Gazzaniga blamed this behavior on “the interpreter” module, located somewhere in the left hemisphere. The basic idea is that the brain is constantly trying to weave a narrative out of the cacophony of reality - it’s desperate to make sense of the world. Interestingly, much of this narrative is written in reverse, as we brazenly re-write what just happened. We conveniently forget that we didn’t choose that attractive face, or that the shovel has nothing to do with the chicken shed. The ridiculous contradiction isn’t suppressed - it’s not even noticed. We end up happily justifying choices we didn’t make.
