Hari interviews scientists, tech insiders, and activists to document twelve causes of the attention collapse: the speed of the information environment, sleep deprivation, pollution, childhood play deprivation, ADHD over- and under-diagnosis, and — centrally — the design of social media platforms optimized for engagement above all else.
The book's most useful contribution for DarkBadge's framing: distinguishing between attention (the ability to focus on one thing) and engagement (compulsive checking behavior). Social media platforms are extremely good at generating engagement. They are often catastrophic for attention. These are not the same thing, and conflating them is a design industry failure with real consequences for the humans using the products.
The chapter on the surveillance capitalism business model — citing Shoshana Zuboff — explains why platform incentives cannot be solved by user willpower alone. The platform's revenue depends on maximizing engagement, which means maximizing attention capture at the expense of user wellbeing. No amount of mindful usage changes this structural incentive.
