Tools for innovative thinking in epidemiology.

Innovation is the engine of scientific progress. Concern has been raised by the National Academies of Science about how well America is sustaining its "creative ecosystem." In this commentary, the author argues that we can all improve our ability to think innovatively through instruction and practice. The author presents a series of tools that are currently being taught in a curriculum developed at the University of Texas, based on earlier evidence-based creativity training programs. The tools are these: 1) finding the right question; 2) enhancing observation; 3) using analogies; 4) juggling induction and deduction; 5) changing your point of view; 6) broadening the perspective; 7) dissecting the problem; 8) leveraging serendipity and reversal; 9) reorganization and combination of ideas; 10) getting the most out of groups; and 11) breaking out of habitual expectations and frames. Each tool is explained using examples from science and public health. It is likely that each of us will identify with and agree with the usefulness of one or two of the tools described. Broader mastery of many of these tools, particularly when used in combination, has provided our students with a powerful device for enhancing innovation.
