In this video, Sabine Hossenfelder and Bernardo Kastrup discuss the concept of superdeterminism and how it relates to the measurement problem in quantum mechanics. Kastrup argues that hidden variables exist and that they determine the outcomes of measurements, while Hossenfelder counters that there is no evidence for their existence. They debate the implications of superdeterminism on determinism and metaphysics, and how it can be applied to experiments.

00:00:00 Sabine Hossenfelder and Bernardo Kastrup discuss superdeterminism, a property of certain theories in quantum mechanics that solves the measurement problem. Superdeterminism is a theory-level property, and it is found in the foundations of quantum mechanics. It is designed to solve the problem of the wave function evolving randomly, which is a problem in quantum mechanics.
00:05:00 Bernardo Kastrup discusses the problem of superdeterminism and its implications for the philosophy of science. He agrees with Sabine Hossenfelder that, while theories must be empirically based, metaphysical commitments should not be a guiding principle in science.
00:10:00 Sabine Hossenfelder and Bernardo Kastrup discuss the implications of quantum mechanics on determinism and metaphysics. Kastrup argues that experiments have shown that physical properties, such as mass and charge, do not exist in and of themselves, but emerge as a product of measurement. This necessitates the assumption of statistical independence, which is violated in many cases. Kastrup suggests that the most promising way to pursue determinism is by rejecting local causality in favor of a more global theory.
00:15:00 Sabine Hossenfelder and Bernardo Kastrup debate the existence of physical realism and the nature of hidden variables in theories of physics. Kastrup argues that hidden variables are simply an assumption, while Hossenfelder asserts that statistical independence is a reality that must be taken into account when studying physical theories.
00:20:00 Sabine Hossenfelder and Bernardo Kastrup discuss how classical and quantum physics differ in their assumptions about objects having a standalone existence. Kastrup proposes an experiment in which measurements are made on a quantum system in a way that allows for the hidden variables to be evaluated and falsified. Hossenfelder argues that the experiment cannot be falsified, and that the assumption of standalone existence is an assumption that must be carried over from classical physics to quantum physics.
00:25:00 Sabine Hossenfelder and Bernardo Kastrup discuss superdeterminism, which is the idea that there are mysterious hidden variables that determine the outcomes of experiments. They argue that if superdeterminism is true, then the series of measurements taken in an experiment will be predetermined by the system's initial conditions. If this is the case, then the experiment would be inconclusive. However, they argue that a more general point can be made that superdeterminism is not a theory but a property of a class of theories, and that specific models that propose the existence of these hidden variables can be falsified.
00:30:00 Sabine Hossenfelder and Bernardo Kastrup discuss the concept of superdeterminism and how it can help explain the probability of certain measurements. They also argue about the validity of superdeterminism as a scientific theory.
00:35:00 Sabine Hossenfelder and Bernardo Kastrup discuss the implications of superdeterminism, which states that the outcome of a measurement is determined by hidden variables outside of the particle being measured. They argue that this concept cannot be reconciled with the reality of measurements, in which the measurement settings only influence the outcome if they are in agreement with the evolution law.
00:40:00 Sabine Hossenfelder and Bernardo Kastrup discuss the philosophical implications of quantum mechanics and superdeterminism. Kastrup argues that if we don't have an account of how superdeterminism works, it stretches credulity to believe in it. Hossenfelder counters that even if we don't have a full understanding of how superdeterminism works, it's still possible to make progress on the question of what it means for a physical quantity to be "relational."
00:45:00 Sabine Hossenfelder Λ Bernardo Kastrup discusses the metaphysical implications of superdeterminism in a video. He argues that because physical properties (e.g. photons) have standalone existence, they are non-contextual, absolute, and not relational. He also points out that the coherence phenomenon is not necessary for us to observe the superposition states of photons, and that interference experiments can provide us with accurate information about these states even when the photons are not coherant.
00:50:00 Sabine Hossenfelder and Bernardo Kastrup discuss the concept of superdeterminism and how it can be applied to metaphysics. Hossenfelder notes that an interference experiment can be used to gather information about the superposition state of two particles, even if statistical independence is violated. Kastrup points out that this is an extreme position and that there must be a good reason for departing from statistical independence.
00:55:00 Sabine Hossenfelder and Bernardo Kastrup discuss the disagreement between themselves over whether or not hidden variables exist and how they should be tested. Hossenfelder argues that they do not have any experimental evidence to support their existence, while Kastrup argues that they do. Kastrup also suggests that a theory that is internally consistent and makes predictions should be proposed.

In this video, Sabine Hossenfelder and Bernardo Kastrup discuss the philosophical concept of superdeterminism and how it relates to other theories in metaphysics. Superdeterminism is the view that every event is predetermined by prior events, and Kastrup argues that it is a very plausible theory. The discussion covers the implications of determinism on our understanding of free will, and how superdeterminism might be used to fill in the missing pieces of the puzzle in our understanding of the universe.
