 One review of the CJP data showed that jurors who were asked a hypothetical question regarding how much certain mitigating factors would influence their sentencing decisions were true, 56.2 percent of the jurors would consider a lesser sentence than death if a history of mental illness was presented as a mitigating factor and 73.6 percent would do so if evidence of mental retardation were presented.However, another review of the data showed the race of the victim had a substantial effect on jury failure to find mitigating factors.If the victim were white there was more failure to find mitigating factors.
