The mirror-of-the-self test helps observers escape subjective preference and learn to see the objective life in things.

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

• The mirror-of-the-self test is not mechanical; its accuracy depends on the observer's level of personal development.claim0.855
  Important caveat about the reliability of the method.
• The Mirror of the Self test ensures configurations are felt, not just observed by members.claim0.850
• mirror of the self testmethod0.834
  A method introduced in Book 1 where observers compare their feeling of self with the life in a candidate thing; Alexander claims it correlates with observed life in thousands of centers.
• "the self-prior can serve as an internal criterion for the mark-directed behavior observed in the mirror test, offering a computational basis for investigating the developmental origins of self-awareness"quote0.828

• The mirror-of-self criterion allows a person with almost no training, after a few hours, to make quality judgments of carpets that would normally require years of connoisseurship.finding0.816
  Empirical finding cited in Book 1 regarding oriental carpets, recapitulated in the Mid-Book Appendix to support the universality of the self-criterion.
• Mirror-of-the-self experimentmethod0.809
  Experimental protocol developed by Alexander in the 1970s: subjects compare two configurations and choose which is more like their eternal self, yielding consistent cross-cultural agreement.
• Mirror of the self is a foundational concept in self-aware cognition.claim0.805
• What does the mirror-of-the-self experiment mean?question0.801
  The question Alexander poses about the ontological implications of the experiment.
