Bayesian Reasoning
A friendly FAQ on priors, evidence, and AI assistance
Words such as “unlikely” already contain judgments. Bayesian reasoning puts those judgments where others can inspect and challenge them.
The argument
Worked examples introduce updating while distinguishing exact arithmetic from reliable inputs. Expanded discussion addresses historical likelihoods, compounding judgment errors, search selection, open alternatives, joint sensitivity and AI anchoring. The FAQ explains both the uses and limits of explicit numerical analysis.
How to read this assessment
A transparent calculation is not automatically calibrated. Teaching ratios are labeled as assumptions, qualitative uncertainty remains legitimate, and agreement between AI systems is not independent validation.
A question worth pursuing
Which assumption would have to change for you to reach a different conclusion?
