Sociology is full of chaotic systems, so slight deviations in the premises can have wide effects on the outcome of the system you are describing. I would replace your cow analogy with a 2-pendulum analogy. Depending on the nuances of what is being observed, a small change in the inputs of your system can create dramatically different behaviors. It's important to account for how you define your initial conditions and variables so that you don't end up with a model that matches early in a simulation but ultimately diverges into something that looks nothing like what can be observed in the world.
