This research project that you're referring to, “Motives and Methods”, was a project that we designed to test the effectiveness of our “Break the Fake” resources, which are designed to teach quick and easy steps for verifying online information, in the hopes that people will make a habit of verifying all the information they encounter—particularly information that they may use as the basis for important decisions and particularly, as well, before they share information.
This research project demonstrated quite strongly that very limited exposure to this program had significant impacts on people's ability to identify false content but, just as importantly, to identify real content. There is a lot of evidence that it is the discernment between true and false information that is so important in avoiding the backfire risks that sometimes come when we focus excessively on teaching people to debunk false information.
