In this era of rampant misinformation, the role of fact-checkers is becoming increasingly important. Yet, the practice is relatively understudied. Research from the University of Kansas has analyzed how fact-checkers in four countries practice the craft in relation to the contentious issue of climate change. In addition to finding that fact-checkers across the world have different approaches, the researchers suggest the most effective ways to approach the practice to provide accurate, reliable and easy to understand information to the public.
