Sociologists have long argued that explanation, as a form of knowledge, has serious limitations when it comes to understanding society. The case against explanation is one of the field's founding ideas, it is literally a foundational idea. It was by rejecting causalist forms of explanation that had been developed in the natural sciences that 19th century scholars and activists that we today call sociologists succeeded in articulating a distinctive realm of reality with relative autonomy from the state, the economy and the family: society (Wagner, 2000). Key to their achievement was the argument that the phenomenon of society is fundamentally different from nature. Scientists at the time expected nature to obey eternally valid laws, but society has a number of features that challenge this assumption.Social actors formulate norms and rules to justify their actions and to make sense of social reality. This means that norms and rules themselves may play an active role in the transformation of social reality. Society, in other words, is marked by reflexivity. Of course, a lot has happened since the 19th century and this very notably includes unrelenting efforts by social scientists to create forms of explanation that are capable of taking reflexivity into account.Yet problems with explanation have continued to make themselves felt in the social sciences and humanities. The problem, in a nutshell, is that explanation sets up the relation between social science and its object, society, in terms of representation, but the relation between knowledge about society and social reality is fundamentally an interactive one: the creation of knowledge about society far more often than not involves intervention in society.The creation of social scientific knowledge can rarely, if ever, by considered a purely representational affair. This obtains for practically all forms of knowledge about society -and as we shall see, about nature as well -but it causes specific problems for the explanation of social phenomena. Let me give an example from contemporary social science, broadly defined. Some years ago computational social scientists published research that showed that the high levels of political polarization that can be observed among communities on Facebook cannot be explained by the This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.
