Globalization and the Rise and Fall of Cognitive Control
The scale of human interaction patterns is larger now than ever before – people regularly interact with and learn from others around the world, and we each have the ability to impact the global environment that is shared by all. The consequences of local versus global interaction - particularly for the evolution of cooperation - have been studied extensively by evolutionary game theorists for decades. Here, we use this lens to explore a new question: How does the scale of interaction affect the evolution of cognition, and in particular the use of automatic (e.g., reflexive or habitual) versus controlled (e.g., deliberative) cognitive processing? We find robust evidence of cycles of automaticity versus control, and that these dynamics are influenced by the scale of interaction. Specifically, globalized environment disfavors cognitive control; globalized direct contact can either favor or disfavor control, depending on whether controlled agents are harmed or helped by contact with automatic agents; and globalized learning phase-locks the whole population and destroys meso-scale communities of more versus less controlled agents. These results emphasize the importance of the scale of interaction for the evolution of cognition, and help shed light on challenges currently facing our species.
