ABSTRACT
Osborn (1953) advocated the virtue of ‘deferment of judgment’ as an aid to creativity. Later work at Buffalo in the United States by Parnes (1963) supported Osborn’s claims that through the deferment of judgement principle, more and more good ideas could be produced in unit time. Osborn had four basic rules for brainstorming: 1 Criticism is not permitted-adverse judgement of ideas must be with-
held. 2 Free-wheeling is welcome-the wilder the idea the better. One should
not be afraid to say anything that comes into one’s mind. This complete freedom stimulates more and better ideas.
