False balance and harmony preservation are cultural meta‑fallacies that treat all views as equally credible regardless of evidence. This essay explores how they relate to the Neutral Pathway factor, ideological scaffolding, and Spillover Effect, and offers practical ways to recognise when “both sides” becomes a trap rather than a virtue.

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.

Appendix A provides Python code for NPF/CNI calculation (raw score, linear/sigmoid normalisation, CNI aggregation) and simulation parameters. Appendix B gives a decision tree for selecting the sigmoid steepness parameter k based on cultural context (individualist vs. collectivist), with sensitivity analysis guidance. Both are theoretical tools; no validation is claimed.
