The Three Theorems of Psychohistorical Quantitivity:
- The population under scrutiny is oblivious to the existence of the
science of Psychohistory.
- The time periods dealt with are in the region of 3 generations.
- The population must be in the billions (±75 billions) for a
statistical probability to have a psychohistorical validity.
These three theorems were put forward by Hari Seldon at the Decennial Conference for
Mathematics at Trantor, just before the
meeting with Chetter Hummin and the Flight.
The theorems are a quantisation of what is necessary for the
statistical consideration of the probabilities involved with the futures of a population.
If Psychohistory could (which is true, it is hastened to add) be
considered an exotic form of differential equation, then the theorems may be considered to
be the initial conditions for a general solution.
