-child separation inflicts suffering. A year ago, when rumors of the separation policy were leaked, the American Academy of Pediatrics released a statement against it, noting that it would cause additional pain for children:
“Pediatricians work to keep families together in times of strife because we know that in any time of anxiety and stress, children need to be with their parents, family members and caregivers. Children are not just little adults and they need loved ones to comfort and reassure them.
Federal authorities must exercise caution to ensure that the emotional and physical stress children experience as they seek refuge in the United States is not exacerbated by the additional trauma of being separated from their siblings, parents or other relatives and caregivers. Proposals to separate children from their families as a tool of law enforcement to deter immigration are harsh and counterproductive. We urge policymakers to always be mindful that these are vulnerable, scared children.”
There is some evidence that these traumatic experiences can have long-term effects. Viet Thanh Nguyen, a professor at the University of Southern California, described his own experience as a 4-year-old child who was separated from his family at the end of the Vietnam War. Nguyen wrote that “Memory for me begins here, howling with fear and pain as I was taken from my mother, too young to understand that I would be returned to her in a few months.” He added that:
“[B]eing separated from my parents hurt enough for me to remember it vividly more than 40 years later. I can easily imagine the kind of damage a prolonged removal, under much more adverse circumstances, would do to a child. Or to a parent, since I am now the father of a 4-year-old myself. I say I can imagine it, but the pain of losing my son is actually unimaginable.”
Like Nguyen, I don’t think I can fully comprehend how hard it would be to have a child taken from me. On an emotional level, I think the closest word to describe how I would feel would probably be “anguish” for my child’s pain, and probably anger toward the people who caused it. On an intellectual level, I think most of us would probably feel this way, and I think I know why. Forgive me, but I cannot help but to view all of this at least partly from the perspective of a biological anthropologist.
Perhaps this is going back one step too far, but I think it’s important to remember that some of the hallmarks of being human are (1) our obligatory sociality, and (2) the intensity of the parent-child bond. Connections are essential, as none of us is an island. For example, large epidemiological studies show that strong social relationships are a better predictor of longevity among the elderly than whether one is obese or exercises regularly (Holt-Lunstad et al. 2010). Similar patterns have also been found in baboons, where females who had stronger and more stable social bonds lived longer (Silk et al. 2010).
This makes sense, as nearly all primate species are group-living and intensely social. The neurobiologist Matt Lieberman argued that we are “wired to connect” socially because this carried evolutionary benefits that enhanced our ancestors’ chances for survival, and that this goes deep into our primate and mammalian heritage. However, there are also costs to being so heavily invested in others, such as the potential for loneliness, isolation, neglect, ostracization, bullying, rejection, and loss. Furthermore, social pain is real, and it overlaps neurologically with physical pain:
“Throughout our lives, we are destined to experience different forms of social rejection and loss… Such breakups often feel unbearable, and they can dramatically alter how we view ourselves and our lives for a long time after. Our Faustian evolutionary bargain allows us humans to develop slowly out of the womb, to adapt to specific cultures and environments, and to grow the most encephalized brains on the planet. But it requires us to pay for it with the possibility of pain, real pain, every time we connect with another human being who has the power to leave us or withhold love. Evolution made its bet that suffering was an acceptable price to pay for all the rewards of being human.” (Lieberman, 2013: 69-70)
If such connections are important for older primates – including humans – with a lifetime of experience behind them, then they are even more important for the young and vulnerable. Primates tend to have singleton births (one at a time) instead of litters of offspring, and they are altricial at birth (highly dependent), requiring years of care. As mammals, they require nourishment from their mother’s breastmilk. And they also require a feeling of security, as Harry Harlow famously demonstrated decades ago. In Harlow’s experiments with infant rhesus macaques (monkeys), they were given a choice of surrogate “mothers” – one made of wire that provided milk, the other covered in soft terry cloth but provided no milk. Infants spent up to eighteen hours a day with the terry cloth surrogate mother, an indication that for young monkeys attachment and security were equally as important as nutrition, if not more so.
Harlow also completely isolated infant monkeys for lengthy durations, some for 3, 6, or 12 months (Harlow et al 1965). Among the eighteen infants, they showed an array of behavioral problems, including anorexia, self-clutching, aggression, fear, and stunted sexual development. The ones who were isolated the longest fared the worst; Harlow et al wrote that “12 months of isolation almost obliterated the animals socially” (p. 94). Isolated monkeys did not learn as well as controls, but due to the small sample size, this was not statistically significant. They noted that “we can, however, state with confidence that the ‘intellectual mind’ is far less crippled than the ‘social mind’ by prolonged total social deprivation if adequate experience is provided subsequently” (p. 95).
Of course, children are not monkeys. But there are lessons we can draw from other species. The Central American children separated from their parents will not be completely isolated as Harlow’s monkeys were. Nor will they be isolated for months. Still, there is evidence that even brief maternal separation in young mammals can be detrimental. In a recent study, Sarine Janetsian-Fritz and colleagues removed 9-day old rats from their mothers for 24 hours (Janetsian-Fritz et al 2018). They found that even this brief, but stressful, separation had long-lasting behavioral and physical effects, including mild memory impairment, less communication between brain regions, suggesting “increased probability of developing psychopathology later in life.” In another study, young infant rats that received less care and grooming from their mothers were more fearful and anxious. These effects were lifelong and were caused in part by epigenetic changes to genes affecting their glucocorticoid receptors (Weaver et al 2004). Similarly, maternal-infant separation also affected the epigenome in rhesus monkeys, with different amounts of DNA methylation in both prefrontal cortex and T cells (Provençal et al 2012).
In children, neglect and a lack of adult attachment in infancy have been associated with a range of developmental delays. Institutionalized Romanian children who lacked attachment with an adult since infancy showed delays in cognitive function, motor development, language, as well as socio-emotional behaviors. They also had more psychiatric disorders and altered EEG patterns. Fortunately, some of these deficits were reversible if children were placed into quality foster care at younger ages within a critical age of development.
However, for children who face a range of adverse experiences, some effects can last for a lifetime. In one sample of 132 older adults (average age of 69), adverse childhood experiences – including abuse, loss of a parent, or lack of at least one close relationship with an adult – were correlated with a range of physiological effects including shorter telomeres, which is associated with premature aging (Kiecoty-Glaser et al 2011). British and Finnish children who were evacuated to safer areas during World War 2, but who were separated from their families, grew up to have higher risk of depression and clinical anxiety (Pesonen et al 2007; Rusby and Tasker 2009), and a higher risk of cardiovascular disease and type 2 diabetes (Alastalo et al 2009).
The deliberate separation of children from their parents seems cruel and unnecessary in the immediate term. In the long-term, it has the potential for negative effects on health and biology, particularly if separated at younger ages. In fact, an online petition from the group Concerned Scientists on Migrant Child Separation has compiled a more complete list of the traumatic effects of early child separation and called for an end to the policy. Some children from Central America may arrive already unaccompanied, without a parent present. I imagine that deciding to send a child alone was very difficult, and in most cases is probably a sign of desperation. There is no need to add to the problem. There is also a legitimate fear that in some cases separations may be permanent, further exacerbating things. Additionally, the UNHCR reminds us that “seeking asylum is not illegal under international law and people have a right to be treated humanely and with dignity.”
Finally, to return to Viet Thanh Nguyen, he concluded his essay by wondering aloud what it says about a powerful country like the United States that it is willing to inflict suffering on poor parents and children arriving here:
“I wonder whether whoever decided to take me from my mother considered her pain. Maybe they only saw her alienness and her lack of education, which happened because she was born poor and a girl. Perhaps they never saw that in Vietnam she had been a successful businesswoman. But even if she hadn’t, what difference should that have made? Are people who are less successful not human or deserving of the right to hold on to their children? Our answer to that question says everything about us.”
