Interference Removal vs Behavioural Modification: Why Behaviour Change Does Not Hold

This white paper argues that behavioural modification and interference removal act at different levels of the human system and therefore produce different classes of outcome. Across psychology, coaching, self-development, and behavioural models, intervention is often applied at the level of visible output: behaviour, emotion, interpretation, or self-management. This paper proposes that such intervention is structurally late. Building on the causal frame established in White Paper 1 — configuration → routing → physiology → behaviour — the paper argues that behaviour is a downstream expression of routed system state rather than a primary site of causation. It shows why output-level change can appear effective while remaining unstable under pressure, and why durable change requires intervention at the level of the producing condition rather than the visible expression. This is White Paper No. 2 in the ongoing series on The Codex System by Judy van Niekerk, known online as Judy Vee.
