The great man theory is an approach to the study of history popularised in the 19th century according to which history can be largely explained by the impact of great men, or heroes: highly influential and unique individuals who, due to their natural attributes, such as superior intellect, heroic courage, extraordinary leadership abilities, or divine inspiration, have a decisive historical effect. The theory is primarily attributed to the Scottish essayist, historian, and philosopher Thomas Carlyle, who gave a series of lectures on heroism in 1840, later published as On Heroes, Hero-Worship, & the Heroic in History, in which he states:
Universal History, the history of what man has accomplished in this world, is at bottom the History of the Great Men who have worked here. They were the leaders of men, these great ones; the modellers, patterns, and in a wide sense creators, of whatsoever the general mass of men contrived to do or to attain; all things that we see standing accomplished in the world are properly the outer material result, the practical realisation and embodiment, of Thoughts that dwelt in the Great Men sent into the world: the soul of the whole world's history, it may justly be considered, were the history of these.
In criminology, the broken windows theory states that visible signs of crime, antisocial behavior, and civil disorder create an urban environment that encourages further crime and disorder, including serious crimes. The theory suggests that policing methods that target minor crimes such as vandalism, loitering, public drinking and fare evasion help to create an atmosphere of order and lawfulness.
Duncan James Watts is a computational social scientist and a professor at the University of Pennsylvania. He was formerly a principal researcher at Microsoft Research in New York City, and is known for his work on small-world networks.
The small-world experiment comprised several experiments conducted by Stanley Milgram and other researchers examining the average path length for social networks of people in the United States. The research was groundbreaking in that it suggested that human society is a small-world-type network characterized by short path-lengths. The experiments are often associated with the phrase "six degrees of separation", although Milgram did not use this term himself.

A theory regarding the effect of legalized abortion on crime is a controversial hypothesis about the reduction in crime in the decades following the legalization of abortion. Proponents argue that the availability of abortion resulted in fewer births of children at the highest risk of committing crime. The earliest research suggesting such an effect was a 1966 study in Sweden. In 2001, Steven Levitt of the University of Chicago and John Donohue of Yale University argued, citing their research and earlier studies, that children who are unwanted or whose parents cannot support them are likelier to become criminals. This idea was further popularized by its inclusion in the book Freakonomics, which Levitt co-wrote.

In a view of the future, a wild card is a low-probability, large-effect event. This concept may be introduced into anticipatory decision-making activity in order to increase the ability of organizations and governments to adapt to surprises arising in turbulent (business) environments. Such sudden and unique incidents might constitute turning points in the evolution of a certain trend or system. Wild cards may or may not be announced by weak signals, which are incomplete and fragmented data from which foresight information might be inferred.
Practice is the act of rehearsing a behavior 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".

Made to Stick: Why Some Ideas Survive and Others Die is a book by brothers Chip and Dan Heath published by Random House on January 2, 2007. The book expands upon the idea of "stickiness" popularized by Malcolm Gladwell in The Tipping Point, seeking to explain what makes an idea or concept memorable or interesting. The Heaths employed a style similar to Gladwell's by including a number of stories and case studies followed by general principles.
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.

Six degrees of separation is the idea that all people are six or fewer social connections away from each other. As a result, a chain of "friend of a friend" statements can be made to connect any two people in a maximum of six steps. It is also known as the six handshakes rule.
