“See the system. When you find yourself stuck in an oversimplified polarized conflict, a useful first step is to try to become more aware of the system as a whole: to provide more context to your understanding of the terrain in which the stakeholders are embedded, whether they are disputants, mediators, negotiators, lawyers, or other third parties. This can help you to see the forest and the trees; it is a critical step toward regaining some sense of accuracy, agency, possibility, and control in the situation.”

“Most of us do not like not being able to see what others see or make sense of something new. We do not like it when things do not come together and fit nicely for us. That is why most popular movies have Hollywood endings. The public prefers a tidy finale. And we especially do not like it when things are contradictory, because then it is much harder to reconcile them (this is particularly true for Westerners). This sense of confusion triggers in a us a feeling of noxious anxiety. It generates tension. So we feel compelled to reduce it, solve it, complete it, reconcile it, make it make sense. And when we do solve these puzzles, there's relief. It feels good. We REALLY like it when things come together.

What I am describing is a very basic human psychological process, captured by the second Gestalt principle. It is what we call the 'press for coherence.' It has been called many different things in psychology: consonance, need for closure, congruity, harmony, need for meaning, the consistency principle. At its core it is the drive to reduce the tension, disorientation, and dissonance that come from complexity, incoherence, and contradiction.

In the 1930s, Bluma Zeigarnik, a student of Lewin's in Berlin, designed a famous study to test the impact of this idea of tension and coherence. Lewin had noticed that waiters in his local cafe seemed to have better recollections of unpaid orders than of those already settled. A lab study was run to examine this phenomenon, and it showed that people tend to remember uncompleted tasks, like half-finished math or word problems, better than completed tasks. This is because the unfinished task triggers a feeling of tension, which gets associated with the task and keeps it lingering in our minds. The completed problems are, well, complete, so we forget them and move on. They later called this the 'Zeigarnik effect,' and it has influenced the study of many things, from advertising campaigns to coping with the suicide of loved ones to dysphoric rumination of past conflicts.”
