Good versus creative solutions: A comparison of brainstorming, hierarchical, and perspective-changing heuristics

It is not clear what heuristics are best for generating solutions to ill-st ructured problems. This research examined 3 heuristics (brainstorming, the hierarchical technique, and changing perspectives) to determine which produ ced the most solutions, the best solutions, and the most creative solutions . Ninety-two participants generated as many solutions as they could to I il l-structured problem concerning a drug-dealing roommate. Participants were then randomly assigned to I kind of training. After training, participants returned to generate solutions to the roommate problem. Results indicate th at the hierarchical method produced the most solutions and the highest prop ortion of participants who judged their best solution as occurring after tr aining. Those trained in brainstorming were most likely to judge their most creative solution as occurring after training. The changing perspectives t echnique was found to be relatively less helpful in terms of best and most creative solutions.
