This research comes from John Gottman, a relationship expert based in Seattle, Washington. He obtained his data through the various normal methods of research, such as surveys and studies. However, one of the more innovative ways he discovered some of the statistics I've mentioned above was to invite couples into a Love Lab. This was a specific studio apartment, or rather a laboratory, at the University of Washington, where they would be monitored by video cameras, microphones and even sensors tracking bodily signs of stress or relaxation. The study was carried out over 16 years and is the most extensive and innovate research ever into marriage and divorce.
