Today, wandering minds. The University of Houston’s College of Engineering presents
this series about the machines that make our civilization run, and the
people whose ingenuity created them.
Matthew Killingsworth trained in engineering and economics.
But, at this writing, he’s studying psychology at Harvard. Killingsworth came to realize
that, one way or another, the end of all our activity is the goal of happiness.
But how do we get there?
So he and his advisor, Daniel Gilbert, are doing an interesting study: They’ve created an
App for the iPhone. It lets them query thousands of people all over the world, at random
times, with the questions: “What are you doing?” and “How do you feel?”
Some results might be expected. Others are disquieting. Most of our commonplace
activities show only modest spread. The less happy ones include working, commuting,
grooming. The happier ones are eating, praying or meditating, walking, listening to
music. Conversation and exercise are fairly happy activities. Only two activities are
dramatic extremes: Making love is a very happy thing to do. Unpleasant mind-wandering
makes us miserably unhappy.

So they looked closely at mind-wandering — which is something I promote on
this program as absolutely essential to creative thinking. They identify three kinds
of mind-wandering — pleasant, neutral, and unpleasant. Neutral mind-wandering
leaves people slightly below the average happiness. Pleasant mind-wandering and
not-mind-wandering are each just slightly above average. But negative mind-wandering
is a very bad place to go.
So let’s look at mind-wandering. First of all, woolgathering is almost always linked
to something else we’re doing — riding, walking, working. I recall my Army basic
training — marching, standing, tired and aching. I would escape by reconstructing
the voice lines of entire Byrd masses in my head. I combined pleasant mind-wandering
with listening to music.
But most mind-wandering is less fun. They write: “The human mind is a wandering
mind, and a wandering mind is an unhappy mind. The ability to think about what is
not happening is a cognitive achievement that comes at an emotional cost.”
Yet that “ability to think about what is not happening” is exactly what inventors
do. They think not about what is, but what could be. We must let our
minds wander in that way if we hope to invent. So I go back to another small
positive item in Killingsworth’s and Gilbert’s chart — to meditation.
That lies very close to the kind of mind-wandering that the Romantic poets endorsed
for creative invention. They called it reverie — the half-waking, half-sleeping
state where we finally free our minds from all its constraints. Invention requires
the ability to go back and forth between unstructured woolgathering and focused
construction of some new thing that has not yet happened.
And the emotional cost? Well invention bounces between neutral and pleasant mind-wandering.
Its net cost is small for something that occasionally yields such a huge payoff in the coin of
self-fulfillment.
