6 Times Faster
MIT researchers studied 126,000 contested news stories shared by 3 million people more than 4.5 million times on Twitter between 2006 and 2017. It is the largest longitudinal study of false news ever conducted.
The finding was unambiguous. False news reached its first 1,500 people six times faster than true news. Falsehoods were 70% more likely to be retweeted. False news spread “farther, faster, deeper and more broadly than the truth in every category of information.”
6x faster. 70% more likely to be shared. False news outperformed the truth in every category MIT measured.
The researchers expected bots to be the primary driver. They were not. Humans spread false news more than bots. False stories were more novel, and people are more likely to share novel information. The algorithms amplified what people already wanted to share.
Why This Matters for Everything Else
Every policy fight on this site operates in an information environment where false claims have a structural advantage. When the administration claims noncitizen voting is a crisis (it is 0.0003% of ballots), the false claim travels faster than the correction. When RFK Jr. promotes debunked vaccine claims, the claims reach more people than the peer-reviewed evidence.
The anti-trans funding trail spent $215 million on TV ads. Those ads do not need to be true to be effective. In an environment where false news spreads 6 times faster, the volume of a claim matters more than its accuracy.
The Platform Design
Social media platforms optimize for engagement. Content that provokes outrage, fear, or surprise generates more clicks, shares, and time on site. False news is more novel and more emotionally provocative than true news. The algorithm does not distinguish between them. It promotes what gets engagement.
This is not a flaw. It is the business model. The platforms generate revenue from attention. False news generates more attention. The economic incentive and the misinformation incentive point in the same direction.
The Local Connection
When 2,900 newspapers closed and 212 counties became news deserts, the information vacuum was filled by social media. 51% of news desert residents get local news from non-journalistic sources. The combination of fewer professional reporters and an algorithm that rewards false claims creates the conditions for misinformation to become policy.
Press freedom at 64th measures the political conditions. The algorithm measures the structural conditions. Both move in the same direction. Less professional journalism. More algorithmic amplification of unverified claims. The information environment that democracy depends on is deteriorating from both sides.
