This episode accompanies Module 12 of the course, which is about how we bring together the various sources of evidence that we've gathered.

The purpose of taking an evidence-based approach is to reduce uncertainty in our decision making, looking at likelihoods and probabilities to guide our thinking and discussions. The use of Bayes rule and Bayesian thinking are explored, so that we continue to protect ourselves from falling prey to bias (particularly confirmation bias), but that we consider alternative explanations for the evidence that we found - if our initial belief is either true or false.

The use of probabilities isn't something our brains take to easily, so there is some challenge inherent in this approach, but it is simply an extension of the overall evidence-based management approach, where we look at each type of evidence and consistently question whether it is trustworthy, robust and reliable. Once we reach the 'aggregate" stage, it's time to ask how likely is it that the claim or hypothesis we are investigating is true (or false).
