The futures wheel is a graphical method for visualizing direct and indirect consequences of a change or development. It was created in 1971 to help organize thoughts about future trends and impacts in a structured way. To create a futures wheel, an issue is defined and an event selected. Participants then identify direct, second-order, and third-order consequences in successive steps to map interrelationships and uncover unintended impacts. While it adds rigor over linear thinking, futures wheels risk becoming too complex and reflecting the biases of its creators without a diverse set of perspectives.
