❚❘ BRAINSTORMING In 1938, Alex F. Osborn, an advertising executive, invented the process of “organized ideation” in a company he headed. The early participants referred to their attempts as “brainstorm sessions,” in the sense that they were using the brain to storm a problem. The term brainstorming has now become the accepted way of referring to group attempts to solve specific problems or develop new ideas by amassing spontaneous, unrestrained contributions by members. Osborn (1979) credited the origin of the process to Hindu teachers in India, who have used the method of Prai- (outside yourself) Barshana (question) for over 400 years. During such a session, there is no discussion or criticism; evaluation of ideas takes place at later meetings of the same group. Brainstorming can be used to generate possible solutions for simple problems, but it is unrealistic to expect it to accomplish most problem-solving or planning tasks. The technique is of value as part of a larger effort that includes individual generation of information and ideas and subsequent compilation, evaluation, and selection. Brainstorming can be used to generate components of a plan, process, solution, or approach and to produce checklists. Osborn (1948) saw the value in a session that was designed solely to produce a list of ideas that could be used later in problem solving or other creative processes. The key to the success of the process is that no evaluation or judgment is made of the ideas as they are being generated. Because of this, creativity is not stifled, it is increased. The objective is to generate as many ideas related to the specific topic or question as possible. Studies have shown that the ideas generated by the group tend to get better as the group gets warmed up. The value of the process is that more good ideas are produced in less time than would be produced in a typical meeting or conference. Discussion, evaluation, and selection occur at a later time. One of the reasons why brainstorming works is that ideas generate further ideas through the power of association—a process that has been called “hitch-hiking” or “piggybacking.” Also, the technique of “free association” is more powerful when one is working in a group than when one is working alone. Reinforcement is another factor that leads to increased creativity. In the idea-generation phase of brainstorming, all suggestions are rewarded by being received and listed—a positive reinforcement. Nothing is criticized; there is no negative reinforcement.
