Scott Alexander argues that despite some replication failures, the core of behavioral economics remains valid and valuable, with the field continuing to evolve and refine its understanding of human decision-making. Longer summary

Scott Alexander responds to Jason Hreha's article claiming the 'death of behavioral economics'. He argues that while some studies have failed to replicate, the core insights of behavioral economics remain valid. Scott examines the historical origins of loss aversion, discusses recent debates about its existence, and argues that even small effect sizes can be valuable at scale. He concludes that behavioral economics as a field is generally healthy, continuing to investigate and refine our understanding of human decision-making, though specific paradigms may evolve over time.

Scott Alexander critiques an NYT article on the weakness of financial incentives, arguing that they remain crucial as a counterweight to powerful social incentives. Longer summary

Scott Alexander responds to a New York Times article arguing that financial incentives are less powerful than commonly assumed. He agrees with the article's main points but offers four counterarguments: 1) Marginal cases matter more than average responses, 2) Social norms can be shaped by long-term economic incentives, 3) The principle can be applied inconsistently across political lines, and 4) Financial incentives serve as an important counterweight to social incentives. Scott emphasizes that while social incentives are indeed powerful, financial incentives play a crucial role in encouraging innovation and counterbalancing potentially stifling social pressures.

A study on expert prediction of behavioral economics experiments finds that experts have only a slight advantage over non-experts, suggesting that a separate 'rationality' skill may be more important than specific expertise. Longer summary

This post discusses a study by DellaVigna & Pope on expert prediction of behavioral economics experiments. The study found that knowledgeable academics had only a slight advantage over random individuals in predicting experimental results. Prestigious academics did not outperform less prestigious ones, and field of expertise did not matter. The expert advantage was small and easily overwhelmed by wisdom of crowds effects. The author suggests that these results indicate that experts' expertise may not be helping them much in this context, and proposes that a separate 'rationality' skill, somewhat predicted by high IQ and scientific training but not identical to either, might explain the results. The post also discusses the implications of these findings for real-world issues like election predictions, noting important caveats about the nature of the predictive task in the study.
