There is this ideology that disagreeableness is the forcing function that underpins all human innovation. But this is just not the case. The cause of consensus divergence is the manipulation of language for the betterment of self at scale. We evolved language before it became a post Dunbar problem. Disagreeableness is senseless disagreement for the sake of disagreement to self validate. It is a power acquisition strategy. You claim individual intelligence when it does not exist and use that to justify polar acquisition of resources.
