菅家正瑞教授定年退職記念号In Honour of Prof. Masamitsu KankeThis paper reviews the concept of“working hypotheses”by Waller and Uitdewilligen(2009) in terms of four theoretical points: existence itself, ends, learning, and timing．“Working hypotheses”are derived from voice analysis based on the documents recorded at Northeast Air Defense Sector (NEADS) on the Day of the 911．According to the analysis, the contents of working hypotheses seem to have shifted not linearly but non-linearly. On the point of hypothesis shift, the NEADS staff “talked to the room”under crisis, i.e., the abnormal or coordinated hijack. Faced with non-routine, any decision-maker would be apt to seek something to refer to. That is the reason why we take four theoretical points into consideration. In order to understand the non-linear process, we insist that decision-makers should be treated heterogeneously instead of homogeneously．
