As a bridge between system two and system one, I want to say a little bit about the Decision Support Committee. Because in many ways, the are another group of experts we have to deal with. In fact, you really can't put into place any intervention and showing out decision support without a small community of people. It could be the domain expert who knows about infectious disease, it could be the nursing expert who knows how things work in the hospital, it could be the pharmacist whose is the domain expert about medications, there's always going to be committee. So, even if you're going to go to the literature, and go to the Data Warehouse, you're always going to have data. You'll always have some notion dealing with experts. Now, the committee cares about things beyond where certainly you should. The usual framework is not the problem itself. The committee cares a bit beyond the problem itself, what we might call "meta" issues. So, they care about, why is this problem important at all? They want to know the story about this problem, because they are going to have to sell this decision support to people, and a purely system one way, people respond to stories more than they respond to cold models and decision analysis trees. So, a story, is a classic system one sort of way of dealing with information, and so you're going to have to come up with the story. So what will be acceptable is again, much more human, sort of system one sort of issue, and how to integrate with the workflow and staff. I already mentioned the nursing, the pharmacy. That sort of expertise is hard to codify in something like a tree. So, the skills of doing how are not covered in the system two thinking. So, I simply want to point out that as we get to implicit sorts of knowledge, you'll be dealing with that in the rest of the committee. I like the advice from Sigmund Freud about all this, he says, "When making a decision of minor importance, I have always found it advantageous to consider all the pros and cons". So what is pros and cons, that system one or system two? Right, it's system two. Then he goes on to say, "In vital matters, however, such as the choice of a mate or profession, the decision should come from the unconscious, from somewhere within ourselves", and that is clearly system one. So, I think it's pretty funny, that we kill ourselves to actually do decision-making but from Freud's perspective, that's great for the minor stuff but something important, you go with your gut. So, next let's talk about how to go at at that gut.
