“How much more likely is this treatment to generate the desired outcome than the alternative treatment?”
But what are the messages? This took me quite a few months to figure out. I finally realized that the messages were conditional probabilities in one direction and likelihood ratios in the other.
Bayesian thinking:
Any Bayesian analysis begins with an initial belief, aka a prior. In our case, the prior was the initial guess we had about the location of the target ball. Then we encounter objective information, which in our case was whether the new ball landed to the left or the right of the target ball. When you combine the two it gives you the improved belief

After several tests, however, the initial probability becomes dominated by the new information, which is known as “swamping the prior”
