A new hypothesis is presented within the framework of evolutionary psychology that attempts to explain the origins of obsessive-compulsive disorder. It is suggested that obsessions and compulsions originate from the overactivity of a mental module that the majority of humans possess and has the function of generating risk scenarios without voluntary intervention. It is hypothesised that obsessional phenomena function as an off-line risk avoidance process, designed to lead to risk avoidance behaviour at a future time, thus distinguishing it from anxiety and related phenomena as on-line emotional states, designed to lead to the avoidance of immediate and direct risks. Finally, the hypothesis makes a number of specific predictions that are testable and refutable. It is contended that the present hypothesis if supported by empirical evidence could serve as a basis for future research on this important disorder.
在进化心理学的框架内提出了一种新假说，试图解释强迫症的起源。该假说认为，强迫观念和强迫行为源于大多数人类所拥有的一个心理模块的过度活跃，这个心理模块具有在没有自主干预的情况下生成风险情景的功能。据推测，强迫观念现象作为一种离线风险规避过程，旨在导致未来某个时刻的风险规避行为，从而将其与焦虑及相关现象（作为在线情绪状态，旨在导致对即时和直接风险的规避）区分开来。最后，该假说做出了一些可检验和可反驳的具体预测。有人认为，如果这一假说得到实证证据的支持，可为今后对这一重要病症的研究奠定基础。
