Social feedback mechanisms & misinformation: A neuroscience-based argument for algorithm regulation

Psychological and neuroscience research reveals how motivational systems in the brain interact with the structure of social media platforms to enhance the propagation of misinformation. Features such as likes activate the brain’s reward system, encouraging people to share more emotionally engaging content, especially that which provokes outrage against opposing groups. False information is more likely to evoke outrage than is truthful information. Furthermore, exposure to misinformation increases its perceived credibility, and later corrections often fail to override its influence. To reduce impacts of false information, regulation of social media platforms should focus partly on the algorithms that prioritize content. Additionally, investing in media literacy interventions and grassroots efforts can bolster people’s motivation and ability to resist misleading content.
