Scott Alexander explores various commenters' insights on the neuroscience of reward, happiness, and relationships, expanding on his original post about unpredictable rewards. Longer summary

Scott Alexander discusses highlights from comments on his post 'Unpredictable Reward, Predictable Happiness', covering topics such as neuroscience of reward, dopamine, and relationships. He explores various perspectives on how the brain processes rewards, predictions, and happiness, including insights from neuroscientists, psychologists, and personal anecdotes. The post touches on topics like abusive relationships, polyamory, wealth and happiness, and the cognitive burden of poverty. Shorter summary

Scott examines two types of happiness - one affected by predictability and one that persists - through various examples and neuroscientific concepts. Longer summary

Scott Alexander explores the concept of happiness and reward in relation to neuroscience and prediction error. He discusses how there seem to be two types of happiness: one that is cancelled out by predictability (like the hedonic treadmill) and another that persists even when expected. The post delves into various examples including grief, romantic relationships, and drug tolerance to illustrate this pattern. Scott also touches on AI concepts and how they might relate to human reward systems. He concludes by suggesting that while unpredicted rewards can't be consistently obtained, predicted rewards can still be enjoyable. Shorter summary

This post highlights key comments on Scott Alexander's review of William MacAskill's book 'What We Owe The Future'. It covers various reactions and debates around topics like the repugnant conclusion in population ethics, longtermism, moral philosophy, AI risk, and the nature of happiness and suffering. Scott responds to several comments, clarifying his views on philosophy, moral reasoning, and the challenges of population ethics. Shorter summary

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

Scott Alexander examines the relationship between economic development, social changes, and happiness, concluding that happiness levels can change over time but are more influenced by intangible factors than by economic growth. Longer summary

Scott Alexander discusses the relationship between economic development, social changes, and happiness levels across different countries and groups. He explores Scott Sumner's question of whether anything matters for happiness, given that many countries show no increase in happiness despite significant improvements. Alexander examines data on African-Americans, women, and various countries, finding that happiness levels do change in response to social trends, even over decades. He notes that economic growth may increase happiness, but other factors like freedom and democracy seem more influential. The post concludes that happiness can change, but intangible factors are likely more important than money, even when lifting countries out of poverty. Shorter summary

Scott Alexander surveys people's preferences between suffering and oblivion, finding split opinions and weak correlations between different scenarios and real-world beliefs. Longer summary

Scott Alexander conducts a survey to explore people's preferences between suffering and oblivion in various scenarios. He presents five hypotheses and tests them using the survey results. The survey includes questions about preferring death over a difficult life, choosing between long unhappy life and short happy life, and population ethics. The results show that people are indeed split on these issues, with strong feelings on both sides. There are weak correlations between answers to different questions, suggesting a general factor of oblivion-preference versus suffering-preference. However, this factor does not strongly predict views on population ethics. The study finds weak correlations between oblivion preference and support for euthanasia, interest in cryonics, and personal happiness. Shorter summary

Scott Alexander examines the paradox of economic growth not increasing happiness in developing countries, questioning the moral implications for global development efforts. Longer summary

Scott Alexander discusses the paradox that economic growth in developing countries like China doesn't seem to increase happiness, despite lifting millions out of poverty. He explores the implications of this for utilitarianism and effective altruism, questioning whether efforts to boost national development are truly beneficial if they don't increase happiness. The post examines various explanations and potential responses to this dilemma, including abandoning consequentialism, redefining happiness, or focusing on preference utilitarianism. Ultimately, Scott expresses discomfort with all these options and acknowledges the perplexing nature of happiness research. Shorter summary

Scott Alexander argues that depression and suicide rates are not reliable indicators of societal well-being, critiquing simplistic interpretations of mental health statistics in social comparisons. Longer summary

Scott Alexander critiques articles that use higher depression and suicide rates in Scandinavian countries to argue against their social success. He points out that depression is not synonymous with sadness or social dysfunction, offering several potential explanations for higher rates in Scandinavia unrelated to societal well-being. He then demonstrates how depression and suicide rates don't always correlate with social dysfunction by comparing white and black Americans. Finally, he discusses a study showing that happier places tend to have higher suicide rates, challenging simplistic interpretations of mental health statistics in societal comparisons.
