Dialectical Inquiry in Strategic Planning: A Case of Premature Acceptance
多项实地研究支持辩证探究有助于战略决策，但证据不确凿，另有研究认为魔鬼代言人方法可能更优。两者根本区别在于辩证探究需指定替代行动方案，而战略假设分析的好处可能无需此步骤即可实现。
Evidence from several field studies supports the claim that dialectical inquiry aids strategic decision making. This evidence is not conclusive, however, and findings from other studies have indicated that a devil's advocate approach may be superior. A fundamental difference between the two is that dialectical inquiry requires specification of an alternative course of action. It is possible that the benefits of strategic assumptions analysis can be realized without this specification—i.e., through a devil's advocate approach.
