Duhigg uses “voice markers” in his writing and they distinguish the different perspectives throughout his essay. Duhigg refers to the relationship we have with close friends as “strong ties”. I agree that the relationships you have with close friends are considered “strong ties” because they know you better and are closer so they should have a stronger tie to you than acquaintances. I agree with Duhigg’s statement “Such peer pressure, on its own, isn’t enough to sustain a movement.” I agree with this because the peer pressure provided isn’t enough for more than a few people to do something about the problem. To sustain a movement you need more people than what the peer pressure provided. When Duhigg mentions having more “weak ties” is more beneficial than having a “strong tie” I did not agree because I thought people who were closer to you would be more willing to help. As Duhigg explained further my opinion changed and I now agree that having more “weak ties” is more beneficial.
