"We are systems that have been optimised to procreate as effectively as possible and to sustain their existence for millions of years. In this process, a large set of cognitive biases have been installed in our self-model. Our deepest cognitive bias is “existence bias”, which means that we will simply do almost anything to prolong our own existence. Sustaining one’s existence is the default goal in almost every case of uncertainty, even if it may violate rationality constraints, simply because it is a biological imperative that has been burned into our nervous systems over millennia."
