![]() ![]() This effect has been attributed to various factors, including less systematic information processing and reduced information search under time pressure 18. Generally, faster responses come at the expense of reduced discrimination ability 15. Previous research on the role of decision timing has found strong support for a speed–accuracy trade-off across various contexts 15, 16, 17. Specifically, we investigated how time pressure influences (a) the ability to distinguish between true and false news (i.e., discrimination ability in the context of misinformation), (b) the tendency to classify an item as true or false (i.e., response bias), and (c) the effects of four potential drivers of susceptibility to misinformation on (a) and (b). Here, we assess the effect of time pressure-an important corollary of accelerating online dynamics-on people’s susceptibility to misinformation. With increasing numbers of people sourcing and sharing news on social media 10, there is growing public and scholarly concern surrounding the digital spread of misinformation 11, 12, 13, 14. The psychological implications of this information overload 9 are largely unclear, especially with respect to people’s ability to detect misinformation online. These accelerating online dynamics are likely to be driven by the increasing production and consumption of content: Social media users are consuming ever more content like news in ever shorter time spans 2, 3, 8. Acceleration has also been observed at the level of the individual, with later-joining Twitter cohorts being more active (e.g., posting more tweets over time) and switching their focus to new topics more quickly 7. ![]() 2 found evidence for increasingly faster flows of collective attention on cultural items (e.g., via hashtags on Twitter and comments on Reddit see also 4, 5, 6). Analysing content consumption across multiple platforms (e.g., Twitter and Reddit) over the course of a decade, Lorenz-Spreen et al. Interventions aimed at increasing deliberation may thus be fruitful avenues to combat online misinformation.Ī growing body of research has started to suggest that various parts of our social lives are speeding up, a phenomenon referred to as social acceleration 1, 2, 3. Our results highlight the dangers of social acceleration online: People are less able to accurately judge the veracity of news online, while prominent drivers of misinformation susceptibility remain present. ![]() Key drivers of misinformation susceptibility, such as ideological congruency and familiarity, remained influential under time pressure. Time pressure reduced participants’ ability to accurately distinguish true from false news (discrimination ability) but did not alter their tendency to classify an item as true or false (response bias). We used signal detection theory to disentangle the effects of time pressure on discrimination ability and response bias, as well as on four key determinants of misinformation susceptibility: analytical thinking, ideological congruency, motivated reflection, and familiarity. Participants judged the veracity of true and false news headlines with or without time pressure. We examined the effects of accelerated online dynamics, operationalised as time pressure, on online misinformation evaluation. How social acceleration impacts people’s ability to judge the veracity of online news, and ultimately the spread of misinformation, is largely unknown. Many parts of our social lives are speeding up, a process known as social acceleration. ![]()
