The collective coordination of distributed tasks in a complex system can be represented as decision dynamics on a graph. For the case of social differentiation tasks, experimental studies on human subject networks demonstrated that shortcuts in small-world networks can speed up the finding of global solutions. Using a computational model, we illustrate that this is not always true: Depending on the actors' reasoning and the length of the added links, shortcuts can serve as topological enhancers that speed up the finding of a solution, but also as topological insulators that make the network more difficult to solve. Our findings have implications for situations where in distributed decision systems regional solutions emerge which are globally incompatible such as e.g. known from the emergence of standards.
