The ideas that Duhigg and Mckibben have about social change are very similar. Duhigg believes that social change occurs through connections that people have, and how the connections work towards a main goal. Although Mckibben does not outwardly express this idea, it is shown that he thinks in a similar way through the movie “Do the Math”. Duhigg states “A movement starts because of the social habits of friendship and the strong ties between close acquaintances” (87). This shows that social change or a wide spread movement is started through the connections that people have in their life. Duhigg speaks about Rosa Parks as an example. The boycott of the bus system all started because Rosa Parks refused to give up her seat, but this was not the first time that a black person refused their seat to a white person. It had happened in the past, but the movement did not catch on because the person was not as known in all socioeconomic standpoints of the community in comparison to Rosa Parks. Parks was the frontrunner of the movement because she had those connections that spread into the boycott. Mckibben also has similar ideas. In the movie “Do the Math” he states “Today I know we’re going to fight the battle, the most fateful battle in human history is finally joined and we will fight it together” (14). It is not openly stated that connections lead to social change, but towards the end it is expressed that people need to come together in order to fix this problem. These quotes are discussing different things, but they both show that people need to come together either through connections or something else in order to lead to change. Both men do not necessarily agree 100%, but they both agree that people are needed as a group in order to change something in a drastic way.
