A study reveals that demonstrating the falsehood of a news item is more effective than eliminating it in the battle against misinformation. The analysis is based on 1,468 newspaper articles that spread false information about health-related topics.

The main conclusion is that the implementation of X's policy, launched for the first time in 2021 under the name Birdwatch, manages to reduce the spread of this fake news. Posts that include links to disinformation articles are less likely to be retweeted, quoted or commented on. This effect is mainly noticeable in that there are fewer cases of real people sharing links to dubious information. However, it does not affect accounts managed by bots or accounts of disinformation super-spreaders. The changes implemented by Elon Musk in security and content moderation policies after acquiring Twitter have led to the platform being considerably less reliable than before, according to various verification experts. In her opinion, the most appropriate thing would be to apply the nudge nudge approach to cases in which the disinformation affects essential aspects such as public safety and public safety.
