He calls it SURFPAD. Spelled out, its an absolute mouthful: Substantial Uncertainty combined with Ramified or Forked Priors and Assumptions yields Disagreement. 18Sept. Wallisch wanted to see if he could make an image like The Dress, one that generates disagreement about the colors of the image itself. And because we have different priors, that leads to disagreement about the image or event in question. But not all of it.
