We construct a universal prediction system in the spirit of Popper’s falsifiability and Kolmogorov complexity. This prediction system does not depend on any statistical assumptions, but under the IID assumption it dominates, although in a rather weak sense, conformal prediction. Not for nothing do we call the laws of nature “laws”: the more they prohibit, the more they say. The Logic of Scienti...

The spectacularly varied responses to our target article raised big-picture questions about the nature of seeing and thinking, nitty-gritty experimental design details, and everything in between. We grapple with these issues, including the ready falsifiability of our view, neuroscientific theories that allow everything but demand nothing, cases where seeing and thinking conflict, mental imagery...

This article reviews two standard criticisms of creationism/intelligent design (ID)): it is unfalsifiable, and it is refuted by the many imperfect adaptations found in nature. Problems with both criticisms are discussed. A conception of testability is described that avoids the defects in Karl Popper's falsifiability criterion. Although ID comes in multiple forms, which call for different critic...

Intelligent Design Theory (ID) has been much maligned recently as Neo-Creationist pseudoscience. This paper looks briefly at the common arguments used against ID, including arguments from methodological naturalism (MN), falsifiability, productivity, and religious fundamentalism. Ultimately it goes on to explain why the theory could be beneficial to our society today and suggests a need for a me...

A test of quantum mechanics proposed by K. Popper and dealing with twoparticle entangled states emitted from a fixed source has been criticized by several authors. Some of them claim that the test becomes inconclusive once all the quantum aspects of the source are considered. Moreover, another criticism states that the predictions attributed to quantum mechanics in Popper’s analysis are untenab...

This paper studies the falsifiability of two-sided matching theory when agents’ preferences are unknown. A collection of matchings is rationalizable if there are preferences for the agents involved so that the matchings are stable. We show that there are nonrationalizable collections of matchings; hence, the theory is falsifiable. We also characterize the rationalizable collections of matchings...

We argue that with the discovery of neutrino mass effects at Super-Kamiokande there is a clear logical chain leading from the Standard Model through the MSSM and the recently developed Minimal Left Right Supersymmetric models with a renormalizable see-saw mechanism for neutrino mass to Left Right symmetric SUSY GUTS : in particular, SO(10) and SU(2)L×SU(2)R×SU(4)c. The progress in constructing ...
