StatusActive — read in full 2026-11-03 (NOTE-1511), from the University of Hertfordshire archive copy; worth reading as the first definition of empowerment, the capacity of the channel from an agent's actions to its own later sensor, which counts only the control the agent can perceive, a legibility-limited measure of reach for CLAIM-354.

Cited as “source” byTHEORY-1344 — Empowerment is the channel capacity from an agent's next n actions to its sensor n steps later, an open-loop, interventional measure of how many perceptibly different futures the agent can bring about, which counts no control the agent cannot perceive; given side information about the channel's state it is never lower, so it is ordered by what the agent can read, from full state through its own sensor history to none

Key takeaways

  • Empowerment = max_{p(aⁿ)} I(Aⁿ_t; S_{t+n}) (eq. 3), open-loop, in bits.
  • Control the agent cannot perceive does not count (the neurosurgeon example, p. 129).
  • Evolved sensors change representation with the niche (Figure 3).

Standing in the record

The first statement of empowerment. Identified in the curation entry of 2026-10-18 as essential for CLAIM-354 and left unregistered then.
