I've had an archive of crop formation diagrams sitting around for a while — 31 annual collections covering 1990 to 2020, 3,382 formations in total. I finally ran a proper analysis on it and I'm sharing everything. How it was done I wrote down every hypothesis and its pass/fail threshold before running any test, so I couldn't move the goalposts once I saw results. Every test is logged — 148 of them — including the ones that found nothing. Each positive claim had to beat a null model built to mimic ordinary design choices. What didn't hold up - No golden ratio. φ appears in 6% of formations where chance predicts 8.2% — it's less common than random. - No Fibonacci in element counts. - None of 16 tested constants (√2, √3, π, harmonic ratios) came out above chance. - No match to 4D polytope projections — tesseract, 600-cell, none of them. - Not language-like: no Zipf's law, and the apparent "grammar" turned out to be just "small shapes sit inside big shapes". What did hold up - Complexity roughly tripled across 30 years, with a clear break around 1999. It survives every control I could throw at it. - Six-fold symmetry went from 2.5% of formations in the 90s to 10% after 2010. - Elements are laid out in a consistent order from the centre outwards — reading outward, the next element is far more predictable than chance. The honest caveat, stated at the top of the report: these are measurements of diagrams drawn by an illustrator, not of the fields themselves. So this is evidence about the drawings. That cuts both ways though — a person drawing with digital tools would tidy proportions toward clean ratios, not away from them. Their absence is therefore meaningful. Report, code, raw test log and the pre-registration are all public: https://xxxallistarxxx-one.github.io/crop-formation-analysis/ I also documented three mistakes I made in my own control models and how I caught them — that's in there too, rather than quietly fixed.
