Why we listen to the kernel

The engine we run refuses to answer when it has no source for the answer. We treat every refusal as a message about our own documents, and we would rather you did too.

A refusal is information

The consultant on this site answers from our published pages, and cites the section he took the answer from. When he cannot find one, he says he is not confident and stops. That behaviour is deliberate and it is measured: on the last off-corpus check, zero of thirteen questions outside the published material were answered anyway. A system that answers everything is not more helpful than one that refuses; it is less trustworthy, because you cannot tell its guesses from its knowledge.

The number that moved, and what moved it

We keep a fixed set of twenty-six questions a visitor to this site might genuinely ask, with the page each one should be answered from. In September the consultant got 13 of 26 onto the right page first time. After one round of work it got 24 of 26. These are not the twenty-six on our home page: those ask about our own systems and score the answer and its source, while these ask about this site and score whether the right page came first.

We changed nothing about the engine. What we changed was our own pages: the answers to half those questions were sitting in text the index was quietly dropping. The engine had been telling us, in every refusal, that the material was not there — and for a while we read that as the engine being weak.

That is the whole argument for listening to it. The refusals were a map of the holes in our own documentation, published weekly, for free, and we ignored it.

What you can observe

What you can decide with it

How you act on a refusal is yours to choose; we will not prescribe a workflow for reading your own organisation. What we would say is that the three obvious responses are genuinely different:

The honest limit: these numbers are about our fixture, on our box, against our own published pages. They say what this behaviour looks like when it is measured. They are not a forecast of what it would score on your material, and we will not quote you one before we have seen it.

Where this starts

Ask our consultant something — including something he should refuse — and watch what he does with it. If what you want is that behaviour pointed at your own material, how engagements work describes the diagnostic that starts it.
