Remember your commute to work today? How about last night's meal with family, friends, or TV? Can you also think about the upcoming conference call, team meeting, or weekend family outing you are planning? Doing these things is engaging in the process of chronesthesia, a term for mental time travel coined by the fascinating neuroloscientist, Endel Tulving.
What's fascinating about thinking about the future is that it cannot be done without thinking about the past. Individuals who have lost certain episodic memory abilities (thinking about the past) due to injury or disease cannot imagine themselves in the future. But to what extend is imaging the future related to remembering the past?
There are many studies that link the two separate, but important mental circuits that allow us to think about the future. One of them was recently conducted by Donna Rose Addis, Alana T. Wong, and Daniel Schacter. They wanted to know how tightly connected the process of remembering the past was to constructing and elaborating upon the future.
They asked test subjects to think about past events and watch what parts of their brain were used. They asked test subjects to imagine the future one week ahead, one year ahead, and 5 to 10 years ahead. They watched which parts of the brain were used.
Here's what they found. When thinking about the future, both the "remembering the past" circuits and the "imagine the future circuits" were engaged and swapped and shared information. During the constructing the future phase the future circuits were slightly more independent than during the talking about the future phase. During both processes it was apparent from this study, and many others, that there is no way to consider the future without access to the past. Especially when it comes to talking about the future. In fact these researchers concluded that, "future thinking is indeed an important, if not the primary, function of the episodic system."
This means these researchers see "remembering the future" as the reason we have the ability to remember the past, rather than the other way around.
Leaders who only speak of the future without mentioning the context of the past open themselves to misinterpretation. We cannot think about the future without a context that includes the past and present. When leaders leave this portion of context out, their audience will by necessity have to fill in the blanks, which means they may consider different, even irrelevant, portions of the past and thus interpret the leader's message in a different way than intended.
Joseph LeDoux, another famous neuroscientist, once wrote, "One of the main jobs of consciousness is to keep our life tied together in a coherent story, a self-concept. It does that by generating explanations of behavior based upon our self-image, memories of the past, expectations of the future, the present social situation, and the physical environment in which the behavior is produced."
The past is prologue. Even if you only talk about the future, you can't do it without consulting your past.
