problem solving, system understanding; When we replace our problem solving paradigm with a system-understanding paradigm things go much better...
Such a great question! One that requires a bit of prerequisite terminology. The DSRP and VMCL "building blocks" are as you say simple even though they belie the emergent outcomes of complex systems (cognitive complexity and organization, respectively). In both cases this is because these systems (cognitive complexity and organization) are complex adaptive systems (CAS).
The question you are asking is a slightly more complex one. When USING a CAS as a tool to UNDERSTAND another CAS, can we expect solution or understanding to ALSO be simple.
If the system being studied is, in fact, a CAS, then yes. But if it is a different type of system, then perhaps not. (See some other types of systems here https://help.cabreraresearch.org/effective-complexity ).
The other question that is embedded is, will (1) the system (under study) BE SIMPLE or (2) will the system be DRIVEN by SIMPLE RULES? IF you are analyzing a CAS (which all social systems will be, for example) then the answer is #2. Iow, the system itself will be complex, because it is. But that complexity will be the emergent property of simple rules.
As an example, a team of our students recently analyzed such a system in the Galapagos and came up with recommendations which are simple. But the system itself is massively complex. We call this "CAS-based analysis."

So, simple answer is, if it is a CAS then the system itself will be complex, but your analysis would benefit from seeking to discover the underlying simple rules.
