The post explores how correlated variables can diverge at extreme values, applying this concept to happiness measures and moral systems. Longer summary

This post explores the concept of 'tails coming apart' and its application to various domains, particularly morality. The author begins by discussing how strongly correlated variables can diverge at extreme values, using examples like grip strength vs. arm strength. He then applies this concept to happiness, showing how different measures of happiness (e.g., life satisfaction, positive emotions) can lead to different countries being ranked as 'happiest'. The post extends this idea to morality, arguing that while different moral systems may agree in everyday situations, they diverge dramatically when taken to extremes. The author suggests that this divergence poses challenges for developing moral systems that can handle transhuman scenarios. Shorter summary
