When Aaron Beck invented cognitive therapy he prescribed
homework exercises that would help depressed patients restore some balance to
their thinking.
It was better than introspection and turned out to be as
good as Prozac.
Beck told his patients to write down a depressive thought—like
“I never get anything right”—and to add three facts that tend to prove the
thought correct and three thoughts that tend to disprove it.
To the extent that these exercises, performed repeatedly,
worked, they did so because they replaced pessimism with balance. They offered
a place for more optimistic thinking but they did not replace unalloyed
pessimism with unalloyed optimism.
I have made the point before, and have made it often. It is
worth making again because some cognitive therapists believe that positive
thinking, aka happy thought, is enough.
Gabriele Oettingen explains in The New York Times:
MANY
people think that the key to success is to cultivate and doggedly maintain an
optimistic outlook. This belief in the power of positive thinking, expressed
with varying degrees of sophistication, informs everything from affirmative pop
anthems like Katy Perry’s “Roar” to the Mayo Clinic’s suggestion that you may
be able to improve your health by eliminating “negative self-talk.”
But the
truth is that positive thinking often hinders us. More than two decades ago, I
conducted a
study in which I presented women enrolled in a weight-reduction
program with several short, open-ended scenarios about future events — and
asked them to imagine how they would fare in each one. Some of these scenarios
asked the women to imagine that they had successfully completed the program;
others asked them to imagine situations in which they were tempted to cheat on
their diets. I then asked the women to rate how positive or negative their
resulting thoughts and images were.
A year
later, I checked in on these women. The results were striking: The more
positively women had imagined themselves in these scenarios, the fewer pounds they had lost.
If positive thinking means filling your mind with fantasies
of success, it does not work very well. Apparently, the good feeling that
accompanies the fantasy demotivates people. Or else, they might believe that with the right mental attitude the rest will follow naturally.
Proponents of happy thought do not seem to recognize that
people need to work to achieve their goals. Happy thought without a plan does
not work.
To balance happy thought with work, Oettigen and her
colleagues ask their subjects to imagine the obstacles that will stand in the
way of achievement.
Beyond their ability to see themselves succeeding, they would set about making a plan for how they were going to overcome the obstacles to success.
Almost by definition, work means expending effort to overcome
obstacles.
Moreover, she adds, your wishes must be realistically
attainable. You cannot use happy thought, even accompanied by hard work, to
make yourself into Charles Barkley.
In Oettingen’s words:
Some
critics of positive thinking have advised people to discard all happy talk and
“get real” by dwelling on the challenges or obstacles. But this is too extreme
a correction. Studies have shown that this strategy doesn’t work any better
than entertaining positive fantasies.
What
does work better is a hybrid approach that combines positive thinking with “realism.”
Here’s how it works. Think of a wish. For a few minutes, imagine the wish
coming true, letting your mind wander and drift where it will. Then shift
gears. Spend a few more minutes imagining the obstacles that stand in the way
of realizing your wish.
This
simple process, which my colleagues and I call “mental contrasting,” has
produced powerful results in laboratory experiments. When participants have
performed mental contrasting with reasonable, potentially attainable wishes,
they have come away more energized and achieved better results compared with
participants who either positively fantasized or dwelt on the obstacles.
When
participants have performed mental contrasting with wishes that are not
reasonable or attainable, they have disengaged more from these wishes. Mental
contrasting spurs us on when it makes sense to pursue a wish, and lets us
abandon wishes more readily when it doesn’t, so that we can go after other,
more reasonable ambitions.
Again, Aaron Beck’s homework exercises introduced more than balanced judgment; they required work. When you are depressed and are persuaded that you are worthless, you will need to expend some energy and to overcome some obstacles to find any reason to think otherwise.
By definition, homework is work. A
patient who overcomes depression by performing these exercises has worked to defeat the mental obstacles that have been preventing him
from succeeding.
