“…NK model has been widely used in the agent-based models to study the complex adaptive systems (CAS) such as the organizational adaptation [38,46] and the collective problem solving [18,48,51,53]. The proposed model in this paper is a model on collective problem solving.…”

This paper’s purpose is to clarify groupthink phenomena and to assess the devil’s advocacy as a groupthink prevention measure. An agent-based model is presented to formalize group closed-mindedness and insulation in a group decision making setting. The model was validated by showing that groupthink results in the decision with low quality and the group’s inability to explore more alternatives. Besides that, the devil’s advocacy also formulated in the model. The simulation results of different conditions of the devil’s advocacy support Janis’ suggestion to utilize the devil’s advocacy to alleviate groupthink. It is also found that the utilization of devil’s advocacy depends on the group’s condition and the desired amount of conflict to produce the best decision.

“…However, different models within the NK tradition exhibit conflicting results on this question. Geisendorf (2010) summarizes the debate as between those (Dosi and Marengo 2005;Brusoni et al 2007) who find speed of evolution advantages to over-modularization and those (Levinthal 1997;Ethiraj and Levinthal 2004;Geisendorf 2010) who do not. There are also other papers which address the question which do not explicitly frame their results in terms of over-modularization (e.g.…”

“…In the economics and management literatures, several simulation studies have been carried out to analyze the conditions under which modular systems favor adaptation compared to other complex systems (Frenken et al 1999, Marengo et al 2000Ethiraj and Levinthal 2004;Dosi and Marengo 2005;Brusoni et al 2007;Rivkin and Siggelkow 2007;Ciarli et al 2008;Geisendorf 2010;McNerney et al 2011;cf Bradshaw 1992;Baldwin and Clark 2000). These studies tend to confirm the central idea that modular systems are improved by random mutation and natural selection at a faster rate than other complex systems.…”

Modularity is an important concept in evolutionary theorizing but lack of a consistent definition renders study difficult. Using the generalized NK-model of fitness landscapes, we differentiate modularity from decomposability. Modular and decomposable systems are both composed of subsystems, but in the former, these subsystems are connected via interface standards, while in the latter, subsystems are completely isolated. We derive the optimal level of modularity, which minimizes the time required to globally optimize a system, both for the case of two-layered systems and for the general case of multi-layered hierarchical systems containing modules within modules. This derivation supports the hypothesis of modularity as a mechanism to increase the speed of evolution. Our formal definition clarifies the concept of modularity and provides a framework and an analytical baseline for further research.

Within the field of economics the NK model is used for mainly two things, (1) the study of properties of different fitness landscapes themselves (e.g.…”

The working paper features an extended literature overview of the ways in which fitness landscapes have been interpreted and used in the social sciences, for which there was not enough space in the full article. The article features an in-depth philosophical discussion about the added value of the various ways in which fitness landscapes are used in the social sciences. This discussion is absent in the current working paper.
