Abstract : The investigation dealt with the problem of biorhythmic criticality and its influence on human error and accidents, based on data from 4346 naval aircraft mishaps in the Fiscal Years 1968-1973. Observed occurrences of mishaps were computed under different aspects and compared against expected occurrences, obtained from a mathematical model. The findings of the study supported the relativity-idea in the theory of biorhythms: critical states of the three biorhythmic cycles have different effects on groups of people with different characteristics. For pilots, the study revealed no significant influence from biorhythms by straightforward application of critical days, as observed in previous research. (Modified author abstract)
