The relationship between loyalty to rules and the creativity that attempts to improve those same rules was examined among Norwegian army officers deployed in international operations. Today's army officers are faced with rapidly changing work conditions and unpredictable enemies, both of which challenge and outdate rules and routines. They thus may experience that they are either guided by too few or inadequate rules, or by many rules that need to be constantly updated. Assuming that following rules is advantageous to officers, then, contrary to classical theory, it was hypothesized that officers scoring both low and high on loyalty to rules would score high on creativity. Hierarchical regression analyses revealed a significant U-shaped relationship between loyalty to rules and creativity. (Contains 2 tables and 1 figure.)
