Through the story of Alex’s investment journey, this sci‑comm essay introduces the Neural Pathway Fallacy (NPF) factors—Lazy Thinking, Special Reasoning, Neutral Pathway, Spillover—and the Composite NPF Index (CNI) as a proposed measure of belief‑network entrenchment. It then shows how protocols like the Binary Belief Protocol, Proportional Scrutiny, prebunking, cross‑training, and dopamine rechanneling can help loosen entrenched networks.

Beliefs don’t stay isolated—they cluster into networks that can become self‑reinforcing and resistant to evidence. This essay introduces cognitive synergy, ideological scaffolding, cross‑domain spillover, and the Composite NPF Index (CNI) as a proposed way to summarise systemic epistemic risk. It also touches on cultural calibration and why context matters.

The Composite NPF Index (CNI) extends the Neural Pathway Fallacy to belief networks, quantifying systemic epistemic risk. This paper presents the CNI formula (weighted sum with normalised weights), normalisation methods (linear, sigmoid with cultural parametrisation), sampling adequacy, and a gradient‑descent weight update (hypothesis). It introduces the neurodiversity provision (autistic resistance to high‑SE NPFs) and positions CNI within the Fractal Entailment Network (FEN
