Slow down. You're not a rat.
Extension Metadata
About this extension
Infinite feeds aren't neutral. They're engineered to hijack your brain's dopamine system. Every refresh is an unpredictable, variable reward, the most addictive reinforcement pattern there is.
In 1954, neuroscientists Olds and Milner let rats press a lever to electrically stimulate the reward center of their own brains. The rats pressed it compulsively, ignoring food, water, and sleep until they collapsed. Modern feeds run the same loop on us: scroll, hit, scroll, hit, chasing the next hit that may or may not come.
Not a Rat is a gentle interruption to this pattern. When it notices you doomscrolling or frantically clicking, it pops up a reminder to slow down, you're not a rat. Few seconds to take a deep breath and be mindful. No accounts, no tracking, nothing leaves your browser.
Browse on purpose. Don't just press the lever.
