People are biased in their consumption of scientific information. The current research investigated conclusion thresholds, testing the hypothesis that more scientific evidence is needed to arrive at a non-preferred than a preferred conclusion. Participants read brief summaries of scientific studies exploring the nature of homosexuality (Study 1; N = 126) and air safety that supported either the Democratic or the Republican position on the issue (Study 2; N = 311). Participants read summaries until a conclusion could be made about the evidence. Supporting the hypotheses, participants read fewer study summaries when the results of those studies supported their preferred conclusion than when they did not. Recommendations focus on how the scientific community and science journalism can address this bias. [ABSTRACT FROM AUTHOR]

The relationship between personality traits and biased assimilation, evaluating arguments, and persuasive messages more favorably if supporting pre‐existing attitudes, lacks adequate research. Research suggests that higher narcissistic traits are associated with biased reactions. Additionally, research suggests that people with greater scientific reasoning abilities have more biased reactions to information that challenges their attitude, as they more easily locate flaws on topics that oppose their beliefs. Participants (N = 260) completed measures to identify their views on trans bathroom use, as well as other personality and attitude measures. They were randomly assigned to read one of the two articles using fake scientific data that either supported trans people using a bathroom reflecting their gender identity or that they should use a bathroom matching their sex‐assigned at birth. Participants rated the quality of the article significantly higher when their opinion on bathroom use was congruent with the article than when it was incongruent. We used regression analyses with participants' perceptions of the quality of the article as the outcome variable and scientific reasoning scores, narcissism personality index scores, open‐mindedness scores as predictor variables. In the mismatch group, the higher the scores on scientific reasoning, the lower the ratings of the quality of the opinion incongruent article. In the match group, the higher the scores on open‐mindedness, the lower the ratings of the quality of the opinion congruent article. This research suggests that bias reduction is necessary to function in a world where scientific facts are called into question on a consistent basis. [ABSTRACT FROM AUTHOR]

Students often have little understanding of the role psychological science plays in informing us about the impact of human behavior when addressing climate change. We designed an assignment for a social psychology course based on Frantz and Mayer’s use of the decision tree model of helping behavior to identify the psychological barriers that reduce the likelihood that people will take action against climate change. Students identified one barrier and designed a persuasion or influence attempt to address that barrier. The assignment integrated social psychological topics in several areas (e.g., helping behavior, persuasion). A pretest–posttest design revealed that students’ knowledge of the role of psychological science in understanding climate change increased compared to a control class. [ABSTRACT FROM AUTHOR]

This study tested the effectiveness of video game use for instruction of factorial designs in a research methods course. Students designed and conducted a mini study, playing Dance, Dance, Revolution, using video game scores as the dependent variable. A mixed-design analysis of variance revealed a significantly greater increase from pretest to posttest in content knowledge in the Wii activity condition compared to lecture-only and no-content control conditions. Implementing this nontraditional teaching method engaged students and increased knowledge of factorial designs in a research method course. [ABSTRACT FROM PUBLISHER]

Two methods by which people make prejudicial yet justifiable judgments were assessed in a simulated college admissions paradigm in which participants evaluated 2 applications. In the preference condition, the stronger applicant was described as a member of a different political party than the participant. In the control condition, no political party was indicated. Supporting a political partisan prejudice effect, among strong partisans, the stronger applicant was favored in the control condition, but the weaker applicant was favored in the preference condition. No effect was found for weak partisans. Additionally, participants supported their biases by altering the importance of (Study 1) and distorting the strength of (Study 2) different types of application information. [ABSTRACT FROM AUTHOR]

The scientific impotence discounting hypothesis predicts that people resist belief-disconfirming scientific evidence by concluding that the topic of study is not amenable to scientific investigation. In 2 studies, participants read a series of brief abstracts that either confirmed or disconfirmed their existing beliefs about a stereotype associated with homosexuality. Relative to those reading belief-confirming evidence, participants reading belief-disconfirming evidence indicated more belief that the topic could not be studied scientifically and more belief that a series of other unrelated topics could not be studied scientifically. Thus, being presented with belief-disconfirming scientific evidence may lead to an erosion of belief in the efficacy of scientific methods. [ABSTRACT FROM AUTHOR]

The present study examined whether individuals' current political worldviews would bias perceptions of historical information gathered over the course of their lifetime. Kent State University students from 1995 and 2000 reported their political ideologies (e.g., conservative, liberal) and responded to items assessing their culpability and global attributions about the shooting of demonstrators by the National Guard at Kent State in 1970. The 1995 data revealed consistent support for biased responding to culpability and global attribution items. The 2000 data replicated the political ideology differences of the 1995 data. However, by including knowledge of the incident as an independent variable, the 2000 data revealed that the political ideology bias was strongest among people reporting high knowledge about the event.

The tendency for people to rate attitude-confirming information more positively than attitude-disconfirming information (biased assimilation) was studied in a naturalistic context. Participants watched and evaluated the first 1996 Presidential Debate between Bill Clinton and Bob Dole. Regression analyses revealed that predebate attitudes but not expectations predicted postdebate argument evaluations and perceived attitude change. Participants evaluated the arguments that confirmed their predebate attitudes as being stronger than the arguments that disconfirmed their predebate attitudes, and they perceived their postdebate attitudes to have become more extreme than their predebate attitudes. Self-reported affective responses mediated the association between predebate attitudes and postdebate argument evaluations. The role of affect in information-processing theories and the significance of the findings for sociopolitical debates are discussed. [ABSTRACT FROM AUTHOR]

If preference-inconsistent information initiates more effortful cognitive analysis than does preference-consistent information, then people should be more sensitive processors of information they do not want to believe than of information they do want to believe. Three studies supported this prediction. Study 1 found that inferences drawn from favorable interpersonal feedback revealed a correspondence bias, whereas inferences drawn from unfavorable feedback were sensitive to situational constraint. Study 2 showed this sensitivity to the quality of unfavorable feedback to disappear under cognitive load. Study 3 showed that evaluations of the accuracy of favorable medical diagnoses were insensitive to the probability of alternative explanation, whereas evaluations of unfavorable diagnoses were sensitive to probability information. The importance of adaptive considerations in theories of motivated reasoning is discussed. [ABSTRACT FROM AUTHOR]

Prior expectations can lead a person to process information in a biased manner such that the expectations are confirmed. Despite its prevalence in everyday judgments, people lack insight into expectancy confirmation processes. The classroom demonstration we describe uses daily horoscopes to demonstrate the powerful effect that expectations can have on judgments. More students reported that the events of a recent day most closely matched the prediction for their particular astrological sign when the astrological signs were presented along with the predictions than when they were not. Students reported that the demonstration was interesting, and 95% of the students correctly answered a question regarding the phenomenon on a subsequent examination. [ABSTRACT FROM AUTHOR]

This study examined associations between level of sport participation, goal and sportspersonship orientations, and moral reasoning in sport and nonsport situations and orientation by sport participation interactions. Participants were individuals with elite (n = 176), high school (n = 183), and youth sport (n = 78) participation. When judging sport situations, individuals who participated in elite sports demonstrated poorer moral reasoning than those who participated in high school and youth sports. At low levels of sportspersonship, individuals who participated in youth sports demonstrated higher moral reasoning than those who participated in high school and elite sports. When judging nonsport situations, moral reasoning was positively related to positive sportspersonship and negatively related to ego orientation but did not differ by sport participation. Within sport, sport participation and goal and sportspersonship orientations play a critical role in moral reasoning. However, these orientations may be more important than sport participation in moral reasoning beyond the sport context. [ABSTRACT FROM PUBLISHER]
