Sorry, I meant to say “the most irrational numbers”.
Have a look at this book around page 85-89 if you want to get a feel for what I’m talking about.

In grad school I was interested in whether various perceptual anomalies, including McCullough’s reports, could give insight into perception; I ran across some papers in the late 80s or early 90s discussing these topics. The general topic of critical slowing down and critical behavior in neuroscience has been developed quite a bit since then, I’m not really an expert. I’m just suggesting that if you managed to reproduce W.M.'s data and were interested in explaining it, this might be the direction to look. We would need to be able to internally measure or sense convergence rates of dynamics; in my view it’s a pretty fundamental property underlying perception.
