A pattern may be seen among models from the physical, natural, and social sciences. The pattern derives from the hierarchical level of complexity of the phenomenon modeled, relative to the human modeler. Rigor decreases as models treat natural events progressively closer to the full complexity of the human. "Rigor" here is determined entirely by the conventional indicators of the scientific community; "complexity" refers to hierarchical level. This pattern of decreasing rigor is analogized to a limiting feature of formal systems: reflexivity. The scientific method of inquiry is observed to assume lawfulness in nature; lawfulness without reflexivity is suggested to be a dilemma. The gradient of rigor observed among models is suggested to be necessary, stable, and homeostatic. Consequently, reflexivity in nature is adopted as the most satisfactory metadisciplinary null hypothesis.
在物理、自然和社会科学的模型中可以看到一种模式。这种模式源于所建模现象相对于人类建模者的复杂层次水平。随着模型越来越接近人类的全部复杂性来处理自然事件，严谨性会降低。这里的“严谨性”完全由科学界的传统指标决定；“复杂性”指的是层次水平。这种严谨性降低的模式被类比为形式系统的一个极限特征：自反性。观察到科学探究方法假定自然界具有规律性；没有自反性的规律性被认为是一个困境。模型中观察到的严谨性梯度被认为是必要的、稳定的和稳态的。因此，自然界中的自反性被采纳为最令人满意的元学科零假设。
