Is Liu Yao Accurate? Evidence and Limits
Separate repeatable Liu Yao chart calculations from historical doctrine and predictive claims, including conclusions the evidence cannot support.
Overview
A Liu Yao cast can be replayed when its seed or coin faces, line order, time, timezone and rules are preserved. That demonstrates calculation reproducibility, not that the symbols predict events. Historical texts document traditions, while accuracy requires a separate, preregistered and outcome-based evidence design that these sources do not provide.

Direct answer
A Liu Yao cast can be replayed when its seed or coin faces, line order, time, timezone and rules are preserved. That demonstrates calculation reproducibility, not that the symbols predict events. Historical texts document traditions, while accuracy requires a separate, preregistered and outcome-based evidence design that these sources do not provide.
Definitions and prerequisites
Evaluate four layers independently: input provenance, deterministic calculation, attributed interpretive rule, and external outcome evidence. A page must not borrow confidence from a strong calculation test to make an unsupported claim about a person or future event.
Method or reference rule
Audit a claim by asking what could falsify it, whether the outcome was defined before the cast, whether misses were retained, and whether a neutral comparison exists. Keep chart correctness and outcome validation as separate test reports.
Worked example
A stored cast producing the same hexagram on two devices is evidence that the implementation replays correctly. It is not evidence that a later job offer, recovery, payment or relationship event was caused or forecast by that hexagram.
Closest failure case
Collecting only memorable “hits,” changing the question after the outcome, or counting broad metaphors as success creates confirmation bias. Repeated casting until a preferred result appears makes the record less, not more, probative.
Sources, interpretation and limits
No source used here establishes a reliable predictive rate for Liu Yao. Use interpretations as bounded prompts, state uncertainty, retain alternative explanations, and verify decisions with appropriate real-world evidence.
The scholarly source supports the history and uses of the Yijing, while OpenFate supplies an editorial safety boundary. Neither is evidence of predictive accuracy.
Verification checklist
Save the question, cast time, timezone, face convention, six line values, source edition and product version whenever they can change the result.
- Reproduce the six stored line values before interpretation.
- Name the method, edition and product settings used.
- Cite the decisive chart facts instead of one dramatic label.
- Use observable records and qualified advice for high-stakes decisions.
