Could you build this?

No Developing a novel 'System One decision model' involves fundamental artificial intelligence and cognitive decision modeling research.

What it would actually take: Requires novel AI/ML architecture design focusing on intuitive, fast heuristic generation (Kahneman's System 1) as opposed to autoregressive reasoning chains (System 2). Building it requires deep machine learning research expertise, specialized training corpora, fine-tuning infrastructure (PyTorch/JAX), and novel loss/reward function designs.
