Ingroup bias - To illustrate how easily and quickly we form ingroups and outgroups, I divide my class into those wearing tennis shoes that day and those not wearing tennis shoes. Then I have each group sit in a circle with its members. The "tennis shoe" group is assigned to list as many reasons as it can think of as to why the members of the other group did not wear tennis shoes that day. The non-tennis shoe group is assigned to list as many reasons as it can as to why the other group members are wearing tennis shoes. The listing starts out fairly neutral, but it is not long before each group's list becomes more and more derogatory, particularly when it overhears the list the other group is generating.

  "The roots of polarization" (19:28) - The link is to a podcast on the topic from Dominic Packer and subscriber Jay Van Bavel. Here is a link to the follow-up podcast on some solutions to polarization.

  "From activism to radicalization: The tipping point of unfairness" (19:28) - From APS, this podcast is a companion piece to the APS President's final column, "The societal divide: What can we do about it?" linked above. Conflicts driven by nationalism, ideologies, and cultures have become all too common.  What can psychological science tell us about the causes and mental processes that push people from activism to radicalization?

Longing for the "good old days" (24:47) - This podcast includes a discussion with Michael Wohl regarding recent research published in Current Directions. "As the United States prepares for its next election, this research provides intriguing insights into how political rhetoric tends to capitalize on the relation between these emotions by promising to “bring back the good old days.”  Here is a link to a report of research that is related.

Projects

Building Cross-Cultural Understanding Through Facebook - This project also won honorable mention for the 2013 Social Psychology Network Action Teaching Award. "This assignment uses social media to give students a chance to have meaningful cross-cultural interactions while learning about social psychology and ways to promote international dialogue, peace, and social justice. In this particular case, a Facebook page was co-developed by psychology classes in Egypt and the United States, and student groups in each class were asked to design a program that would improve relationships between Muslims and non-Muslim Westerners by using what they had learned about (1) the causes of prejudice and intergroup conflict, and (2) methods for reducing prejudice and making peace. After students designed their programs, they discussed them in class and then posted their ideas to the Facebook page for comments by students from the other country. As a result of this cross-cultural exchange, students often reported that they had not only learned about psychology of prejudice reduction but that their own prejudices had been reduced. As one student summed up the experience in her final Facebook post: 'thank you all for teaching so much in such a short period of time! I learned a lot about you and about myself from this project, and I know that the lessons I learned will stay with me for the rest of my life.'" [added 8/9/13]

Using Lessons from the Holocaust to Reduce Bullying - The final honorable mention from the 2007 Action Teaching Award was given to Ruth T. Hannon for her creative assignment in her Perspectives of the Holocaust course. From the proposal: "Over the next several class sessions, our college students meet in small groups to design projects to be taken to the middle school. Their task is to use lessons from the Holocaust to teach about the dynamics of prejudice, hate speech, and bullying close to home. For example, our students have spoken about the psychology of conformity and depicted how conformity operates in bullying situations. Middle school students come to see the power of conformity in such situations, and they learn ways to resist being drawn into bullying behaviors. Lively discussions follow and, oftentimes, middle schoolers share stories about bullying they've witnessed." [added 7/7/07]

Retail work
Through working at Macy's [a department store], I have learned that niceness does not always lead you to the best outcome for every situation. Every time we clock into work, we have a sales goal that we have to obtain by the time our shift is over. Because of this, if we are working with someone else we are faced with the dilemma of amicably working together with the coworker or to compete with them in order to more surely meet our sales goal. In the past, I have always been used to fully cooperating with my coworkers in order to get the job done more effectively. Not until I have been thrown into the shark tank that is the retail workplace that have I been faced with the idea that I must make sure that one person doesn't take all of the department's sales away from me while I am working on something else away from the register. In order to get around this large barrier between us and to establish understanding that both of us need to meet a certain goal, I always ask how the other person is doing for the day and how much more money he or she needs to bring in. By doing this, I make the person aware of how he/she needs to either pick up the pace or slow down and allow me a chance to ring some transactions. This way, I can stay competitive with my sales intake while remaining friendly and cooperative with the person that I am working with. Another way to keep the balance of competition and cooperation in the department is to ask each customer if anyone else has been assisting or working with them to make their visit more enjoyable. If the customer says that they really did not need help so no one assisted them, then I can ring them up without hesitation. However, if someone has been helping them, then it is only fair to let the person helping them ring them up because they were the ones who earned the money from the transaction. With this, a lot of trust is built up between people in the store, trust that other people will pull their own slack and trust that they will only build their sales goal with the customers that they have helped or with the customers that had no significant assistance from any other coworker. [added 12/17/12]

Using incentives for cooperation or conciliation - "Rice, in Nairobi, offers incentives to end violence." [added 4/11/08]

Promoting Arab and Israeli cooperation - interesting example of "peacebuilding through health initiatives"

Cooperation and competition are very important in a job related atmosphere. Cooperation is something a small group within the office I work in is in need of. This group has five girls in it which are all competitive. The team effort belief in this part of our company is diminishing. The problem seems to be that the girls are afraid to cooperate because they won't get the credit or be recognized individually for their effort or ideas. Some social loafing is taking place. They are so eager to do well and improve that they tend to do their jobs ignoring all factors around their areas except their own. They are afraid to communicate or trust because someone might steal their idea or rework it. In addition, the males in our office tend to cooperate more than the females. I believe that females feel they must be more competitive to be noticed in our office. However, this competitiveness, lack of trust and communication is hurting their cooperation levels. Many times the girls refuse to talk and just clam up with one another. This creates gates or blocks in good working habits and therefore poor performance. In addition, this attitude expands and turns into threats like "Well, I'm just not going to do it" or "It's not my job." Unfortunately, these threats reduce the chance of cooperation. However, I believe the girls are basically competitive and there is no hatred as an outsider might think just by hearing or observing this situation. In addition, I believe this problem is going to be tackled soon. A meeting is going to take place on Tuesday of next week for these five girls. Finally, this mess was brought to a manager's attention (his eyes are usually closed to problems until they're overwhelming -- yet, another problem area). He realized that there are some problems and that most of all the competition within this group has brought about hostility. He is going to bring them together (the meeting) which is one good starting approach to get these girls back on track. I'm sure he is going to then force them to cooperate or else. I'm sure it will work.

Sources of Conflict

Superordinate goal and ingroup/outgroup - This blog entry discusses the U.S.'s current debates over refugees and Muslims.

Ingroup bias - When I was in Grammar School, it was the biggest deal to be part of the popular group; that’s all I ever wanted. Finally, after years of trying I made it in this distinctive group. This is the perfect example for the Ingroup/Outgroup. In order to be in our group, which by the way we called ourselves the “perfect 10” because there were ten of us, you had to be and act a certain way. Your hair had to be done a certain way, it had to be a certain color, and on various days we all planned to wear matching items. One particular day I remember was a Friday, we called it “crazy pants day.” We all had to wear tight animal print pants and a black top. Everyone wanted to be a part of this group. If you weren’t in it, we were making fun of you, whether it was how you looked, who you hung out with, or just for who you were. We were awful little girls. I remember one day, the day we wore the crazy pants, a few teachers overheard what we were planning and planned to wear matching outfits that same Friday. It’s quite odd looking back and realizing just how big of an impact we had even on adults. By no means am I saying this was a good thing. There are many days where I wish I could take it all back. Why do we have to have these groups, that make others just feel terrible? What was it that gave this group I was in all the power? Even though I was a very mean little girl, I believe if I hadn’t have had experiences like this I wouldn’t be who I am today. Finally I left the “Perfect 10” because I couldn’t take making fun of others for no apparent reason, and now I don’t really judge anybody without getting to know them. [added 4/16/08]

The power of symbols - Here's an interesting story of a couple in Colorado who have been threatened with a fine by the homeowners association if they do not take down their Christmas wreath shaped like a peace sign "that some say is an anti-Iraq protest or a symbol of Satan." [12/27/06]

Tragedy of the Commons, use of norms, fear appeals, and more - David Myers shares this example from Cape Town’s severe water shortage and its efforts to encourage citizens to conserve.

Prisoner's Dilemma

Prisoner’s dilemma

Prisoner's Dilemma - David Myers pointed me to this game show which apparently forces contestants into a sort of prisoner's dilemma at the end of each game, with communication permitted. See the very interesting strategy this particular contestant uses. [added 6/20/12]

Over the months since my daughter started back to school, I've been experiencing a mini-Prisoner's Dilemma. Every month the school sends home a notice pleading for volunteers for the Picture-Parent Program. (Once a month a parent would show a print by a famous artist to the class, giving details about the work of art, the artist, etc.) Every month I have been selfish and ignored the requests, hoping that someone else's parent will volunteer. (Partly I have ignored the requests because I truly don't have time since I'm enrolled full time at NCC. Partly I've ignored the requests because of a stereotype that I have about the typical suburban housewife -- lots of free time to fritter away here and there on nonessentials.) They have more time than I do; therefore, let them do it. Well, evidently, they are being selfish also because yesterday a final notice came home from school. My daughter's class still does not have a volunteer. Unless someone responds this week, her class will miss out on this "valuable learning experience." Thus comes the Prisoner's Dilemma. If I continue to be "selfish," it's the best thing for me but bad for my daughter's class. If I don't ignore it and the other's don't ignore it, then that's best for the school but not for me. If we all ignore it (which we have so far) it's bad for the school but better for me than if I don't ignore it but the others do. They will be following their most selfish strategy and I will be mad. So far we have both been following our most dominant strategy -- ignore the notice. What to do now?! Another reason I have for not wanting to volunteer is that I fear they will use the foot-in-the-door technique. They'll start off with just being a Picture-Parent. It only takes one hour per month and you care about your child's education, don't you? Then once they've got you at the school, they start lowering the boom with project after project that needs your help. You start off slowly just helping out and before you know it; somehow, you're the chairperson of the committee running the project yourself. My initial commitment to the school would cause me to be consistent. I know it's all happened before.

Blacktop Illusion

When reading about the blacktop illusion I couldn't help but think about the Bears and Packers. After the initial emotions died down when Charles Martin body slammed Jim McMahon a couple years ago, most people, and especially the Bear players, felt the whole incident was the Green Bay coach's fault. Everyone was blaming Forrest Gregg for instilling evil in the hearts of his players and teaching them to play dirty. The Bears must have felt the players were just normal people like themselves so the Green Bay players must have been mislead by the coaching staff.

Younger vs. older workers - Interesting studies: "The population of most developed societies is 'graying'. As life expectancy increases and the large baby-boom generation approaches retirement age, this has critical consequences for maintaining a high standard of living and the sustainability of pension systems. In the light of these labor-force and social concerns, we consider experimentally the comparative behavior of juniors (under 30) and seniors (over 50) in both experiments conducted onsite with the employees of two large firms and in a conventional laboratory environment with students and retirees. Our results are compelling. First, seniors are not more risk-averse, as opposed to the conventional stereotype. Second, both juniors and seniors react to the competitiveness of the environment and there is no significant difference in performance in the real-effort task across the generations when they are competing. Third, seniors are typically more cooperative than juniors in a team-production game. Cooperation is highest in groups in which there is a mix of juniors and seniors, suggesting that there are indeed benefits in maintaining a work force with diversity in age." [added 7/7/07]

Peacemaking / Reducing Conflict

"How group-oriented leaders can drive success and collaboration"

"4 in 5 Americans would put aside differences for common causes" -- At least that's what the survey says. I want to see the studies that directly test that. Ask your students how they would test whether people actually would.

"How do we make society less polarized?" -- This blog entry discusses some research that tries a novel approach -- trying to get people to reclassify the way they look at something. The study used the contents of a refrigerator, and asked participants to classify the fridge as a Biden or a Trump fridge.

"What can bridge political divides?" -- "What a political opponent would have to say to increase your respect for them." We found that 56% of participants believed facts and statistics would drive respect, while only 21% believed experience sharing would. However, this intuition is wrong. While we all believe facts are truth, in reality, personal experiences are seen as both more undeniable and more true-making personal experiences powerful in bridging political and moral divides."

Meet a Jew program -- "The Central Council of Jews in Germany has launched a program called 'Meet a Jew' in the hopes that if Germans actually met a real, live Jewish person, perhaps it could be a start in addressing the burgeoning antisemitism in the country."

"The myth of tribalism" - Interesting essay -- tribalism does not have to be a bad thing.

"The societal divide: What can we do about it?" - This essay is the final column from APS President Shinobu Kitayama.

"Training to wisely navigate social conficts"

Can a sense of fairness overcome political differences? - interesting research

Conflict resolution - The APS provides a series of articles on the topic.

“More unites us than divides us” - A new study suggests that diverse groups around the world share more in common in terms of their beliefs and values than polarised reporting too often suggests.”

"Anger derails negotiations, unless you have a plan"

"The seven habits of highly depolarizing people" - Here are some very good suggestions for persuading or working with those who are quite polarized in their views.  I was going to say "provide alternate facts," but this is probably better advice.

Is cooperation more likely after more or less deliberation? - Research says... "making decisions based on intuition significantly increased rates of cooperation, but only under circumstances where self-interest was always the best option.  When people had time to has out all the details in these situations, they were far less cooperative."

"Six elements to make your apology optimal"

Reducing conflict through intergroup contact - recent research conducted in the field

The power of intergroup contact - Another, recent meta-analysis of intergroup contact research again found it can be quite effective in reducing such conflict.

When to make the first offer - "A subsequent analysis of the negotiations conducted between those who were diametrically opposed clearly showed that the negotiator who made the opening offer, on average, benefitted to the tune of $5.60 million more than his opponent. A clear First-Mover Advantage. However the opposite was the case for the negotiation parties who shared compatible views. In these situations the party making the opening offer ended up with significantly less value. What the authors coined a First Mover Disadvantage." [added 3/2/15]

Does gossip promote cooperation? - Research suggests that the threat of ostracism behind some gossip discourages self-interest and encourages cooperation. [added 2/18/14]

Building cooperation among rivals - an essay from subscriber Steve Martin at the Influence at Work site [added 2/18/14]

Rebuilding a burned-out Mosque - This columnist argues that "helping a burned-to-the-ground Missouri mosque quickly re-build would make a powerful and constructive statement." [added 12/19/12]

The handshake as contract - [added 5/30/11]

Negotiation over computers: Distance matters - "Negotiations that take place over computer, without face-to-face contact, have more chance of success when those negotiating think there is greater physical distance between each other. That's according to Marlone Henderson who says the new finding is compatible with Construal Level Theory. This is the discovery that people think about things more abstractly when they perceive that they're further away in time or space (e.g. see earlier). In terms of negotiations, thinking more abstractly is beneficial because it encourages negotiators to reflect on and express their underlying motives and priorities." [added 5/30/11]

Egyptian Muslims protect Coptic Christians - [added 5/30/11]


The Institute for Strategic Dialogue - another think-tank producing reports and research on international conflict [added 12/18/10]

Good publications and other resources here. [added 7/17/09]

"Does going to Mecca make Muslims more moderate?" - First, nice alliteration in that headline! Second, I like when naturally occurring random assignment makes such studies possible. [4/17/09]

"Why things cost $19.95" - another interesting recap of research from Wray Herbert's APS blog "We're only human" [added 4/5/08]

Violence in Kenya - The first link is to a news story about the violence in Kenya. Here is a link to an analysis, "Breaking the stalemate in Kenya," which explores how the crisis evolved and how it might be resolved. [added 4/5/08]

[added 9/20/05]

U.S. Institute of Peace - reports and other resources [added 3/20/05]

"The counterterror coalitions: Cooperation with Pakistan and India" - From the Rand Corporation, "the study examines U.S. strategic relations with India and Pakistan both historically and in the current context of the global war on terrorism. An inescapable conclusion of the report is that the intractable dispute over the disposition of Kashmir remains a critical flashpoint between India and Pakistan and a continual security challenge. The author offers five policy options on how the United States might proceed." [added 3/20/05]
