Charles Duhigg and Helen Epstein talk about creating Social Cohesion but in two different ways.  Helen Epstein is a well noted journalist and she traveled to South Africa and Uganda discovering ways to prevent the AIDS Epidemic. In an excerpt from AIDS Inc. Epstein stated, “I spoke to the principal first, and he showed me the government-issued manual used for teaching about AIDS, which contained the usual information about abstinence and condoms”(118). This meaning that there is a government mandated manual that the students have to know or at least talk about in class so they obtain knowledge of AIDS, HIV, safe sex, and abstinence. Teaching the young generations will benefit the future because it will prepare them to teach the other generations after them. If all of the other communities and governments required a manual such as the one mandated in Kigali there can be social change and the communities can come together as one to help better all communities in Rwanda and eventually Africa. On the other hand, Charles Duhigg creates Social Cohesion in a completely different style. In the excerpt from his novel, The Power of Habit,  Duhigg refers to Mark Granovetter. Mark Granovetter was a Harvard Ph. D student that explained job hunters and the relationship we have with people.  Granovetter said, “While members of one or two cliques may be efficiently recruited, the problem is that, without weak ties, any momentum generated in this way does not spread beyond the clique. As a result, most of the population will be untouched”(91). Granovetter is stating that with our close friends and relationships one can only gather so much before, hypothetically, they run out of bodies for a rally. Without the “weak ties” people have with each other there would not have been huge rallies throughout history, especially not during the Civil Rights movements. Each explains a way Social Cohesion is used to make a change. Epstein is explaining how the use of a governement-issued manuals about AIDS helps the community. Granovetter explains how weak ties result in social movements creating Social Cohesion.
