By changing what your brain predicts, you can change the reality your brain creates for you and the limits it sets for you.<\/p>\n\n\n\n<p>Read below for a brief overview of <em>The Expectation Effect<\/em>.<\/p>\n\n\n\n<!--more-->\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-expectation-effect-by-david-robson\"><strong><em>The Expectation Effect<\/em> by David Robson<\/strong><\/h2>\n\n\n\n<p>We\u2019re shaped by what we believe about ourselves and the world around us. Our brains, bodies, and environments conspire to create what researchers call expectation effects, so that <strong>what we expect to be or do becomes our reality<\/strong>. This is a basic consequence of the brain\u2019s use of predictions: It constructs our reality using not only the information we perceive with our senses but also our experiences and the expectations we learn by observing the world around us.&nbsp;<\/p>\n\n\n\n<p>David Robson&#8217;s <a href=\"https:\/\/us.macmillan.com\/books\/9781250827630\/theexpectationeffect\" target=\"_blank\" rel=\"noreferrer noopener\"><em>The Expectation Effect<\/em><\/a> argues that if you let them, expectation effects can harm your physical and mental well-being. For example, if you expect to age poorly, you might experience more illnesses as you get older. However, expectation effects can also be positive. By learning how this process works in the brain, you can use expectation effects to improve your response to stress, your attitudes toward food, your ability to <a href=\"https:\/\/www.shortform.com\/blog\/how-to-push-yourself\/\">push yourself<\/a> in exercise, and even your health as you age.&nbsp;<\/p>\n\n\n\n<p>Robson is a science writer and the author of <a href=\"https:\/\/www.amazon.com\/Intelligence-Trap-Smart-People-Mistakes\/dp\/0393651428\" target=\"_blank\" rel=\"noreferrer noopener\"><em>The Intelligence Trap<\/em><\/a> (2019). He explains that after his encounter with depression, he became interested in the brain\u2019s ability to influence our well-being, which led to 2022\u2019s <em>The Expectation Effect<\/em>.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What Are Expectation Effects?<\/strong><\/h3>\n\n\n\n<p>An expectation effect occurs when <strong>your beliefs exert an influence over your well-being<\/strong>, as when you take a pill for a headache and feel better not because of what\u2019s in the pill but because you expect the pill to cure your headache. According to Robson, your body, brain, and the culture you live in create these effects, which are powerful and pervasive. In this section of the guide, we\u2019ll explore how the brain\u2019s perception process creates expectation effects and how what we believe becomes our reality.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>How Does Your Brain Construct Your Reality?<\/strong><\/h4>\n\n\n\n<p>To understand how expectation effects work, it helps to know that <strong>your brain doesn\u2019t just perceive reality\u2014it actively constructs it<\/strong>. Robson explains that as you <a href=\"https:\/\/www.shortform.com\/blog\/perception-of-the-world\/\">perceive the world<\/a> around you, your brain draws on information relayed by your senses as well as information inferred from your past experiences. In the process, your brain generates predictions about the <a href=\"https:\/\/www.shortform.com\/blog\/sensory-information-processing\/\">sensory information<\/a> it receives, like when you see a fly and your brain predicts its path so that you can swat it away from your face. The brain constructs a representation of what it thinks is happening and what it predicts will happen, and you perceive this representation as reality.<\/p>\n\n\n\n<p>The brain relies heavily on these predictions. The visual cortex, the <a href=\"https:\/\/www.shortform.com\/blog\/what-are-the-regions-of-the-brain\/\">region of the brain<\/a> that processes information received from the eyes, has extensive connections to other brain regions that make predictions\u2014which illustrates how<strong> the brain is wired to rely on prior knowledge<\/strong>. Robson notes that it makes evolutionary sense for the brain to depend on predictions: Using predictions to inform perception reduces the amount of sensory information it has to process and enables it to focus on surprising sensory details, like the snake that you might just step on if your brain doesn\u2019t alert you to get out of the way.&nbsp;<\/p>\n\n\n\n<p>Robson points out that although the brain is good at making predictions, it can <strong>sometimes get tripped up<\/strong>. Your feelings and expectations can bias your brain\u2019s predictions, like when you\u2019re <a href=\"https:\/\/www.shortform.com\/blog\/how-to-stop-feeling-nervous\/\">feeling nervous<\/a> and your expectations about the situation make you think someone looks angry when they aren\u2019t. Though perception feels objective, it\u2019s not. As we\u2019ll see in the next section, your body sometimes acts on your brain\u2019s mistaken predictions, creating expectation effects. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>How Do Your Beliefs Become Your Reality?&nbsp;<\/strong><\/h4>\n\n\n\n<p>Expectation effects come into play because when it comes to predictions about our own bodies and minds, <strong>our expectations exert such a strong influence that the brain makes them true<\/strong>. Robson explains that this often happens because the brain produces physiological changes throughout the body, like when you take an herbal remedy that might not reduce your aches and pains on its own, but works because your brain signals your body to reduce inflammation when you take it.<\/p>\n\n\n\n<p>Our memories and beliefs aren\u2019t the only sources of predictions that become reality. Robson notes that sometimes, our <strong>expectations come from the culture around us<\/strong>, for example, when we absorb the message that growing older means getting slower or weaker. If we believe this message strongly enough, the brain makes it our reality as we age.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>What About Positive Thinking or the Law of Attraction?&nbsp;&nbsp;<\/strong><\/h4>\n\n\n\n<p>Robson emphasizes that expectation effects are <strong>not the same thing as positive thinking or the <a href=\"https:\/\/www.shortform.com\/blog\/manifesting-money-the-secret\/\">law of attraction<\/a><\/strong>, which he characterizes as \u201cpseudoscience.\u201d <a href=\"https:\/\/www.shortform.com\/blog\/the-law-of-attraction-explained\/\">The law of attraction<\/a> is the principle that <a href=\"https:\/\/www.shortform.com\/blog\/how-to-have-a-positive-mindset\/\">positive thoughts<\/a> can attract the things you want. By contrast, expectation effects work via psychological and physiological mechanisms set in motion by the specific expectations we have about our bodies or minds.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How to Handle Expectation Effects That Influence Your Physical Well-Being<\/strong><\/h3>\n\n\n\n<p>Now that we understand how physiological and psychological expectation effects work, we\u2019ll look at specific expectation effects that you might recognize from your own life. For each, we\u2019ll also explore how you can either prevent it from happening or put it to use to improve your physical or mental health. First, we\u2019ll explore expectation effects that affect your physical health. Though we\u2019re separating expectation effects that influence our physical well-being from those that influence our psychological well-being, Robson emphasizes that an expectation effect that influences your body can (and will) influence your mind, and vice versa. That\u2019s one reason why expectation effects are so powerful.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Placebo Effect<\/strong><\/h4>\n\n\n\n<p>Perhaps the most well-known expectation effect is <a href=\"https:\/\/www.shortform.com\/blog\/placebo-effect-psychology\/\">the placebo effect<\/a>. A placebo is a treatment that doesn\u2019t exert a direct chemical effect on the body but can have an <strong>indirect effect because of our expectations<\/strong>. Robson explains that when we think a placebo treatment will work, these expectations can create the same biological effects we\u2019d experience with the actual treatment. This works even when we know that we\u2019re taking a placebo because our subconscious expectations still tell the brain that it should start the biological processes that promote healing.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Nocebo Effect<\/strong><\/h4>\n\n\n\n<p>The brain\u2019s predictive processing also produces an expectation effect that is in many ways the reverse of the placebo effect: the <a href=\"https:\/\/www.shortform.com\/blog\/what-is-the-nocebo-effect\/\">nocebo effect<\/a>. This effect occurs when <strong>we expect to experience a symptom or illness and then develop it<\/strong>. According to Robson, this isn\u2019t a result of hypochondria and it\u2019s not all \u201cin your head\u201d: An expectation of getting sick signals the brain to enact the same physiological changes brought on by a real pathogen. Scientists have even observed extreme cases where the nocebo effect increases our risk of death.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Psychogenic Illness<\/strong><\/h4>\n\n\n\n<p>Nocebo responses can be contagious, and people can transmit expectations of illness via social contagion. Robson reports that occasionally, this manifests as an outbreak of a psychogenic illness, a mass illness with a psychological origin. <strong>Psychogenic illnesses result when expectations about a disease spread<\/strong>. It starts with one person, who experiences symptoms and talks about them. Then it spreads, affecting people who weren\u2019t exposed to the actual or assumed environmental origin, like when Tourette-like tics <a href=\"https:\/\/www.health.harvard.edu\/blog\/tics-and-tiktok-can-social-media-trigger-illness-202201182670\" target=\"_blank\" rel=\"noreferrer noopener\">spread across TikTok<\/a>.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Physical Limits in Sports and Exercise<\/strong><\/h4>\n\n\n\n<p>Another place that expectation effects manifest is in your body\u2019s regulation of what you can do in a workout or practice session. In fact, Robson reports that <strong>your limits in sports or exercise might be more psychological than physical<\/strong>. Your brain predicts how much effort you can expend and at what intensity and limits your performance accordingly. It makes sense for the brain to tend toward conservative estimates of our physical capabilities, which can help us to conserve energy and control the risk for injury.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Responses to Food<\/strong><\/h4>\n\n\n\n<p>Expectation effects also play a role in how your body responds to food. Robson explains that your feelings about food determine whether you enjoy your meals, feel full after eating, and maintain a healthy weight over time. That\u2019s because <strong>your mindset about food influences your physiological response<\/strong>. A feeling of enjoying your food rather than depriving yourself for the sake of health makes a difference. If you eat a healthy meal and expect that it won\u2019t fill or nourish you, that prediction comes true: Your body may not absorb the nutrients, and you may feel hungry again soon after eating.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Aging<\/strong><\/h4>\n\n\n\n<p>Expectation effects can even influence how you age and how long you live\u2014that\u2019s how powerful your beliefs about aging are. Robson reports that <strong>your expectations about aging might be just as important as your actual age in determining your well-being<\/strong>. People with negative attitudes toward aging\u2014like expecting to experience illness and frailty with age\u2014are more likely to develop heart problems and stroke. Conversely, people with positive attitudes about aging\u2014like higher expectations for the energy level and usefulness they\u2019ll feel as they age\u2014seem to have a lower risk for some types of dementia.&nbsp;<\/p>\n\n\n\n<p>To age better and live longer, Robson recommends adopting a few strategies:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How to Handle Expectation Effects That Influence Your Mental Well-Being<\/strong><\/h3>\n\n\n\n<p>Next, we\u2019ll look at expectation effects that influence your mental and <a href=\"https:\/\/www.shortform.com\/blog\/emotional-health-and-well-being\/\">emotional health<\/a>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Stress Response<\/strong><\/h4>\n\n\n\n<p>Expectation effects play a role in our response to many feelings, including stress. Robson thinks stress may hurt us not because it\u2019s inherently harmful but because we believe it\u2019s bad for us. This means that <strong>we experience negative physiological effects from stress when we encounter it because we <em>expect<\/em> them<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Insomnia<\/strong><\/h4>\n\n\n\n<p>Just as an expectation effect worsens our experience with stress via a negative psychological response, a similarly negative response makes insomnia worse than it needs to be, according to Robson. When we lie awake at night, wishing we were asleep, <strong>we fall into ruminative patterns of thought that keep us awake longer<\/strong>. Worrying about sleep causes more sleep loss, and experts think that worrying about not getting enough sleep is worse for your health than actually getting inadequate sleep.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Limits of Self-Control and Mental Focus<\/strong><\/h4>\n\n\n\n<p>Expectation effects also curtail your mental ability. Robson explains that we tend to assume that we have a limited amount of self-control and mental focus, but research shows that <strong>we place these limitations on ourselves<\/strong>. Whether you believe that your mental resources are limited or unlimited matters: The power of this belief means that expecting mental effort to feel energizing or anticipating that you can improve your concentration with effort can make these things true.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Intelligence and Creativity<\/strong><\/h4>\n\n\n\n<p>Finally, expectation effects also influence the quality of the intelligence or creativity you can bring to a specific task. Robson points out that your expectations about your abilities often come from people around you. <strong>When you face a challenging task and think you are (or aren\u2019t) up to the task, your expectations will likely come true<\/strong>. Memory, problem-solving, intellectual stamina, and resilience are influenced by what we believe about ourselves. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is David Robson&#8217;s The Expectation Effect about?
