When we are talking about contingencies, we should always remember that it is ultimately the nature of cognition of each subject that determines their nature, although certainly affected by the objective statistics of events.
The same situation can be the source of different contingency for different people. For an experienced skier, a snowy slope would not present a high degree of contingency. For a novice wearing ski boards for the first time, even standing still on the snow slope can be a problem.
For a patient being told that she has cancer, the life suddenly becomes full of contingencies. For the medical doctor who is treating her, the diagnosis of cancer should be accompanied with less uncertainties, based on his expertise and accumulated experience as a specialist in the field.
Thus, contingencies are sometimes very personal. In order to encounter an interesting case of contingency, one sometimes needs to actively search for it.
Appropriately presented contingency is a necessary "food" for the brain's learning process. One should always be "contingency aware" in the course of one's life, always assessing in a metacognitive process the nature of contingencies that one is currently encountering in life.
