Stand your ground (SYG) and castle doctrine (CD) laws are presently growing throughout the United States. The present study aims to better understand public perceptions of SYG and CD cases and demographic factors that influence judicial decision making.Results indicated participants were more likely to assign a guilty verdict to the SYG scenario, compared to the CD scenario. Additionally, participants assigned to the SYG vignette believed the male defendant was more justified in killing the victim, compared to participants assigned the female defendant.Results from this study reveal how potential jurors may harbor sex/gender bias in determining justifiable homicide in stand your ground cases.
