"Despite earlier scientific theories, dopamine doesn't give us pleasure. Since the 1990s, neuroscientists have accumulated evidence debunking this idea. Instead, dopamine makes us want. Rosy didn't love her videos, Doucleff realized. Nor did she love the ultraprocessed Ritz crackers she begged for at the grocery store. Rosy was caught in a wanting feedback loop. The more she watched and ate snack foods, the more she wanted to watch and eat."
"There's a separate, second system in our brain that makes us like what we're wanting and feel satisfied when we get it. Modern technology splits the systems apart, so we're left always wanting more, even when whatever we're doing—whether it's scrolling TikTok or eating potato chips—doesn't bring us much, or any, pleasure."
Michaeleen Doucleff, a biochemist and science journalist, discovered that outdated parenting advice failed to address her daughter's intense reactions to screen time removal. Through current neuroscience research, she learned that dopamine doesn't produce pleasure but rather creates wanting. Modern technology and ultraprocessed foods exploit this wanting system by separating it from the brain's satisfaction mechanism. This split causes continuous craving without fulfillment—children want more screens and snacks despite minimal actual enjoyment. Understanding this dopamine-driven feedback loop explains why children struggle with screen and food restrictions, revealing that the problem isn't deprivation but rather how technology hijacks the brain's motivational systems.
