I have, and it’s hard to disambiguate the effects because they do overlap. But I think the experiment had an effect because I noticed it strengthening while I was looking at that background image every day, and then there was a sharp dropoff after I stopped using that background. If I had bothered to graph it, I expect the relationship between “number of days since using that background” and “number of illusion incidents in the wild” would have looked like a power curve. Unfortunately I am not much of a data collector, more of a casual data observer, so I may never know for sure 🤷
