Evolution of Natural Selection Challenges Perception of Reality

Donald Hoffman, cognitive scientist, questions the accuracy of human perception, stating that what we see is a construct of adaptive behavior rather than an accurate representation of reality. He explains that while our perceptions guide our behavior, they do not necessarily reflect objective truth. Hoffman argues that evolution by natural selection does not maximize for truth, but rather for survival and reproductive success. He suggests that our understanding of reality is limited by our perceptual interface and that we must go beyond space-time to uncover a deeper understanding of the nature of reality.
