Research being conducted by John Gottman (2010) and his colleagues involves inviting married couples into a pleasant setting, in which they revisit the disagreement that caused their last argument. Although the participants are aware that they are being videotaped, they soon become so absorbed in their own interaction that they forget they are being recorded. With the second-by-second analysis of observable reactions as well as emotional ones, Gottman is able to predict with 93% accuracy the fate of the couples' relationship.
