"We conducted a mixed-methods research project in Nigeria, India, and Pakistan consisting of surveys, survey experiments, and semi-structured interviews, to better understand the spread and impact of misinformation, and in particular of misinformation on mobile messaging apps (MIMs). One of our goals was to evaluate the relevance and prevalence of viral false claims in each country. We found evidence that popular “false claims” debunked by fact-checking companies are widely recognized, but, unsurprisingly, news from mainstream media are more widely recognized than the false claims. This is certainly a good sign, which confirms similar trends reported elsewhere. However, we also found preliminary evidence that misinformation circulates wide on messaging apps. When asked whether and where they encountered researcher-selected false claims, participants reported to be exposed to more false claims than “mainstream claims” (i.e., true) on messaging apps, while this was not the case for traditional media, such as newspapers and TV News. While others have found false claims to be more prevalent on social media than on mainstream media, this is the first systematic evidence that messaging apps might be the primary source for spread of misinformation."
