Some questions I had while reading this article (have not read the paper) 1. Is the number actual number of people in a population or percieved number of people? That is, can someone generate fake social media accounts, inject a belief, and make it seem as if something reaches the tipping point? 2. Does this tipping point vary by culture? For example, when I read about American techies working in Japan, they speak about the excessive meetings, and consensus making that happens in companies. Do social changes require more people? Or is it that, that tipping point remains about the same, yet fewer people are likely to voice something in the first place? 3. What happens when you have multiple activist groups who are each above the tipping point, each advocating for some change?
