An Addiction structure is the same as the Shifting the Burden structure though with the annoying aspect that one becomes addicted to the side effect ensuring that Fundamental Solution won't get implemented and the Symptomatic Solution will be applied repeatedly, and likely with greater frequency. There is a also a video
for this insight which is a component of the Systems Thinking World Kumu e-Learning Environment
This structure is the same as the Shifting the Burden structure though there's a slight twist in the behavior. Employing the [symptomatic solution] doesn't just produce a side affect, it produces an [addiction] which can actually make the problem worse.
There have been two changes to the simulation simulation structure; 1) the [fundamental action] is now bi-directional; 2) the [Fundamental Solution] is allowed to go negative. The implications of this will be seen shortly in the simulation.
This is about where we left things with Shifting the Burden. A little worse off because of the changes made to the structure, though not very much, or so it would seem!!! But what really happens in the longer term?
If you run the simulation with the same parameter values for Simulation Length = 20 the vicious implications of R3 become very apparent.
Strategy: Steps are; 1) realizing the nature of the addiction; 2) deciding to stop the insanity; 3) find a support system to help. Seldom does one escape form this situation on their own.
I would encourage you to access this model and run numerous simulations with different values for the parameters until you begin to get a sense of the implications of the relations in this structure.
