Could Biologically Enhancing Our Morality Save Our Species?
As a species, we are prone to weaponizing. There is a famous anecdote from Wulf Schievenhovel, a German anthropologist who was working in the highlands of New Guinea studying a local tribe. One day, he offered two tribesmen a flight in an airplane. They duly accepted but showed up with two large stones. When he asked why, they told him that they wanted to drop them on a neighboring village. Ethologist Frans de Waal later remarked on this story that Schievenhovel had effectively "witnessed the invention of the bomb."
Today you don't have to be Putin or Kim Jong Un to pose an existential threat.
Modern technology has given us access to more than just rocks. In 2011, a Swedish man was arrested after attempting a nuclear fission in his kitchen. And in the inaugural issue of this magazine, my colleague Hank Greely raised a terrifying prospect:
"do-it-yourself hobbyists can use CRISPR [gene editing]… to change the genomes of whole species of living things – domestic or wild; animal, vegetable, or microbial – cheaply, easily, and before we even know it is happening."
In science fiction, it is typically governments that take over technologies and use them for evil. That risk is of course no fiction. It is an ongoing problem that we have addressed through institutions: democracies, constitutions, legal systems and international treaties, and groups working together as checks and balances. It isn't perfect, but it has worked (so far).
Today you don't have to be Putin or Kim Jong Un to pose an existential threat. We are rapidly acquiring the technological ability for individuals and groups not just to cause major harm, but to do so exactly as Hank said: "cheaply, easily, and before we even know it is happening."
How should we address this problem? Together with Ingmar Persson, a fellow philosophy professor at Gothenburg, Sweden, I have argued that while education, institutions and good policing are important, we may need to think more radically.
We could adapt our biology so that we can appreciate the suffering of foreign or future people in the same instinctive way we do our friends and neighbors.
We evolved, along with the New Guinea tribesmen, to care about our small group and to be suspicious of outsiders. We evolved to cooperate well within our group, at a size where we could keep an eye on free riders. And we evolved to have the ability, and occasionally the desire to harm others, but with a natural limit on the amount of harm we could do—at least before others could step in to prevent, punish or kill us.
Our limitations have also become apparent in another form of existential threat: resource depletion. Despite our best efforts at educating, nudging, and legislating on climate change, carbon dioxide emissions in 2017 are expected to come in at the highest ever following a predicted rise of 2 percent. Why? We aren't good at cooperating in larger groups where freeriding is not easily spotted. We also deal with problems in order of urgency. A problem close by is much more significant to us than a problem in the future. That's why even if we accept there is a choice between economic recession now or natural disasters and potential famine in the future, we choose to carry on drilling for oil. And if the disasters and famine are present day, but geographically distant, we still choose to carry on drilling.
So what is our radical solution? We propose that there is a need for what we call moral bioenhancement. That is, for seeking a biological intervention that can help us overcome our evolved moral limitations. For example, adapting our biology so that we can appreciate the suffering of foreign or future people in the same instinctive way we do our friends and neighbors. Or, in the case of individuals, in addressing the problem of psychopathy from a biological perspective.
There is no reason in principle why humans could not be genetically modified...to make them kinder, happier, more conscientious, altruistic and just.
We have been dramatically successful at modifying various moral characteristics of non-human animals. Over ten thousand years or so, we have turned wolves into dogs by selective breeding, and those dogs into breeds with behavioural as well as physical characteristics: certain breeds can be faithful, hard working, good tempered and intelligent (or the opposite). Scientists have manipulated the expression of genes in prairie voles to cause them to form a mate bond more quickly, and in monkeys to make them work harder. There is no reason in principle why humans could not be genetically modified using gene editing, or their brains modified in other ways, to make them kinder, happier, more conscientious, altruistic and just.
One objection is that this is a pipe dream: even if it is acceptable to do this, it is so unlikely to be achievable, it is not worth pursuing. However, research has shown that we are already morally modified. This is widely accepted when it comes to negative effects. For example, we all know that alcohol can lead people to aggressive or other destructive behaviours that they would not have countenanced sober. In a 2008 case, a retired UK teacher was cleared of child pornography charges after he successfully argued his behaviour was caused by a drug prescribed for his Parkinson's disease. There is also evidence that we can be morally modified in a more positive direction. For example, SSRIs like Prozac, a class of drugs widely used to treat depression, have been shown to act on healthy volunteers to make them more cooperative and less critical.
Another objection is that we need the negative aspects of our human character. We need people who can fight wars. We need to be able to blot out the suffering of the wider world: to experience it as we would if it applied to our nearest and dearest would be unbearable. This might be so. If aggressiveness and denial, or strong bonding to small communities, are important traits, it is important that we understand how, and to what degree, they should be controlled. It is unlikely that nature has dished out exactly the right levels of all morally relevant characteristics on an individual or population level. We don't claim to have all the answers to what characteristics we need to enhance, and what characteristics we need to diminish. But we see no reason to believe that the status quo is the optimum.
We haven't argued that we should go blindly in now with half-baked moral enhancers, or that we should forget about moral education, or legal solutions. Evolution has a built-in response to existential threats through adaptation. But adaptation takes generations and can't deal with threats that take out a whole population. Some threats are too important —and too urgent—to be left to chance.
When doctors couldn’t stop her daughter’s seizures, this mom earned a PhD and found a treatment herself.
Twenty-eight years ago, Tracy Dixon-Salazaar woke to the sound of her daughter, two-year-old Savannah, in the midst of a medical emergency.
“I entered [Savannah’s room] to see her tiny little body jerking about violently in her bed,” Tracy said in an interview. “I thought she was choking.” When she and her husband frantically called 911, the paramedic told them it was likely that Savannah had had a seizure—a term neither Tracy nor her husband had ever heard before.
Over the next several years, Savannah’s seizures continued and worsened. By age five Savannah was having seizures dozens of times each day, and her parents noticed significant developmental delays. Savannah was unable to use the restroom and functioned more like a toddler than a five-year-old.
Doctors were mystified: Tracy and her husband had no family history of seizures, and there was no event—such as an injury or infection—that could have caused them. Doctors were also confused as to why Savannah’s seizures were happening so frequently despite trying different seizure medications.
Doctors eventually diagnosed Savannah with Lennox-Gaustaut Syndrome, or LGS, an epilepsy disorder with no cure and a poor prognosis. People with LGS are often resistant to several kinds of anti-seizure medications, and often suffer from developmental delays and behavioral problems. People with LGS also have a higher chance of injury as well as a higher chance of sudden unexpected death (SUDEP) due to the frequent seizures. In about 70 percent of cases, LGS has an identifiable cause such as a brain injury or genetic syndrome. In about 30 percent of cases, however, the cause is unknown.
Watching her daughter struggle through repeated seizures was devastating to Tracy and the rest of the family.
“This disease, it comes into your life. It’s uninvited. It’s unannounced and it takes over every aspect of your daily life,” said Tracy in an interview with Today.com. “Plus it’s attacking the thing that is most precious to you—your kid.”
Desperate to find some answers, Tracy began combing the medical literature for information about epilepsy and LGS. She enrolled in college courses to better understand the papers she was reading.
“Ironically, I thought I needed to go to college to take English classes to understand these papers—but soon learned it wasn’t English classes I needed, It was science,” Tracy said. When she took her first college science course, Tracy says, she “fell in love with the subject.”
Tracy was now a caregiver to Savannah, who continued to have hundreds of seizures a month, as well as a full-time student, studying late into the night and while her kids were at school, using classwork as “an outlet for the pain.”
“I couldn’t help my daughter,” Tracy said. “Studying was something I could do.”
Twelve years later, Tracy had earned a PhD in neurobiology.
After her post-doctoral training, Tracy started working at a lab that explored the genetics of epilepsy. Savannah’s doctors hadn’t found a genetic cause for her seizures, so Tracy decided to sequence her genome again to check for other abnormalities—and what she found was life-changing.
Tracy discovered that Savannah had a calcium channel mutation, meaning that too much calcium was passing through Savannah’s neural pathways, leading to seizures. The information made sense to Tracy: Anti-seizure medications often leech calcium from a person’s bones. When doctors had prescribed Savannah calcium supplements in the past to counteract these effects, her seizures had gotten worse every time she took the medication. Tracy took her discovery to Savannah’s doctor, who agreed to prescribe her a calcium blocker.
The change in Savannah was almost immediate.
Within two weeks, Savannah’s seizures had decreased by 95 percent. Once on a daily seven-drug regimen, she was soon weaned to just four, and then three. Amazingly, Tracy started to notice changes in Savannah’s personality and development, too.
“She just exploded in her personality and her talking and her walking and her potty training and oh my gosh she is just so sassy,” Tracy said in an interview.
Since starting the calcium blocker eleven years ago, Savannah has continued to make enormous strides. Though still unable to read or write, Savannah enjoys puzzles and social media. She’s “obsessed” with boys, says Tracy. And while Tracy suspects she’ll never be able to live independently, she and her daughter can now share more “normal” moments—something she never anticipated at the start of Savannah’s journey with LGS. While preparing for an event, Savannah helped Tracy get ready.
“We picked out a dress and it was the first time in our lives that we did something normal as a mother and a daughter,” she said. “It was pretty cool.”
A sleek, four-foot tall white robot glides across a cafe storefront in Tokyo’s Nihonbashi district, holding a two-tiered serving tray full of tea sandwiches and pastries. The cafe’s patrons smile and say thanks as they take the tray—but it’s not the robot they’re thanking. Instead, the patrons are talking to the person controlling the robot—a restaurant employee who operates the avatar from the comfort of their home.
It’s a typical scene at DAWN, short for Diverse Avatar Working Network—a cafe that launched in Tokyo six years ago as an experimental pop-up and quickly became an overnight success. Today, the cafe is a permanent fixture in Nihonbashi, staffing roughly 60 remote workers who control the robots remotely and communicate to customers via a built-in microphone.
More than just a creative idea, however, DAWN is being hailed as a life-changing opportunity. The workers who control the robots remotely (known as “pilots”) all have disabilities that limit their ability to move around freely and travel outside their homes. Worldwide, an estimated 16 percent of the global population lives with a significant disability—and according to the World Health Organization, these disabilities give rise to other problems, such as exclusion from education, unemployment, and poverty.
These are all problems that Kentaro Yoshifuji, founder and CEO of Ory Laboratory, which supplies the robot servers at DAWN, is looking to correct. Yoshifuji, who was bedridden for several years in high school due to an undisclosed health problem, launched the company to help enable people who are house-bound or bedridden to more fully participate in society, as well as end the loneliness, isolation, and feelings of worthlessness that can sometimes go hand-in-hand with being disabled.
“It’s heartbreaking to think that [people with disabilities] feel they are a burden to society, or that they fear their families suffer by caring for them,” said Yoshifuji in an interview in 2020. “We are dedicating ourselves to providing workable, technology-based solutions. That is our purpose.”

Wanting to connect with others and feel useful is a common sentiment that’s shared by the workers at DAWN. Marianne, a mother of two who lives near Mt. Fuji, Japan, is functionally disabled due to chronic pain and fatigue. Working at DAWN has allowed Marianne to provide for her family as well as help alleviate her loneliness and grief.Shota, Kuwahara, a DAWN employee with muscular dystrophy, agrees. "There are many difficulties in my daily life, but I believe my life has a purpose and is not being wasted," he says. "Being useful, able to help other people, even feeling needed by others, is so motivational."
