Precisely...lack of predictability.
So.. you are saying that there is predictability about the unpredictability...interesting.

The Physics of Chance and Necessity,Spring Semester, 1998
Course Description:
The course will introduce students to a wide range of important and beautiful concepts of physics, by emphasizing the role of probability and statistics in both classical and quantum physics. Early in this century, Einstein rejected the probabilistic interpretation of quantum physics with his famous statement: "I refuse to believe that God plays dice."Today, however, there is a general realization that while the universe is a lawful place, it is nonetheless a place in which chance plays a major role. Even in the domain of Newtonian physics, where determinism once was not doubted, the idea of a deterministic universe has had to be modified radically, and the behavior of many systems that are governed by Newtonian physics cannot be predicted accurately. By focusing on the theme of "chance", this course leads the student naturally through a very diverse range of topics.
