technically as “positive sentiment override,” or PSO, a concept first proposed by University of Oregon psychologist Robert Weiss. This means that their positive thoughts about each other and their marriage are so pervasive that they tend to supersede their negative feelings. It takes a much more significant conflict for them to lose their equilibrium as a couple than it would otherwise. Their positivity causes them to feel optimistic about each other and their marriage, to have positive expectations about their lives together, and to give each other the benefit of the doubt.
