Vertical vs. Horizontal Defense Protocols: An Evolutionary-Cognitive Load Minimization Analysis of Gendered Conflict Dynamics

This paper examines the structural mechanisms of conflicts between men and women through the integrated framework of evolutionary anthropology, cognitive science, and Load Minimization Theory (LMT). We formalize male-typical cognition as primarily Vertical Protocol (status negotiation and hierarchical resolution) and female-typical cognition as Horizontal Protocol (relational coherence and community maintenance). Using the fundamental LMT equation L = U + F + E, we develop a dynamical systems model that demonstrates how protocol mismatch generates mutual Load Dumping and positive feedback loops. When conscious Defensive Re-Tagging and Protocol Bridging are applied, the system converges to a low-load An-soku equilibrium. Everyday examples such as unread messages illustrate how small triggers can escalate, while Tier-3 strategies convert friction into deeper mutual understanding. This work offers practical pathways toward structural ease in intimate relationships.
