My background is in the field of system dynamics — a modeling technique developed at MIT that applies concepts from feedback control engineering to studying social systems such as markets or the general economy.
My observation is that what we generally term as the ‘economy’ (national or world economic activity) is far, far too complex for any individual to understand or forecast simply by thinking about it. Hence, we have all of these idealogical conflicts.
Mental models are not sufficient to sort out these issues and I doubt there are currently any mathematical models that are sufficient either. Hence, we are left with arguing.
I often notice that people talk the most about what they know the least about. We must discover how to manage ourselves. Endless arguing won’t do it.
