An expert is somebody who has a broad and deep understanding and competence in terms of knowledge, skill and experience through practice and education in a particular field or area of study. Informally, an expert is someone widely recognized as a reliable source of technique or skill whose faculty for judging or deciding rightly, justly, or wisely is accorded authority and status by peers or the public in a specific well-distinguished domain. An expert, more generally, is a person with extensive knowledge or ability based on research, experience, or occupation and in a particular area of study. Experts are called in for advice on their respective subject, but they do not always agree on the particulars of a field of study. An expert can be believed, by virtue of credentials, training, education, profession, publication or experience, to have special knowledge of a subject beyond that of the average person, sufficient that others may officially rely upon the individual's opinion on that topic. Historically, an expert was referred to as a sage. The individual was usually a profound thinker distinguished for wisdom and sound judgment.
An aptitude is a component of a competence to do a certain kind of work at a certain level. Outstanding aptitude can be considered "talent". Aptitude is inborn potential to perform certain kinds of activities, whether physical or mental, and whether developed or undeveloped. Aptitude is often contrasted with skills and abilities, which are developed through learning. The mass term ability refers to components of competence acquired through a combination of both aptitude and skills.

In cognitive psychology, chunking is a process by which small individual pieces of a set of information are bound together to create a meaningful whole later on in memory. The chunks, by which the information is grouped, are meant to improve short-term retention of the material, thus bypassing the limited capacity of working memory and allowing the working memory to be more efficient. A chunk is a collection of basic units that are strongly associated with one another, and have been grouped together and stored in a person's memory. These chunks can be retrieved easily due to their coherent grouping. It is believed that individuals create higher-order cognitive representations of the items within the chunk. The items are more easily remembered as a group than as the individual items themselves. These chunks can be highly subjective because they rely on an individual's perceptions and past experiences, which are linked to the information set. The size of the chunks generally ranges from two to six items but often differs based on language and culture.
Blink: The Power of Thinking Without Thinking (2005) is Malcolm Gladwell's second book. It presents in popular science format research from psychology and behavioral economics on the adaptive unconscious: mental processes that work rapidly and automatically from relatively little information. It considers both the strengths of the adaptive unconscious, for example in expert judgment, and its pitfalls, such as prejudice and stereotypes.
The title mnemonist refers to an individual with the ability to remember and recall unusually long lists of data, such as unfamiliar names, lists of numbers, entries in books, etc. Some mnemonists also memorize texts such as long poems, speeches, or even entire books of fiction or non-fiction. The term is derived from the term mnemonic, which refers to a strategy to support remembering, but not all mnemonists report using mnemonics. Mnemonists may have superior innate ability to recall or remember, in addition to relying on techniques.

Practice is the act of rehearsing a behaviour repeatedly, to help learn and eventually master a skill. The word derives from the Greek "πρακτική" (praktike), feminine of "πρακτικός" (praktikos), "fit for or concerned with action, practical", and that from the verb "πράσσω" (prasso), "to achieve, bring about, effect, accomplish".

Outliers: The Story of Success is the non-fiction book written by Malcolm Gladwell and published by Little, Brown and Company on November 18, 2008. In Outliers, Gladwell examines the factors that contribute to high levels of success. To support his thesis, he examines why the majority of Canadian ice hockey players are born in the first few months of the calendar year, how Microsoft co-founder Bill Gates achieved his extreme wealth, how the Beatles became one of the most successful musical acts in human history, how two people with exceptional intelligence—Christopher Langan and J. Robert Oppenheimer—end up with such vastly different fortunes, how Joseph Flom built Skadden, Arps, Slate, Meagher & Flom into one of the most successful law firms in the world, and how cultural differences play a large part in perceived intelligence and rational decision making. Throughout the publication, Gladwell repeatedly mentions the "10,000-Hour Rule", claiming that the key to achieving world-class expertise in any skill, is, to a large extent, a matter of practicing the correct way, for a total of around 10,000 hours, though the authors of the original study have disputed Gladwell's usage.
The plateau effect is a phenomenon that lessens the effectiveness of once effective measures over time. An example of the plateau effect is when someone's exercise fails to be as effective as in the past, similar to the concept of diminishing returns. A person enters into a period where there is no improvement or a decrease in performance.
In psychology, grit is a positive, non-cognitive trait based on a person's perseverance of effort combined with their passion for a particular long-term goal or end state. This perseverance of effort helps people overcome obstacles or challenges to accomplishment and drives people to achieve.

Bush administration, including the verbiage and public presentations used in the War on Terror. The author argues al-Qaeda is not part of Islam but is instead a dangerous religious cult. Nance writes the United States should commit to better education with a public relations campaign to encourage traditional believers in Islam around the world to denounce al-Qaeda.
David Zachary (Zach) Hambrick is a psychology professor at Michigan State University, known for his research on the effects of practice on proficiency in various skills. Hambrick's research has concluded that practice is important in explaining ability in fields such as chess, music, and academics, but less so than argued by other psychologists, notably K. Anders Ericsson. Hambrick contends that, in addition to amount of practice, working memory capacity is associated with better performance on a wide variety of tasks.

Range: Why Generalists Triumph in a Specialized World is a 2019 book by David Epstein in which he expands on the points from his previous book The Sports Gene: Inside the Science of Extraordinary Athletic Performance to make a more general argument against overspecialization. In the book, he argues that range – defined as more diverse experience across multiple fields – is more relevant in today's society than specialization because the wicked problems of the modern world require bridging experience and knowledge from multiple fields to foster solutions.

The Bomber Mafia: A Dream, a Temptation, and the Longest Night of the Second World War is a 2021 book by Malcolm Gladwell that examines the US Bomber Mafia of World War II, which advocated precision aerial bombing as a means to win a war. Gladwell stated the audiobook for The Bomber Mafia came about as an expansion of material from his podcast Revisionist History, and that the print book originated from the audiobook. The book follows the Bomber Mafia, especially Major General Haywood S. Hansell, and the development of a high-altitude precision aerial bombardment strategy in World War II as a means to limit casualties. After difficulties in applying the Bomber Mafia's theoretical strategy, Major General Hansell was replaced by Major General Curtis LeMay, who utilized tactical changes such as attacking Japanese population centers with napalm to ensure a Japanese surrender. Upon release, The Bomber Mafia was met with mixed reviews, with reviewers praising its audiobook version but criticizing the book for a lack of accuracy and for being light on details.
