Raw Ideas in the Fuzzy Front End: Verbosity Increases Perceived Creativity

Abstract

At the “fuzzy front end” of an innovation process, organizations typically consider dozens, or even hundreds, of raw ideas. Selecting the best ones is a double challenge: evaluating so many ideas is a large undertaking, and the ideas in their raw form permit only noisy evaluations. In this paper, we demonstrate a further challenge to that large-scale evaluation of raw ideas. We show that verbosity raises the evaluation of ideas, that is, ideas expressed in more words are rated higher. This relationship is especially pronounced for ratings of creativity. Theory tells us that the effect of length on creativity is compounded because length cues both components of creativity—novelty and usefulness. We demonstrate how effort in reading (disfluency) and perceptions of complexity work together to explain the relationship between length and creativity. Our findings provide simple but important new directives for improving the use of crowdsourcing in the practice and study of innovation: either standardize the length of the ideas or control for length in their evaluation. Overall, we urge care with using measures of novelty or creativity when the idea descriptions vary in length.
