I’d argue we all have an ideology, it’s the way we interpret the world around us and construct a coherent narrative. I see ideology as a world model that we construct. I think the difference is that some of us go through this process consciously while others aren’t aware of it. Those of us who are conscious of the fact that we have a model of the world, are able to test whether the model aligns with what’s actually happening in the world and updating our world views as necessary.
