In this mindset, we see the essence of the psychitect. Most people strive to preserve their beliefs at all costs - to protect them from the constant threats that seek to undermine them. But if you are a psychitect, all beliefs are really just temporary experiments. Every day is a mental beta test - an opportunity to iterate, expand, and upgrade your cognitive software. To uncover and question assumptions, test new conceptual models, and throw the obsolete ones out. No belief is safe.
