How did you and Peter Sterling both become interested in examining the effects of despair in the context of population declines?
We’re biologists, and when a biologist notices that species fertility has fallen well below replacement for many years—since 1973 in U.S.—there are two big questions. One, how long will this continue because eventually it leads to population collapse and extinction? And two, since the biological drive to produce offspring is normally so strong but in this case is superseded by a more powerful force, we wondered what is the cause of collapsing fertility.
Given our interest in the causes of rising despair and its accompanying rise in mortality through suicide, alcohol, and drug overdose—plus rises in cardiovascular disease and diabetes caused by foods of despair and lack of social exercise—we hypothesized a connection. Having teenage children, I’m especially tuned in to the roles of social media and screen time in rising despair in young people.
You cite a major economic concern related to a fertility decline, an altered population structure (reduced proportion of youth) leading to vast vacancies in entry-level and more physically demanding roles, but what else are you worried about?
The economic concerns are clear: Who will do all the work?
But there are further concerns, such as how will we care for our aging population, and where will the money come from? And with fewer consumers, who will buy stuff, the grist for the mill of capitalism? And without young, creative people where will moonshot innovations come from to fight existential challenges like climate change? Taken to the extreme, a world without children is a world without hope, as vividly portrayed in the film ‘Children of Men.’
Are there any effective long-term ‘pronatalist’ initiatives that you have seen in action? What are some other causes for these failures?
As noted in the paper, various social subsidies have been tried to ‘kick-start’ fertility, but to the extent they stimulate reproduction, it’s a weak effect and brief at that.
Despair is rising most steeply for those of reproductive age, so it stands to reason that young people who don’t even want to live or who use lethal practices like drugs or greasy foods to elevate their mood are unlikely to find a 20-year commitment to rearing a child appealing.
Do you think young people’s outlook on their economic prospects may be affecting their moods, which may exacerbate some of the declines?
Absolutely! As we note in the paper, for many people today, rewards experienced through both material gains and genuine social interactions are in decline, and these deficits are further exacerbated by comparisons with others on social media. We contend that this negative momentum serves as a potent driver diminishing fertility and increasing deaths of despair.
Do you have any comparative information on how despair or declining birth rates differ between more isolated roles versus team-driven ones?
Not yet, but we do note that recent polls find that more than 25% of remote workers report being lonely. Younger people love working from home, but their lack of opportunities to connect with co-workers in the real world may contribute to rising despair and declining interest—and even opportunities—to find a mate and have children, as argued recently by our colleague Scott Galloway of New York University.
What recommendations do you and Peter Sterling have to remedy this? Also, how do you get people to care?
If falling fertility is indeed caused by rising inequality and social disconnection, the cure would not lie in minor tweaks such as maternal subsidies and more childcare centers. Rather, it would entail thorough socioeconomic restructuring to reduce inequality and restore all aspects of social life that have been so severely degraded. The ‘no cellphones in schools’ movement is one positive step in that direction.
Our species has gone through bottlenecks before. If we provide young people with opportunities for real careers of learning and growth in skills with meaningful jobs, they will perk right up. Reduce their terrible social isolation and they will respond.
