Scott Alexander discusses the concept of one-sided tradeoffs, using examples from college admissions to life hacks, and suggests ways to find opportunities for 'free' gains in various decisions. Longer summary

Scott Alexander explores the concept of one-sided tradeoffs using college admissions as a starting point. He explains how most decisions involve tradeoffs between different qualities, but suggests ways to find opportunities for 'free' gains. These include insider trading (having unique knowledge), bias compensation (exploiting others' biases), and comparative advantage (specializing in a specific area). He applies this framework to policy debates, life hacks, and personal decisions, arguing that understanding these concepts can help identify opportunities where one can gain benefits without significant downsides. The post concludes with examples like considering nootropics if one isn't afraid of taking drugs, or buying houses on streets with rude names for a discount. Shorter summary
