Other way around. A lot of things are rotting our brains, and doom scrolling is one of the results. There's a positive feedback loop, probably, but we were rotting our brains long before doomscrolling.<p>Neil Postman's 1985 book "Amusing Ourselves To Death" describes a similar phenomenon with TV and radio. And that was before cable news brought us "doom-viewing" with the first Iraq War and 9/11, where people felt compelled to tune in continuously for updates. Even between crises, people watch news for enjoyment, usually to be told about all the terrible things happening.
