In a desire to account for experimental evidence that is said to indicate that human reasoning is subject to errors and biases, some scholars have championed dual process theories of reasoning. These scholars have attempted to resolve the dual processes interaction problem by proposing either additional processes or one system dominating the other. Utilising modularity theory, this article asserts that human reasoning consists of a multitude of modules that interact via dynamical emergent processes based on information input and output requirements. The proposed solution combines research from modularity and emergence theories.
