Collection and especially analysis of open‐ended survey responses are relatively rare in the discipline when conducted almost exclusively done through human coding. We present an alternative, semiautomated approach, structural topic model (STM) (Roberts, Stewart, Airoldi 2013; Roberts et al. 2013), that draws on recent developments machine learning based textual data. A crucial contribution method is it incorporates information about document, such as author's gender, political affiliation,...
Across two studies with more than 1,700 U.S. adults recruited online, we present evidence that people share false claims about COVID-19 partly because they simply fail to think sufficiently whether or not the content is accurate when deciding what share. In Study 1, participants were far worse at discerning between true and would on social media relative asked directly accuracy. Furthermore, greater cognitive reflection science knowledge associated stronger discernment. 2, found a simple...
The 2016 U.S. presidential election brought considerable attention to the phenomenon of "fake news": entirely fabricated and often partisan content that is presented as factual. Here we demonstrate one mechanism contributes believability fake news: fluency via prior exposure. Using actual fake-news headlines they were seen on Facebook, show even a single exposure increases subsequent perceptions accuracy, both within same session after week. Moreover, this "illusory truth effect" for occurs...
Significance Many people consume news via social media. It is therefore desirable to reduce media users’ exposure low-quality content. One possible intervention for ranking algorithms show relatively less content from sources that users deem be untrustworthy. But are laypeople’s judgments reliable indicators of quality, or they corrupted by either partisan bias lack information? Perhaps surprisingly, we find laypeople—on average—are quite good at distinguishing between lower- and...
The public goods game is the classic laboratory paradigm for studying collective action problems. Each participant chooses how much to contribute a common pool that returns benefits all participants equally. ideal outcome occurs if everybody contributes maximum amount, but self-interested strategy not anything. Most previous studies have found punishment be more effective than reward maintaining cooperation in games. typical design of these studies, however, represses future consequences...
A poisonous cocktail of othering, aversion, and moralization poses a threat to democracy
Fake news represents a particularly egregious and direct avenue by which inaccurate beliefs have been propagated via social media. We investigate the psychological profile of individuals who fall prey to fake news.We recruited 1,606 participants from Amazon's Mechanical Turk for three online surveys.The tendency ascribe profundity randomly generated sentences-pseudo-profound bullshit receptivity-correlates positively with perceptions accuracy, negatively ability differentiate between real...
Human populations are both highly cooperative and organized. interactions not random but rather structured in social networks. Importantly, ties these networks often dynamic, changing response to the behavior of one's partners. This dynamic structure permits an important form conditional action that has been explored theoretically received little empirical attention: People can respond cooperation defection those around them by making or breaking network links. Here, we present experimental...
What can be done to combat political misinformation? One prominent intervention involves attaching warnings headlines of news stories that have been disputed by third-party fact-checkers. Here we demonstrate a hitherto unappreciated potential consequence such warning: an implied truth effect, whereby false fail get tagged are considered validated and thus seen as more accurate. With formal model, Bayesian belief updating lead effect. In Study 1 (n = 5,271 MTurkers), find although do modest...
Some have argued that belief in God is intuitive, a natural (by-)product of the human mind given its cognitive structure and social context. If this true, extent to which one believes may be influenced by one's more general tendency rely on intuition versus reflection. Three studies support hypothesis, linking intuitive style God. Study 1 showed individual differences predict Participants completed Cognitive Reflection Test (CRT; Frederick, 2005), employs math problems that, although easily...
