The article explores the philosophical divide between concave and convex thinking, particularly in decision-making. Concave thinkers seek balance and moderation, believing that extremes often lead to negative outcomes. They argue for a middle ground, where both positive and negative aspects of opposing philosophies can be considered. For example, in debates over Bitcoin block size, the author favors compromise over strict adherence to either small or large blocks. The Ethereum ecosystem exemplifies this concave mindset, while Bitcoin tends to lean towards a more rigid, convex perspective, where issues are treated as binary choices. Convex thinkers, on the other hand, advocate for a more focused approach. They argue that compromise leads to mediocrity, insisting that sticking to a single philosophy is essential. The author cites examples like the response to the coronavirus pandemic, where half-hearted measures can lead to greater issues than taking a firm stance. The article highlights the dangers of middle-ground approaches in contexts like war or public health, where a decisive strategy often yields better results than divided efforts. The author also discusses economic principles, particularly the inefficiencies caused by tax rates. A low tax rate might deter few transactions, while a high rate could deter valuable ones, leading to quadratic harms. Finding a balance in taxation can maximize revenue and efficiency, similar to the dynamics of the Laffer curve. This principle extends beyond taxes, as the author points out that many everyday behaviors and economic activities exhibit diminishing returns, reinforcing the value of a balanced approach over extremes.
