Discussion Overview

The discussion centers around the existence of true randomness in reality, exploring its implications in various contexts such as quantum mechanics, philosophical interpretations, and practical applications. Participants examine whether randomness is a fundamental aspect of nature or merely a reflection of our ignorance and limitations in knowledge.

Discussion Character

  • Exploratory
  • Philosophical
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants question whether true randomness exists or if all seemingly random events can be explained by underlying physical processes.
  • Others propose that randomness may be a useful concept rather than a definitive characteristic of reality.
  • A few participants argue that randomness in real-world applications often quantifies our ignorance rather than indicating true unpredictability.
  • One participant mentions Bell's theorem and hidden variables as a framework for discussing randomness in quantum mechanics.
  • Another participant cites quantum effects, such as radioactive decay, as examples of true randomness, while noting the philosophical implications of proving such randomness.
  • Several participants use the example of predicting outcomes in tennis matches to illustrate the complexities of knowledge and prediction in seemingly random events.
  • Discussions also touch on the limitations of knowledge regarding external factors that could influence outcomes, emphasizing the challenge of predicting events with complete accuracy.
  • Participants reference the Stern-Gerlach experiment as an example of randomness in quantum measurements, highlighting its counterintuitive nature.

Areas of Agreement / Disagreement

Participants express a range of views on the nature of randomness, with no consensus reached. Some argue for the existence of true randomness, particularly in quantum mechanics, while others maintain that randomness is a reflection of our incomplete understanding of complex systems.

Contextual Notes

The discussion includes various assumptions about knowledge, measurement, and the nature of reality, with participants acknowledging the limitations of their arguments and the potential for hidden variables influencing outcomes.

Does the fact that a deterministic model describes a system to the level of precision that we care about make the underlying phenomena deterministic to any arbitrary level of precision (which TRVE determinism would imply)?
No, but to me it suggests that it wouldn't be unreasonable to act on the basis that those phenomena are fundamentally deterministic at some level of awareness (unless doing so made one miserable.)
