Why the Panic Over "Designer Babies" Is the Wrong Worry

BIG QUESTION OF THE MONTH: Should we use CRISPR, the new technique that enables precise DNA editing, to change the genes of human embryos to eradicate disease--or even to enhance desirable traits? LeapsMag invited three leading experts to weigh in.
CRISPR is producing an important revolution in the biosciences, a revolution that will change our world in fundamental ways. Its implications need to be discussed and debated, and not just by scientists and ethicists. Unfortunately, so far we are debating the wrong issues.
Controversy has raged about editing human genes, particularly the DNA of embryos that could pass the changes down to their descendants. This technology, human germline editing, seems highly unlikely to be broadly available for at least the next few decades; if and when it is, it may well be unimportant.
Human germline editing is unlikely to happen soon because it has important safety risks but almost no significant benefits.
Human germline editing is unlikely to happen soon because it has important safety risks but almost no significant benefits. The risks – harm to babies – are compelling. We care a lot about babies. A technology that worked 95 percent of the time (and produced disabled or dying infants "only" five percent of the time) would be a disaster. Our concern for babies will lead, at the least, to rigorous legal requirements for preapproval safety testing. Many countries will just impose flat bans.
But these risks also have implications beyond safety regulation. For this technology to take off, physicians, assisted reproduction clinics, and geneticists will have to be willing to put their reputations – and their malpractice liability – on the line. And prospective mothers will have to be willing to take unknown risks with their children.
Sometimes, large and unknown risks are worth taking, but not here. For the next few decades, human germline editing offers almost no substantial benefits, for health or for enhancement.
Prospective parents already have a tried and true alternative to avoid having children with genetic diseases: preimplantation genetic diagnosis (PGD). In PGD, clinicians remove cells from three- to five-day-old embryos. Those cells are then tested to see which embryos would inherit the disease and which would not. This technology has been in use for over 27 years and is safe and effective. Rather than engaging in editing an embryo's disease-causing DNA, parents can just select embryos without those DNA variations. For so-called autosomal recessive diseases, three out of four embryos, on average, will be disease free; for autosomal dominant diseases, half will be.
Only a handful of prospective parents would need to use gene editing to avoid genetic disease.
Couples where each has the same recessive condition (cystic fibrosis) or where one of them has the terrible luck to have two copies of the DNA variant for a dominant disease (Huntington's disease). In those cases, the prospective parents would need to stay alive long enough to be able, and be sufficiently healthy to want, to have children. In a world of 7.3 billion humans, there will be some such cases, but they will probably be no more than a few thousand – or hundred.
People are also concerned about germline editing for genetic enhancement. But this is also unlikely anytime soon. We know basically nothing about genetic variations that enhance people beyond normal. For example, we know hundreds of genes that, when damaged, affect intelligence – but these all cause very low intelligence. We know of no variations that non-trivially increase it.
Over the next few decades, we might (or might not) learn about complex diseases where several genes are involved, making embryo selection less useful. And we might (or might not) learn about genetic enhancements involving DNA sequences not typically found in prospective parents and so not available to embryo selection. By that time, the safety issues could be resolved.
And, even then, how worried should we be – and about what? A bit, but not very and not about much.
"The human germline genome is not the holy essence of humanity."
The human germline genome is not the holy essence of humanity. For one thing, it doesn't really exist. There are 7.3 billion human germline genomes; each of us has a different one. And those genomes change every generation. I do not have exactly the same genetic variations my parents received from my grandparents; my children do not have exactly the ones I received from my parents. The DNA changed, through mutation, during each generation.
And our editing will usually be insignificant in the context of the whole human genome. For medical purposes, we will change some rare DNA variations that cause disease into the much more common DNA variations that do not cause disease. Rare, nasty variants will become rarer, but civilization changes these frequencies all the time. For instance, the use of insulin has increased the number of people with DNA variations that predispose people to type 1 ("juvenile") diabetes – because now those people live long enough to reproduce. Even agriculture changed our DNA, leading, for example, to more copies of starch-digesting genes. And, in any event, what is the meaningful difference between "fixing" a disease gene in an embryo or waiting to fix it with gene therapy in a born baby . . . other than avoiding the need to repeat the gene therapy in the next generation?
If genetic enhancement ever becomes possible in a non-trivial way, it would raise important questions, but questions about enhancement generally and not fundamentally about genetics. Enhancement through drugs, prosthetics, brain-computer interfaces, genes, or tools (like the laptop I wrote this on) all raise similar ethical issues. We can use the decades we will have to try to think more systematically about the ethical and policy issues for all enhancements. We should not panic about germline genetic enhancement.
One superficially appealing argument is that we are not wise enough to change our own genomes. This ignores the fact that we have been changing our genomes, inadvertently, since at least the dawn of civilization. We do not have to be wise enough to change our genome perfectly; we just need to be wise enough to change it better than the random and unforeseen ways we change it now. That should not be beyond our power.
Human germline editing will not be a concern for several decades and it may never be an important concern. What should we be paying attention to?
Non-human genome editing. Governments, researchers, and even do-it-yourself hobbyists can use CRISPR, especially when coupled with a technique called "gene drive," 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. We care much less about mosquito babies than human ones and our legal structures are not built for wise and nuanced regulation of this kind of genome editing. Those issues demand our urgent attention – if we can tear ourselves away from dramatic but less important visions of "designer babies."

Disability advocates see remote work as a silver lining of the pandemic, a win-win for adults with disabilities and the business world alike.
Any corporate leader would jump at the opportunity to increase their talent pool of potential employees by 15 percent, with all these new hires belonging to an underrepresented minority. That’s especially true given tight labor markets and CEO desires to increase headcount. Yet, too few leaders realize that people with disabilities are the largest minority group in this country, numbering 50 million.
Some executives may dread the extra investments in accommodating people’s disabilities. Yet, providing full-time remote work could suffice, according to a new study by the Economic Innovation Group think tank. The authors found that the employment rate for people with disabilities did not simply reach the pre-pandemic level by mid-2022, but far surpassed it, to the highest rate in over a decade. “Remote work and a strong labor market are helping [individuals with disabilities] find work,” said Adam Ozemik, who led the research and is chief economist at the Economic Innovation Group.
Disability advocates see this development as a silver lining of the pandemic, a win-win for adults with disabilities and the business world alike. For decades before the pandemic, employers had refused requests from workers with disabilities to work remotely, according to Thomas Foley, executive director of the National Disability Institute. During the pandemic, "we all realized that...many of us could work remotely,” Foley says. “[T]hat was disproportionately positive for people with disabilities."
Charles-Edouard Catherine, director of corporate and government relations for the National Organization on Disability, said that remote-work options had been advocated for many years to accommodate disabilities. “It’s a little frustrating that for decades corporate America was saying it’s too complicated, we’ll lose productivity, and now suddenly it’s like, sure, let’s do it.”
The pandemic opened doors for people with disabilities
Early in the pandemic, employment rates dropped for everyone, including people with disabilities, according to Ozemik’s research. However, these rates recovered quickly. In the second quarter of 2022, people with disabilities aged 25 to 54, the prime working age, are 3.5 percent more likely to be employed, compared to before the pandemic.
What about people without disabilites? They are still 1.1 percent less likely to be employed.
These numbers suggest that remote work has enabled a substantial number of people with disabilities to find and retain employment.
“We have a last-in, first-out labor market, and [people with disabilities] are often among the last in and the first out,” Olzemik says. However, this dynamic has changed, with adults with disabilities seeing employment rates recover much faster. Now, the question is whether the new trend will endure, Olzemik adds. “And my conclusion is that not only is it a permanent thing, but it’s going to improve.”
Gene Boes, president and chief executive of the Northwest Center, a Seattle organization that helps people with disabilities become more independent, confirms this finding. “The new world we live in has opened the door a little bit more…because there’s just more demand for labor.”
Long COVID disabilities put a premium on remote work
Remote work can help mitigate the impact of long COVID. The U.S. Centers for Disease Control and Prevention reports that about 19 percent of those who had COVID developed long COVID. Recent Census Bureau data indicates that 16 million working age Americans suffer from it, with economic costs estimated at $3.7 trillion.
Certainly, many of these so-called long-haulers experience relatively mild symptoms - such as loss of smell - which, while troublesome, are not disabling. But other symptoms are serious enough to be disabilities.
Many had to drop out of the labor force due to long COVID. Yet, about 900,000 people who are newly disabled have managed to continue working. Without remote work, they might have lost these jobs.
According to a recent study from the Federal Reserve Bank of Minneapolis, about a quarter of those with long COVID changed their employment status or working hours. That means long COVID was serious enough to interfere with work for 4 million people. For many, the issue was serious enough to qualify them as disabled.
Indeed, the Federal Reserve Bank of New York found in a just-released study that the number of individuals with disabilities in the U.S. grew by 1.7 million. That growth stemmed mainly from long COVID conditions such as fatigue and brain fog, meaning difficulties with concentration or memory, with 1.3 million people reporting an increase in brain fog since mid-2020.
Many had to drop out of the labor force due to long COVID. Yet, about 900,000 people who are newly disabled have managed to continue working. Without remote work, they might have lost these jobs.
For example, a software engineer at one of my client companies has struggled with brain fog related to long COVID. With remote work, this employee can work during the hours when she feels most mentally alert and focused, even if that means short bursts of productivity throughout the day. With flexible scheduling, she can take rests, meditate, or engage in activities that help her regain focus and energy. Without the need to commute to the office, she can save energy and time and reduce stress, which is crucial when dealing with brain fog.
In fact, the author of the Federal Reserve Bank of New York study notes that long COVID can be considered a disability under the Americans with Disability Act, depending on the specifics of the condition. That means the law can require private employers with fifteen or more staff, as well as government agencies, to make reasonable accommodations for those with long COVID. Richard Deitz, the author of this study, writes in the paper that “telework and flexible scheduling are two accommodations that can be particularly beneficial for workers dealing with fatigue and brain fog.”
The current drive to return to the office, led by many C-suite executives, may need to be reconsidered in light of legal and HR considerations. Arlene S. Kanter, director of the disability law and policy program at the Syracuse University College of Law, said that the question should depend on whether people with disabilities can perform their work well at home, as they did during Covid outbreaks. “[T]hen people with disabilities, as a matter of accommodation, shouldn’t be denied that right,” Kanter said.
Diversity benefits
But companies shouldn’t need to worry about legal regulations. It simply makes dollars and sense to expand their talent pool by 15% of an underrepresented minority. After all, extensive research shows that improving diversity boosts both decision-making and financial performance.
Companies that are offering more flexible work options have already gained significant benefits in terms of diverse hires. In its efforts to adapt to the post-pandemic environment, Meta, the owner of Facebook and Instagram, decided to offer permanent fully remote work options to its entire workforce. And according to Meta chief diversity officer Maxine Williams, the candidates who accepted job offers for remote positions were “substantially more likely” to come from diverse communities: people with disabilities, Black, Hispanic, Alaskan Native, Native American, veterans, and women. The numbers bear out these claims: people with disabilities increased from 4.7 to 6.2 percent of Meta’s employees.
Unfortunately, many leaders fail to see the benefits of remote work for underrepresented groups, such as those with disabilities. Some even say the opposite is true, with JP Morgan CEO Jamie Dimon claiming that returning to the office will aid diversity.
Having consulted for 21 companies to help them transition to hybrid work arrangements, I can confirm that Meta’s numbers aren’t a fluke. The more my clients proved willing to offer remote work, the more staff with disabilities they recruited - and retained. That includes employees with mobility challenges. But it also includes employees with less visible disabilities, such as people with long COVID and immunocompromised people who feel reluctant to put themselves at risk of getting COVID by coming into the office.
Unfortunately, many leaders fail to see the benefits of remote work for underrepresented groups, such as those with disabilities. Some even say the opposite is true, with JP Morgan CEO Jamie Dimon claiming that returning to the office will aid diversity.
What explains this poor executive decision making? Part of the answer comes from a mental blindspot called the in-group bias. Our minds tend to favor and pay attention to the concerns of those in the group of people who seem to look and think like us. Dimon and other executives without disabilities don’t perceive people with disabilities to be part of their in-group. They thus are blind to the concerns of those with disabilities, which leads to misperceptions such as Dimon’s that returning to the office will aid diversity.
In-group bias is one of many dangerous judgment errors known as cognitive biases. They impact decision making in all life areas, ranging from the future of work to relationships.
Another relevant cognitive bias is the empathy gap. This term refers to our difficulty empathizing with those outside of our in-group. The lack of empathy combines with the blindness from the in-group bias, causing executives to ignore the feelings of employees with disabilities and prospective hires.
Omission bias also plays a role. This dangerous judgment error causes us to perceive failure to act as less problematic than acting. Consequently, executives perceive a failure to support the needs of those with disabilities as a minor matter.
Conclusion
The failure to empower people with disabilities through remote work options will prove costly to the bottom lines of companies. Not only are limiting their talent pool by 15 percent, they’re harming their ability to recruit and retain diverse candidates. And as their lawyers and HR departments will tell them, by violating the ADA, they are putting themselves in legal jeopardy.
By contrast, companies like Meta - and my clients - that offer remote work opportunities are seizing a competitive advantage by recruiting these underrepresented candidates. They’re lowering costs of labor while increasing diversity. The future belongs to the savvy companies that offer the flexibility that people with disabilities need.
