Garbage Can in the Lab

We develop an experimental setting where the assumptions and predictions of the garbage can model can be tested. A careful recon- struction of the original simulation model let us select parameters that leave room for potential variations in individual behavior. Our experi- mental design replicates these parameters and thereby facilitates comparison of human behavior with the original model. We find that the majority strategy of human subjects is consistent with the original model, but exhibits some behavioral diversity. Human subjects exhibit fluid diverse behaviors that improve coordination in the face of uncertainty, but hinder collective learning that can improve group performance
