COVID-19 and America's response to it are likely to profoundly affect our families, work lives, relationships and gender roles for years, say 12 prominent scientists and authors who analyzed 90 research studies and used their expertise to evaluate our reaction to the pandemic and predict its aftermath.
The group, which included several UCLA researchers, foresees enduring psychological fallout from the crisis, even among those who haven't been infected. Their predictions and insights, published Oct. 22 in the journal Proceedings of the National Academy of Sciences, include:
"The psychological, social and societal consequences of COVID-19 will be very long-lasting," Haselton said. "The longer COVID-19 continues, the more entrenched these changes are likely to be."
COVID-19: A worldwide social experiment
As marriage rates plummet and people postpone reproduction in a virus-plagued world, some nations' populations will shrink and fall precipitously below "replacement level," the authors write. These birthrate drops, in turn, can have cascading social and economic consequences, affecting job opportunities, straining the ability of countries to provide a safety net for their aging populations and potentially leading to global economic contraction.
Research has shown that ever before the pandemic, women were more stressed than men by family and job responsibilities. Now they are managing more household responsibilities related to child care and education. In medicine and other sciences, women scholars are already publishing substantially less research than they did a year ago, while men are showing increased productivity, Haselton said.
She and her co-authors foresee a shift toward social conservatism. A consequence of the pandemic could be less tolerance for legal abortion and the rights for sexual minorities who don't align with traditional gender roles. In addition, in a time of economic inequality, many women will sexualize themselves more to compete with one another for desirable men, Haselton said.
People who meet online will often be disappointed when they meet in person. "Does a couple have chemistry? You can't tell that over Zoom," Haselton said. In new relationships, people will miss cues, especially online, and the disappointing result will often be overidealization of a potential partner — seeing the person the way you want the person to be rather than the way the person actually is.
The pandemic has become a worldwide social experiment, say the authors, whose areas of expertise include psychology, neuroscience, behavioral science, evolutionary biology, medicine, evolutionary social science and economics.
An evolutionary struggle
For the study, the authors used an evolutionary perspective to highlight the strategies the virus has evolved to use against us, the strategies we possess to combat it and the strategies we need to acquire.
Humans today are the products of social and genetic evolution in environments that look very little like our current world. These "evolutionary mismatches" are likely responsible for our frequent lack of alarm in response to the pandemic, the scientists write.
Americans in particular value individuality and the ability to challenge authority. "This combination does not work especially well in a pandemic," Seitz said. "This virus is exposing us and our weaknesses."
Haselton agreed, calling the virus "wily" for its ability to infect us through contact with people we love who seem to be healthy. "Our social features that define much of what it is to be human make us a prime target for viral exploitation," she said. "Policies asking us to isolate and distance profoundly affect our families, work lives, relationships and gender roles."
All infectious agents, including viruses, are under evolutionary pressure to manipulate the physiology and behavior of their hosts — in this case, us — in ways that enhance their survival and transmission. SARS-CoV-2, which causes COVID-19, may be altering human neural tissue to change our behavior, the authors say. It may be suppressing feelings of sickness, and perhaps even enhancing our social impulses, during times of peak transmissibility before symptoms appear. People who are infected but do not feel sick are more likely to go about their usual activities and come in contact with others whom they might infect.
Disgust is useful and motivates us to avoid people who display clear signs of disease — such as blood, pale skin, lesions, yellow eyes or a runny nose. But with COVID-19 infections, this is not what most people see. Family, friends, co-workers and strangers can look perfectly healthy and be asymptomatic for days without knowing they are infected, the authors note.
It may sound counterintuitive, but normal brain development requires exposure to a diverse set of microbes to help prepare younger animals for a range of pathogenic dangers they may encounter in adulthood. But safer-at-home and quarantine health measures have temporarily halted social activities that would otherwise bring millions of adolescents into contact with new microbes. As a result, children and adolescents whose immune systems and brains would, in normal times, be actively shaped by microbial exposures may be adversely impacted by this change, the scientists say.
By understanding how SARS-CoV-2 is evolving and having behavioral and psychological effects on us that enhance its transmission, we will be better able to combat it so it becomes less harmful and less lethal, the authors write.
