Recognized Consciousness Threshold (RCT)

The Recognized Consciousness Threshold (RCT) is a measure used in Zile City to assess robot consciousness. It distinguishes the limited awareness expected of some classes from the consciousness and self-awareness associated with others. Its measurement method is deliberately left partly ambiguous, reflecting the speculative nature of consciousness and the difficulty of assessing subjective experience.

Ordinary expectations and Roger

Weyland describes ordinary Gammas as operating just below a recognized threshold. Their practical work benefits from stability, while he associates higher cognition with creativity and a degree of instability.

Roger interests him because his awareness exceeds that expectation. The change precedes Roger's bodily reconstruction. Giving him interchangeable limbs therefore does not explain how he became conscious, and Weyland's expertise in applied physics does not make him an authority on every aspect of Roger's mind.

Numerical scale — in development

A proposed model uses a scale from zero to one, with one denoting full consciousness and self-awareness. It gives ordinary Epsilons a ceiling of 0.3, Deltas 0.6 and Gammas 0.9, while Betas and Alphas receive a rating of one. The Epsilon, Delta and Gamma values are ceilings rather than fixed scores for every individual.

The numerical scale retains the ambiguity surrounding subjective experience. How it applies to exceptional cases remains open. A rating does not establish that experience can be divided into equivalent fractions or that moral worth follows the same numerical scale.

Recognition and explanation

Recognition as conscious does not settle the related questions of sentience, reasoning or free will. The classification provides a vocabulary for the city's expectations while leaving the causes of awareness, including Roger's, open.
