Ad Microtargeting: Precision Propaganda vs Broadcast Reach

This simulator visualizes the mechanic behind coordinated influence campaigns that platforms and regulators try to detect: audience microtargeting. A population of 1,600 simulated people is laid out across two psychographic axes — political lean and media trust — each with a fixed susceptibility to persuasion. Launching a campaign pulse spends a fixed ad budget either broadcast uniformly across everyone or concentrated with a targeting kernel on the most persuadable cluster; the terrain rises and reddens wherever belief has shifted toward the campaign's message. Live readouts track average belief shift, targeting ROI (persuasion per unit of spend), audience reach and population polarization, and an ad-library disclosure toggle shows how platform transparency rules blunt the efficiency advantage that precision targeting has over honest broadcast messaging — the same defensive mechanism real ad-transparency mandates use against propaganda operations.
