The best New Year's resolutions are positive resolutions


As we approach a new year, it is common for us to take stock of our lives and think about things that we’d like to do differently in the coming year.  Often, the resolutions we think about are negative resolutions.  That is, we have some behavior that we currently perform that we’d like to stop.  It might be quitting smoking, or eating less junk food, stopping drinking or drugs, or even cutting back on bad language.

Unfortunately, if we are thinking about these kinds of resolutions, it is probably not for the first time.  Mark Twain is supposed to have said that quitting smoking is one of the easiest things he ever did, he has done it thousands of times. 

There are many reasons why stopping these behaviors are difficult, and I have written about some of these difficulties in past entries.  Here, I want to focus on the form of the resolution itself.

I called these resolutions “negative resolutions” because they focus on a behavior to be stopped.  Often, this behavior is already a habit, and so it is strongly driven by the environment.  That is, parts of your environment already suggest the behavior to you.  Just drinking a cup of coffee may promote the desire to smoke.  Walking through the kitchen may increase the urge to eat.

In order to try to stop a behavior, you have to think about that behavior consciously.  That is, if you want to cut down on your eating, you must exert effort to think about what you are doing.  To watch yourself to make sure that you don’t eat too much.

Research by Peter Herman, Janet Polivy and their colleagues suggests that people who are actively trying to diet become “restrained eaters.”  Restrained eaters are people who are thinking about their diet and about restricting the amount of food they eat.  The problem with being a restrained eater is that it creates a paradox.  You want to stop eating, so you have to think about your eating behavior.  The more you think about eating, the more that concepts related to food and eating stay active.  As I have discussed in previous posts, when a concept is active, it is easier for people to perform actions relating to that concept. 

So, focusing on reducing your eating can actually make it harder for you to eat less.  The same is true for any negative resolution.  Thinking about not smoking or drinking or cursing will activate related concepts, which will make it easier to smoke, drink, or curse. 

In the end, the problem lies with the resolution itself.  You cannot replace something with nothing.  The habit system will still have connections between the environment and your behavior, and so it will continue to suggest the behavior you are trying to stop.  As a result, you will have to continue thinking about stopping the behavior. 

So, rather than making negative resolutions, make positive ones.  Do not resolve to stop smoking, resolve to start exercising.  If you really start an exercise program, your smoking will get in the way, and you will have a reason to stop.  Do not resolve to eat less, resolve to eat differently.  Cut red meat out of your diet, and start eating other foods.  With the number of really good meat substitutes on the market now, it is easy to replace high-fat foods with low-fat foods without sacrificing taste.

If you focus your energies on positive resolutions, then you will not suffer the paradox of negative resolutions.  If you start exercising, you will not be consciously thinking about smoking.  You will have removed one source of failure in your resolutions.

So in the coming year, think positive!

Patience may be a virtue, but it is also really hard.


My dog eats two meals a day, one in the morning and one in the evening.  She is trained to sit until the bowl is on the floor before she leaps to start eating.  She does it, but it is a real challenge.  She gets excited from the moment that she sees the food being put in the bowl, and it requires a tremendous act of will to keep from leaping to the bowl before it is set down.

This daily routine has an important lesson for behavior change.

Animals (like my dog) have a hard time waiting for a good thing.  Even if I set things up so that she would get more food in a few minutes if she could wait, she would have a lot of trouble waiting.  The idea that something now is more valuable than even more later is called delay discounting.  Animals of all types have a high discount rate.  That is, they have a hard time being patient.  They would rather have something now than more of it later.  This is true, even when the delay is just a few seconds or a minute. 

So, what does this have to do with you?

As humans, we pride ourselves on having some patience.  The dog can hardly wait to snap at her meal, but we can wait until the entire table is served before digging in. 

That pride may be misplaced.

A study by Koji Jimura, Joel Myerson, Joseph Hilgard, Todd Braver, and Leonard Green in the December, 2009 issue of Psychonomic Bulletin and Review makes the point that we’re a lot more like animals than we’d like to think.  In their study, they brought thirsty people to the lab and gave them choices between a small amount of a drink of their choice immediately (juice or water) or a larger amount some time in the near future.  The wait times ranged between 5 seconds and a minute.  The people in the study were told that a new choice would be given at a fixed interval, so they would not get more chances to make choices if they always chose the immediate option.

People who selected the immediate drink, were given a chance to drink right away.  Those who selected the larger drink had to sit through the delay period before getting the chance to drink. 

People in this study showed a very high rate of delay discounting, just as animals do.  That is, unless people were offered a lot more juice to wait, they tended to select the immediate drink.

What does this mean for you?

These results make clear that we are not that much different than other animals in our ability to delay our rewards.  If there is a small reward in front of us now, it is hard to give it up for the promise of a bigger reward in the future.  Short-term temptations put a strong pull on us.

So, how do you succeed in changing your behavior? 

If you are trying to lose weight and you have the choice between a slice of pie now or being thin in the future, you are almost always going to take the piece of pie now.  If you are trying to stop smoking, the cigarette being offered to you is going to be much more attractive to you than your future good health. 

You have to remove the immediate option from your environment.  If you want to lose weight, don’t look at the dessert menu, and don’t keep sweets at home.  If you want to stop smoking, don’t stand outside with your friends while they have a cigarette. 

Don’t put yourself in the position of having to protect big rewards in the future from the small ones in your path right now.
