Write as a response to things that others say or might say. This helps to show that your writing is relevant to the field and readers see that your addition to the field is needed. What "they say" can be citations but also common or plausible beliefs. You do not need to just disagree, you can also agree with "them". In the end, it will be both: Building upon some things while rejecting others.
The book (see source) has specific chapters for different academic fields.
