The relatively small body of prior research investigating whether the sex composition of juries impacts sentencing decisions has produced equivocal results. Exploring this topic further, the current study used a large sample of capital cases from North Carolina (n = 675) to examine (a) whether jury sex composition predicted jury capital punishment sentencing decisions; and (b) whether there were different models of sentencing for male-majority, equal male-female, and female-majority juries. When we controlled for a number of legal and extralegal factors, our findings indicated that jury sex composition was independently related to sentencing outcomes. Specifically, equal male-female juries were significantly more likely and female-majority juries were significantly less likely to choose the death penalty versus a sentence of life in prison. In addition, different models (predictors) of sentencing were revealed for each of the jury sex compositions. Implications for future research and policy are discussed.
