Welcome to Weekly Ichikawa Quiz — a fun, fast way to test what you know and learn something new every week.
This site is inspired by the work and ideas of Jonathan Ichikawa and the kind of topics people love to think about: knowledge, reasoning, philosophy, and everyday questions that make you go, “Wait… is that actually true?”

Mixed topics (general knowledge, logic-style questions, philosophy-friendly prompts, and “did-you-know” facts)
