This market resolves to 'Yes' if, by the end of 2050, a device or procedure is demonstrated or well documented in peer reviewed studies that can routinely predict an individual's specific physical actions and nearly perfect internal monologue over a two-minute interval based on starting conditions.

It is acceptable if the prediction cannot happen in real time, so long as it is clearly provable the prediction received no data beyond initial starting conditions. The system must generalize and not work only under contrived conditions. It cannot result in death/clear neurological damage/maiming.
