Debiasing media articles–reducing hindsight bias in the production of written work.

2021

Written work such as Wikipedia articles can contain hindsight bias. Since reading biased texts can, in turn, increase recipients’ individual hindsight bias, it is an important agenda to examine effective debiasing strategies. In the present study (N = 164), we tested whether providing authors with debiasing strategies can effectively reduce hindsight bias in their content. Specifically, participants wrote an article based on several newspaper articles about a dam and we manipulated whether they received event knowledge (i.e., dam collapse) and a debiasing intervention. Ten blind coders rated the extent to which the produced articles were suggestive of the disaster. Debiasing was successful …

Early-Career Researchers’ Perceptions of the Prevalence of Questionable Research Practices, Potential Causes, and Open Science

2017

Abstract. Young researchers of today will shape the field in the future. In light of current debates about social psychology’s research culture, this exploratory survey assessed early-career researchers’ beliefs (N = 88) about the prevalence of questionable research practices (QRPs), potential causes, and open science as a possible solution. While there was relative consensus that outright fraud is an exception, a majority of participants believed that some QRPs are moderately to highly prevalent what they attributed primarily to academic incentive structures. A majority of participants felt that open science is necessary to improve research practice. They indicated to consider some open s…

The winner knew it all? Conspiracy beliefs and hindsight perspective after the 2016 US general election

2018

Abstract The political campaigns preceding the 2016 U.S. Presidential Election received worldwide media attention that many people followed with great interest. Before the election, there were rumors of how the outcome of this election might be rigged, there was additional suspicion that individuals who were not eligible to vote were seen at voting booths, and other assumptions that might be connected to a conspiracy mentality. In this contribution, we report the results of one case study (N = 173) regarding inter-individual differences in conspiracy mentality, uncertainty, and hindsight perceptions of inevitability and foreseeability between voters of the major parties' candidates, namely,…

The Norm of Neutrality in Collaborative Knowledge Construction

2017

Social media enabled collaboration at unprecedented levels. And while research points to the benefits of mass collaboration, it has also revealed challenges and problems. Here we explore biases in collaboratively constructed knowledge. To this end, we compared two online encyclopedias: Wikipedia and the extreme right-wing Metapedia. Both urge users to present topics from a neutral point of view. Using different measures we found that Metapedia articles (vs. Wikipedia articles) are significantly shorter, contain fewer references, contain relatively more anger- and anxiety-related words, rarely present more than one point of view in controversies, and often convey opinions – for inctance, by …

What drives increases in hindsight impressions after the reception of biased media content?

2021

Prior research has shown that reading biased media content (e.g., Wikipedia articles) can increase recipients' hindsight bias. It remained unclear, however, which features of the biased texts led to such an increase. We examined this question in a longitudinal experimental study (N = 190). Specifically, we tested whether repeated exposure to already known information (H₁), a more coherent presentation of the information (H₂), or the presentation of novel information (H₃) affected readers' hindsight impressions of likelihood, inevitability, and foreseeability. To this end, participants initially learned about an event by reading several short news, and, 1 week later, received one of several …

Emotions in Wikipedia: the role of intended negative events in the expression of sadness and anger in online peer production

2018

ABSTRACTThe online encyclopaedia Wikipedia has strict guidelines for ensuring the objectivity of its content and unbiased language of its articles. Wikipedia also provides articles on negative even...

Rich false memories of autobiographical events can be reversed

2021

False memories of autobiographical events can create enormous problems in forensic settings (e.g., false accusations). While multiple studies succeeded in inducing false memories in interview settings, we present research trying to reverse this effect (and thereby reduce the potential damage) by means of two ecologically valid strategies. We first successfully implanted false memories for two plausible autobiographical events (suggested by the students’ parents, alongside two true events). Over three repeated interviews, participants developed false memories (measured by state-of-the-art coding) of the suggested events under minimally suggestive conditions (27%) and even more so using massi…

Emotional Content in Wikipedia Articles on Negative Man-Made and Nature-Made Events

2017

Wikipedia emphasizes the objectivity of content. Yet, Wikipedia articles also deal with negative events that potentially elicit intense emotions. Undesirable outcomes (e.g., earthquakes) are known to elicit sadness, while undesirable outcomes caused by others’ actions (e.g., terrorist attacks) are known to elicit anger. Internet users’ emotional responses are likely to end up in Wikipedia articles on those events as characteristics of Internet users spill over to Wikipedia articles. Therefore, we expected that Wikipedia articles on terrorist attacks contain more anger-related and less sadness-related content than articles on earthquakes. We analyzed newly created Wikipedia articles about t…

Believe It or Not – No Support for an Effect of Providing Explanatory or Threat-Related Information on Conspiracy Theories’ Credibility

2021

Past research suggests that certain content features of conspiracy theories may foster their credibility. In two experimental studies (N = 293), we examined whether conspiracy theories that explicitly offer a broad explanation for the respective phenomena and/or identify potential threat posed by conspirators are granted more credibility than conspiracy theories lacking such information. Furthermore, we tested whether people with a pronounced predisposition to believe in conspiracies are particularly susceptible to such information. To this end, participants judged the credibility of four conspiracy theories which varied in the provision of explanatory and threat-related information. Intere…

Cultural Interpretations of Global Information? Hindsight Bias after Reading Wikipedia Articles across Cultures

2017

Summary: Hindsight bias is the mistaken belief that an outcome could have been foreseen once it is known. But what happens after learning about an event? Can reading biased media amplify hindsight distortions? And do people from different cultural backgrounds — with different cognitive thinking styles — draw equal conclusions from equal media reports? We report two studies with Wikipedia articles and samples from different cultures (Study 1: Germany, Singapore, USA, Vietnam, Japan, Sweden, N = 446; Study 2: USA, Vietnam, N = 144). Participants read one of two article versions (foresight and hindsight) about the Fukushima Nuclear Plant and estimated the likelihood, inevitability, and foresee…
