Basic Considerations for Argument and Evidence Evaluation

This post will be brief. I just want to consider some useful mental tools for evaluating reasons and evidence. Let's consider a mathematical derivation of missing evidence based on a Bayesian framework. What we want to do is show that rationally, if you cannot find evidence for some claim after a thorough search, then it is likely the event did not occur. Definitions Let  X X  be an arbitrary event, or combination of arbitrary events. Let  \neg X ¬ X  denote "NOT X" Let  E E  represent the existence of a set of positive evidences that would indicate the reality of X Let  \neg E ¬ E  denote "NOT E", or the total absence of positive evidence. Let  P(x) P ( x )  denote the probability of event  X X . Let  P(X \mid E) P ( X ∣ E )  denote the conditional probability of X  given  E By definition, this is the joint probability of X AND E divided by the probability of E: P(X \mid E) = \frac{P(X \cap E)}{P(E)} P ( X ∣ E ) = P ( E ) P ( X ∩ E ) ​ Let X be the intersection
