Summary

A landmark 2018 MIT study analyzing 126,000 Twitter rumor cascades from 2006-2017 found that false news spreads significantly faster, farther, and more broadly than true news—often by an order of magnitude. Crucially, the research determined that humans, not automated bots, are the primary drivers of misinformation spread, suggesting the problem is rooted in human psychology and information-seeking behavior rather than purely technical manipulation.

Key Points

  • False news spreads farther, faster, deeper, and more broadly than true news across all information categories, often by an order of magnitude.
  • Humans—not bots—are primarily responsible for the rapid spread of misinformation on Twitter.
  • The study analyzed ~126,000 rumor cascades on Twitter spanning 2006–2017, making it one of the largest studies of its kind.
  • False stories were 70% more likely to be retweeted than true stories, and reached audiences of 1,000+ users six times faster.
  • The novelty of false information, which tends to be more surprising and emotionally provocative, may explain why humans preferentially share it.
