The replication crisis (or replicability crisis or reproducibility crisis) is, as of 2020, an ongoing methodological crisis in which it has been found that many scientific studies are difficult or impossible to replicate or reproduce. The replication crisis affects the social sciences and medicine most severely. The crisis has long-standing roots; the phrase was coined in the early 2010s as part of a growing awareness of the problem. The replication crisis represents an important body of research in the field of metascience.

Because the reproducibility of experimental results is an essential part of the scientific method, the inability to replicate the studies of others has potentially grave consequences for many fields of science in which significant theories are grounded on unreproducible experimental work. The replication crisis has been particularly widely discussed in the field of psychology and in medicine, where a number of efforts have been made to re-investigate classic results, to determine both the reliability of the results, and, if found to be unreliable, the reasons for the failure of replication.

🔗 Architecture

The Frankfurt kitchen was a milestone in domestic architecture, considered the forerunner of modern fitted kitchens, for it realised for the first time a kitchen built after a unified concept, designed to enable efficient work and to be built at low cost. It was designed in 1926 by Austrian architect Margarete Schütte-Lihotzky for architect Ernst May's social housing project New Frankfurt in Frankfurt, Germany. Some 10,000 units were built in the late 1920s in Frankfurt.

Mary Mallon (September 23, 1869 – November 11, 1938), also known as Typhoid Mary, was an Irish-born cook believed to have infected 53 people with typhoid fever, three of whom died, and the first person in the United States identified as an asymptomatic carrier of the disease, Salmonella typhi. Because she persisted in working as a cook, by which she exposed others to the disease, she was twice forcibly quarantined by authorities, eventually for the final two decades of her life. Mallon died after a total of nearly 30 years in isolation.

Everybody Draw Mohammed Day (or Draw Mohammed Day) was a 2010 event in support of artists threatened with violence for drawing representations of the Islamic prophet Muhammad. It stemmed from a protest against censorship of the American television show South Park episode "201", led by the show's distributor Comedy Central, in response to death threats that had been made against some of those responsible for two segments broadcast in April 2010. A drawing representing Mohammed was posted on the Internet on April 20, 2010, with a message suggesting that "everybody" create a drawing depicting Mohammad on May 20 in support of free speech.

U.S. cartoonist Molly Norris of Seattle, Washington created the artwork in reaction to Internet death threats that had been made against animators Trey Parker and Matt Stone for depicting Muhammad in an episode of South Park. Postings on RevolutionMuslim.com (under the pen name Abu Talha al-Amrikee; later identified as Zachary Adam Chesser) had said that Parker and Stone could wind up like Theo van Gogh, a Dutch filmmaker who was stabbed and shot to death.

Norris claimed that, if people draw pictures of Muhammad, radical Islamist terrorists would not be able to murder them all, and threats to do so would become unrealistic. Within a week, Norris' idea became popular on Facebook, was supported by numerous bloggers, and generated coverage on the blog websites of major U.S. newspapers. As the publicity mounted, Norris and the man who created the first Facebook page promoting the May 20 event disassociated themselves from it. Nonetheless, planning for the protest continued with others "taking up the cause". Facebook had an "Everybody Draw Mohammed Day" page, which grew to over 100,000 participants (101,870 members by May 20). A protest page on Facebook against the initiative named "Against ‘Everybody Draw Mohammed Day'" attracted slightly more supporters (106,000 by May 20). Subsequently, Facebook was temporarily blocked by Pakistan; the ban was lifted after Facebook agreed to block the page for users in India and Pakistan.

In the media, Everybody Draw Mohammed Day attracted support from commentators who felt that the campaign represented important issues of freedom of speech, and the need to stand up for this freedom.

In politics and economics, a Potemkin village is any construction (literal or figurative) whose sole purpose is to provide an external façade to a country which is faring poorly, making people believe that the country is faring better, although statistics and charts would state otherwise. The term comes from stories of a fake portable village built solely to impress Empress Catherine II by her former lover Grigory Potemkin, during her journey to Crimea in 1787. While modern historians claim accounts of this portable village are exaggerated, the original story was that Potemkin erected phony portable settlements along the banks of the Dnieper River in order to impress the Russian Empress; the structures would be disassembled after she passed, and re-assembled farther along her route to be viewed again as if another example. The term is a translation of the Russian: потёмкинские деревни (IPA: /pɐˈtʲɵmkʲɪnskʲɪɪ dʲɪˈrʲɛvnʲɪ/; romanization: potyómkinskiye derévni).

Cuckoo hashing is a scheme in computer programming for resolving hash collisions of values of hash functions in a table, with worst-case constant lookup time. The name derives from the behavior of some species of cuckoo, where the cuckoo chick pushes the other eggs or young out of the nest when it hatches; analogously, inserting a new key into a cuckoo hashing table may push an older key to a different location in the table.

Thinking, Fast and Slow is a 2011 popular science book by the Israeli-American psychologist Daniel Kahneman. Its main thesis is a differentiation between two modes of thought: "System 1" is fast, instinctive and emotional; "System 2" is slower, more deliberative, and more logical.

The book delineates rational and non-rational motivations or triggers associated with each type of thinking process, and how they complement each other, starting with Kahneman's own research on loss aversion. From framing choices to people's tendency to replace a difficult question with one that is easy to answer, the book summarizes several decades of research to suggest that people have too much confidence in human judgment. Kahneman performed his own research, often in collaboration with the psychologist Amos Tversky, which enriched his experience to write the book. It covers different phases of his career: his early work concerning cognitive biases, his work on prospect theory and happiness, and with the Israel Defense Forces.

Jason Zweig, a columnist at The Wall Street Journal, helped write and research the book over two years. The book was a New York Times bestseller and was the 2012 winner of the American National Academies Communication Award for best creative work that helps the public understanding of topics in behavioral science, engineering and medicine. The integrity of some priming studies cited in the book has been called into question in the midst of the psychological replication crisis.

The Ocoee massacre was a white mob attack on African-American residents in northern Ocoee, Florida, which occurred on November 2, 1920, the day of the U.S. presidential election. The town is in Orange County near Orlando. Most estimates total 30–35 Blacks killed, although as many as 50 African Americans may have been killed during the massacre. Most African-American-owned buildings and residences in northern Ocoee were burned to the ground. Other African Americans living in southern Ocoee were later killed or driven out on threat of more violence. Ocoee essentially became an all-white town. The massacre has been described as the "single bloodiest day in modern American political history".

The attack started after efforts to suppress black voting. In Ocoee and across the state, various black organizations had been conducting voter registration drives for a year. Blacks had essentially been disfranchised in Florida since the beginning of the 20th century. Mose Norman, a prosperous African-American farmer, tried to vote but was turned away twice on Election Day. Norman was among those working on the voter drive. A white mob surrounded the home of Julius "July" Perry, where Norman was thought to have taken refuge. After Perry drove away the white mob with gunshots, killing two men and wounding one who tried to break into his house, the mob called for reinforcements from Orlando and Orange County. The whites laid waste to the African-American community in northern Ocoee and eventually killed Perry. They took his body to Orlando and hanged it from a lightpost to intimidate other blacks. Norman escaped, never to be found. Hundreds of other African Americans fled the town, leaving behind their homes and possessions.

Since the 1970's, several deputies of the Los Angeles County Sheriff's Department have formed gangs in which membership is exclusive to certain sheriff's deputies, often along ethnic lines, and requires certain acts, such as police violence (particularly against people of color), in order to be initiated into said gang. Members are often tattooed and are expected to maintain the blue wall of silence (i.e. not snitch or report misconduct on or about other officers), fabricate evidence, engage in police corruption, and engage in criminal activity such as vandalism and homicide, among other things. Historically, almost all instances of deputy gang violence has either been ignored by the Los Angeles County District Attorney's Office or the office has stood by the members of the deputy gangs, alongside the tolerance or assistance of the county sheriff. Although not unique to the Los Angeles County Sheriff's Department, it suffers from the most prolific case of the existence of law enforcement gangs in the state.
