"Fact-checking journalism has become a common practice to counteract misinformation. This research analyzes the perceptions of fact-checkers in Ibero-America on the purposes, principles, and challenges of fact-checking. Specifically, we studied if there are differences in perception based on adherence to the International Fact-Checking Network’s (IFCN) Code of Principles, how frequently fact-checkers perform factchecks, as well as their experience and age. Data were collected through a questionnaire that received 122 responses from factcheckers in 17 countries. Results indicate that journalists’ experience appears to be a variable that can help understand the boundaries between fact-checking and political and social activism in Ibero-America. Less-experienced fact-checkers were more likely to consider activism to be a purpose of fact-checking. Age was a predictive factor for explaining reformist perceptions of the essence of fact-checking in Ibero-America, with younger fact-checkers more likely to state that the purpose of fact-checking is to uphold the ideals of journalism and serve as a commitment to information transparency. Pledging to adhere to IFCN’s Code of Principles was found to facilitate the use and analysis of fact-checking tools. The implications of these findings are discussed." (Abstract)
