Today, I learned about a process that uses the nature of counter-example to generate new ideas. It's called "reverse brainstorming:"
Instead of asking participants to come up with great ideas for improving a process or achieving a goal, you ask them to instead brainstorm ways to absolutely undermine a process or make a goal impossible to achieve. You let all those pent-up negative thoughts bubble to the surface. This provides the group with useful information about what isn’t working. Once you know what isn’t working, of course, you have the tools you need to plan for success.According to the post, this approach works best when a group is burned out or lacking enthusiasm about a project, or when a particular process has become so established it's difficult to break out of it. It also gives group members a chance to vent their frustrations.
