Coherence in
Coherence Dynamics Theory
In CDT, coherence is dynamic directional continuity: a system's ability to preserve a coherent trajectory by detecting deviation, activating correction, and restoring alignment over time.
Definition
Coherence is maintained direction, not static perfection.
CDT uses coherence to name the condition in which an adaptive system preserves directional continuity despite ongoing perturbation.
A coherent system is not one that never deviates. It is one that can detect deviation, correct it, and keep returning to its directional baseline often enough to preserve its trajectory.
"Coherence is not static equilibrium. It is maintained direction."
Coherence Dynamics Theory — Working Definition
What Coherence Is
Dynamic
Coherence is maintained through activity, detection, and correction. It is not a fixed or frozen state.
Directional
CDT cares about whether a system preserves its trajectory over time, not merely whether it remains operational.
Emergent
Coherence emerges from repeated successful correction. It cannot be assumed from intention alone.
Distributed
In coupled systems, coherence depends on whether correction can propagate through the system faster than deviation does.
What Coherence Is Not
Coherence is not perfection.
A coherent system can still drift. The question is whether it can return often enough to preserve direction.
Coherence is not rigidity.
A coherent system can adapt, reconfigure, and even change regime without losing directional continuity.
Coherence is not static equilibrium.
Static equilibrium implies stillness. CDT is concerned with adaptive systems that remain alive by continually moving and correcting.
How Coherence Holds
Detection
The system registers meaningful deviation.
Regulation
Correction mechanisms activate instead of remaining inert.
Return
Direction is restored rather than merely discussed or intended.
Reintegration
The correction re-enters live system operation and becomes stable again.
Related Concepts
Drift
If coherence names maintained direction, drift names the persistent force pulling a system away from that direction.
