There
is worldwide concern over false news and the possibility that it can
influence political, economic, and social well-being. Vosoughi et al investigated the differential diffusion of all of the verified true and
false news stories distributed on Twitter from 2006 to 2017. The data
comprise ~126,000 stories tweeted by ~3 million people more than 4.5
million times.

They classified news as true or false using information from six independent fact-checking organizations that exhibited 95 to 98% agreement on the classifications.
False news reached more people than the truth; the top 1% of false news cascades diffused to between 1000 and 100,000 people, whereas the truth rarely diffused to more than 1000 people.
The effects were more pronounced for false political news than for false news about terrorism, natural disasters, science, urban legends, or financial information. They found that false news was more novel than true news, which suggests that people were more likely to share novel information. Whereas false stories inspired fear, disgust, and surprise in replies, true stories inspired anticipation, sadness, joy, and trust.
Contrary to conventional wisdom, robots accelerated the spread of true and false news at the same rate, implying that false news spreads more than the truth because humans, not robots, are more likely to spread it.
