2 September 2026
The World Health Organization's Commission on Social Connection attributed 871,000 annual deaths to loneliness. The figure is real, but it is a modeled estimate built on odds ratios from a literature the Commission itself says is thin outside high-income countries.
8 July 2026
A twelve-month panel study finds chatbot companionship predicts rising loneliness; a broader review of the same literature calls the evidence mixed. The disagreement is about design, not just data.
8 July 2026
Buffet, Timeleft, 222, Pie and Meetup are increasingly described as responses to the loneliness epidemic. No trial has measured whether any of them changes a loneliness score. What the evidence base would need to look like before that claim is available.
20 April 2026
A close look at how the American Psychological Association's 2026 review of AI companionship hedged its conclusions, and whether the hedge holds up against a longitudinal study published two months later.
5 April 2026
A new longitudinal study finds chatbot use predicts later loneliness, and loneliness predicts later chatbot use. The finding is more precise than most coverage of AI companionship allows, and policy has not yet absorbed it.
31 March 2026
A study in Science this year ties remote work to rising isolation and mental distress. The proposed mechanism runs from time alone to loneliness to worse outcomes, and the evidence for each link is uneven.
17 March 2026
Self-report loneliness surveys disagree by tens of percentage points depending on instrument and year. Time-use diaries and health-system administrative data tell a steadier, less noisy story about actual isolation.
6 February 2026
Governments are writing technology-specific loneliness policy on the back of evidence that mostly cannot distinguish correlation from cause, or isolation from loneliness. That gap has consequences for what gets funded.
20 December 2025
A new nationally representative study tests the popular claim that remote work drives loneliness. The literature on this question has almost no null results, which is itself worth examining.
15 December 2025
A review of what published research establishes about the economic cost of loneliness and social isolation, and why almost none of the widely cited figures come from a genuine cost-effectiveness study.
19 October 2025
A methods-level look at how the WHO Commission on Social Connection handled the uncertainty behind its headline mortality estimate, and how carefully it treated technology's contested role as a cause rather than a correlate of loneliness.
17 September 2025
Self-reported loneliness has risen sharply across a decade of surveys, but the American Time Use Survey's diary method shows a slower, longer decline in face-to-face contact. The two measures are not tracking the same thing.
17 August 2025
The Commission on Social Connection's June 2025 report links loneliness to an estimated 871,000 deaths a year. An assessment of what that figure rests on, how the report hedged it, and why the technology question was the hardest part for it to hold.
15 May 2025
Most evidence tying adolescent social media use to loneliness is cross-sectional. A look at what the small number of longitudinal studies show, and what they still cannot resolve.
11 April 2025
A look at what the loneliness literature actually says about economic cost and cost-effectiveness, and why the figures most often quoted are not what they appear to be.
16 January 2025
Health systems are being told to screen routinely for social isolation and loneliness, often through digital intake tools. The evidence for the screening instrument is solid. The evidence that screening improves outcomes is not.
31 December 2024
The AHA's 2022 scientific statement on social isolation and cardiovascular health is unusually explicit about the limits of its own evidence base. That candor is worth examining on its own terms.
29 November 2024
National loneliness measurement rests on instruments that were designed to ignore how contact happens. That design choice is defensible for validity and disabling for technology policy.
31 October 2024
Across national and global surveys, adults under 30 consistently report the highest loneliness rates. The evidence for why is thinner than the finding itself.
21 October 2024
Jonathan Haidt's claim that the shift to phone-based childhood caused rising adolescent loneliness is a specific, falsifiable mechanism. The correlational data available so far cannot adjudicate it.
10 September 2024
Most evidence linking technology use to loneliness comes from single-timepoint surveys. That design cannot distinguish cause from effect, and the one Japanese study built to do so shows why that gap matters.
7 July 2024
The comparison between loneliness and smoking traces back to a single meta-analysis's effect-size comparison. Tracking its path through the Surgeon General's advisory and into federal surveillance shows how much nuance the number lost along the way.
30 June 2024
School and legislative proposals to restrict adolescent smartphone use are increasingly justified as remedies for youth loneliness. The intervention evidence for that specific claim does not yet exist.
1 April 2024
The World Health Organization's new Commission on Social Connection leans on a Gallup-Meta survey covering 142 countries. Its sampling frame has gaps that matter for exactly the populations policy is meant to reach.
2 January 2024
A widely cited claim that 72% of people worldwide feel socially connected comes from a single self-report item in a Meta-funded Gallup survey. What it measured, and what policy bodies are doing with it, are not the same thing.
20 December 2023
The Surgeon General's National Strategy calls for reforming digital environments to reduce loneliness. The evidence base for that pillar is thinner than for any other part of the strategy, and the gap matters for what regulators can credibly do next.
17 September 2023
A specific clinical recommendation -- screen older patients for isolation, then refer them to technology-mediated connection -- rests on strong mortality data and almost no intervention evidence.
6 June 2023
Five major reviews since 2020 have converged on the same finding: governments are building loneliness policy on strong association evidence and almost no intervention evidence, technology-based approaches included.
9 April 2023
Surveys tracking loneliness alongside rising smartphone and social media use rarely measure technology use with enough precision to support the causal claims often drawn from them.
28 January 2023
Holt-Lunstad's 2010 finding that weak social ties carry a mortality risk comparable to established health hazards has travelled from meta-analysis to national strategy. The evidence for what to do about it has not kept pace.
23 November 2022
The literature on connection interventions and connection tools almost never reports a failure. An examination of why, and of what a genuine null result would have to look like to be recognised as one.
8 September 2022
The American Heart Association's August 2022 scientific statement split social isolation into objective and perceived components. The revision clarifies cardiovascular risk research but leaves unresolved whether contact by phone or video counts.
1 May 2022
A comparison of the major loneliness surveys of the past four years shows sharply different prevalence figures and almost no way to tell which populations, mechanisms, or interventions actually move them.
28 March 2022
Cigna's widely cited 2020 finding that 61% of U.S. adults are lonely has shaped policy talk about remote work and Gen Z. The instrument behind it differs from the academic standard in ways that matter.
25 October 2021
The Making Caring Common report attributes rising loneliness to the pandemic and, implicitly, to the poor quality of technology-mediated contact. Its own data support a narrower claim than its title suggests.
16 August 2021
The most widely used loneliness instrument was designed in the late 1970s around assumptions about contact that digital communication has scrambled. A look at what it measures, and what it cannot.
13 February 2021
The National Academies has recommended that health systems routinely screen for social isolation and loneliness. The evidence behind identifying the problem is far stronger than the evidence behind what to do once it is found.
