Summary of expected outcome, concepts activated and iteration process for three sample cases
Case Concepts activated Outcome
Case 1: Extremely likely to result in homelessness Criminal justice system involvement, addictions, mental illness, rental subsidy Iteration 1: homelessness = 1; all other concepts, stable. Conclusion: extremely likely to result in homelessness.
Case 2: Extremely unlikely to result in homelessness Education, mental illness, non-government organization, and income assumed to be high Iteration 1: homelessness = -1; increase in education; decrease in poverty, unemployment, and government assistance; all other concepts, stable. Iteration 2: homelessness = -1; increase in education and mental illness; decrease in crime; and all other concepts, stable. Iteration 3: homelessness = -1; increase in education, and mental illness; decrease in crime and criminal justice system involvement; all other concepts stable. Conclusion: extremely unlikely to result in homelessness.
Case 3: Uncertain likelihood of homelessness Criminal justice system involvement, addiction, family breakdown, increased income, education, and social systems network. Iteration 1: homelessness = -1; increase in addiction, criminal justice system involvement, family breakdown, income, counseling, crime, and social isolation; decrease in poverty, unemployment, and government assistance.
