Political knowledge isn’t just a matter of storing facts in a mental database. It involves understanding how those facts fit together, what patterns they reveal, and what explanations and predictions they support. In other words, political information must be interpreted to be comprehensible and actionable. Raw facts without organising principles, categories, and explanatory models are useless. Moreover, given society's vastness and complexity, these interpretive processes involve profound selection, prioritisation, and compression. A political worldview is inevitably a highly partial, coarse-grained model that collapses society into a handful of salient variables and dimensions, aggregates countless events into broad categories and indicators, and abstracts away from fine-grained details deemed irrelevant. The resulting idealisations determine what counts as salient, which high-level categories, causes, and forces matter, and what political actions to take.
