TLDR
In this article, the authors quantify sentiment differences between true and fake news on social media using a diverse body of datasets from the literature that contains about 100K previously labeled true and false news.Abstract:
The presence of disinformation and fake news on the Internet and especially social media has become a major concern. Prime examples of such fake news surged in the 2016 U.S. presidential election cycle and the COVID-19 pandemic. We quantify sentiment differences between true and fake news on social media using a diverse body of datasets from the literature that contains about 100K previously labeled true and fake news. We also experiment with a variety of sentiment analysis tools. We model the association between sentiment and veracity as conditional probability and also leverage statistical hypothesis testing to uncover the relationship between sentiment and veracity. With a significance level of 99.999%, we observe a statistically significant relationship between negative sentiment and fake news and between positive sentiment and true news. The degree of association, as measured by Goodman and Kruskal's gamma, ranges between .037 to .475. Finally, we make our data and code publicly available to support reproducibility. Our results assist in the development of automatic fake news detectors.read more

Deceptive reviews and sentiment polarity: Effective link by exploiting BERT
TL;DR: In this paper , a multi-label classification methodology based on the Google BERT neural language model is proposed to build a deceptive review detector aided by its sentiment awareness, improved modeling of the link between sentiment polarity and deceptiveness during the fine-tuning phase by exploiting the Binary Cross Entropy with Logits loss function adds to the advantages provided by pre-trained contextual models.

Social Media and Fake News in the 2016 Election
Hunt Allcott,Matthew Gentzkow +1 more
TL;DR: The authors found that people are much more likely to believe stories that favor their preferred candidate, especially if they have ideologically segregated social media networks, and that the average American adult saw on the order of one or perhaps several fake news stories in the months around the 2016 U.S. presidential election, with just over half of those who recalled seeing them believing them.

Nonverbal Leakage and Clues to Deception
Paul Ekman,Wallace V. Friesen +1 more
TL;DR: The study explores the interaction situation, and considers how within deception interactions differences in neuroanatomy and cultural influences combine to produce specific types of body movements and facial expressions which escape efforts to deceive and emerge as leakage or deception clues.

Accuracy of Deception Judgments

TL;DR: It is proposed that people judge others' deceptions more harshly than their own and that this double standard in evaluating deceit can explain much of the accumulated literature.
