The Web 2.0 enabled collaboration at an unprecedented level. In one of the flagships of mass collaboration—Wikipedia—a large number of authors socially negotiate the world’s largest compendium of knowledge. Several guidelines in Wikipedia restrict contributions to verifiable information from reliable sources to ensure recognized knowledge. Much psychological research demonstrates, however, that individual information processing is biased. This poses the question whether individual biases… 
Wikipedia outperforms individuals when it comes to hindsight bias
These findings are the first to demonstrate Wikipedia’s superiority over individuals when it comes to hindsight bias, and there was substantial support for the null hypothesis (i.e., no hindsight bias) in Wikipedia.
Cultural Interpretations of Global Information? Hindsight Bias after Reading Wikipedia Articles across Cultures
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
Collectively biased representations of the past: Ingroup Bias in Wikipedia articles about intergroup conflicts.
This paper is the first to demonstrate ingroup bias in Wikipedia - a finding that is of practical as well as theoretical relevance as it outline in the discussion.
Debiasing Media Articles – Reducing Hindsight Bias in the Production of Written Work
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
The Norm of Neutrality in Collaborative Knowledge Construction
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
The Impact of Topic Characteristics and Threat on Willingness to Engage with Wikipedia Articles: Insights from Laboratory Experiments
It is demonstrated that topic characteristics were factors that substantially influenced people’s willingness to engage with Wikipedia articles whereas perceived threat was not.

People often evaluate in-group members, who deviated from socially accepted norms, more harshly than outgroup members who performed the same misconduct. The present paper investigates whether or not
Psychology and Wikipedia: Measuring Psychology Journals’ Impact by Wikipedia Citations

Multiple Texts as a Limiting Factor in Online Learning: Quantifying (Dis-)similarities of Knowledge Networks
The article develops a hybrid model of intra- and intertextual similarity of different parts of the information landscape and tests this model on the example of 35 languages and corresponding Wikipedias, and goes beyond existing approaches by examining their structural and semantic aspects intra-and intertextually.


Individual Versus Collaborative Information Processing: The Case of Biases in Wikipedia
Psychology has accumulated ample evidence for the notion that individual information processing is biased. Little is known, however, about “collective biases.” The chapter presented here takes the
How many hindsight biases are there?
It is argued that the hindsight bias is not a unitary phenomenon but consists of three separable and partially independent subphenomena or components, namely, memory distortions, impressions of foreseeability and impressions of necessity, which are investigated in the context of political elections.
The hindsight bias: A meta-analysis
Abstract The hindsight bias in probability assessments is one of the most frequently cited judgment biases. A meta-analysis of 122 studies revealed evidence that the bias occurs under some conditions
Hindsight bias around the world.
It is suggested that the basic cognitive processes leading to hindsight bias are by-products of the evolutionary-evolved capacity of adaptive learning, and individual meta-cognitions or motives may further moderate the amount of bias.
Surprise, defence, or making sense: What removes hindsight bias?
It is suggested that a sense of responsibility for the outcome may be necessary for defensive processing to be activated and a proposed sense-making model suggests that unexpected outcomes invoke greater sensemaking, which typically produces greater hindsight bias.
Cultural bias in Wikipedia content on famous persons
The extent to which content and perspectives vary across cultures is examined by comparing articles about famous persons in the Polish and English editions of Wikipedia, revealing systematic differences related to the different cultures, histories, and values of Poland and the United States.
Causality as an influence on hindsight bias: An empirical examination of judges' evaluation of professional audit judgment

Expectation-outcome consistency and hindsight bias

A cross-cultural study of hindsight bias and conditional probabilistic reasoning
Hindsight bias is a mistaken belief that one could have predicted a given outcome once the outcome is known. Choi and Nisbett (2000) reported that Koreans showed stronger hindsight bias than
