There are two main elements to sanity: having a rational and sound interpretation of reality, and acting in a way which rationally benefit's ones interests. I think hypersanity would constitute not only a hyper-rational worldview, and to reconcile common cognitive dissonance, but also the ability to integrate that awareness into better self-preserving behaviour (to improve ones safety or efficacy), rather than to respond with depression, terror, self-ostracism, etc.
