Simplified Decision Filter Structure

This is a simpified view of the internal structure of the decision filter and serves as a brief review. The decision process involves gathering the evidence for and against each therapy – this evidence is used to estimate the “promise” of the therapy, which is the likelyhood that you will gain a significant benefit from it.

Then based on specific characteristics of the therapy and your own situation and desires you decide how promising the therapy has to be before you are willing to use it. Your basic level of skepticism is modified by these individual factors – called “cut-off modifiers” to produce a cut-off value for the particular therapy.

Then if the therapy is at least as promising as your cut-off for it you “select it” – meaning you decide to use it. If it is not, then you decide not to use it.

Of course, no one literally computes numbers to represent the promise or cut-off, but I think a rational decision means deciding if the therapy is promising enough given the evidence and other circumstances.

The next and final slide shows the full decision filter along with extensive explanation of each of its parts.
