The framework scores content on four dimensions mapped to neurochemicals: learning (acetylcholine), engagement (dopamine), breakthrough (norepinephrine), and mood (serotonin/endorphins). It draws on research by Hasselmo, Schultz, and Aston-Jones to balance cognitive benefit rather than maximize engagement.

Traditional platforms use variable reward schedules, infinite scroll, and outrage-driven content that spike dopamine and cortisol. This feed uses finite curated content, transparent scoring, and consistent quality without manipulation patterns.

The model cites Hasselmo (2006) on acetylcholine and memory, Schultz (1997) on dopamine prediction errors, Aston-Jones and Cohen (2005) on norepinephrine, and Young (2007) on serotonin. It also references Twenge et al. (2018) on social media harms.

Yes, the framework is user-controlled. After reviewing the science, you can run the feed-prefs command to adjust weights across learning, engagement, breakthrough, and mood dimensions to match your goals.

The framework is presented as a hypothesis rather than proven outcome, claiming better retention and mood without post-use regret. The neurochemical mappings are simplified models of complex brain chemistry and should be read as design heuristics.
