As Øyvind Kolås, the original creator of the ilusion noted: The visual experiment that went along with my previous post went viral, the one that went viral was an already lossily compressed JPEG that has also gone through further cycles of viral degradation by scalings and further JPEG recompressions. He gives a higher quality version: It should ...

Yes. this is the so-called Munker illusion, similar of White's illusion. So named after Munker H (1970): "Farbige Gitter, Abbildung auf der Netzhaut und übertragungstheoretische Beschreibung der Farbwahrnehmung" [Chromatic grids, projection to the retina, and translation theory-based description of the color perception]. In psychology books handling human ...

This phenomenon is just the result of the Agent detection. I asked two similar questions on cogsci.stackexchange which interested people might like to read: Why-is-it-common-for-people-to-default-to-a-single-causal-source-to-explain-new I think it is mostly a result of "hyperactive agency detection"; this results in "single-cause" reasoning as part of ...

I don't like to give simple direct answers, mainly because I don't think I have enough certainty to do so, but also because I prefer to offer the data that I had analyzed and then see if the other person came up with a similar conclusion. I think the core of this tendency to anthropomorphize odd shapes of materials is grounded on the making of false-...
