The term gender bias was coined by the National Judicial Education Program to Promote Equality for Women and Men in the Courts and is defined as the predisposition or tendency to think about and behave toward people primarily on the basis of their sex rather than their status, professional accomplishments, or aspirations. An effective method for documenting the extent and nature of gender bias is the task force approach. Data collection methods used in task force studies included: (1) interviews with judges; (2) analysis of statistical materials from the administrative office of the courts and other state and federal agencies; (3) review of cases on substantive law in the areas of damages, domestic violence, juvenile justice, matrimonial law, and sentencing; (4) surveys on gender bias at state bar association regional meetings; and (5) surveys distributed to attorneys throughout the United States. Several states that carried out task force studies of gender bias have reported similar findings. Women receive unequal treatment in the areas of divorce, domestic violence, personal injury litigation, rape, and juvenile justice. Women attorneys, judges, and employees of the courts receive demeaning and unequal treatment from other attorneys and judges. All the task force studies made recommendations to sensitize court officers about the problem of gender bias and to ameliorate the effects of such bias. (SM)
