Economics is one of the scientific sore spots for liberal ideology. If you are liberal and mostly swim in liberal circles, you probably believe that economics is mostly bunk pseudoscience. Akin to conservatives and climate change

To be fair, macroeconomics can hardly be called science, though. It is incredibly hard to falsify a lot of the theories given the lack of possibilities for experimentation. It is far closer to philosophy than to any of the even remotely hard sciences.

Nothing to do with ideology, but with the nature of the field. Take epidemiological research in the areas of food and medicine: incredibly hard and expensive to get right and even then with often tenuous results. Now try doing that with ridiculously heterogeneous nations influenced by potentially almost everything on the planet.

It's a small miracle that economists manage to get some useful insights out of the data, but we should definitely be aware of how weakly most of them are supported (don't start talking about "error bars" with economists).

In fact that there's both a liberal and conservative economics ideology, and what could form a scientific discipline in between is unfortunately cornered and sorely lacking visibility.
