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.

I do not use airplanes. They strike me as unsporting. You can have an automobile accident-and survive. You can be on a sinking ship-and survive. You can be in an earthquake, fire, volcanic eruption, tornado, what you will-and survive. But if your plane crashes, you do not survive. And I say the heck with it.
