An Adaption of the Jaynes Decision Algorithm

There are two types of decisions: given the estimated state of affairs, one decides to change oneself in a certain way (that is best suited for the given conditions); given what one is, one decides to change the state of affairs in a certain way (that is best suited for what one wants for oneself). Jaynes' approach to decision theory accounts only for the first type of decisions, the case when one is just an observer of the external world and the decision doesn't change the world. However, many decisions involve the wish to transform the external environment. To account for this we need to add an additional step in Jaynes' proposed algorithm.
