This review explores how schools are primarily designed to maximize motivation rather than learning, explaining why age-graded classrooms and seemingly inefficient group learning have persisted despite numerous attempts at reform. Longer summary

The post examines why schools have maintained their traditional structure of age-graded classrooms where all students learn the same content, despite its apparent inefficiencies. The author argues that schools are designed primarily to maximize motivation rather than learning, using conformity as a key tool. Through analyzing various attempts at personalized learning and their consistent failures to scale beyond about 5% of students, the post explains how students fall into three categories: no-structure learners, low-structure learners, and high-structure learners. The author concludes that while the current system is far from perfect, it has proven more effective at scale than any alternatives, predicting that despite continued attempts at reform, the basic structure of schooling will remain unchanged.

Scott Alexander explores new data on birth order effects among his blog readers, finding social factors likely explain firstborns' overrepresentation. Longer summary

Scott Alexander revisits the birth order effect he discovered in his blog readership in 2018, presenting new data from a 2020 survey. He confirms the original findings that firstborns are overrepresented among his readers, especially when age gaps between siblings are small. The post explores potential explanations, concluding that social factors, particularly parental attention, likely play a larger role than biological factors. This challenges some established views on the impact of early childhood experiences on adult outcomes. Scott acknowledges limitations in his analysis and calls for further research to better understand these effects. Shorter summary

Scott Alexander examines obscure pregnancy interventions that may improve child outcomes, rating them by evidence quality and potential impact. Longer summary

Scott Alexander reviews various obscure pregnancy interventions that could potentially improve child outcomes, particularly IQ. He rates them in tiers based on evidence strength and potential impact, with Tier 1 being most strongly supported. Key interventions discussed include embryo selection, choline supplementation, avoiding stress and certain substances, and optimizing birth timing. He emphasizes these are extreme measures not meant to induce guilt, and that standard pregnancy advice is still most important. Shorter summary

Scott Alexander follows up on his critique of a book about the Baumol effect, presenting data that challenges the book's claims about rising wages driving cost increases in education and healthcare. Longer summary

Scott Alexander follows up on his review of Tabarrok and Helland's book about the Baumol effect and rising costs in education and healthcare. He expresses disappointment with Tabarrok's response to his critique and further explores the issues. Scott presents data showing that wages in high-productivity sectors and for doctors and teachers have not risen as much as claimed, which challenges the book's central thesis. He also clarifies his understanding of how the Baumol effect can make things less affordable for individuals even if not for society as a whole. The post analyzes various data sources and graphs to support these points, maintaining a critical stance towards the original book's arguments. Shorter summary

Scott Alexander reviews a book attributing rising service costs to the Baumol effect, finding it convincing but raising some concerns about conflicting data and affordability issues. Longer summary

Scott Alexander reviews the book 'Why Are The Prices So D*mn High?' by economists Alex Tabarrok and Eric Helland, which attributes rising costs in services like healthcare and education to the Baumol effect. The authors argue that as productivity increases in some sectors, wages rise across all sectors, making labor-intensive services relatively more expensive. Scott finds their case convincing but raises some concerns, including data on stagnant real wages, conflicting information on professional salaries, and the apparent decrease in affordability of services like education, which the Baumol effect shouldn't cause. He seeks further clarification on these points to fully accept the Baumol effect as the primary explanation for cost disease. Shorter summary

Scott Alexander examines the history of increasing competitiveness in college admissions, analyzing causes and questioning whether the focus on elite college admission is justified. Longer summary

Scott Alexander explores the history of college admissions and the increasing competitiveness in recent years. He traces the evolution from a time when top colleges admitted almost anyone qualified to the current highly competitive landscape. The post examines various factors contributing to this change, including increased applications per student, changing demographics, and shifts in evaluation criteria. Scott also investigates whether the intense focus on college admissions is justified, given research suggesting that attending a selective college may not significantly impact most students' long-term outcomes.

Scott Alexander examines the phenomenon of cost disease, where costs for basic services like education and healthcare have increased dramatically without corresponding improvements in quality or wages. Longer summary

Scott Alexander explores the concept of cost disease, where costs for essential services like education, healthcare, and housing have increased significantly over the past few decades without corresponding improvements in quality or wages. He presents data showing how these costs have risen much faster than inflation, while worker salaries in these fields have remained stagnant or even declined. Alexander considers various potential explanations for this phenomenon, including market failures, increased regulation, lawsuit fears, and changing risk tolerance. He argues that this cost disease is a major factor behind many current political and economic debates, and expresses concern about its impact on living standards and economic progress.

Scott Alexander reviews research on teacher effectiveness, examining Value-Added Modeling (VAM) and its criticisms, while expressing uncertainty about claimed long-term impacts on adult earnings. Longer summary

Scott Alexander reviews research on teacher effectiveness, focusing on Value-Added Modeling (VAM) and its criticisms. He explores studies showing teachers account for about 10% of variance in student test scores, with effects decaying quickly over time. However, some controversial studies claim long-term impacts on adult earnings. Scott examines methodological issues, potential biases, and alternative explanations, ultimately expressing uncertainty about the validity of these long-term effects. He suggests non-cognitive factors like behavior might explain persistent impacts if they exist, but remains skeptical given the contrast with research showing minimal parental influence on outcomes.
