The Smartphone Theory of Everything: Are Phones Really to Blame for Anxiety, Populism, and Polarization?

Smartphones get blamed for everything — anxiety, populism, polarization, ADHD, declining marriage rates, the collapse of attention spans. But a comprehensive new investigation by Derek Thompson asks the uncomfortable question: how much of this is actually backed by evidence?

The Smartphone Theory of Everything

NYU professor Arpit Gupta coined the term "Smartphone Theory of Everything" (SToE) — the idea that an unholy nexus of smartphones, the Internet, and social media is uniquely to blame for practically every modern malady. Thompson spent years reporting on this space and analyzed randomized trials, meta-analyses, and a consensus survey of hundreds of academics to separate the strongest claims from the weakest.

The Anglosphere Problem

Here's the most inconvenient fact for smartphone doomers: phones are global, but the worst effects are concentrated in the richest English-speaking countries — the US, UK, Canada, Australia, and New Zealand.

Youth happiness has plummeted in the Anglosphere, but it's risen sharply in Central and Eastern Europe and East Asia. Suicide attempts among young women soared across English-speaking countries, but fell in most European nations. US polarization started in the 1990s with Fox News — two decades before smartphones took off.

Phones as "Attention Alcohol"

Thompson argues smartphones are best understood as "attention alcohol" — fun if moderately problematic for most, and very dangerous for some. Instagram's own research found it made body image issues worse for one-third of teenage girls, but had small or negligible effects on the majority.

The biggest problem isn't what's on the phone — it's what's not on the phone. When researchers removed internet access from smartphones, 90% of participants experienced at least one benefit. They slept more, socialized more, went outside more.

It's the News, Not Just the Phone

Researchers used AI to trace positive vs. negative language across tens of millions of newspaper articles from the 1850s to the 2020s. News positivity was stable for over a century, then negativity surged after the 1960s. Phones didn't make the news more depressing — they just made depressing news easier to access.

The Bottom Line

The smartphone theory of everything is neither completely right nor completely wrong. Compulsive phone use combined with under-regulated social media reliably produces anxiety, attention issues, and polarization — but mainly in highly individualistic societies with negative news ecosystems and expanding diagnostic guidelines. America was simply the first and most dramatic example of all these ingredients coming together. The answer isn't to pretend phones are harmless, but to stop treating them as the single explanation for everything that's gone wrong.
