Categories are not a useful way of demarcating sections in a document because they don’t support the structure of answering the key question of the document. For example ‘Background’ doesn’t say anything and the reader is forced to read through the section to connect the ideas rather than providing it to them. Section titles should answer the next question reader has from the preceding section to make it easier to understand your argument.

- Reading is the transformation of a linked list of ideas into a tree, without providing clear edges and nodes (like sections) the reader is left on their own to piece together the connections
