Moral foundations and juror verdict justifications

The purpose of this study was to examine the ways in which mock jurors justified their verdict decisions using moral foundations language. Participants read a trial transcript describing a second-degree murder charge featuring an automatism plea (which negates the physical volition of a crime). They then provided a two-to-three sentence rationale for their verdict choice, which we coded for the contextually-valid presence of words from the Moral Foundations (MF) Dictionary. Mock jurors were most likely to use harm-related language in justifying murder votes. A qualitative description also revealed differences in the content of the justifications.
