Juror decision-making within domestic sex trafficking cases: do pre-trial attitudes, gender, culture and right-wing authoritarianism predict believability assessments?

Purpose This study aims to examine whether country of residence, sex trafficking attitudes, complainant gender, juror gender and right-wing authoritarianism (RWA) influenced juror decision-making within a sex trafficking case. Design/methodology/approach Jury-eligible participants from the USA and the UK participated in an online juror experiment in which an independent group design was used to manipulate the complainant’s gender. Participants completed the juror decision scale, the sex trafficking attitudes scale and the RWA scale. Findings Sex trafficking attitudes predicted the believability of both the defendant and complainant. Greater negative beliefs about victims predicted greater defendant believability and lower complainant believability. US jurors reported greater believability of both the complainant and defendant, and RWA was associated with greater defendant believability. However, none of the other factors, including complainant and juror gender, predicted participants’ verdicts. The findings suggest juror verdicts in sex trafficking cases may be less influenced by extra-legal factors, although further research is needed, especially with a more ambiguous case. Originality/value This is one of the few cross-cultural comparison studies in the area of jury decision-making, specifically regarding sex trafficking cases. The findings indicated that US participants held more problematic attitudes about sex trafficking than their UK counterparts, although all participants held problematic attitudes about sex trafficking. However, those attitudes did not affect verdict formation about either a male or female complainant. Participants who were more knowledgeable about sex trafficking reported greater complainant believability, suggesting that educational interventions may provide greater support for victims in court.
