What is post-normal science? What are the reasons for, and consequences of, encountering it in one’s professional life? Here I share my own experience of readings, practices and discussions with the fathers, supporters and detractors of PNS. After a short description of PNS and of my own experience with it, I review some common criticism levelled to PNS from different authors and conclude reflecting on how PNS—difficult to explain and translate into formulae or checklists—provides its practitioners with useful keys to open relevant doors to understanding, and might be especially suited to face the present intersecting crises befalling the use of science for policy.

什么是后正常科学？在职业生涯中遇到这种情况的原因和后果是什么？在这里，我与 PNS 之父、支持者和反对者分享我自己的阅读、实践和讨论的经验。在对 PNS 以及我自己的使用体验进行简短描述之后，我回顾了不同作者对 PNS 的一些常见批评，并总结反思了 PNS（难以解释并转化为公式或清单）如何为其从业者提供了打开大门的有用钥匙。理解的相关大门，可能特别适合面对目前将科学用于政策而发生的交叉危机。
