Nathan Franz @nathanfranz.bsky.social · 21/02/2026Something I realized today: "All models are wrong, but some are useful" applies in economics, but the usefulness is mainly rhetorical, not in describing reality. Models are engines of persuasion. 3120
Nathan Franz @nathanfranz.bsky.social · 21/02/2026A model is persuasive when its premises are ones the opposing side accepts, and its conclusions go against them. The rhetorical force comes from granting the other side's starting point. 140
