Book description

This [handbook] provides an overview of the process by which The Debunking Handbook 2020 was created during May – October 2020. The new Handbook replaces the first Debunking Handbook (http://sks.to/debunk), published in 2011 by John Cook and Stephan Lewandowsky. The scientific knowledge about debunking has shifted considerably during the decade since publication of the first Handbook. (The evolution of the scientific evidence was already reflectedin an update notice of the first Handbook published in June 2017 at https://www.skepticalscience.com/Debunking-Handbook-now-freely-available-download.html#UpdateJune2017 ). In addition to updating the science of debunking, The Debunking Handbook 2020 also sought to represent the scientific consensus on debunking as of 2020. It was therefore developed using a preregistered approach that was, in part, inspired by research on the process of consensus formation in a medical/clinical context (e.g., Rosenfeld, Nnacheta, & Corrigan, 2015). Our approach was also informed by precedents in psychology, for example, the development and report of an expert consensus for the psychology of eyewitness testimony (Kassin, Tubb, Hosch, & Memon, 2001). Our approach departed from precedents by preregistering our methodology and intended completion schedule.
