Here are some notes, and attached is the mark scheme to help get the highest mark. And here is the link to a good guide : https://www.ibmastery.com/blog/how-to-structure-a-theory-of-knowledge-essay (P.S. The title is not allowed to change). What do we mean by ‘Robust’ ? Is an agreement to disagree actually a form of consensus ? One way of looking at this essay is to go into the process of knowledge production. You would need to find cases of knowledge production which required both consensus & disagreement in order to reach a ‘robust’ conclusion. In counterargument you would need to find examples of knowledge production which were either mainly consensual (or came out of falsification), or examples of consensus and disagreement which led to weak (‘not robust’) knowledge. The essay partly hinges around the definition of the word robust.
