报告1：Thespread of true and falsenews online

We investigated thedifferential diffusion of all of the verified true and false newsstoriesdistributed on Twitter from 2006 to 2017.The data comprise 126,000stories tweeted by3 million people more than 4.5 million times.We classifiednews as true or false usinginformation from six independent fact-checkingorganizations that exhibited 95 to 98%agreement on the classifications.Falsehood diffused significantly farther, faster, deeper, andmore broadly thanthe truth in all categories of information, and the effects were morepronouncedfor false political news than for false news about terrorism, naturaldisasters,science, urban legends, or financial information.We found that falsenews was more novel thantrue news, which suggeststhatpeople were more likely to share novel information.Whereasfalse storiesinspired fear, disgust, and surprise in replies, true stories inspiredanticipation,sadness, joy, and trust. Contrary to conventional wisdom, robotsaccelerated the spreadof true and false news at the same rate, implying thatfalse news spreads more than the truthbecause humans, not robots, are morelikely to spread it.

This article explores the relevance between We Mediatransmission and online opinions of public events, and analyzes the dilemma ofgovernment's response from the perspectives of We Media transmissioncharacteristics and current situation of government's response. The resultsshow that there exist many problems, such as lacking early-warning techniques,responding in a passive, fragmented,slow and tactless way, influence of man-runmanagement sense, incomplete response system and weak responsibilityconsciousness. Tosolve the dilemma, the government should improve thetechniques of early warning mechanism, establish joint-action mechanism,regularize government's discourse, develop accountability system and form along-term mechanism with institutionalization, standardization, sequencing andsystematization.
