Based on 1990 SDR Article. Control systems act to make their own input match internal standards or reference signals. Competent control systems create illusions of stimulus response causality. Stimulus-response theory can approximate the relationship between disturbance and action, but it can't predict the consequences of behavior. These consequences are maintained despite disturbances.

This Loan Cost Model is the second in the series. It takes into account the potential cost of student loans in the case that the student does not manage to graduate college or does not succeed in their career.

OK, we have a problem. Yet do we really know what the problem is? There is a also a video for this insight which is a component of the Effective Problem Solving Learning Program.

This common archetype of systems that include relapse or recidivism allows exploration of the unintended effects of increasing upstream capacity and swamping downstream capacity. The increase in the relapse rate eventually returns to swamp upstream capacity as well.

Based on a sound realization of reality we need an effective approach to dealing with situations which promotes the requisite understanding to develop a strategy that deals appropriately with the situation. A strategy which also is explicitly designed to minimize unintended consequences and puts in place responses to them should they arise.

All the following have a common characteristic.
