Via One Weird Trick For Increasing Your Willpower | Psychology Today.

Suppose you are facing a willpower challenge. For instance, suppose you are a regular drinker and you have decided that you will no longer drink every day, but will drink only on Friday evenings from now on.

If I said to you:

“There is only one way to succeed, and there are many ways to fail.”

you could probably make sense of that.

The only way to succeed is to make it all the way to Friday without having a drink. But there are many ways to fail. You could have a drink on Saturday. You could have a drink on Sunday. You could have a drink on Monday. You get the point.

But here’s the thing. I if I said to you:

“There is only one way to fail, and there are many ways to succeed.”you could probably make sense of that, too.

The only way to fail is to have an alcoholic beverage at the wrong time. But when facing temptation, there are many ways to succeed. There are many alternative activities you can do instead of drinking. You can take a bath. You can go play basketball. You can have a bottle of sparkling water. You can go for a walk. Etc.

So which is it? Is there just one way to succeed with many ways to fail? Or is there one way to fail with many ways to succeed?

The truth is, neither of those claims is true or false full stop, but each becomes true or false depending on how you tell the story — how you lump things together and split them apart.

So it’s entirely up to you how you frame your challenge.

And here’s the thing…

## Seeing many paths to success increases optimism

In Psychology, there is an effect known as the Subadditivity Effect.

The subadditivity effect is the tendency to judge probability of the whole to be less than the probabilities of the parts. Here is an example pulled from the Wikipedia page:

. . . [S]ubjects in one experiment judged the probability of death from cancer in the United States was 18 percent, the probability from heart attack was 22 percent, and the probability of death from “other natural causes” was 33 percent. Other participants judged the probability of death from a natural cause was 58 percent. Natural causes are made up of precisely cancer, heart attack, and “other natural causes,” however, the sum of the latter three probabilities was 73 percent, and not 58%. According to Tversky and Koehler (1994) this kind of result is observed consistently.

So, when we estimate our chances of success, we can do it two ways. We can consider just one success condition:

A. I will resist drinking alcohol when next tempted.

Or we can consider many success conditions:

B. I will go for a walk instead of drinking.

C. I will take a bath instead of drinking.

D. I will talk with a friend instead of drinking.

E. I will find some other activity to do instead of drinking.

Now suppose we estimate probabilities for A-E. If the subadditivity effect holds, then our estimates will bear this relationship to each other:

P(A) < P(B) + P(C) + P(D) + P(E)

For instance, we might assign probabilities like this:

P(A) = .6

P(B) = .2

P(C) = .2

P(D) = .2

P(E) = .2

So we might give ourselves a 60 percent chance of success if we consider only one success condition, but an 80 percent chance if we consider multiple success conditions.

Now it’s important that we don’t explicitly make all of the above estimates and compare them in a live situation. If we do, we might break the spell. We might notice the inequality and start revising our estimates so they add up. We don’t want that. We want to take advantage of the fact that our vague and fuzzy probability judgments will be higher if we don’t look at things too closely.

What we’re looking for here is a way to increase our optimism. And to do that it’s sufficient to take our single success condition and break it into multiple success conditions, while doing the opposite with our conditions for failure.

And the reason we want to increase our optimism is because . . .

## Increasing optimism increases willpower

You might be tempted to protest that using this tactic will produce false optimism, that we’re tricking ourselves into being more optimistic than we objectively should be. But the thing about optimistic probability judgments is that, when you mix them with willpower, they can become self-fulfilling prophecies.

And that’s not just positive thinking mumbo-jumbo. It’s game theory.George Ainslie showed us in

Breakdown of Willhow our tendency to overcome a temptation at one point in time depends on how likely we think it is that we will also overcome similar temptations in the future.If we think it more likely that we will overcome those temptations in the future, then we will be more likely to overcome the temptation now.

I explain this dynamic in much more detail here: Willpower and Game Theory.

## What Now?

So what’s the bottom line here?

Well, if you want your willpower to be stronger, it will help if you raise your expectation of success. If you want to raise your expectation of success, you can take advantage of the Subadditivity Effect for probability judgments. And that means you should frame your challenge so there is just one way to fail, and there are many ways to succeed.

So go ahead, pick your most pressing willpower challenge. Remind yourself that there is only one way to fail. And then ask yourself, “What are all the ways I can succeed?” See what you come up with.
