The driving condition for the complete edifice of all probability theory is one single postulate: for two mutually exclusive events, A and B (where mutually exclusivity implies that both events cannot occur at the same time), P (A or B) = P (A) + P (B). As a final beginning definition, we say that two events are independent whenever the probability of the joint event, P (A and B), factors as the product of the individual probabilities, P (A)P (B). The idea of statistical independence and the factoring of the joint event probability immediately provide a formal tool for understanding a number of historical miscarriages of justice.
These results derived from the original of B being facilitative for A, P (A|B) > P (A), ¯ being inhibitive of A, or as A¯ being could have been restated as B inhibitive of B. 7 More likely, we are given problems characterized by fallible data, and subject to other types of probabilistic processes. For example, even though 32 A Statistical Guide for the Ethically Perplexed someone may have some genetic marker that has a greater presence in individuals who have developed some disease (for example, breast cancer and the BRAC1 gene), it is not typically an unadulterated causal necessity.
Whether using a test that is wrong 95% of the time is worth doing is, at least partially, an ethical question, because if we decide that it isn’t worth doing, what is the fate of the 5% or so of women who are correctly diagnosed? 5 billion to the overall diagnostic bill. 1: A tree diagram using calculated probabilities to obtain the positive predictive value for mammograms. 047 36 A Statistical Guide for the Ethically Perplexed 180,000 tumors? That is about $39,000/tumor detected. And, not to put too fine a point on it, biopsies have their own risks: 1% yield staph infections, and they too have false positives, implying that some women end up being treated for nonexistent cancers.
