Human processes differ from rational processes in their outcome
A process is rational if it always does the right thing based on the current information, given an ideal performance measure
In short, rational processes go by the book and assume that the book is actually correct
Human processes involve instinct, intuition, and other variables that don’t necessarily reflect the book and may not even consider the existing data
As an example, the rational way to drive a car is to always follow the laws
(Likewise, pedestrian crossing signs vary depending on the country with differing appearances of a person crossing the street
) However, traffic isn’t rational; if you follow the laws precisely, you end up stuck somewhere because other drivers aren’t following the laws precisely
To be successful, a self‑riving car must therefore act humanly, rather than rationally
