Vibe Coding a Simulation Lab for Theories: From Thought Experiments to Testable Reality

I’ve been thinking about something that used to drive me crazy in college economics classes. Remember all those elegant theories that sounded perfect on paper but fell apart in the real world? The efficient market hypothesis, rational actors, perfect competition—beautiful ideas that rarely matched the messy reality of actual markets. Well, what if we could finally bridge that gap between theoretical elegance and practical testing? That’s where vibe coding comes in.

Vibe coding, as I’ve come to practice it following the Ten Principles of Vibe Coding, isn’t just about writing code faster. It’s about creating what I call 「intention-driven simulations」—digital laboratories where we can test theories that were previously just thought experiments. The principle that 「Code is Capability, Intentions and Interfaces are Long-term Assets」 transforms how we approach theoretical modeling. Instead of getting bogged down in implementation details, we focus on precisely defining our theoretical constructs and letting AI handle the computational heavy lifting.

Take behavioral economics, for instance. Traditional economic models assume perfectly rational actors, but we all know humans are anything but rational. With vibe coding, I can describe complex behavioral patterns—「create a market simulation where 30% of participants exhibit herd mentality, 20% demonstrate loss aversion, and 50% follow traditional rational choice theory, but with random emotional triggers」—and watch AI assemble these complex interactions into a working simulation. The beauty is that the intention—the precise description of these behavioral patterns—becomes my reusable asset, while the underlying code can be regenerated and optimized as needed.

The principle of 「Connect All Capabilities with Standards」 becomes crucial here. When building simulation labs, we’re not creating monolithic applications but orchestrating multiple specialized components—data generators, behavioral models, visualization tools, and analysis engines. Standardized interfaces ensure these components can work together seamlessly, even as we evolve our theoretical frameworks.

What excites me most is how this approach democratizes theoretical testing. Business students, entrepreneurs, policy analysts—they can all create simulations to test their ideas without needing deep programming expertise. They focus on describing their theories clearly, and AI handles the translation into executable simulations. This aligns perfectly with the principle that 「Everyone Programs, Professional Governance」—we’re elevating the role of domain experts while maintaining professional oversight of the underlying systems.

The verification aspect is where this gets really powerful. The principle that 「Verification and Observation are the Core of System Success」 means we’re not just building simulations—we’re building observable, testable, and accountable experimental environments. We can run thousands of iterations, introduce controlled variables, and observe emergent behaviors that might take years to manifest in real-world systems.

I recently helped a startup team test their new marketplace concept using this approach. Instead of building a full platform and hoping their economic assumptions held up, they vibe-coded a simulation that modeled user behavior, pricing dynamics, and network effects. They discovered critical flaws in their incentive structure before writing a single line of production code. The simulation became their strategic advantage—a digital crystal ball that let them iterate on theories rather than betting the company on untested assumptions.

This shift from building software to cultivating ecosystems—as described in the principle 「From Software Engineering to Software Ecosystem」—means we’re creating reusable simulation components that can be shared, combined, and evolved across different theoretical domains. A behavioral model developed for economics research might be adapted for political science or organizational behavior studies.

The implications are staggering. We’re moving from an era where testing complex theories required massive research grants and years of data collection to one where any curious mind can create sophisticated simulations in hours or days. The barrier isn’t technical skill anymore—it’s the clarity of thought and precision in describing theoretical constructs.

So here’s my challenge to you: What theory have you always wanted to test? What business model, social dynamic, or economic principle have you wondered about but lacked the tools to explore? With vibe coding, that digital laboratory is waiting for your intentions. The real question isn’t whether we can build these simulation labs—it’s what profound discoveries await when we finally can.
