This experiment uses the Community of Knowledge framework to better understand how jurors interpret new information (Sloman & Rabb, 2016). Participants learned of an ostensibly new scientific finding that was claimed to either be well-understood or not understood by experts. Despite including no additional information, expert understanding led participants to believe that they personally understood the phenomenon, with expert understanding acting as a cue for trustworthiness and believability. This effect was particularly pronounced with low-quality sources. These results are discussed in the context of how information is used by jurors in court, and the implications of the “Community of Knowledge” effect being used by expert witnesses.

This study hypothesizes that prosecutors would be more likely to prosecute juveniles who engage in sexual activity with an underage same-sex partner than those who engage in underage sexual activity with a member of the opposite sex. To test this hypothesis, surveys were mailed to 1,000 prosecutors around the United States with a between subject design, meaning that each participant was only exposed to one condition in the vignette they read. There were a total of four vignettes, creating four conditions of different “offender” sex and “victim” sex in sexually appropriate relationships. The vignettes contain conditions in which either a male or female junior in high school was videotaped having oral sex with either a male or a female freshman in high school. Prosecutors were asked questions about whether they would prosecute the older student for statutory rape. Results indicated that manipulations of “offender” sex and “victim” sex were not statistically significant on prosecutorial discretion or punishment severity/motives; however, these manipulations did alter the prosecutors’ perceptions of the offender.

The previous research literature was reviewed on how perpetrator's group membership and individuals' racial identity impact intergroup attitude and behavior, as well as factors contribute to intergroup bias on individuals' empathy level. This study was designed to extend the existing research on intergroup relations by exploring the effect of perpetrator's ingroup/outgroup membership and the strength of racial identity on people's empathy toward the outgroup victims. A web-based survey was disseminated and administrated at a southwest university. One hundred and six Caucasian American college students who completed the survey and met the criterion of eighteen years old or older were involved in this study. Participants were randomly assigned to read one of two target stories and one distracter story, and reported their empathy level toward each story. And then the participants' strength of racial identity was measured.

Controlling for demographic variables, regression analyses revealed that, as expected, the interaction of the perpetrator's group membership and individuals' racial identity significantly predicted the level of empathy toward the outgroup victim. When the perpetrator was an ingroup member, people who highly identified with their group exhibited less empathy for the outgroup victim. However, perpetrator's membership and the strength of racial identity failed to predict individuals' outgroup empathy separately.
