What's Your Definition of the Partisan Mind?

i want to get at the partisan mind from the question of its origins, like, where does this partisan mind come from? And there are at least two explanatory narratives that i think are compatible. As a christian, my perspective is thouh though that is compatible with the biblical theological narrative. I think we can, as christians, sort of conceive of god as creator, and also of the biblical narrative of things like the fall. The social psychologist would say that what's going on in the partisan mind is that there's our huge emotional, subconscious drivers in the human mind which drive the partisan mind.
