Judging a book by its cover: understanding the phenomenon of fake news propagation from an evolutionary psychology perspective

With fake news now a serious concern facing researchers, practitioners, and policymakers alike, research is increasingly exploring the factors that lead to its proliferation. However, there is limited research on the role of temporal orientation. i.e., emphasis on time. This paper examines whether a future temporal orientation (FTO), defined as a relative emphasis on the future observed in fake news titles and content, is associated with fake news sharing. We bring arguments grounded in evolutionary psychology to understand the underlying rationale driving this phenomenon. Our analysis of a Twitter dataset comprising 465519 tweets suggests that FTO characterizes fake news and is positively associated with fake news sharing. Notably, fake news titles and the accompanying text differ in their FTO. Specifically, we show an inverted U-shaped relationship between fake news sharing and the difference in FTO between the title and accompanying text. As a practical implication of this analysis, efforts to limit the spread of fake news should pay more attention to how such news emphasizes the future.
