Abstract
This paper shows cultural and societal background, where the number of young men, who are highly aspired to science and technology, declines. The purpose of the article is to investigate the Ortega's hypothesis that a progress of scientific and technological civilization decreases the number of young men who have high aspiration for science and technology, and to clarify the mechanisms that yield such phenomenon. The Ortega's hypothesis is formulated into a positive model, which describes associations between science/technology and culture/society. And, in order to examine the hypothesis, the association analysis of the opinion surveys, such as loglinear model, are applied. The analysis describes that the hypothesis is consistent with the present situation in Japan. Further, the results of extrapolatory simulations based on the short-term associations are consistent to the Ortega's superlong-term hypothesis. The results of these analyses show the fact that the paradoxical phenomenon, pointed out by Ortega, necessarily occurs.
