Modern WisdomIs There A Loneliness Epidemic? - Noreena Hertz | Modern Wisdom Podcast 266
CHAPTERS
- 0:00 – 0:26
Loneliness as a major health risk (worse than you think)
Noreena Hertz opens with the medical stakes of loneliness, framing it as a public-health issue rather than a soft emotional topic. She cites research linking loneliness to major disease risks and worse recovery outcomes.
- •Loneliness compared to smoking 15 cigarettes/day in health impact
- •Higher risk of heart disease, dementia, and stroke
- •Loneliness can reduce recovery odds when already ill
- •Sets urgency: loneliness is not just “in your head”
- 0:26 – 3:33
Why an economist started studying loneliness
Chris asks why an economist is focused on loneliness. Hertz explains the three converging triggers that pushed her into the topic: students’ struggles, political polarization, and personal experience with consumer tech.
- •Students increasingly reporting loneliness and isolation
- •Young people struggling with face-to-face interaction (even needing ‘read a face’ help)
- •Loneliness showing up in interviews with right-wing populist voters as a driver of belonging
- •Buying an Alexa prompted questions about AI companionship and connection
- 3:33 – 4:58
The ‘loneliness economy’ and the craving for shared experiences
Hertz describes a pre-pandemic market response to loneliness: paid and organized experiences that manufacture community. She uses Durkheim’s idea of “collective effervescence” to explain why people seek in-person shared energy.
- •A growing economy built around reducing loneliness or simulating connection
- •Collective effervescence: psychological need for shared in-person moments
- •Examples: clubs, escape rooms, boutique fitness (e.g., SoulCycle)
- •Loneliness as a prism for understanding social and political shifts
- 4:58 – 5:53
Defining loneliness: personal and political disconnection
Asked to define loneliness, Hertz broadens it beyond missing friends and family. She argues loneliness includes feeling uncared for by workplaces and government—making it both personal and political.
- •Loneliness includes disconnection from friends/family and craving closeness
- •Also includes disconnection from employer, institutions, and government
- •Feeling unsupported and uncared for as a driver
- •Drivers include economic, technological, and demographic forces
- 5:53 – 9:43
Measuring loneliness: subjective feeling, real-world prevalence
Chris challenges how loneliness can be measured objectively. Hertz agrees measurement is messy but argues the scale of the problem is clear in survey data, especially pre-pandemic and amplified during COVID.
- •Loneliness measurement parallels challenges in measuring pain and emotions
- •Pre-pandemic: 1 in 5 UK adults lonely always/most of the time
- •Half of 18–24-year-olds report regular loneliness
- •Workplace loneliness is widespread (e.g., 60% UK workers feel lonely at work)
- •Pandemic worsened loneliness especially for young people, low-income groups, and women
- 9:43 – 10:59
Why young adults are the loneliest generation
Chris is surprised that 18–24-year-olds are most affected. Hertz explains how you can be lonely in crowds and why youth loneliness is uniquely intense today compared to stereotypes about social university life.
- •Lonely in a crowd vs. not lonely when alone
- •Data: young people are loneliest, not the elderly (contrary to common belief)
- •University proximity doesn’t guarantee connection
- •Youth experience a different social environment shaped by screens
- 10:59 – 15:52
Social media’s role: addiction, exclusion, and visible rejection
Hertz details how social platforms can worsen loneliness for many teenagers by pulling attention away from real-world interactions and amplifying social exclusion. She shares interview stories illustrating the pain of ignored posts, exclusion from plans, and public visibility of rejection.
- •Platforms are designed to be addictive, reducing presence in face-to-face life
- •Quality of in-person relationships declines with constant phone attention
- •Exclusion becomes constant and highly visible (likes, group chats, feeds)
- •Adults/teachers often can’t see the exclusion, reducing chances of intervention
- •Acknowledges exceptions where social media can be a lifeline (e.g., LGBTQ youth)
- 15:52 – 17:41
From correlation to causation: the Stanford ‘delete Facebook’ study
Hertz discusses research that tested whether social media causes loneliness rather than just correlating with it. She describes a Stanford experiment where deleting Facebook led to less internet use overall, more in-person time, and improved well-being.
- •2012–2014 era coincides with sharp rises in loneliness among youth
- •Stanford study: 3,000 students; control vs. delete Facebook for two months
- •Those off Facebook spent less time online overall (not just switching platforms)
- •More in-person socializing, less loneliness, more happiness
- •Claim: deleting Facebook ~40% as beneficial as therapy (per researchers)
- 17:41 – 20:25
Regulation vs. self-control: treating social media like tobacco
Chris and Hertz debate solutions, including bottom-up behavior change and top-down regulation. Hertz argues regulation is essential, likening social media companies to modern tobacco firms, especially regarding child harm.
- •Need for both self-regulation and policy interventions
- •Social media framed as the ‘tobacco companies of the 21st century’
- •UK legislative movement to hold platforms accountable for online harms
- •Concern: difficult balance with freedom of speech and platform liability
- •Practical ‘draconian’ personal strategies: distance phone, change defaults
- 20:25 – 22:08
Has loneliness always existed? Language, history, and hidden isolation
Chris asks when society last didn’t have mass loneliness. Hertz explains that loneliness as a named phenomenon rises in the 1800s, but isolation likely existed earlier without being expressed in the same terms.
- •The concept/word ‘lonely’ entered common vernacular largely from the 1800s
- •Religious frameworks may have shaped whether people described themselves as lonely
- •Many historical conditions could be lonely (abuse, marginalization, poverty)
- •Absence of the term doesn’t mean absence of the experience
- 22:08 – 25:01
What changed: living alone, weaker institutions, and ‘neoliberal’ individualism
Hertz lays out structural drivers of modern loneliness beyond technology. She points to more people living alone, declining community institutions, and a cultural shift toward individualism since the 1980s.
- •More people live alone now than ever; living alone correlates with higher loneliness risk
- •Decline in shared activities and institutions (church, unions, civic participation)
- •‘Neoliberal mindset’ emphasizes self-interest and individual centrality
- •Cultural indicators: pop lyrics shifting from ‘we/us’ to ‘me/I’
- •Trade-offs between individualism and community (freedom and fraternity)
- 25:01 – 28:40
Cities as loneliness machines: speed, scale, and hostile architecture
Hertz argues cities paradoxically produce more loneliness despite density. She explains how pace, reduced civility, car-centric planning, and ‘hostile architecture’ discourage lingering and casual connection.
- •Cities are reported as the loneliest habitats despite many people nearby
- •Richer cities correlate with faster walking speeds; density can correlate with less civility
- •Car-centric design reduces human-scale interaction
- •Hostile architecture excludes groups and reduces social mixing
- •Examples: anti-teen bathroom lighting, high-frequency deterrent sounds, Camden Bench design
- 28:40 – 37:21
Extreme loneliness stories: paid cuddling and ‘community’ in jail
Chris asks for extreme examples, and Hertz shares two striking cases: a professional cuddling industry in Los Angeles and Japanese elderly committing minor crimes to be incarcerated for companionship. These illustrate the lengths people will go to access touch and community.
- •Professional cuddling as part of the ‘loneliness economy’
- •Case study: Carl pays for cuddling, eventually lives in his car to afford it
- •Group cuddle sessions described as structured, consensual, and ‘normal’ attendees
- •Japan: elderly shoplifting to get jailed for companionship
- •Loneliness as pervasive, with extreme cases highlighting broader patterns
- 37:21 – 40:34
What loneliness does to the body: fight-or-flight and inflammation
Hertz explains the physiological mechanism: loneliness triggers chronic stress responses designed to push humans back toward the group. When sustained, these responses increase inflammation and weaken immunity, contributing to long-term disease risk.
- •Humans are ‘hardwired to connect’; loneliness triggers alarm systems
- •Increases in blood pressure, heart rate, and cortisol
- •Chronic fight-or-flight harms the body over time (engine-in-first-gear analogy)
- •Sustained stress dampens immune response and raises inflammation
- •Mechanistic link to higher risks of heart disease, dementia, stroke
- 40:34 – 42:46
Lasting damage—and repair: short loneliness spells still matter
Chris wonders whether loneliness effects are reversible if life improves later. Hertz cites evidence that even under two years of loneliness can reduce life expectancy, but emphasizes that reconnection and helping others can restore health trajectories.
- •Research suggests even short loneliness periods can significantly impact life expectancy
- •Good news: connection and community participation improve longevity
- •Helping others boosts health and lifespan (and reduces loneliness)
- •Importance of investing in relationships as an active practice
- 42:46 – 45:41
Partners vs. friendships: what actually protects against loneliness
Chris proposes marriage and family as a solution, but Hertz cautions that relationships can coexist with loneliness or even worsen it. They converge on the value of high-quality relationships and strong friendships as durable support structures.
- •Being in a relationship doesn’t automatically prevent loneliness
- •Pandemic-linked rise in domestic abuse highlights risks, especially for women
- •Focus on relationship quality, not just relationship status
- •Friendships can be powerful, stable, and deeply supportive
- •Divorce rates suggest many partnerships aren’t protective in practice
- 45:41 – 54:50
Remote work, office design, and the value of ‘micro-exchanges’
They explore how remote working and certain office layouts affect connection and workplace loneliness. Hertz and Chris highlight the underestimated importance of small, routine interactions and cite evidence that many workers choose to return to offices even after remote trials.
- •Remote work ‘euphoria’ wears off; many (especially young) want office return
- •Lonely workers hurt business: lower productivity and higher quit rates (60% more likely)
- •Open-plan offices can paradoxically increase loneliness and reduce openness
- •Pandemic revealed the importance of small social moments (café chats, colleagues)
- •China experiment: many employees chose office return despite long commutes
- 54:50 – 58:31
Post-pandemic social rebound: why connection will surge again
Chris worries about long-term social damage and collapsed nightlife/leisure infrastructure. Hertz is optimistic, pointing to historical rebounds (post-1918 flu) and recent examples in places that reopened, predicting a ‘social roaring’ driven by pent-up need.
- •Historical precedent: roaring 1920s followed the 1918 Spanish flu
- •Examples of rapid return to gatherings: Taipei shows, festivals in Australia/NZ, Israel yoga demand
- •Humans’ desire for togetherness is resilient and likely to prevail
- •Chris notes constraints: venue closures and industry collapse reduce capacity
- •Hertz predicts new community-focused ventures will emerge from the ashes
- 58:31 – 1:00:55
Practical anti-loneliness prescriptions: hobbies, groups, and helping others
Hertz offers concrete steps for individuals who feel lonely: join interest-based communities and volunteer or help others. She emphasizes that contribution creates connection and that the ‘helper’s high’ makes prosocial behavior self-reinforcing.
- •Find a shared activity community (improv, singing, chess, etc.)
- •Use Zoom as a bridge when in-person isn’t possible
- •Helping others reduces loneliness and increases connection
- •‘Helper’s high’: dopamine/positive physiological response from giving
- •Connection comes from participation, not just passive social contact
- 1:00:55 – 1:02:04
