Split-Domain Cognition
A principle for keeping language work and judgement work structurally apart — in tools, practices, and institutions reasoning about human work.
When language work and judgement work are fused in a single call, certain failures appear reliably: verdicts that cannot be audited, descriptions that smuggle evaluation, rubrics that cannot be taught, drift under pressure, sycophancy in machines. SDC is the refusal of that collapse.
