The discussion centers on the complexities of quantum mechanics (QM) and the interpretation of Richard Feynman's assertion that "nobody understands quantum mechanics." Participants argue that while QM is rigorously tested and understood in terms of its predictive capabilities, it diverges significantly from classical mechanics in its treatment of observables and measurement. The conversation highlights the ongoing debates surrounding interpretations of QM, the measurement problem, and the relationship between quantum theory and classical physics, emphasizing that a deeper understanding of quantum phenomena continues to evolve.

In a Bayesian sense that depends on your expectations :Pphysika said:absence of evidence is not evidence of absence.
If this is strictly correct then there is no inductive scientific method. A scientific hypothesis is accepted because of ongoing absence of any evidence it is not true. This assumes the hypothesis is not a "Pauli"= not even wrongphysika said:absence of evidence is not evidence of absence.
This is Poppers view. Which is why his focus is on corroboration only. I do not like Popper at all. He sweeps the interesting part under the rug just because it is not deductive. But life does not progress in a deductive manner neither i think is learning or natural science. I think Popper just refused to acccept or get to peace with this.hutchphd said:If this is strictly correct then there is no inductive scientific method.
A scientific hypothesis may be "accepted" for as long as it is not contradicted and competes well in the "Occam's Razor" test. But Newtonian physics is "accepted" as a practical engineering tool for most human endeavors - even though it has been contradicted.hutchphd said:If this ["absence of evidence is not evidence of absence"] is strictly correct then there is no inductive scientific method.

How much do you know of Popper's own view and motivations? Are you sure that you won't end up with a similar realization as meFra said:This is Poppers view.

when you will come across explainations of Popper's actual motivations? Or will you be so blinded by his objections to Bayesianism that you won't be able to see the genius of his solution of how to overcome the circularity of induction?For me, it was the opposite. This interview has significantly increased my respect for Deutsch, and also for Popper. It slightly decreased my respect for my own background in philosophy, with respect to what I have read, what I haven’t read, and what I didn’t even plan to read.
Popper realised that the problem of induction actually implies that there's no such thing as justified knowledge in the first place, and that we do not need knowledge to be justified in order to use it.
There is no process of justifying a theory. So theories, according to Popper, are always conjecture, and thinking about theories is always criticism. It's never a justificatory process. It's always a critical process.
