SCIENCE

The Claim

The majority of online misinformation is spread by human users rather than automated bots.

The Short Version

The weight of available research supports the claim that human users remain the primary drivers of online misinformation spread, though the picture is more nuanced than the claim suggests. The most rigorous large-scale studies show that false news diffusion patterns persist even after removing bot accounts, and human behavioral mechanisms — habitual sharing, platform incentives, superspreaders — remain dominant factors. However, bots punch well above their weight in specific contexts, and the rapid rise of AI-generated content since 2023 is narrowing the gap in ways not yet fully measured.

Caveats

  • Key supporting studies (MIT 2018, Internet Society 2018) predate the large language model era; AI-generated misinformation is scaling rapidly and may be shifting the human-bot balance in ways current research has not fully captured.
  • Bots representing less than 1–6% of users can account for 30%+ of misinformation content in specific political contexts, meaning the human 'majority' is smaller than it appears when measured by impact rather than user count.
  • The claim does not distinguish between misinformation creation and diffusion — bots may play a larger role in origination and amplification than in person-to-person sharing, and during crises bot-driven misinformation approaches parity with human-driven content.
