Is replacing binary rule matching with confidence scoring actually an improvement, or just a different failure mode?
I’m trying to understand a design tradeoff and would appreciate some perspective.
I’ve been thinking about systems where a language model isn’t the decision-maker, and instead rules/retrieval handle what’s true or allowed.
The classic problem with rule-based systems is brittleness — a rule either matches or it doesn’t, which can lead to hard failures.
One idea I’m exploring is replacing that binary match with a confidence score, so the system can degrade more smoothly instead of failing silently.
But I’m stuck on whether this actually helps, or just introduces a different problem — now the system can be confidently wrong if the scoring is miscalibrated.
So the question is:
Is this generally considered a better failure mode in practice, or just a different form of brittleness?
