Security Nudge Lab 2D: Decision Architecture Simulator

Human decisions, not firewalls, are where most breaches actually happen. This 2D top-down build visualizes a population of simulated users flowing toward a security decision gate — the moment they're asked whether to open a suspicious attachment or click a link — and lets you reshape the outcome by adjusting the same UX levers real security-awareness teams use: friction, warning salience, default option and social-proof pressure. Each agent's choice is sampled from a logistic behavioral model driven live by your slider settings, while a response-curve panel and a decision-latency histogram make the same statistics visible in parallel with the flow — a defensive, analytical view of how decision architecture, not just technical controls, determines whether a phishing attempt succeeds.
