Notes : The Willpower Instinct by Kelly McGonigal

1. The best way to improve your self-control is to see how and why you lose control. Knowing how you are likely to give in doesn’t, as many people fear, set yourself up for failure. It allows you to support yourself and avoid the traps that lead to willpower failures. Research shows that people who think they have the most willpower are actually the most likely to lose control when tempted.

2. Willpower is about harnessing the three powers of I will, I won’t, and I want to help you achieve your goals (and stay out of trouble).

3. In other words, when Gage lost his prefrontal cortex, he lost his will power, his won’t power, and his want power. i.e. The Preforntal Cortex is what gives us the ability to control ourselves.

4. Most of us don’t have to worry about ill-timed railroad explosions robbing us of our self-control, but we all have a little Phineas Gage in us. The prefrontal cortex is not always as reliable as we’d like. Many temporary states—like being drunk, sleep-deprived, or even just distracted—inhibit the prefrontal cortex, mimicking the brain damage that Gage sustained.

5. Some neuroscientists go so far as to say that we have one brain but two minds—or even, two people living inside our mind. There’s the version of us that acts on impulse and seeks immediate gratification, and the version of us that controls our impulses and delays gratification to protect our long-term goals. They’re both us, but we switch back and forth between these two selves. Sometimes we identify with the person who wants to lose weight, and sometimes we identify with the person who just wants the cookie.

6. Baba Shiv, a professor of marketing at the Stanford Graduate School of Business, has shown that people who are distracted are more likely to give in to temptations. For example, students trying to remember a telephone number are 50 percent more likely to choose chocolate cake over fruit at a snack cart. Distracted shoppers are more susceptible to in-store promotions, and more likely to go home with items not on their shopping lists.

7. Or you could do something a lot simpler and less painful: meditate. Neuroscientists have discovered that when you ask the brain to meditate, it gets better not just at meditating, but at a wide range of self-control skills, including attention, focus, stress management, impulse control, and selfawareness. People who meditate regularly aren’t just better at these things. Over time, their brains become finely tuned willpower machines. Regular meditators have more gray matter in the prefrontal cortex, as well as regions of the brain that support self-awareness.

8. One study found that just three hours of meditation practice led to improved attention and self-control. After eleven hours, researchers could see those changes in the brain. The new meditators had increased neural connections between regions of the brain important for staying focused, ignoring distractions, and controlling impulses. Another study found that eight weeks of daily meditation practice led to increased self-awareness in everyday life, as well as increased gray matter in corresponding areas of the brain.

9. “What was my body doing?” Science is discovering that self-control is a matter of physiology, not just psychology.

10. The good news is that you can learn to shift your physiology into that state when you need your willpower the most. You can also train the body’s capacity to stay in this state, so that when temptation strikes, your instinctive response is one of self-control.

11. While your body was getting ready to defend your life, the alarm system in your brain was busy trying to make sure that you didn’t get in the body’s way. It focused your attention and senses on the saber-toothed tiger and your surroundings, making sure no stray thoughts distracted you from the threat at hand. The alarm system also prompted a complex change in brain chemicals that inhibited your prefrontal cortex, the area of the brain in charge of impulse control. That’s right, the fight-or-flight response wants to make you more impulsive. The rational, wise, and deliberative prefrontal cortex is effectively put to sleep—the better to make sure you don’t chicken out or overthink your escape. Speaking of escape, I’d say your best bet in this situation is to start running. Now.

12. Suzanne Segerstrom, a psychologist at the University of Kentucky, studies how states of mind like stress and hope influence the body. She has found that, just like stress, self-control has a biological signature.

13. Segerstrom calls those changes the pause-and-plan response, which couldn’t look more different from the fight-or-flight response.

14. Your instincts are pushing you toward a potentially bad decision. What’s needed, therefore, is protection of yourself by yourself. This is what self-control is all about. The most helpful response will be to slow you down, not speed you up (as a fight-or-flight response does). And this is precisely what the pause-and-plan response does. The perception of an internal conflict triggers changes in the brain and body that help you slow down and control your impulses.

15. The single best physiological measurement of the pause-and-plan response is something called heart rate variability—a measurement most people have never heard of, but one that provides an amazing window into the body’s state of stress or calm.

16. Heart rate variability is such a good index of willpower that you can use it to predict who will resist temptation, and who will give in.

17. Studies also show that people with higher heart rate variability are better at ignoring distractions, delaying gratification, and dealing with stressful situations.

18. You won’t find many quick fixes in this book, but there is one way to immediately boost willpower: Slow your breathing down to four to six breaths per minute. That’s ten to fifteen seconds per breath—slower than you normally breathe, but not difficult with a little bit of practice and patience. Slowing the breath down activates the prefrontal cortex and increases heart rate variability, which helps shift the brain and body from a state of stress to self-control mode. A few minutes of this technique will make you feel calm, in control, and capable of handling cravings or challenges.

19. Heart rate variability steadily increases as your breathing rate drops below twelve per minute.

20. One study found that a daily twenty-minute practice of slowed breathing increased heart rate variability and reduced cravings and depression among adults recovering from substance abuse and post-traumatic stress disorder.

21. Exercise turns out to be the closest thing to a wonder drug that self-control scientists have discovered. For starters, the willpower benefits of exercise are immediate. Fifteen minutes on a treadmill reduces cravings, as seen when researchers try to tempt dieters with chocolate and smokers with cigarettes. The long-term effects of exercise are even more impressive. It not only relieves ordinary, everyday stress, but it’s as powerful an antidepressant as Prozac. Working out also enhances the biology of self-control by increasing baseline heart rate variability and training the brain.

22. If you are surviving on less than six hours of sleep a night, there’s a good chance you don’t even remember what it’s like to have your full willpower. Being mildly but chronically sleep deprived makes you more susceptible to stress, cravings, and temptation. It also makes it more difficult to control your emotions, focus your attention, or find the energy to tackle the big “I will” power challenges.

23. The good news is, all of this is reversible. When the sleep-deprived catch a better night’s sleep, their brain scans no longer show signs of prefrontal cortex impairment. In fact, they look just like the brains of the well-rested.

24. In one study, five minutes of breath-focus meditation a day helped recovering addicts fall asleep. This added one hour a night to their quality sleep time, which in turn significantly reduced the risk of drug use relapse. So for better willpower, go to sleep already.

25. This may seem to work in the short term, but in the long term, nothing drains willpower faster than stress. The biology of stress and the biology of self-control are simply incompatible. Both the fight-or-flight and pause-and-plan responses are about energy management, but they redirect your energy and attention in very different ways. The fight-or-flight response floods the body with energy to act instinctively, and steals it from the areas of the brain needed for wise decision making.

26. Welcome to one of the most robust, if troubling, findings from the science of self-control: People who use their willpower seem to run out of it. Smokers who go without a cigarette for twenty-four hours are more likely to binge on ice cream. Drinkers who resist their favorite cocktail become physically weaker on a test of endurance. Perhaps most disturbingly, people who are on a diet are more likely to cheat on their spouse. It’s as if there’s only so much willpower to go around. Once exhausted, you are left defenseless against temptation—or at least disadvantaged.

27. Researchers have found that self-control is highest in the morning and steadily deteriorates over the course of the day. By the time you get to the stuff that really matters to you, like going to the gym after work, tackling the big project, keeping your cool when your kids turn the couch into a finger paint masterpiece, or staying away from the emergency pack of cigarettes stashed in your drawer, you may find yourself out of willpower.

28. The more a person’s blood sugar dropped after a self-control task, the worse his performance on the next task. It appeared as if self-control was draining the body of energy, and this energy loss was weakening self-control.

29. Low blood sugar levels turn out to predict a wide range of willpower failures, from giving up on a difficult test to lashing out at others when you’re angry. Gailliot, now a professor at Zirve University in Turkey, has found that people with low blood sugar are also more likely to rely on stereotypes and less likely to donate money to charity or help a stranger. It is as if running low on energy biases us to be the worst versions of ourselves. In contrast, giving participants a sugar boost turns them back into the best versions of themselves: more persistent and less impulsive; more thoughtful and less selfish.

30. Other studies have found that committing to any small, consistent act of self-control—improving your posture, squeezing a handgrip every day to exhaustion, cutting back on sweets, and keeping track of your spending—can increase overall willpower.

31. The widely observed scientific finding that self-control is limited may reflect people’s beliefs about willpower, not their true physical and mental limits.

32. When your willpower is running low, find renewed strength by tapping into your want power. For your biggest willpower challenge, consider the following motivations: 

  1. How will you benefit from succeeding at this challenge? What is the payoff for you personally? Greater health, happiness, freedom, financial security, or success? 
  2. Who else will benefit if you succeed at this challenge? Surely there are others who depend on you and are affected by your choices. How does your behavior influence your family, friends, coworkers, employees or employer, and community? How would your success help them? 
  3. Imagine that this challenge will get easier for you over time if you are willing to do what is difficult now. Can you imagine what your life will be like, and how you will feel about yourself, as you make progress on this challenge? Is some discomfort now worth it if you know it is only a temporary part of your progress?

33. Ayelet Fishbach, professor at the University of Chicago Graduate School of Business, and Ravi Dhar, professor at the Yale School of Management, have shown that making progress on a goal motivates people to engage in goal-sabotaging behavior.

34. The problem with progress is how it makes us feel—and even then, it’s only a problem if we listen to the feeling instead of sticking to our goals. Progress can be motivating, and even inspire future self-control, but only if you view your actions as evidence that you are committed to your goal. In other words, you need to look at what you have done and conclude that you must really care about your goal, so much so that you want to do even more to reach it. This perspective is easy to adopt; it’s just not our usual mindset. More typically, we look for the reason to stop.

35. How do you focus on commitment instead of progress? A study by researchers at Hong Kong University of Science and the University of Chicago provides one strategy. When they asked students to remember a time they turned down a temptation, moral licensing ensued, and 70 percent took the next opportunity to indulge. But when they also asked the participants to remember why they had resisted, the licensing effect disappeared—69 percent resisted temptation.

36. We wrongly but persistently expect to make different decisions tomorrow than we do today. I’ll smoke this one cigarette, but starting tomorrow, I’m done. I’ll skip the gym today, but I’m sure I’ll go tomorrow. I’ll splurge on holiday gifts, but then no more shopping for at least three months.

37. Behavioral economist Howard Rachlin proposes an interesting trick for overcoming the problem of always starting a change tomorrow. When you want to change a behavior, aim to reduce the variability in your behavior, not the behavior itself. He has shown that smokers asked to try to smoke the same number of cigarettes every day gradually decrease their overall smoking—even when they are explicitly told not to try to smoke less.

38. How does the reward system compel us to act? When the brain recognizes an opportunity for reward, it releases a neurotransmitter called dopamine. Dopamine tells the rest of the brain what to pay attention to and what to get our greedy little hands on. A dopamine rush doesn’t create happiness itself —the feeling is more like arousal. We feel alert, awake, and captivated.

39. When dopamine is released by one promise of reward, it also makes you more susceptible to any other kind of temptation. For example, erotic images make men more likely to take financial risks, and fantasizing about winning the lottery leads people to overeat—two ways daydreaming about unattainable rewards can get you into trouble. High levels of dopamine amplify the lure of immediate gratification, while making you less concerned about long-term consequences.

40. The reward system of the brain also responds to novelty and variety. Your dopamine neurons eventually become less responsive to familiar rewards, even ones you really enjoy, whether it’s a daily mocha latte or the same old lunch special. It’s not a coincidence that places like Starbucks and Jack in the Box are constantly introducing new variations of the standard fare, and clothing retailers roll out new color choices for their wardrobe basics. Regular cup of joe?

41. Businesses also use smells to manufacture desire where none existed. An appetizing odor is one of the fastest ways to trigger the promise of reward, and as soon as the scented molecules land on your olfactory receptors, the brain will begin searching for the source.

42. The promise of reward has even been used to help people overcome addiction. One of the most effective intervention strategies in alcohol and drug recovery is something called the fish bowl. Patients who pass their drug tests win the opportunity to draw a slip of paper out of a bowl. About half of these slips have a prize listed on them, ranging in value from $1 to $20. Only one slip has a big prize, worth $100. Half of the slips have no prize value at all—instead, they say, “Keep up the good work.” This means that when you reach your hand into the fish bowl, the odds are you’re going to end up with a prize worth $1 or a few kind words. This shouldn’t be motivating—but it is. In one study, 83 percent of patients who had access to fish bowl rewards stayed in treatment for the whole twelve weeks, compared with only 20 percent of patients receiving standard treatment without the promise of reward. Eighty percent of the fish bowl patients passed all their drug tests, compared with only 40 percent of the standard treatment group. When the intervention was over, the fish bowl group was also far less likely to relapse than patients who received standard treatment—even without the continued promise of reward.

43. We humans find it nearly impossible to distinguish the promise of reward from whatever pleasure or payoff we are seeking.

44. When you’re feeling down, what do you do to feel better? If you’re like most people, you turn to the promise of reward. According to the American Psychological Association (APA), the most commonly used strategies for dealing with stress are those that activate the brain’s reward system: eating, drinking, shopping, watching television, surfing the Web, and playing video games. And why not? Dopamine promises us that we’re going to feel good. It’s only natural that we turn to the biggest dopamine releasers when we want to feel better. Call it the promise of relief.

45. The brain, it turns out, is especially susceptible to temptation when we’re feeling bad. Scientists have come up with clever ways to stress out their laboratory subjects, and the results are always the same.

46. When smokers imagine a trip to the dentist, they experience off-the-chart cravings for a cigarette. When binge-eaters are told they will have to give a speech in public, they crave high-fat, sugary foods. Stressing out lab rats with unpredictable electric shocks (to the body, not the brain’s reward center!) will make them run for sugar, alcohol, heroin, or whatever reward researchers have made available in their cage. Outside the laboratory, real-world stress increases the risk of relapse among smokers, recovering alcoholics, drug addicts, and dieters.

47. Neuroscientists have shown that stress—including negative emotions like anger, sadness, self-doubt, and anxiety—shifts the brain into a reward-seeking state. You end up craving whatever substance or activity your brain associates with the promise of reward, and you become convinced that the “reward” is the only way to feel better. For example, when a cocaine addict remembers a fight with a family member or being criticized at work, his brain’s reward system becomes activated, and he experiences intense cravings for cocaine.

48. While many of the most popular stress-relief strategies fail to make us feel better, some strategies really work. According to the American Psychological Association, the most effective stress-relief strategies are exercising or playing sports, praying or attending a religious service, reading, listening to music, spending time with friends or family, getting a massage, going outside for a walk, meditating or doing yoga, and spending time with a creative hobby. (The least effective strategies are gambling, shopping, smoking, drinking, eating, playing video games, surfing the Internet, and watching TV or movies for more than two hours.) 

49. The main difference between the strategies that work and the strategies that don’t? Rather than releasing dopamine and relying on the promise of reward, the real stress relievers boost moodenhancing brain chemicals like serotonin and GABA, as well as the feel-good hormone oxytocin. They also help shut down the brain’s stress response, reduce stress hormones in the body, and induce the healing relaxation response. Because they aren’t exciting like the dopamine releasers, we tend to underestimate how good they will make us feel. And so we forget about these strategies not because they don’t work, but because when we’re stressed, our brains persistently mis-predict what will make us happy. This means that we’ll often talk ourselves out of doing the very thing that will actually make us feel better.

50. It doesn’t take planes flying into buildings to press our inner panic buttons. In fact, it doesn’t even take real deaths to set us spending—television dramas and movies can have the same effect. In one study, watching a death scene in the 1979 tearjerker film The Champ made people willing to pay three times as much for something they didn’t need (and would later regret). Importantly, the participants in this study were oblivious to the fact that watching the film had influenced what they were willing to pay.

51. Not surprisingly, people who drank too much the previous night felt worse in the morning— headaches, nausea, fatigue. But their misery wasn’t limited to hangovers. Many also felt guilty and ashamed. That’s where things get disturbing. The worse a person felt about how much they drank the night before, the more they drank that night and the next. The guilt was driving them back to the bottle. 

52. Welcome to one of the biggest threats to willpower worldwide: the “what-the-hell effect.” First coined by dieting researchers Janet Polivy and C. Peter Herman, the what-the-hell effect describes a cycle of indulgence, regret, and greater indulgence.

53. Any setback can create the same downward spiral. In one not-so-nice study, Polivy and Herman rigged a scale to make dieters think they had gained five pounds. The dieters felt depressed, guilty, and disappointed with themselves—but instead of resolving to lose the weight, they promptly turned to food to fix those feelings.

54. And yet getting rid of guilt kept the women from overindulging in the taste test. We may think that guilt motivates us to correct our mistakes, but it’s just one more way that feeling bad leads to giving in.

55. If you think that the key to greater willpower is being harder on yourself, you are not alone. But you are wrong. Study after study shows that self-criticism is consistently associated with less motivation and worse self-control. It is also one of the single biggest predictors of depression, which drains both “I will” power and “I want” power. In contrast, self-compassion—being supportive and kind to yourself, especially in the face of stress and failure—is associated with more motivation and better self-control.

56. Whether we look to economics, psychology, or neuroscience for an explanation, many of our problems with temptation and procrastination come back to one uniquely human problem: how we think about the future.

57. One reason we’re so susceptible to immediate gratification is that our brain’s reward system did not evolve to respond to future rewards. Food was the reward system’s original target, which is why humans are still exceptionally responsive to the smell or sight of anything yummy. When dopamine was first perfecting its effects in the human brain, a reward that was far off—whether by sixty miles or sixty days—was irrelevant to daily survival.

58. To delay gratification, the prefrontal cortex has to cool off the promise of reward. It’s not an impossible feat—after all, that’s what the prefrontal cortex is there for. But it has to fight a feeling that’s been known to make rats run across electrified grids and men blow their life savings on a slot machine. In other words, it’s not easy.

59. To really overwhelm our prefrontal cortex, the reward must be available now, and—for maximum effect—you need to see it. As soon as there is any distance between you and the temptation, the power of balance shifts back to the brain’s system of self-control.

60. Anything you can do to create that distance will make it easier to say no. For example, one study found that just putting a candy jar inside a desk drawer instead of on top of the desk reduced office workers’ candy consumption by one third. It isn’t any more difficult to open a drawer than to reach across a desk, but putting the candy away reduced the constant stimulation of desire. When you know your own triggers, putting them out of sight can keep them from tempting your mind.

61. Ten minutes might not seem like much time to wait for something you want, but neuroscientists have discovered that it makes a big difference in how the brain processes a reward. When immediate gratification comes with a mandatory ten-minute delay, the brain treats it like a future reward. The promise-of-reward system is less activated, taking away the powerful biological impulse to choose immediate gratification.

62. To find out, he created a measure of “future-self continuity”—the degree to which you see your future self as essentially the same person as your current self. Not everyone views the future self as a total stranger; some of us feel quite close and connected to our future selves.

63. His most recent work shows that people with low future-self continuity behave less ethically in business role-play scenarios.

64. It is as if feeling disconnected from our future selves gives us permission to ignore the consequences of our actions. In contrast, feeling connected to our future selves protects us from our worst impulses.

65.You can help yourself make wiser choices by sending yourself to the future (DeLorean not required 27 ). Below are three ideas for making the future feel real, and for getting to know your future self. Pick one that appeals to you and try it out this week. 

  1. Create a Future Memory. Neuroscientists at the University Medical Center HamburgEppendorf in Germany have shown that imagining the future helps people delay gratification. 
  2. Send a Message to Your Future Self. 
  3. Imagine Your Future Self. Studies show that imagining your future self can increase your present self ’s willpower. One experiment asked couch potatoes to imagine either a hoped-for future self who exercised regularly and enjoyed excellent health and energy, or a feared future self who was inactive and suffering the health consequences. Both visualizations got them off the couch, and they were exercising more frequently two months later than a control group that did not imagine a future self.

66. Willpower failures may be contagious, but you can also catch self-control.

67. When Christakis and Fowler looked at participants’ weight over time, they saw what looked like a real epidemic. Obesity was infectious, spreading within families and from friend to friend. When a friend became obese, a person’s own future risk of becoming obese increased by 171 percent. A woman whose sister became obese had a 67 percent increased risk, and a man whose brother became obese had a 45 percent increased risk.

68. As unsettling as it may be, the implication is clear: Both bad habits and positive change can spread from person to person like germs, and nobody is completely immune.

69. What does all this mean for your self-control? The good news is, goal contagion is limited to goals you already, at some level, share. You can’t catch a brand-new goal from a brief exposure the way you can catch a flu virus. A nonsmoker is not going to catch a nicotine craving when a friend pulls out a cigarette. But another person’s behavior can activate a goal in your mind that was not currently in charge of your choices. As we’ve seen, a willpower challenge always involves a conflict between two competing goals.

70. When we observe evidence of other people ignoring rules and following their impulses, we are more likely to give in to any of our own impulses. This means that anytime we see someone behaving badly, our own self-control deteriorates (bad news for fans of reality television, where the three rules of high ratings are: Drink too much, pick a fight, and sleep with someone else’s boyfriend). Hearing about someone cheating on their taxes might make you feel freer to cheat on your diet.

71. We may be willing to give up our vices and cultivate new virtues if we believe that it will more firmly secure us a spot in our most cherished tribe.

72. The best predictor of whether a student cheats is whether he believes other students cheat, not the severity of penalties or whether he thinks he will be caught. When students believe that their classmates cheat, a relatively honest class can become a class full of students who text their friends for answers during an exam (yes, I have caught a student trying this).

73. Look for a new “tribe” you could join. It could be a support group, a class, a local club, an online community, or even subscribing to a magazine that supports your goals. Surrounding yourself with people who share your commitment to your goals will make it feel like the norm.

74. People who imagine how proud they will feel when they accomplish a goal—from quitting smoking to donating blood—are more likely to follow through and succeed. Anticipated disapproval works too: People are more likely to use condoms when they imagine feeling ashamed if others knew that they had unprotected sex.

75. Even when shame is anticipatory, it may fail us when we need it most. When health-conscious individuals are asked to imagine a chocolate cake in front of them, and then imagine the shame they would feel if they ate it, they are less likely to (hypothetically) eat it. However, when researchers actually placed a large piece of chocolate cake from the Cheesecake Factory on the table, complete with a bottle of water, fork, and napkin, shame had the opposite effect. Only 10 percent resisted the temptation. Anticipatory shame might be able to keep you from walking into the Cheesecake Factory, but when the temptation is in front of you, it has no power over the promise of reward. Once your dopamine neurons are firing, feeling bad intensifies your desire and makes you more likely to give in.

76. Pride, on the other hand, pulls through even in the face of temptation. Forty percent of participants who imagined how proud they’d be for resisting the Cheesecake Factory cake didn’t take a single bite. One reason pride helped is that it took people’s minds off the cake. In contrast, shame paradoxically triggered anticipatory pleasure, and the participants reported more temptation-related thoughts like “It smells so good,” and “It will taste great.” Another reason boils down to biology: Laboratory studies reveal that guilt decreases heart rate variability, our physiological reserve of willpower. Pride, on the other hand, sustains and even increases this reserve.
