Psychohistory is a fictional term first described in
Isaak Asimov's classic novel Foundation.
Psychohistory is a branch of mathematics which deals with the reactions of human conglomerates to fixed social and economic stimuli.
In a nutshell it's the science that can predict the future.
The greatest psychohistorian of all time was
Hari Seldon.
"I quite understand that psychohistory is a statistical
science and cannot
predict the future of a single man with any accuracy."
