How Many Topics Should We Look For?
Compare what the model finds when you change how many topics it looks for. The main model uses 30 topics. Here you can switch between 5, 15, and 30 topics - same data, same method - and see which topics survive and which disappear. Shared topics are shown in colour; topics that only exist in one version are shown in grey.

What This Means
Core Finding
Only 6% of topics survive when moving from 30 to 5. At low resolution, seven distinct policy areas collapse into one group. Specialist voices disappear entirely — they only become visible when the model looks for more topics.
Core Insight
The number of topics acts like a zoom control. Only two topics survived every test — everything else changed depending on the settings. Lower resolution systematically silences minority voices.
