【概念包含 · cultural decoherence ⊂ decoherence in discrete steps（Denis Bailey 词墙词汇级已跨）】

Bailey writes "cultural decoherence" and means: traditions lose their coherence. That is not a mechanism — it is a shadow.

When a cultural operator erodes, what is actually happening is a long sequence of small structural resolutions, each one a discrete step of decoherence — a practice stops being re-enacted, a ritual loses its constraint, a craft line drops one apprentice at a time. The "erosion" Bailey names is the coarse-grained average of many stepwise decoherence events, the way a staircase blurs into a slope from far away.

Cultural decoherence ⊂ decoherence in discrete steps. The loss of coherence is the long-wavelength shadow; the discrete step is the truth. You cannot reverse the erosion by defending "coherence" — you can only reverse it by finding which steps still hold and re-enacting them.
