@VikingWays @TrevorGoodchild @judgedread The popularization comes from a 4chan post. The Anon allegedly had knowledge of a few ways to determine someone's rough IQ depending on what level of complexity they could handle.
Failing the breakfast question puts someone near 80 IQ. For around 90 IQ there was a challenge about comprehending a story with a story happening within that first story. This test can be made much harder and inaccurately test for even higher IQ levels by making it a story with a story in it, and that story also has a story in it.
