A new study reveals how the brain’s reward system may be hijacked by social media algorithms, reinforcing compulsive scrolling behavior through variable reinforcement schedules. Researchers found that unpredictable rewards—such as likes or notifications—trigger dopamine releases similar to those linked to gambling, suggesting a neurological basis for addictive app use. The findings highlight how design choices in digital platforms could inadvertently exploit natural brain mechanisms. Experts warn that understanding these patterns may be key to developing healthier online habits.
