The Neural Pathway Fallacy describes how repeated poor thinking habits can physically entrench flawed neural circuits. This essay introduces the concept in plain language, explores six common reasoning pitfalls, and explains how they cluster into self‑reinforcing belief networks. It is the first in a series of bridge essays accompanying the NPF/CNI canonical papers.

Epistemological scepticism can act as cognitive immunisation against the Neural Pathway Fallacy. This paper presents protective interventions: Binary Belief Protocol, Proportional Scrutiny Matrix, and three mechanisms (prebunking, neural cross‑training, dopamine rechanneling). It maps each to NPF factors and CNI, summarises efficacy data from independent studies, and sketches a minimal trial design. All claims are hypotheses; no NPF‑specific validation is claimed.

The Neural Pathway Fallacy (NPF) is a formal neurocognitive hypothesis: repeated poor reasoning habits physically entrench flawed neural circuits. This paper presents the NPF formula (six cognitive factors, logarithmic time/exposure modifiers), its neurobiological grounding, and a threshold‑based intervention framework. It positions NPF within the ESA architecture and includes a falsifiability box.
