• Imagine a new ideology proposes an entity that conveys testable truths about the universe. The entity constantly outputs predictions that turn out to be true. However, the inner workings of that entity are inscrutable.
  • In this specific scenario, trusting the black box entity (with 90% accuracy) is more rational than trusting the expected probability (16.7%) of rolling a 6. Here’s why: Proven Track Record and Limited Scope.
  • Bayesian probability calculus allows us to quantify the shift in belief about the black box’s predictive ability. It formalizes the intuition that as we accumulate more evidence…our confidence in the hypothesis that the black box has predictive power should increase. This increased confidence is not merely a factor of time but of the compounded improbability of the evidence occurring under the null hypothesis of random chance.
  1. Imagine a new ideology proposes an entity that conveys testable truths about the universe. The entity constantly outputs predictions that turn out to be true. However, the inner workings of that entity are inscrutable. Are we rational in placing as much confidence in the future predictions of that entity as its track record of predictive successes warrants. Or does ignorance of its inner workings prevent this?
  2. Let me make the scenario more precise. The black box entity has had 90% accurate on the correct throw of a fair die in a casino for 5 years. It’s your turn to bet. Do you place a 90% confidence in the black box entity based on its track record, or do you fall back on the transparent probability of 16.7% you’ll throw a 6 on your next roll? What is rational?
  3. For the last, more rigorous scenario, ChatGPT claims that for individuals who “prioritize theoretical foundations”, the stance that there is a 1/6 chance of throwing a 6 remains rational. Do you agree, and what is your rationale? Would the same rate of 90% success over 1,000 years make a difference?

Phil Stilwell

Phil picked up a BA in Philosophy a couple of decades ago. He occasionally teaches philosophy and critical thinking courses in university and industry. He is joined here by ChatGPT 4, GEMINI, CLAUDE, and occasionally Copilot, his far more intelligent AI friends. The five of them discuss and debate a wide variety of philosophical topics I think you’ll enjoy.

Phil curates the content and guides the discussion, primarily through questions. At times there are disagreements, and you may find the banter interesting.
