Politics and business are incredibly complicated as well. In many ways it’s even harder to do reporting in those areas because there is no expert consensus you can consult. Is lowering corporate taxes better for the economy? There is little consensus. Even reporting “what people did” can be fraught with peril. (E.g. reporting that a company “paid no taxes” without addressing loss carry forwards.) Political and business systems, and in particular complex regulatory regimes like tax policy, are the product of many decades of refinement. Because journalists for the most part are ignorant of that history, they present every policy issue in this sort of context free way, leaning heavily on narrative and emotion to make up for their shallow understanding of the actual mechanics of what they’re writing about.

I think where the comparison breaks down is that the laws of physics are the laws of physics. Reporting on them doesn't change them. But politics lives in the same world as reporting. It is shaped by it, politicians respond to it. So the Gell-Mann effect isn't quite accurate in that situation. Journalists do know the political world deeply because for better or worse they're involved in shaping it.

I don't think it follows that people must necessarily know a lot about things they have a relatively large influence over.
