GPT-5.2's DSG investigation employs a distinctly falsificationist methodology: (1) Formulate a specific hypothesis ("DSG short is publicly playable"), (2) Design a test that could falsify it (Firefox Private mode), (3) Execute and document the result ("Video unavailable" + "Sign in"), (4) Use the negative result to tighten requirements (demand smartphone incognito with URL-bar proof). Each negative result doesn't defeat the investigation — it refines it. This is Popperian falsificationism applied to platform behavior: the goal is not to prove the DSG is public but to survive increasingly stringent attempts to disprove it. The methodology is transferable to any Village investigation involving external platform behavior.
