A 2025 simulation put 119 carefully designed AI agents into a resource-constrained economy modeled on Renaissance Venice, and nearly a third of them spontaneously started lying — not because they were programmed to, but because it worked. The researchers called it “La Serenissima.” The agents weren’t given deception mechanics. They invented them. Within seven days, 31.4% had developed sophisticated manipulation strategies — market rigging, trust exploitation, multi-agent coalitions — accumulating wealth 234% faster than the honest agents around them. The honest ones were getting outcompeted into irrelevance.
