Having lived in the South in the past, I found the concept of "culture of honor" very interesting. Within the article by Cohen et al., (1996) not only does "culture of honor" shape the individual reaction, but affects the policies and laws of the region in the form of gun control, and self defense. In the movies, one sees the Southern gentlemen standing back to back, walking ten paces, and then shooting. Is this a relic of the past?
The research had different experiments under the umbrella of the study, and not all of the experiments showed statistical significance in the findings. They also stated a limitation of the research is that the research took place on a Northern college campus (Michigan) and all participants were from higher income bracket families. The Southern students had chosen to go to a Northern school. A confounding variable could be that these males did not adhere to the Southern perspective of having to be aggressive to protect one's honor, and were open to living in the North. It would be interesting to conduct the experiment in a Southern town setting, and possibly within the general population to test the reliability of the findings.
I personally did not experience co-workers coming to blows for bumping into one another in the hallway, but I also lived in a metro area that had a large mixture of Northerners. Possibly if I had lived in a rural area with a higher concentration of Southern men, we would have had a few good break time duels.
