10,000-Hour Rule

The 10,000-Hour Rule suggests that dedicating around 10,000 hours of deliberate practice can lead to expertise in a particular domain. It highlights the significance of focused and structured learning for skill development and expert recognition, although debates exist about its universal applicability. This concept finds applications in various fields, including education and personal development.

Understanding the 10,000-Hour Rule

  • Origins: The concept of the 10,000-Hour Rule was popularized by Malcolm Gladwell in his book “Outliers,” published in 2008. Gladwell claimed that 10,000 hours of practice was a common factor among successful individuals, from musicians to athletes to computer programmers.
  • Ericsson’s Research: The foundation of the rule can be traced back to the research of psychologist Anders Ericsson, who studied the practice habits of expert violinists. He found that the best violinists had accumulated an average of 10,000 hours of practice by the age of 20.

Key Principles of the 10,000-Hour Rule

  • Deliberate Practice: The rule emphasizes that not all practice is equal. It should be deliberate, focused, and challenging. Simply repeating tasks without improvement does not lead to mastery.
  • Time Investment: Mastery is not achieved quickly or easily. The rule underscores the importance of dedicating a substantial amount of time to practice.
  • Domain Specificity: While the rule has been applied to various fields, it acknowledges that the required hours of practice may vary depending on the complexity of the skill or domain.

Real-World Applications of the 10,000-Hour Rule

  • Musical Excellence: Many renowned musicians, such as the Beatles and Mozart, are often cited as examples of individuals who accumulated extensive practice hours before achieving greatness in their respective fields.
  • Sports Achievements: Athletes like Tiger Woods and Serena Williams are frequently mentioned in the context of the rule, as they invested substantial time in honing their skills from a young age.
  • Expertise in Professions: Professionals like doctors, lawyers, and software engineers often undergo years of rigorous training and practice to reach a level of expertise consistent with the 10,000-Hour Rule.

Criticisms of the 10,000-Hour Rule

  • Oversimplification: Critics argue that the rule oversimplifies the path to expertise by focusing solely on the quantity of practice hours. Other factors, such as natural talent, quality of instruction, and access to resources, also play a significant role.
  • Variance in Domains: The rule’s application to different domains is questioned. Some skills may require more or fewer hours to master, and generalizing the 10,000-hour benchmark may not be accurate.
  • Misinterpretation: The rule has been misinterpreted as a guarantee of success. Simply accumulating hours of practice does not ensure mastery; the quality and nature of practice are equally important.

Significance of the 10,000-Hour Rule

  • Motivation: The rule can serve as motivation for individuals striving for mastery in their chosen fields. Knowing that expertise is attainable through dedicated practice encourages persistence.
  • Guidance: While the rule has limitations, it provides a rough estimate of the time and effort required to become highly skilled in a particular area. This can help individuals set realistic expectations.
  • Redefining Talent: The rule challenges the notion of innate talent and highlights the role of effort and practice in achieving excellence. It promotes a growth mindset, emphasizing that skills can be developed over time.

FrameworkDescriptionWhen to Apply
Deliberate PracticeDeliberate Practice: Deliberate practice is a concept popularized by psychologist Anders Ericsson, which emphasizes focused and structured efforts aimed at skill improvement. It involves engaging in activities specifically designed to enhance performance, receiving immediate feedback, and continuously refining one’s abilities through repetition and refinement. The 10,000-hour rule is often associated with deliberate practice, suggesting that achieving expertise in a particular domain requires approximately 10,000 hours of deliberate practice. Deliberate practice is characterized by goal-setting, breaking down complex skills into manageable components, and engaging in purposeful practice sessions that target weaknesses and push individuals beyond their comfort zones. By adopting deliberate practice strategies, individuals can accelerate skill development, overcome plateaus, and achieve mastery in various fields, from sports and music to business and academia. Recognizing the principles of deliberate practice can inform training programs, coaching methodologies, and personal development efforts aimed at cultivating expertise and excellence.Accelerating skill development, overcoming plateaus, or achieving mastery in various fields by adopting deliberate practice strategies that emphasize focused and structured efforts aimed at skill improvement, in sports, music, business, or academic contexts where individuals aim to excel and achieve expertise through purposeful practice and feedback, in designing training programs or coaching methodologies that facilitate skill acquisition and mastery by breaking down complex skills into manageable components and targeting weaknesses through deliberate practice sessions.
Expertise DevelopmentExpertise Development: Expertise development refers to the process through which individuals acquire specialized knowledge, skills, and abilities in a particular domain through deliberate practice and experience. The 10,000-hour rule is often cited as a benchmark for achieving expertise, suggesting that extensive practice and immersion in an activity are necessary for mastery. Expertise development involves progressive refinement and integration of knowledge and skills over time, as individuals engage in deliberate practice, receive feedback, and adapt their strategies to improve performance. Achieving expertise requires not only quantity but also quality of practice, as individuals must engage in focused and purposeful efforts aimed at skill improvement. By understanding the dynamics of expertise development, educators, trainers, and practitioners can design learning experiences, training programs, and performance interventions that facilitate skill acquisition and mastery in various domains. Strategies such as scaffolding, modeling, and reflective practice can support individuals’ progression towards expertise by providing structured opportunities for learning, practice, and feedback.Facilitating skill acquisition and mastery in various domains by designing learning experiences, training programs, or performance interventions that support individuals’ progression towards expertise, in education, training, or professional development contexts where individuals aim to develop specialized knowledge and skills through deliberate practice and experience, in designing interventions or coaching methodologies that aim to accelerate expertise development by providing structured opportunities for learning, practice, and feedback.
Skill Acquisition ModelsSkill Acquisition Models: Skill acquisition models provide theoretical frameworks for understanding how individuals learn and develop skills over time. The 10,000-hour rule aligns with skill acquisition models, such as the stages of learning model or the expertise acquisition model, which emphasize the progression from novice to expert through deliberate practice and experience. Skill acquisition models typically involve stages such as cognitive, associative, and autonomous learning, where individuals gradually refine their abilities and automate their performance through repeated practice and feedback. The 10,000-hour rule reflects the cumulative nature of skill acquisition, suggesting that achieving expertise requires sustained effort and immersion in an activity. By applying skill acquisition models, educators, coaches, and practitioners can tailor instruction, training, and feedback to individuals’ learning needs and developmental stages, fostering skill acquisition and mastery across various domains. Understanding the principles of skill acquisition can inform instructional design, curriculum development, and performance enhancement strategies aimed at optimizing learning and skill development outcomes.Tailoring instruction, training, or feedback to individuals’ learning needs and developmental stages by applying skill acquisition models that emphasize the progression from novice to expert through deliberate practice and experience, in education, coaching, or performance enhancement contexts where individuals aim to develop skills and expertise over time, in designing instructional strategies or training programs that align with individuals’ learning trajectories and support their progression towards mastery by providing appropriate guidance, practice, and feedback.
Expert Performance ParadigmExpert Performance Paradigm: The expert performance paradigm is a theoretical framework proposed by psychologist Anders Ericsson, which focuses on understanding the factors underlying exceptional performance and expertise. The 10,000-hour rule is a central tenet of the expert performance paradigm, suggesting that extensive practice is necessary for individuals to attain elite levels of performance in their respective domains. The paradigm emphasizes the role of deliberate practice, domain-specific knowledge, and effective learning strategies in fostering expertise. According to the expert performance paradigm, achieving mastery requires not only quantity but also quality of practice, as individuals must engage in purposeful and focused efforts aimed at skill improvement. By embracing the principles of the expert performance paradigm, educators, coaches, and practitioners can optimize training, instruction, and performance interventions to support individuals’ development of expertise and excellence. Strategies such as deliberate practice, feedback mechanisms, and mental representations can enhance skill acquisition and performance across various domains, from sports and music to business and medicine.Optimizing training, instruction, or performance interventions to support individuals’ development of expertise and excellence by embracing the principles of the expert performance paradigm, in education, coaching, or professional development contexts where individuals aim to achieve elite levels of performance in their respective domains, in designing interventions or training programs that foster skill acquisition and mastery through deliberate practice, feedback mechanisms, and effective learning strategies aligned with the principles of the expert performance paradigm.
Mastery Learning ApproachMastery Learning Approach: Mastery learning is an instructional approach that emphasizes ensuring all learners achieve a predetermined level of mastery or proficiency before progressing to more advanced content or skills. The 10,000-hour rule aligns with the mastery learning approach, as it underscores the importance of extensive practice and proficiency attainment in skill development. Mastery learning involves breaking down complex skills or concepts into manageable units, providing targeted instruction and practice opportunities, and offering personalized feedback and support to learners. By allowing learners to progress at their own pace and focusing on mastery of foundational knowledge and skills, mastery learning facilitates deep understanding and retention of content. Mastery learning strategies, such as formative assessment, differentiated instruction, and corrective feedback, can support individuals’ progression towards expertise in various domains. By implementing mastery learning principles, educators, trainers, and instructional designers can create learning environments that optimize skill acquisition, retention, and transfer, enabling learners to achieve mastery and proficiency in their chosen fields.Creating learning environments that optimize skill acquisition, retention, or transfer by implementing mastery learning principles that emphasize ensuring all learners achieve a predetermined level of mastery or proficiency, in education, training, or professional development contexts where individuals aim to develop expertise and proficiency in specific domains, in designing instructional strategies or interventions that provide targeted instruction, practice, and feedback aligned with mastery learning principles to support learners’ progression towards mastery and proficiency.
Flow State TheoryFlow State Theory: Flow state theory, proposed by psychologist Mihaly Csikszentmihalyi, describes a state of optimal experience characterized by intense focus, deep engagement, and heightened performance. The 10,000-hour rule intersects with flow state theory, as achieving expertise often involves experiencing flow states during deliberate practice and skill acquisition. Flow states occur when individuals are fully immersed in a challenging activity that matches their skills, leading to feelings of enjoyment, mastery, and timelessness. The 10,000-hour rule reflects the cumulative nature of skill development, suggesting that extensive practice is necessary to reach a level where flow states become more frequent and sustained. By understanding flow state theory, educators, coaches, and practitioners can create conditions that foster flow experiences and enhance skill acquisition and performance. Strategies such as setting clear goals, providing immediate feedback, and balancing challenge and skill level can promote flow states and optimize learning outcomes across various domains. Recognizing the role of flow in expertise development can inform instructional design, training programs, and performance interventions aimed at maximizing individuals’ engagement, motivation, and achievement.Creating conditions that foster flow experiences and enhance skill acquisition or performance by understanding flow state theory, in education, coaching, or performance enhancement contexts where individuals aim to achieve optimal experiences and peak performance, in designing learning environments or training programs that promote flow states through clear goals, immediate feedback, and balanced challenge levels, in implementing strategies or interventions that optimize engagement, motivation, and achievement by leveraging flow state principles in skill development and performance enhancement efforts.
Chunking and Cognitive Load TheoryChunking and Cognitive Load Theory: Chunking is a cognitive process whereby information is organized into meaningful units or chunks, facilitating memory and learning. Cognitive load theory describes how the cognitive load imposed by learning tasks affects individuals’ ability to process information and learn effectively. The 10,000-hour rule relates to chunking and cognitive load theory, as extensive practice involves organizing and automating skills into cognitive chunks to reduce cognitive load and enhance performance. Chunking allows individuals to process complex information more efficiently, freeing up cognitive resources for higher-order thinking and problem-solving. By chunking information into manageable units and practicing them repeatedly, individuals can build expertise and fluency in a domain. Cognitive load theory suggests that minimizing extraneous cognitive load and optimizing intrinsic and germane cognitive load can enhance learning outcomes. By applying chunking and cognitive load principles, educators, trainers, and instructional designers can design learning experiences, materials, and assessments that support skill acquisition and mastery in various domains. Techniques such as scaffolding, worked examples, and spaced practice can help learners build cognitive chunks and optimize learning efficiency.Designing learning experiences, materials, or assessments that support skill acquisition and mastery by applying chunking and cognitive load principles, in education, training, or professional development contexts where individuals aim to develop expertise and fluency in specific domains, in designing instructional strategies or interventions that optimize learning efficiency by minimizing extraneous cognitive load and promoting effective chunking and practice, in implementing techniques or approaches that support learners’ cognitive processing and skill development through organized, scaffolded, or spaced practice aligned with chunking and cognitive load principles.
Feedback and Error CorrectionFeedback and Error Correction: Feedback and error correction play essential roles in skill acquisition and expertise development by providing learners with information about their performance and guiding their improvement efforts. The 10,000-hour rule emphasizes the importance of feedback and error correction in deliberate practice, as individuals must receive timely and informative feedback to refine their skills and overcome weaknesses. Feedback can take various forms, including verbal guidance, corrective instructions, and performance evaluations, and should be tailored to individuals’ learning needs and goals. Effective feedback enables learners to identify errors, adjust their strategies, and monitor their progress towards mastery. Error correction involves recognizing and correcting mistakes during practice sessions, reinforcing correct behaviors, and addressing misconceptions or gaps in understanding. By providing systematic feedback and error correction mechanisms, educators, coaches, and mentors can support learners’ skill development and performance improvement across various domains. Techniques such as modeling, peer review, and self-assessment can enhance feedback delivery and error correction processes, fostering continuous learning and skill refinement.Supporting learners’ skill development and performance improvement by providing systematic feedback and error correction mechanisms, in education, coaching, or professional development contexts where individuals aim to refine their skills and overcome weaknesses, in designing interventions or coaching methodologies that facilitate feedback delivery and error correction through techniques such as modeling, peer review, or self-assessment, in implementing strategies or approaches that promote continuous learning and skill refinement through targeted feedback and error correction aligned with learners’ needs and goals.
Metacognition and Self-Regulated LearningMetacognition and Self-Regulated Learning: Metacognition refers to individuals’ awareness and understanding of their own thought processes, strategies, and learning behaviors. Self-regulated learning involves managing and controlling one’s cognitive processes, motivation, and behavior to achieve learning goals. The 10,000-hour rule intersects with metacognition and self-regulated learning, as achieving expertise requires individuals to engage in deliberate practice, monitor their progress, and adjust their learning strategies accordingly. Metacognitive skills such as goal-setting, planning, monitoring, and reflection are essential for effective self-regulated learning and skill development. By cultivating metacognition and self-regulated learning skills, individuals can become more autonomous, adaptive, and efficient learners across various domains. Strategies such as goal-setting, self-monitoring, and self-reflection can enhance metacognitive awareness and promote self-regulated learning behaviors. Educators, trainers, and mentors can foster metacognition and self-regulated learning by providing opportunities for reflection, goal-setting, and self-assessment, empowering learners to take ownership of their learning and development. Recognizing the role of metacognition in expertise development can inform instructional design, coaching practices, and performance interventions aimed at cultivating lifelong learning skills and adaptive expertise.Cultivating metacognition and self-regulated learning skills to empower individuals as autonomous, adaptive, and efficient learners, in education, training, or professional development contexts where individuals aim to develop expertise and mastery in specific domains, in designing learning experiences or interventions that promote metacognitive awareness and self-regulated learning behaviors through goal-setting, monitoring, and reflection, in implementing strategies or approaches that foster learners’ ownership of their learning and development by providing opportunities for metacognitive skill development aligned with their goals and aspirations.

Connected Thinking Frameworks

Convergent vs. Divergent Thinking

convergent-vs-divergent-thinking
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.

Critical Thinking

critical-thinking
Critical thinking involves analyzing observations, facts, evidence, and arguments to form a judgment about what someone reads, hears, says, or writes.

Biases

biases
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

second-order-thinking
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

lateral-thinking
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

bounded-rationality
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.

Dunning-Kruger Effect

dunning-kruger-effect
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

occams-razor
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.

Lindy Effect

lindy-effect
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

antifragility
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

systems-thinking
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

vertical-thinking
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

einstellung-effect
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).

Peter Principle

peter-principle
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.

Straw Man Fallacy

straw-man-fallacy
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.

Streisand Effect

streisand-effect
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.

Heuristic

heuristic
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.

Recognition Heuristic

recognition-heuristic
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.

Representativeness Heuristic

representativeness-heuristic
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.

Take-The-Best Heuristic

take-the-best-heuristic
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.

Bundling Bias

bundling-bias
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.

Barnum Effect

barnum-effect
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

first-principles-thinking
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.

Ladder Of Inference

ladder-of-inference
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

goodharts-law
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.

Six Thinking Hats Model

six-thinking-hats-model
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.

Mandela Effect

mandela-effect
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.

Crowding-Out Effect

crowding-out-effect
The crowding-out effect occurs when public sector spending reduces spending in the private sector.

Bandwagon Effect

bandwagon-effect
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

moores-law
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

disruptive-innovation
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

value-migration
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.

Bye-Now Effect

bye-now-effect
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

groupthink
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.

Stereotyping

stereotyping
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

murphys-law
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.”

Law of Unintended Consequences

law-of-unintended-consequences
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

fundamental-attribution-error
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

outcome-bias
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

hindsight-bias
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.
