Scott Alexander examines the use of absurdity arguments, reflecting on his critique of Neom and offering strategies to balance absurdity heuristics with careful reasoning. Longer summary

Scott Alexander reflects on his previous post mocking the Neom project, considering whether his use of the absurdity heuristic was justified. He explores the challenges of relying on absurdity arguments, acknowledging that everything ultimately bottoms out in such arguments. The post discusses when it's appropriate to use absurdity heuristics in communication and personal reasoning, and offers strategies for avoiding absurdity bias. These include calibration training, social epistemology, occasional deep dives into fact-checking, and examining why beliefs come to our attention. Scott concludes that while there's no perfect solution, these approaches can help balance the use of absurdity arguments with more rigorous thinking. Shorter summary

Scott Alexander explores the overuse of the term 'conspiracy theory' and provides heuristics for evaluating the plausibility of conspiratorial claims. Longer summary

Scott Alexander discusses the concept of conspiracy theories, arguing that the term is often overused and misapplied. He presents a list of various claims, ranging from political conspiracies to scientific misconduct, and analyzes which should be considered conspiracy theories. The post introduces the 'Basic Argument Against Conspiracy Theories' which states that large secret organizations are difficult to maintain without detection. Scott then applies this principle to various scenarios, showing how some seemingly conspiratorial ideas might not actually qualify as conspiracy theories. He concludes by offering heuristics for evaluating the plausibility of conspiracy claims, emphasizing that the size, secrecy, and self-interest of the groups involved are key factors to consider.
