    "Researchers find that being in a group makes some people lose touch with their personal moral beliefs. When people get together in groups, unusual things can happen -- both good and bad. Groups create important social institutions that an individual could not achieve alone, but there can be a darker side to such alliances: Belonging to a group makes people more likely to harm others outside the group.

    When people get together in groups, unusual things can happen -- both good and bad. Belonging to a group makes people more likely to harm others outside the group.

    "Although humans exhibit strong preferences for equity and moral prohibitions against harm in many contexts, people's priorities change when there is an 'us' and a 'them,'" says Rebecca Saxe, an associate professor of cognitive neuroscience at MIT. "A group of people will often engage in actions that are contrary to the private moral standards of each individual in that group, sweeping otherwise decent individuals into 'mobs' that commit looting, vandalism, even physical brutality."

    Several factors play into this transformation. When people are in a group, they feel more anonymous, and less likely to be caught doing something wrong. They may also feel a diminished sense of personal responsibility for collective actions.

    Saxe and colleagues recently studied a third factor that cognitive scientists believe may be involved in this group dynamic: the hypothesis that when people are in groups, they "lose touch" with their own morals and beliefs, and become more likely to do things that they would normally believe are wrong.

    In a study that recently went online in the journal NeuroImage, the researchers measured brain activity in a part of the brain involved in thinking about oneself. They found that in some people, this activity was reduced when the subjects participated in a competition as part of a group, compared with when they competed as individuals. Those people were more likely to harm their competitors than people who did not exhibit this decreased brain activity.

    "This process alone does not account for intergroup conflict: Groups also promote anonymity, diminish personal responsibility, and encourage reframing harmful actions as 'necessary for the greater good.' Still, these results suggest that at least in some cases, explicitly reflecting on one's own personal moral standards may help to attenuate the influence of 'mob mentality,'" says Mina Cikara, a former MIT postdoc and lead author of the NeuroImage paper.

    Group dynamics

    Cikara, who is now an assistant professor at Carnegie Mellon University, started this research project after experiencing the consequences of a "mob mentality": During a visit to Yankee Stadium, her husband was ceaselessly heckled by Yankees fans for wearing a Red Sox cap. "What I decided to do was take the hat from him, thinking I would be a lesser target by virtue of the fact that I was a woman," Cikara says. "I was so wrong. I have never been called names like that in my entire life."

    The harassment, which continued throughout the trip back to Manhattan, provoked a strong reaction in Cikara, who isn't even a Red Sox fan.

    "It was a really amazing experience because what I realized was I had gone from being an individual to being seen as a member of 'Red Sox Nation.' And the way that people responded to me, and the way I felt myself responding back, had changed, by virtue of this visual cue -- the baseball hat," she says. "Once you start feeling attacked on behalf of your group, however arbitrary, it changes your psychology."

    Cikara, then a third-year graduate student at Princeton University, started to investigate the neural mechanisms behind the group dynamics that produce bad behavior. In the new study, done at MIT, Cikara, Saxe (who is also an associate member of MIT's McGovern Institute for Brain Research), former Harvard University graduate student Anna Jenkins, and former MIT lab manager Nicholas Dufour focused on a part of the brain called the medial prefrontal cortex. When someone is reflecting on himself or herself, this part of the brain lights up in functional magnetic resonance imaging (fMRI) brain scans.

    A couple of weeks before the study participants came in for the experiment, the researchers surveyed each of them about their social-media habits, as well as their moral beliefs and behavior. This allowed the researchers to create individualized statements for each subject that were true for that person -- for example, "I have stolen food from shared refrigerators" or "I always apologize after bumping into someone."

    When the subjects arrived at the lab, their brains were scanned as they played a game once on their own and once as part of a team. The purpose of the game was to press a button if they saw a statement related to social media, such as "I have more than 600 Facebook friends."

    The subjects also saw their personalized moral statements mixed in with sentences about social media. Brain scans revealed that when subjects were playing for themselves, the medial prefrontal cortex lit up much more when they read moral statements about themselves than statements about others, consistent with previous findings. However, during the team competition, some people showed a much smaller difference in medial prefrontal cortex activation when they saw the moral statements about themselves compared to those about other people.

    Those people also turned out to be much more likely to harm members of the competing group during a task performed after the game. Each subject was asked to select photos that would appear with the published study, from a set of four photos apiece of two teammates and two members of the opposing team. The subjects with suppressed medial prefrontal cortex activity chose the least flattering photos of the opposing team members, but not of their own teammates.

    "This is a nice way of using neuroimaging to try to get insight into something that behaviorally has been really hard to explore," says David Rand, an assistant professor of psychology at Yale University who was not involved in the research. "It's been hard to get a direct handle on the extent to which people within a group are tapping into their own understanding of things versus the group's understanding."

    Getting lost

    The researchers also found that after the game, people with reduced medial prefrontal cortex activity had more difficulty remembering the moral statements they had heard during the game.

    "If you need to encode something with regard to the self and that ability is somehow undermined when you're competing with a group, then you should have poor memory associated with that reduction in medial prefrontal cortex signal, and that's exactly what we see," Cikara says.

    Cikara hopes to follow up on these findings to investigate what makes some people more likely to become "lost" in a group than others. She is also interested in studying whether people are slower to recognize themselves or pick themselves out of a photo lineup after being absorbed in a group activity."

    This seems to produce even more evidence for what is already a pretty concrete theory. Pretty cool stuff, thanks for sharing.

    One can see this effect in group discussions with alternate theorists, where a consensus mob forms, with some members getting nasty. The alternate theorists, who are on their own, for the most part, tend to be more respectful, until the mob goes after them.

    A mob can be considered analogous to a living entity, with the members of the mob, like cells of the entities body. The members of the mob distribute, as differentiated cells, so the mob creature can come to life. I would attribute this dynamics to the inner self and brain firmware. The inner selves of the group members, network to each other, and using this network assemble the individual firmware into the cells of the group entity. The network can empower some members to act as fist causing them to go way overboard, as individuals, but not for the needs of the mob entity.

    The discussion mob is an interesting entity because there is separation in time and space between the cells of the entity. This mob forms, spread over space and even time using people from different part of the world. This is different from the normal demonstration mob, where the sensory systems are used to directly connect the cells within the same place in time and space.

    There are usually a few instigators that mixed in with any crows to both create a problem then capitalize on that problem by robbing stores and hurting others. If the crowd would just get rid of those who are disrupting the gathering there wouldn't be any disruptions but alas that doesn't happen.
