The truth is that testing any such notion about the probability by repeating the trial shows that no single value of the probability is appropriate. Alternatively, for most 1p observers, any particular theory about the probability will be disconfirmed. The first person data is the particular bit string recorded by an individual. From the 3p perspective, there are 2^N different 1p bit strings after N trials.
