Content¶

CLAIM: Dopamine and serotonin have opposing effects on decision-making, learning, and cognitive processing

CONFIDENCE: ★★★★★ (Established - multiple replications, mainstream neuroscience)

ESTABLISHED MECHANISMS:

DOPAMINE (Accelerator): - Acts as accelerator for reward-seeking behavior - Signals when outcomes exceed expectations - Promotes immediate action and approach behavior

SEROTONIN (Brake): - Functions as brake promoting patience and long-term thinking - Creates inhibitory "wait" signals - Promotes learning from punishments

SOURCES: - Stanford 2024 study (Nature) - Meta-analytic evidence (PMC12159863)

STATUS: ✅ ESTABLISHED
