Scott Alexander explores 'bicameral reasoning', comparing how we often weigh issues equally (like the US Senate) instead of proportionally to their importance (like the House), leading to potentially skewed decision-making. Longer summary

This post discusses the concept of 'bicameral reasoning', drawing parallels between the US House and Senate representation systems and how people make decisions or judgments. Scott Alexander argues that often we give equal weight to issues of vastly different importance, much like how the Senate gives equal representation to states regardless of population. He illustrates this with examples from political issues, animal welfare considerations, and environmental concerns. The post suggests that this 'Senate-like' thinking can lead to poor decision-making by equating minor issues with major ones. While acknowledging some potential benefits to this way of thinking in extreme cases, the author ultimately argues for a more proportional 'House-like' approach to evaluating issues based on their actual impact or importance.
