Value Change vs. Value Corruption
Not all value change is a threat. The distinction between legitimate value change and corruption is load-bearing for everything the book calls correction.
What decision changes?
Before treating a shift in stated or revealed values as evidence of drift, ask whether it moved through processes people would endorse on reflection, or through manipulation, coercion, or dependency.
Human values already change over a lifetime, across cultures, and across generations — through education, argument, trauma, and technology. A theory that treats every value change as corruption would forbid ordinary moral growth; a theory that treats every value change as acceptable would license manipulation.
The book’s response is to separate the two by process rather than by outcome. Value change is legitimate when it moves through channels a person would endorse under reflection: honest argument, lived experience, deliberation. It becomes corruption when it moves through manipulation, coerced dependency, or a system engineering the update it wants approved.
This distinction is what later chapters on correction-channel integrity and manipulation build on. A correction channel that can only detect “values changed” without judging how they changed cannot tell legitimate moral progress from domestication.
