Mental models are a filter that this information must pass through, as shown below.
Mental models are subtle but powerful.
Subtle, because we usually are unaware of their effect. Powerful, because they determine what we pay attention to, and therefore what we do. And because we see what our mental models permit us to see, we do what our mental models permit us to do. These projections are not about change and therefore are not planning as defined in this set of documents. This does not mean that all mental models will be changed by a planning procedure.
