Countering False Information on Social Media in Disasters and Emergencies: Social Media Working Group for Emergency Services and Disaster Management [open pdf - 1MB]
"This white paper examines motivations people may have for sharing false information, discusses underlying issues that cause false information and offers case studies from recent disasters to illustrate the problem. Multiple motives lead people to post false information on social media: some posters seek a particular result, such as closing schools for the day; some desire to get attention with a dramatic post; some are pushing a money-making scam or political agenda; and some innocently repeat bad or outdated information. Best practices for agencies to counter misinformation, rumors and false information are detailed and categorized in this white paper, and challenges and additional considerations are presented for review. This report illustrates methods of countering false information on social media with case studies: the 2014 South Napa earthquake: tweets were filtered by geolocation to eliminate posts from trolls; the 2016 Louisiana floods: the Red Cross published and shared a blog to counter rumors and misinformation about food distribution and shelter policies; the 2017 Oroville Dam evacuation: an accidentally misleading tweet suggested the evacuation area included all of Sacramento County. Local agencies used traditional and social media to provide correct information."
