Does Political Affiliation Trump Outcome Bias? 1 Does Political Affiliation Trump Outcome Bias? Evan D. Lester Department of Psychology Hampden-Sydney College Does Political Affiliation Trump Outcome Bias? 2 Abstract Research in the field of judgment and decision making has consistently shown that information pertaining to the outcome of a decision has a significant impact on people’s attitudes of the decision itself. This effect is referred to as outcome bias. Data was collected from approximately equal numbers of Republicans and Democrats. Participants were presented with descriptions and outcomes of decisions made by a hypothetical politician. The decisions concerned public policies in response to the Coronavirus (COVID-19) pandemic. Participants evaluated the quality of the thinking that went into each decision. Results showed that policies that yielded successful outcomes received significantly better evaluations than policies that yielded failures. Democrats exhibited this tendency to a greater extent compared to Republicans. Conversely, Republicans exhibited a greater bias toward their own political party than did Democrats. The findings of this project are discussed within the context of classic and contemporary findings in the field of judgment and decision making. Keywords: Outcome Bias, Hindsight Bias, Political Affiliation Does Political Affiliation Trump Outcome Bias? 3 Does Political Affiliation Trump Outcome Bias? Individuals make countless decisions every day. Some decisions are trivial (i.e. what to eat) while other decisions can impact many people (i.e. public policy decisions). But how do individuals decide what makes a good or bad decision? In explaining how individuals evaluate decision quality, expected utility theory (EUT) suggests that individuals are rational and deliberate in their estimates of the options available. -
Selective Hypothesis Testing

KARDES University ofCincinnati, Cincinnati, Ohio and SUSAN p. MANTEL University ofToledo, Toledo, Ohio A diverse set ofbiases that have been found to characterize judgment may be similarly mediated by a process ofselective hypothesis testing. Ourpaper begins with a definition ofselective hypothesis test ing and an explanation ofhow andwhen this process leads to error.

Although the psychological literature suggests that selec tive hypothesis testing contributes to a variety of errors, in many contexts it may be a useful and effi cient strategy that leads to satisfactory judgment.

Political Media Bias in US Newscasts Lea Bernhardt Ralf Dewenter Tobias Thomas Zusammenfassung / Abstract We investigate if four leading, electronic news gathering organizations in the US – ABC News, CBS News, FOX News, and NBC News – fulfill their role as the fourth estate in the US democracy. Our analysis, using the Political Coverage Index (PCI) introduced by Dewenter et al (2020), is based on the tonality of their political coverage using 815,000 human-coded news items from 2001 through 2012. For our econometric analysis, we use panel regressions with media and time fixed effects. -

Sanders, Dean of Graduate Studies Date POLITICAL DISCUSSIONS AND THE MEDIA ABSTRACT This study looked to expand on previous research on the hostile media effect. Looking at the predictors of perceived hostility and effects of partisanship and perceived hostility to determine the implications for political engagement. Unlike other studies on the hostile media effect, this study was a qualitative one. The methodology provided very interesting results on the perception of bias, political engagement, and also a unique look at the perception of bias by Republican women. The study found that there are specific decisions strong partisans make when deciding whether or not to discuss politics. It was found that identification with a group and anticipating third person effects leads people to engage differently in face-to-face and on social media, and that these differences were evidence of the hostile media effect. -
Omission Neglect and the Bias Blind Spot: Effects of the Self-Other Asymmetry in Susceptibility to Bias and Responsiveness to Debiasing
Omission Neglect and the Bias Blind Spot: Effects of the Self-Other Asymmetry in Susceptibility to Bias and Responsiveness to Debiasing A dissertation submitted to the Division of Research and Advanced Studies of the University of Cincinnati In partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY (PH.D.) IN THE DEPARTMENT OF MARKETING of the College of Business 2011 By Xiaoqi Han M.A., Marquette University Committee Chair: Frank R. Kardes, Ph.D. i ABSTRACT Omission Neglect and the Bias Blind Spot: Effects of the Self-Other Asymmetry in Susceptibility to Bias and Responsiveness to Debiasing By Xiaoqi Han Chair: Dr. Frank R. Kardes Research on the bias blind spot shows that people are less capable of identifying biases in their own judgment than in others. People generally believe that they are less susceptible to biases than their peers and average people. This dissertation investigates the self-other bias asymmetry with respect to omission neglect. Omission neglect refers to insensitivity to missing or unknown information. Results from bias blind spot research imply a potential relationship between the self-other asymmetry in bias belief and omission neglect. Research on bias correction suggests that people holding a higher degree of asymmetry in bias beliefs may be less likely to correct biases even when omissions are made noticeable. Ironically, consumers who believe that they are less vulnerable to omission neglect may be more susceptible to omission neglect. Consumers may be also less likely to correct their judgment even when omitted information is made noticeable. The goal of the dissertation is to develop debiasing techniques to debias omission neglect in order to improve consumer judgment and decision making. -
THE HOSTILE MEDIA EFFECT in a GLOBAL PERSPECTIVE the Hostile Media Effect in Lebanon: Differences in Perceptions of Western
THE HOSTILE MEDIA EFFECT IN A GLOBAL PERSPECTIVE The Hostile Media Effect in Lebanon: Differences in Perceptions of Western and Arabic News Sources Nicole van Batenburg 10510028 Master’s Thesis Graduate School of Communication Master’s Programme Political Communication Supervisor: Penny Thibaut Sheets 28/02/2019 THE HOSTILE MEDIA EFFECT IN A GLOBAL PERSPECTIVE Abstract The hostile media effect -defined as the tendency for individuals with a strong preexisting attitude on an issue to perceive media coverage as biased against their side and in favor of their opponents’ point of view- has mostly been studied in the context of traditional media (i.e., print and radio) within a specific nation. Nowadays, however, globalization of media is more actual than ever. Polarization, fragmentation and mediatization of society have increasingly become prevalent, yet little is known about the effects of these developments on people’s perception of foreign news sources. This study investigated whether a news source can create a HME in a global setting, and if this effect is moderated by political ideology or political engagement. Participants were randomly assigned to one of three conditions in which they read an identical article about Middle-Eastern affairs, but the news source was varied between a Western, non- Western or Lebanese newspaper. Results indicated the existence of a HME between a Western and Lebanese news source, independent of participants’ political ideology or political engagement. No results were found for the existence of a HME between a Western and Non- Western news source, nor between a Non-Western and Lebanese news source. Overall, this study highlights the importance of studying the HME on a global scale, and calls for more research into its consequences and implications for the fragmentation of the global media landscape. -

Indeed the creation and belief of misinformation, and the apparent public rejection of corrections, during campaigns such as the British EU referendum and the 2016 US presidential election, has led to many now describing the political environment as having entered an era of ‘post-truth politics’. The proliferation of politically motivated misinformation, and the failure of evidence and fact- checking to correct it, can be seen to many as providing a fundamental challenge to the democratic ideals of rational decision making by a well-informed populace. -
