Psychohistory

Seldon's Assumptions

Hari Seldon charted the future history of mankind after the fall of the Galactic Empire using Psychohistory.  This became known as Seldon's Plan.   But, in order for his mathematics to be valid, he had to make certain assumptions about the Galaxy and its inhabitants.  Those assumptions, as stated by Ebling Mis, in 301FE, are:

1. that there would be no fundamental change in human society over the thousand years of the Plan and
2. that human reactions to stimuli would remain constant.

The Assumptions are more accurately stated in the Theorems of Psychohistorical Quantitivity.
