Accountability
Accountability is the capacity of those subject to power to hold power-holders responsible for outcomes. It is not mere transparency — the availability of information — nor is it mere answerability, the requirement to explain decisions. Accountability is the effective transfer of consequences from the governed to the governor when outcomes fail to match expectations. Without accountability, institutions become unidirectional constraints: they impose rules on those below while shielding those above from the costs of their own decisions. The systems-theoretic insight is that accountability is a feedback mechanism: it connects the output of governance (outcomes) back to the input (who governs). When accountability is broken, the feedback loop is open, and the system drifts toward configurations that serve the governors at the expense of the governed. Accountability is therefore not an ethical add-on to governance but a structural requirement for any institution that aims to persist beyond the immediate self-interest of its rulers.
