Friends, Darn it! I cant get anybody to tangle with the fundamental thing I am saying here. Anytime we embody something that is true of the aggregate of observables in a single unobservable case, we are committing a fallacy. The locus classicus of this fallacy is mental causation, where we hy

Sure, data is good to have, but what would past behavior tell you about the novel aspects of new behavior, and how would you be able to tell that from incomplete data on the past, anyway? For original behavior it would seem the usual tools don't help much, unless you do what I do and. turn mode

So she seems to be saying that developing systems, at our scale, as they acquire experience/structure, regularly encounter coupled pairs of observables that cannot be simultaneously measured to 'high' precision? Pioneering work, indeed, but challenging for the modeler! Certainly messes with t

Hi Nick, I assume you already know about the work Judea Pearl did to define a notion of causality in the context of inference on Boolean networks? I don't have citations on this, because I only learned about it recently in someone's talk, but I gather it is fairly widely known. Happily it doesn't
