The Centrality of Probability

This chapter deals with a topic whose importance is too often ignored with respect to Ethical Counselling: probability. Probability, indeed, is at the core of many ethical decisions encountered in the age of molecular medicine, as in the case, for example, of carrier tests or predictive and presymptomatic tests, or whenever survival rates are at issue. Thus, understanding correctly the probabilistic information is extremely important and crucial and an ethical counsellor cannot be unprovided with such knowledge.
