Busseri, Choma, and Sadava (2009) asked a sample of participants who scored as pessimists on a measure-of-life survey about their past, present, and projected-future satisfaction with their lives. Higher scores on the life-satisfaction survey indicate higher satisfaction. Do pessimists predict a gloomier future for themselves?
