Futures thinking involves reflecting and reasoning about time. Many types of time exist; examples include clock time, emotional time, mental time, quality time, and compressed time. There is linear time, circular time, seasonal time, developmental time, and planning time. There is no time, found time, and sacred time. Futures thinking and planning requires skills in understanding types of time and engaging in reflective time-shifting. Reflective time-shifting is the ability to experience a specific moment and analyze the thoughts, feelings, and beliefs associated with experiences in that context and moment. Reflective time-shifting involves mental imagination skills and allows a person to visit past personal experiences and reframe the situations or experiences through hindsight. Time-shifting supports a change in perceptions and enables a person to imagine what it is like to step inside someone else's shoes. Reflective time-shifting enables a person to run scenarios in his or her head about alternative courses of action. Choices in feeling and behaving are by-products of reflective time-shifting.
