From Numerical Deviation to Biological Switch: Gene-Based Tunnelling Control of Human Peaceful Violent Dual State

Every human carries a dual nature: a Peaceful state and a Violent state. Pre-vious models described this duality as a numerical deviation ∆, where ∆ = 0 isPeaceful equilibrium and ∆ > 0 is Violent deviation. Such numerical examplesremain simulation, not reality. This paper moves from numerical to biological byidentifying the gene-based ON/OFF switch.We propose that the Zulfia Gap Gzulfia = Creal −Cseparable is biologically realizedas a differential gene expression gap. Three switches are documented:• MAOA (Warrior Gene) as primary ON/OFF switch,• SLC6A4 (5-HTTLPR) as serotonin transporter switch,• COMT Val158Met, DRD4, AVPR1a as environmental modulators η.State transition follows Tη : S → S′, where S′ = S+η(y, x) and η = Gene Expression×Environment.When Gzulfia > 0, MMI tunnelling from Peaceful to Violent state. Finding thisbiological switch provides a reality check beyond numerical example. We do notpropose gene editing. We propose documentation only, via a low-cost $500 gene testfor awareness. We propose documentation and a $500 factory test for awareness,which is upstream science. This is history, not application of old theories.
