Scott Alexander argues that the Dark Ages in Western Europe (500-1000 AD) did occur, presenting evidence of economic, demographic, and intellectual decline during this period. Longer summary

Scott Alexander argues against the claim that the Dark Ages never happened, presenting evidence for a significant decline in Western Europe from 500-1000 AD. He addresses common counterarguments, showing how they often rely on isolated demands for rigor or misunderstandings of the term. Scott provides data on economic decline, population decrease, and reduced intellectual output during this period. He acknowledges that the topic is complex and can be politicized, but ultimately concludes that the evidence supports the existence of a 'Dark Age' in Western Europe. Shorter summary

Scott Alexander uses NBA player heights as an analogy to discuss intelligence and IQ, advocating for a balanced view that acknowledges both innate talent and effort. Longer summary

Scott Alexander compares intelligence to height in basketball to demystify discussions about IQ. He analyzes NBA player height distribution, showing how extreme height gives a massive advantage. The post then draws parallels between height in basketball and intelligence, suggesting we should view intelligence similarly: as important but not solely determinative of success. Scott argues for a balanced view that acknowledges the role of innate talent while still valuing hard work and practice. He concludes by emphasizing the importance of cultivating high-level skills, including intelligence, to address future challenges. Shorter summary

Scott Alexander explores the concept of 'Eulering' and strategies for dealing with complex mathematical arguments in non-mathematical debates. Longer summary

Scott Alexander discusses the concept of 'Eulering,' where complex mathematical arguments are used to refute non-mathematical ideas, potentially leaving those less mathematically inclined unable to respond effectively. He uses the apocryphal story of Diderot and Euler to illustrate this concept. Scott explores the dilemma of whether to dismiss such arguments as sophistry or to accept them at face value, highlighting the trade-off between avoiding mathematical intimidation and maintaining intellectual rigor. He discusses his personal experiences with mathematical arguments in various fields, particularly focusing on statistics in scientific research. Scott proposes a strategy of 'routing around' complex mathematical objections by focusing on the underlying non-mathematical claims and evidence. Shorter summary

Scott Alexander discusses the Rationalist Solstice Ritual, exploring how 'cringeworthiness' can strengthen communities and the challenges atheists face in community-building. Longer summary

Scott Alexander reflects on the Rationalist Solstice Ritual, discussing its perceived 'cringeworthiness' and how this relates to community building. He argues that stronger religious communities often have more unusual or 'cringeworthy' beliefs, which create a stronger separation from out-groups. The post then explores how atheist communities struggle to build strong bonds due to lack of this separation, and speculates on various strategies atheists use to overcome this. Finally, Scott addresses the perceived lack of atheist art and music, arguing that many great secular songs about progress and humanism fill this role. Shorter summary
