Learning about informal fallacies and the detection of fake news: an experimental intervention
(2023)
The philosophical concept of informal fallacies–arguments that fail to provide sufficient support for a claim–is introduced and connected to the topic of fake news detection. We assumed that the ability to identify informal fallacies can be trained and that this ability enables individuals to better distinguish between fake news and real news. We tested these assumptions in a two-group between-participants experiment (N = 116). The two groups participated in a 30-minute-long text-based learning intervention: either about informal fallacies or about fake news. Learning about informal fallacies enhanced participants’ ability to identify fallacious arguments one week later. Furthermore, the ability to identify fallacious arguments was associated with a better discernment between real news and fake news. Participants in the informal fallacy intervention group and the fake news intervention group performed equally well on the news discernment task. The contribution of (identifying) informal fallacies for research and practice is discussed.
This paper intends to trace the introduction of an English-induced, COVID-related neologism, covidiota, into the Spanish language. The study is based on a corpus of tweets, starting in March 2020. It examines several specific features which mark the word as a new, unfamiliar item, such as different ways of graphical highlighting, for example. On the other hand, the paper aims to detect possible indicators of an integration of covidiota into the Spanish language use in the tweet corpus compiled for this case study.
