Decision Fatigue is a psychological phenomenon characterized by diminished willpower and impulsive decision-making after facing multiple choices, often due to cognitive overload. It can lead to procrastination and impulse purchases. Mitigation involves prioritizing decisions and taking breaks. Understanding it is crucial in marketing and time management.
Reduced Willpower: Decision fatigue often results in diminished self-control and willpower. As individuals make choices, especially those requiring discipline or restraint, they may find it increasingly challenging to resist temptations or make decisions that align with their long-term goals. For example, after a taxing day at work, someone may be more likely to indulge in unhealthy snacks or skip their evening workout.
Impaired Judgment: Those experiencing decision fatigue may struggle to evaluate options objectively. The mental exhaustion stemming from continuous decision-making can lead to suboptimal decision quality. Whether it’s choosing between job candidates, evaluating investment opportunities, or even deciding on dinner options, individuals may find themselves making less-than-ideal choices when decision fatigue sets in.
Causes of Decision Fatigue
Cognitive Overload: The continuous process of making numerous decisions, especially within a short timeframe, can overwhelm an individual’s cognitive capacity. Every decision, no matter how trivial, demands mental resources, and these resources are finite. As the day progresses and choices accumulate, cognitive resources become depleted, leading to decision fatigue. A study conducted by researchers Sheena Iyengar and Mark Lepper, known as the “Jam Experiment,” illustrated this phenomenon. Shoppers were presented with either a limited or an extensive selection of jams to taste and choose from. While the larger assortment attracted more attention, the shoppers presented with fewer choices were more likely to make a purchase. This suggests that the mental effort of evaluating numerous options can lead to decision fatigue and reduced decision quality.
Extensive Choices: An abundance of options or choices in various aspects of life can increase the likelihood of decision fatigue. When confronted with too many alternatives, individuals may become mentally fatigued faster. For example, in the realm of technology, consumers often face a multitude of options when purchasing smartphones, laptops, or other electronic devices. The process of comparing specifications, features, and prices can be mentally taxing and lead to decision fatigue, possibly resulting in less satisfying choices.
Effects of Decision Fatigue
Impulse Purchases: One common manifestation of decision fatigue occurs during shopping, especially in large retail environments. Shoppers may start with a well-thought-out shopping list but gradually succumb to decision fatigue as they traverse the aisles. Towards the end of their shopping trips, they may abandon their initial plans and engage in impulse purchases, buying items they hadn’t originally intended to purchase. Decision fatigue weakens their resolve, making them more susceptible to marketing tactics and impulsive choices.
Procrastination: Decision fatigue can also result in procrastination and delays in tackling important decisions or tasks. As individuals’ mental energy wanes, they may opt to postpone making choices they deem mentally taxing. For instance, someone might delay making a career-changing decision, such as accepting a new job offer, because they lack the mental energy to thoroughly evaluate the potential consequences and benefits. Similarly, students might procrastinate when faced with a complex assignment, choosing to put it off until they feel more mentally prepared to make decisions about research, structure, and content.
Mitigation Strategies for Decision Fatigue
Recognizing the impact of decision fatigue is the first step towards managing it effectively. Fortunately, there are several strategies that individuals can employ to mitigate the negative effects of decision fatigue:
Prioritization: Focusing on critical decisions and delegating or simplifying less important ones can help conserve cognitive resources. By channeling mental energy where it matters most, individuals can reduce the likelihood of experiencing decision fatigue. For example, a business executive might prioritize key strategic decisions while delegating routine operational choices to subordinates.
Scheduled Breaks: Taking regular breaks during decision-intensive activities allows individuals to recharge their mental faculties. Brief respites can help reduce the cumulative effect of decision fatigue over time. During these breaks, engaging in relaxing activities, practicing mindfulness, or simply taking a walk can be effective ways to refresh cognitive resources. In workplaces that value productivity, incorporating short breaks into the daily routine can be an effective strategy for maintaining cognitive clarity and decision-making efficacy.
Routine and Habit: Creating routines and habits for certain aspects of life can alleviate decision fatigue. For example, adopting a consistent morning routine for tasks like dressing, breakfast, and exercise can reduce the number of choices individuals need to make early in the day. By automating these decisions, individuals can conserve mental energy for more important matters.
Simplify Choices: Simplifying choices can be a powerful strategy for managing decision fatigue. In some cases, individuals can limit the number of options available to them. For instance, creating a capsule wardrobe with a limited selection of clothing items that mix and match well can reduce the daily decision-making burden of selecting outfits. Similarly, adopting a minimalist approach to home decor can minimize the choices individuals need to make when arranging their living spaces.
Real-World Examples of Decision Fatigue
Supermarket Shopping: A classic example of decision fatigue occurs during supermarket shopping. As shoppers navigate aisles filled with a multitude of products, they are continuously faced with choices. From selecting the type of bread to choosing between various brands of toothpaste, the decisions add up. Towards the end of their shopping trips, shoppers may experience decision fatigue, leading them to make impulsive choices. They may succumb to marketing tactics, opt for items on display, or choose less healthy food options. This phenomenon is not only observable but also well-documented, making it a prominent real-world example of decision fatigue.
Parole Board Decisions: The impact of decision fatigue on significant judgments is exemplified by studies involving parole board decisions. Researchers have found that the timing of parole hearings can influence the outcomes. Parole boards are more likely to grant parole in the morning when they are less fatigued compared to the afternoon. As the day progresses and board members make a series of decisions, their cognitive resources become depleted, potentially leading to more conservative and risk-averse judgments. This example underscores how decision fatigue can even affect critical and life-altering choices.
Applications of Understanding Decision Fatigue
Understanding the concept of decision fatigue has several practical applications across various domains:
Marketing Strategies: Businesses can designmarketing campaigns that take into account consumer decision fatigue. Presenting choices in a simplified, manageable way can reduce cognitive load and increase the likelihood of favorable consumer decisions. For instance, offering curated selections or bundles of products can make it easier for customers to make purchasing decisions, potentially leading to higher sales.
Time Management: Individuals can optimize their daily routines to minimize decision fatigue. Strategies such as meal planning, setting priorities, and automating repetitive choices can help conserve mental energy. By reducing the mental effort required for routine decisions, individuals can allocate their cognitive resources more effectively to important tasks and challenges.
Health and Well-being: Awareness of decision fatigue can also be beneficial in personal health and well-being. For example, individuals seeking to maintain a balanced diet may experience decision fatigue when faced with numerous food choices. By planning meals in advance or adhering to a specific dietary regimen, they can simplify food-related decisions and make healthier choices more consistently.
Education and Learning: In educational settings, instructors and learners can recognize the potential effects of decision fatigue on learning outcomes. Prolonged and intensive decision-making tasks can lead to mental exhaustion, reducing learners’ ability to engage effectively with educational content. Educators can design learning experiences that incorporate breaks and limit the number of decisions learners need to make in a single session.
Product Design: Understanding decision fatigue is essential for user experience (UX) designers and product developers. Simplifying user interfaces, reducing the number of options presented simultaneously, and providing clear guidance can enhance the user experience and prevent choice overload, a phenomenon closely related to decision fatigue. By optimizing productdesign, developers can ensure that users can make informed decisions without becoming overwhelmed.
Public Policy: Policymakers can consider decision fatigue when designing public policies and services. For instance, simplifying forms, streamlining procedures, and providing clear, concise information can reduce the cognitive load on citizens interacting with government agencies. This approach promotes accessibility and ensures that individuals can make informed decisions without unnecessary mental fatigue.
Case Studies
Meal Planning: When trying to decide what to cook for dinner every night, individuals may experience decision fatigue, leading to repeated meal choices or opting for takeout.
Wardrobe Selection: Fashion designers like Steve Jobs and Mark Zuckerberg famously adopted a minimalist wardrobe to reduce decision fatigue related to clothing choices.
Health and Fitness: Maintaining a healthy lifestyle can be challenging when individuals face numerous dietary and exercise decisions daily, potentially leading to poor health choices.
Educational Planning: Students deciding on courses, majors, or extracurricular activities can experience decision fatigue, affecting their academic journey.
Investment Decisions: Investors who constantly monitor and make frequent changes to their portfolios may experience decision fatigue, potentially leading to impulsive trading decisions.
Parenting: Parents, particularly new parents, often face a barrage of decisions regarding childcare, which can contribute to decision fatigue.
Customer Support: Customer service representatives dealing with a high volume of inquiries may experience decision fatigue, which could affect the quality of their responses.
Travel Planning: When arranging trips with multiple itinerary options and accommodations, travelers might feel overwhelmed by decision fatigue.
Business Management: Entrepreneurs and business leaders constantly make strategic and operational decisions, which can lead to fatigue and potential errors in judgment.
Legal Proceedings: Judges, lawyers, and jurors involved in lengthy trials may experience decision fatigue, which could influence case outcomes.

Convergent thinking occurs when the solution to a problem can be found by applying established rules and logical reasoning. Whereas divergent thinking is an unstructured problem-solving method where participants are encouraged to develop many innovative ideas or solutions to a given problem. Where convergent thinking might work for larger, mature organizations where divergent thinking is more suited for startups and innovative companies.
The concept of cognitive biases was introduced and popularized by the work of Amos Tversky and Daniel Kahneman in 1972. Biases are seen as systematic errors and flaws that make humans deviate from the standards of rationality, thus making us inept at making good decisions under uncertainty.
Second-order thinking is a means of assessing the implications of our decisions by considering future consequences. Second-order thinking is a mental model that considers all future possibilities. It encourages individuals to think outside of the box so that they can prepare for every and eventuality. It also discourages the tendency for individuals to default to the most obvious choice.
Lateral thinking is a business strategy that involves approaching a problem from a different direction. The strategy attempts to remove traditionally formulaic and routine approaches to problem-solving by advocating creative thinking, therefore finding unconventional ways to solve a known problem. This sort of non-linear approach to problem-solving, can at times, create a big impact.
Bounded rationality is a concept attributed to Herbert Simon, an economist and political scientist interested in decision-making and how we make decisions in the real world. In fact, he believed that rather than optimizing (which was the mainstream view in the past decades) humans follow what he called satisficing.
The Dunning-Kruger effect describes a cognitive bias where people with low ability in a task overestimate their ability to perform that task well. Consumers or businesses that do not possess the requisite knowledge make bad decisions. What’s more, knowledge gaps prevent the person or business from seeing their mistakes.
Occam’s Razor states that one should not increase (beyond reason) the number of entities required to explain anything. All things being equal, the simplest solution is often the best one. The principle is attributed to 14th-century English theologian William of Ockham.
The Lindy Effect is a theory about the ageing of non-perishable things, like technology or ideas. Popularized by author Nicholas Nassim Taleb, the Lindy Effect states that non-perishable things like technology age – linearly – in reverse. Therefore, the older an idea or a technology, the same will be its life expectancy.
Antifragility was first coined as a term by author, and options trader Nassim Nicholas Taleb. Antifragility is a characteristic of systems that thrive as a result of stressors, volatility, and randomness. Therefore, Antifragile is the opposite of fragile. Where a fragile thing breaks up to volatility; a robust thing resists volatility. An antifragile thing gets stronger from volatility (provided the level of stressors and randomness doesn’t pass a certain threshold).
Systems thinking is a holistic means of investigating the factors and interactions that could contribute to a potential outcome. It is about thinking non-linearly, and understanding the second-order consequences of actions and input into the system.
Vertical thinking, on the other hand, is a problem-solving approach that favors a selective, analytical, structured, and sequential mindset. The focus of vertical thinking is to arrive at a reasoned, defined solution.
Maslow’s Hammer, otherwise known as the law of the instrument or the Einstellung effect, is a cognitive bias causing an over-reliance on a familiar tool. This can be expressed as the tendency to overuse a known tool (perhaps a hammer) to solve issues that might require a different tool. This problem is persistent in the business world where perhaps known tools or frameworks might be used in the wrong context (like business plans used as planning tools instead of only investors’ pitches).
The Peter Principle was first described by Canadian sociologist Lawrence J. Peter in his 1969 book The Peter Principle. The Peter Principle states that people are continually promoted within an organization until they reach their level of incompetence.
The straw man fallacy describes an argument that misrepresents an opponent’s stance to make rebuttal more convenient. The straw man fallacy is a type of informal logical fallacy, defined as a flaw in the structure of an argument that renders it invalid.
The Streisand Effect is a paradoxical phenomenon where the act of suppressing information to reduce visibility causes it to become more visible. In 2003, Streisand attempted to suppress aerial photographs of her Californian home by suing photographer Kenneth Adelman for an invasion of privacy. Adelman, who Streisand assumed was paparazzi, was instead taking photographs to document and study coastal erosion. In her quest for more privacy, Streisand’s efforts had the opposite effect.
As highlighted by German psychologist Gerd Gigerenzer in the paper “Heuristic Decision Making,” the term heuristic is of Greek origin, meaning “serving to find out or discover.” More precisely, a heuristic is a fast and accurate way to make decisions in the real world, which is driven by uncertainty.
The recognition heuristic is a psychological model of judgment and decision making. It is part of a suite of simple and economical heuristics proposed by psychologists Daniel Goldstein and Gerd Gigerenzer. The recognition heuristic argues that inferences are made about an object based on whether it is recognized or not.
The representativeness heuristic was first described by psychologists Daniel Kahneman and Amos Tversky. The representativeness heuristic judges the probability of an event according to the degree to which that event resembles a broader class. When queried, most will choose the first option because the description of John matches the stereotype we may hold for an archaeologist.
The take-the-best heuristic is a decision-making shortcut that helps an individual choose between several alternatives. The take-the-best (TTB) heuristic decides between two or more alternatives based on a single good attribute, otherwise known as a cue. In the process, less desirable attributes are ignored.
The bundling bias is a cognitive bias in e-commerce where a consumer tends not to use all of the products bought as a group, or bundle. Bundling occurs when individual products or services are sold together as a bundle. Common examples are tickets and experiences. The bundling bias dictates that consumers are less likely to use each item in the bundle. This means that the value of the bundle and indeed the value of each item in the bundle is decreased.
The Barnum Effect is a cognitive bias where individuals believe that generic information – which applies to most people – is specifically tailored for themselves.
First-principles thinking – sometimes called reasoning from first principles – is used to reverse-engineer complex problems and encourage creativity. It involves breaking down problems into basic elements and reassembling them from the ground up. Elon Musk is among the strongest proponents of this way of thinking.
The ladder of inference is a conscious or subconscious thinking process where an individual moves from a fact to a decision or action. The ladder of inference was created by academic Chris Argyris to illustrate how people form and then use mental models to make decisions.
Goodhart’s Law is named after British monetary policy theorist and economist Charles Goodhart. Speaking at a conference in Sydney in 1975, Goodhart said that “any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes.” Goodhart’s Law states that when a measure becomes a target, it ceases to be a good measure.
The Six Thinking Hats model was created by psychologist Edward de Bono in 1986, who noted that personality type was a key driver of how people approached problem-solving. For example, optimists view situations differently from pessimists. Analytical individuals may generate ideas that a more emotional person would not, and vice versa.
The Mandela effect is a phenomenon where a large group of people remembers an event differently from how it occurred. The Mandela effect was first described in relation to Fiona Broome, who believed that former South African President Nelson Mandela died in prison during the 1980s. While Mandela was released from prison in 1990 and died 23 years later, Broome remembered news coverage of his death in prison and even a speech from his widow. Of course, neither event occurred in reality. But Broome was later to discover that she was not the only one with the same recollection of events.
The bandwagon effect tells us that the more a belief or idea has been adopted by more people within a group, the more the individual adoption of that idea might increase within the same group. This is the psychological effect that leads to herd mentality. What in marketing can be associated with social proof.
Moore’s law states that the number of transistors on a microchip doubles approximately every two years. This observation was made by Intel co-founder Gordon Moore in 1965 and it become a guiding principle for the semiconductor industry and has had far-reaching implications for technology as a whole.
Disruptive innovation as a term was first described by Clayton M. Christensen, an American academic and business consultant whom The Economist called “the most influential management thinker of his time.” Disruptive innovation describes the process by which a product or service takes hold at the bottom of a market and eventually displaces established competitors, products, firms, or alliances.
Value migration was first described by author Adrian Slywotzky in his 1996 book Value Migration – How to Think Several Moves Ahead of the Competition. Value migration is the transferal of value-creating forces from outdated business models to something better able to satisfy consumer demands.
The bye-now effect describes the tendency for consumers to think of the word “buy” when they read the word “bye”. In a study that tracked diners at a name-your-own-price restaurant, each diner was asked to read one of two phrases before ordering their meal. The first phrase, “so long”, resulted in diners paying an average of $32 per meal. But when diners recited the phrase “bye bye” before ordering, the average price per meal rose to $45.
Groupthink occurs when well-intentioned individuals make non-optimal or irrational decisions based on a belief that dissent is impossible or on a motivation to conform. Groupthink occurs when members of a group reach a consensus without critical reasoning or evaluation of the alternatives and their consequences.
A stereotype is a fixed and over-generalized belief about a particular group or class of people. These beliefs are based on the false assumption that certain characteristics are common to every individual residing in that group. Many stereotypes have a long and sometimes controversial history and are a direct consequence of various political, social, or economic events. Stereotyping is the process of making assumptions about a person or group of people based on various attributes, including gender, race, religion, or physical traits.
Murphy’s Law states that if anything can go wrong, it will go wrong. Murphy’s Law was named after aerospace engineer Edward A. Murphy. During his time working at Edwards Air Force Base in 1949, Murphy cursed a technician who had improperly wired an electrical component and said, “If there is any way to do it wrong, he’ll find it.”
The law of unintended consequences was first mentioned by British philosopher John Locke when writing to parliament about the unintended effects of interest rate rises. However, it was popularized in 1936 by American sociologist Robert K. Merton who looked at unexpected, unanticipated, and unintended consequences and their impact on society.
Fundamental attribution error is a bias people display when judging the behavior of others. The tendency is to over-emphasize personal characteristics and under-emphasize environmental and situational factors.
Outcome bias describes a tendency to evaluate a decision based on its outcome and not on the process by which the decision was reached. In other words, the quality of a decision is only determined once the outcome is known. Outcome bias occurs when a decision is based on the outcome of previous events without regard for how those events developed.
Hindsight bias is the tendency for people to perceive past events as more predictable than they actually were. The result of a presidential election, for example, seems more obvious when the winner is announced. The same can also be said for the avid sports fan who predicted the correct outcome of a match regardless of whether their team won or lost. Hindsight bias, therefore, is the tendency for an individual to convince themselves that they accurately predicted an event before it happened.
