When it comes to thought and research on social movements and technology (separately and together), emotion is that crucial piece of the picture that everyone technically sees but hardly anyone explicitly acknowledges as worth paying attention to in its own right. Some of this is likely because emotion is hard to study in any way that social science would consider rigorous; it’s often taken as something fundamentally irrational and therefore fundamentally inexplicable. It is highly subjective. It is culturally and situationally constructed, and therefore conceptually slippery. It is interior; it is a difficult thing to see and to know. If explicitly drawing it out as an important factor is problematic for some, identifying it as a variable capable of carrying any causal weight is even more so.
Regarding technology and social movements combined, there is the question of how the digital and physical play out as far as what ends up really being important. What is the relationship between the two? Where exactly is the body in augmented contention and is the way in which it matters changing? What is really going on when we see a bunch of street protesters carrying smartphones?
