Chapter 1 presents the main idea of the book, which is to give journalists the capacity to produce in-depth explanations of topical phenomena that are absent in the publicly shared knowledge. Analytical journalism is outlined as a particular discipline that enhances journalism's contribution to the public basis for deliberation with science-based causal explanations of current phenomena.

The discipline places the analytical journalist in a position of expertise and authority.
