Brainstorming: Effects of Quantity Instructions and Time Pressure (with Joerg Dietz)
We are designing a study on brainstorming. Typical brainstorming instructions require the generation of as many alternatives as possible in a given time. The take-the-first heuristics, however, implies that earlier generated ideas might be of higher quality. In a laboratory experiment, we plan to manipulate the number of alternatives that participants have to generate (e.g., 5 ideas versus as many ideas as possible). In addition, we also manipulate the time that participants have for brainstorming (e.g., 5 minutes versus 15 minutes). Participants then generate ideas, from which they have to choose the most feasible, the most creative, and their favorite idea. Subsequently, trained raters score the generated alternatives on their feasibility and their creativeness. We invite the audience to provide feedback on the basic idea and the research design including the potential use of incentives.
