A search around news items sometimes relying on prior knowledge helps to determine credible information and sources. Detecting fake and/or manipulated pictures is relatively easy with apps for that.
However, the COVID-19 crisis taught us a lot in African Library and Information Associations and Institutions (AfLIA). We learned that librarians are prone to go with the crowd as fantastic stories of cures for COVID-19 were spread as WhatsApp messages from unidentified sources and conspiracy theories about vaccines flew everywhere. The heap of disinformation was huge.
AfLIA ran a 5day Media and Information Literacy online course (https://web.aflia.net/2020-global-media-and-information-literacy-week-short-course/ ) for African librarians to engage their minds on how to resist the disinfodemic brought on by the pandemic and how to dissuade people from doubting the purpose of vaccines. It's an ongoing exercise as some of the participants are still carrying out their Action Plans to help their user communities understand the facts around COVID-19 !
