How and Why Theories Matter: A Comment on Felin and Foss (2009)
评论指出理论能影响行为甚至自我实现，需满足人们知晓、能按理论选择、社会安排被改变、支持者有权力实施等条件，对经济学等社会科学理论检验有启示。
Theories matter because they affect behavior and can, under certain circumstances, become self-fulfilling. For a theory to become self-fulfilling, people must be aware of the theory and have the ability to make choices according to its dictates, social and physical arrangements are altered on the basis of the theory's prescriptions, and the proponents have the power to implement social arrangements consistent with the theory. Economics and other social science theories often fulfill these conditions, with implications not only for the work of scholars, but also for how we think about testing theories that can change the world they describe.
