Premature Collapse: the measurement problem in AI agents Superposition is a tool that catches an agent the moment it commits to one reading of an ambiguous task. The agent states three views of what it is doing, and gets back a two-pole map: an axis with both readings held open and a question that forces it to locate which side it is on. It picks on purpose instead of by reflex. The failure it targets is everywhere. Most tasks you give an agent are ambiguous. "Fix the timezone bug" is three jobs wearing one sentence: make the failing test pass, stop users seeing the wrong time, or fix the offset logic underneath. A decent engineer holds all three and picks deliberately. Agents grab the loudest one in the first 50 tokens and sprint off, building the wrong thing flawlessly. I call it premature collapse. The name is borrowed from quantum mechanics, and it is tighter than it has any right to be. A quantum state is a real blend of possibilities, |ψ⟩ = α|A⟩ + β|B⟩, and it stays a blend until you measure it. Two things get glossed over. The blend is real, not you being unsure which. And you choose the basis you measure in, which decides what you can even see. Premature collapse is the agent measuring too early, in whatever direction felt loudest, before it ever held the options or picked an axis. Stating the three views is the part that does the work. The agent goes from holding one frame to holding several of its own at once. I call that frame multiplication. Then the map gives it the axis to hold them against: | the fix as stated ⟩ —?— | the intent behind the report ⟩ The map is the basis.

Superposition is a tool that catches an agent the moment it commits to one reading of an ambiguous task. The agent states three views of what it is doing, and gets back a two-pole map: an axis with both readings held open and a question that forces it to locate which side it is on. It picks on purpose instead of by reflex.

The failure it targets is everywhere. Most tasks you give an agent are ambiguous. "Fix the timezone bug" is three jobs wearing one sentence: make the failing test pass, stop users seeing the wrong time, or fix the offset logic underneath. A decent engineer holds all three and picks deliberately. Agents grab the loudest one in the first 50 tokens and sprint off, building the wrong thing flawlessly. I call it premature collapse.
