I only have a tenuous grasp of Bayes' Theorem. I get the concept. But I haven't internalized it enough to make use of it in real world situations. I'm trying to decide whether it really makes sense for me to put in the effort to understanding it when I could be putting that effort into other things. I'm curious what examples people here have of making use of it in a concrete way in real life? (In particular, real life examples that weren't contingent on you being a scientist)
My roommate and I use the intuitions behind Bayesian Search Theory explicitly when we are looking for something in the house or notice that the other is, though we do not use the math. Briefly: if you've already searched the kitchen thoroughly, it's probably somewhere else (or under something absurd) even though you remember putting it down in the kitchen.
I use the intuitions in hidden Bayes-structure at work quite a lot as a framework for thinking about our projects. Supposedly this product is improving users' lives - it's essentially making decisions about what to show or not show the user, what to do or not do - there's some average behavior that we decide it shouldn't always do - BAM find the evidence that the product we ship uses to update its priors and act differently than average, then ask whether that evidence is easily grown, efficiently collected, just-plain-wrong, etc. etc.
I find I use the intuitions behind Bayes' Theorem much more often than the math. And I'm not sure I act differently by thinking with that framework so much as come to the right question faster (which yes, is acting differently).
