Scott Alexander explores five unspoken assumptions in discussions that can lead to misunderstandings and logical fallacies when not clarified. Longer summary

Scott Alexander discusses five unspoken ground assumptions in discussions that can lead to misunderstandings and logical fallacies. These include: (1) whether one is presenting a balanced view or arguing for one side, (2) if the argument is literal or pointing towards a hard-to-explain concept, (3) whether describing real-world phenomena or underlying mechanisms, (4) if addressing a specific problem or contributing to a broader intellectual discussion, and (5) whether presenting a definite theory or a hypothesis for consideration. He argues that ambiguity in these grounds can lead to confusion and false accusations of logical fallacies. Shorter summary
