Corrections, suggestions, and requests for paradoxes the compendium should cover are all genuinely welcome.
unspurious is an educational project, and it gets better when readers push back. If you have spotted an error in an explanation or a figure, if something is unclear, or if there is a statistical illusion you think belongs in the collection, please write in.

A few things that are especially useful to include: which page you are writing about, the specific claim or figure in question, and — for a suggested new entry — a real-world case where the illusion bites. The roadmap of in-preparation entries is shaped partly by what readers ask for, so concrete examples carry real weight.
For background on the project's approach and its limits, see the about page.
