Scott Alexander argues that non-empirical reasoning, based on principles like simplicity and elegance, is a necessary and legitimate part of scientific practice, even for evaluating seemingly untestable theories. Longer summary

Scott Alexander discusses the role of non-empirical arguments in science, challenging the view that untestable theories are inherently unscientific. He argues that even in cases where direct empirical testing is impossible, scientists use principles like simplicity and elegance (often formalized as Occam's Razor) to evaluate competing theories. Scott uses examples ranging from paleontology vs. creationism to multiverse theories in physics to demonstrate that this type of reasoning is both necessary and legitimate in scientific practice. He concludes that while there may be debates about the best way to formalize or apply these principles, it's crucial to recognize that some form of non-empirical reasoning is an inescapable part of the scientific process.

Scott Alexander examines and critiques the claim that good-vs-evil narratives in popular culture are a recent, nationalism-driven phenomenon, offering alternative explanations for their prevalence. Longer summary

He draws parallels between the spread of Christianity and the popularity of good-vs-evil narratives, suggesting that both offer a more appealing worldview than their predecessors. The post ends by speculating on the future evolution of such narratives. Shorter summary
