Make America Great Again

From Wikipedia, the free encyclopedia

"Make America Great Again" (MAGA, US: /ˈmæɡə/) is an American political slogan most recently popularized by Donald Trump during his presidential campaigns in 2016, 2020, and 2024. "MAGA" is also used to refer to Trump's ideology, political base, or to an individual or group of individuals from within that base. The slogan became a pop culture phenomenon, seeing widespread use and spawning numerous variants in the arts, entertainment and politics, being used by both supporters and opponents of Trump's presidency and as the name of the super PAC Make America Great Again Inc.

Originally used by Ronald Reagan as a campaign slogan in his 1980 presidential campaign ("Let's Make America Great Again"), it was adopted by Trump in 2015. It has been described as a slogan representing American exceptionalism and promoting an idealized or romanticized American past. While some scholars, journalists, and commentators have called the slogan a loaded phrase representing racism, regarding it as dog-whistle politics and coded language that excludes certain groups, others regard the slogan as patriotic and positive.

History

Ronald Reagan

"Let's make America great again" was famously used in Ronald Reagan's 1980 presidential campaign. At the time, the United States was suffering from a worsening economy at home marked by stagflation. Using the country's economic distress as a springboard for his campaign, Reagan used the slogan to stir a sense of patriotism among the electorate. During his acceptance speech at the 1980 Republican National Convention, Reagan said, "For those without job opportunities, we'll stimulate new opportunities, particularly in the inner cities where they live. For those who've abandoned hope, we'll restore hope and we'll welcome them into a great national crusade to make America great again."

Bill Clinton

The phrase was used in speeches by Bill Clinton during his 1992 presidential campaign. President Clinton also used the phrase in a radio commercial aired for wife Hillary Clinton's 2008 presidential primary campaign. During the 2016 electoral campaign, in which his wife was running against Trump, he suggested that Trump's version, used as a campaign rallying cry, was a message to White Southerners that Trump was promising to "give you an economy you had 50 years ago, and ... move you back up on the social totem pole and other people down."

Use by Donald Trump

In December 2011, following speculation that he would challenge sitting president Barack Obama in the 2012 United States presidential election, Trump released a statement in which he said he was unwilling to rule out running as a presidential candidate in the future, explaining "I must leave all of my options open because, above all else, we must make America great again." In December 2011, he also published a book using as a subtitle the similar phrase "Making America #1 Again", which in a 2015 reissue was changed to "Make America Great Again!" On January 1, 2012, a group of Trump supporters filed paperwork with the Texas secretary of state's office to create the "Make America Great Again Party", which would have allowed Trump to be that party's nominee if he had decided to become a third-party candidate in the presidential election.

Trump began using the slogan formally on November 7, 2012, the day after Barack Obama won his re-election against Mitt Romney. Trump used the slogan in an August 2013 interview with Jonathan Karl. By his own account, he first considered "We Will Make America Great", but did not feel like it had the right "ring" to it. "Make America Great" was his next slogan idea, but upon further reflection, he felt that it was a slight to America because it implied that America was never great. He eventually selected the phrase "Make America Great Again", later claiming that he was unaware of Reagan's use in 1980 until 2015, but noted that "he didn't trademark it." On November 12, he signed an application with the United States Patent and Trademark Office requesting exclusive rights to use the slogan for political purposes. It was registered as a service mark on July 14, 2015, after Trump formally began his 2016 presidential campaign and demonstrated that he was using the slogan for the purpose stated on the application.

However, Trump did not trademark the phrase in commerce. On August 5, 2015, radio personality Bobby Bones took note of this and successfully filed a trademark for the phrase's use in commerce. Two days later Bones tweeted at Trump, offering the use of his slogan back in exchange for a $100,000 donation to the St. Jude Children's Research Hospital. On October 29, Bones followed up the tweet with an image of a check from the Trump Organization. The amount on the check was undisclosed and Bones said that Trump could "have [his] slogan back".

Following Trump's first election, the website of his presidential transition was established at greatagain.gov. Trump said in 2017 and 2018 that the slogan of his 2020 reelection campaign would be "Keep America Great" and he sought to trademark it. However, Trump's 2020 campaign continued to use the "Make America Great Again" slogan. Trump's vice president, Mike Pence, used the phrase "make America great again, again" in his 2020 Republican National Convention speech, garnering ridicule for implying that Trump's first term had failed. In late 2021, this phrase became the name of a pro-Trump Super-PAC, which was also mocked. A 2020 executive order, titled "Promoting Beautiful Federal Civic Architecture", was nicknamed "Make Federal Buildings Beautiful Again" by proponents and the press.

Less than a week after Trump left office, he spoke to advisors about possibly establishing a third party, which he suggested might be named either the "Patriot Party" or "Make America Great Again Party". In his first few days out of office, he also supported Arizona state party chairwoman Kelli Ward, who likewise called for the creation of a "MAGA Party". In late January 2021, the former president viewed the proposed MAGA Party as leverage to prevent Republican senators from voting to convict him during the Senate impeachment trial, and to field challengers to Republicans who voted for his impeachment in the House. The phrase was used again as the official slogan of Trump's 2024 presidential campaign. On June 3, 2023, Trump called his supporters Magadonians, prompting mockery on social media.

MAGA hat

During the 2016 campaign, Trump often used the slogan, especially by wearing MAGA hats emblazoned with the phrase in white letters, which soon became popular among his supporters. The slogan was so important to the campaign that at one point it spent more on making the hats – sold for $25 each on its website – than on polling, consultants, or television commercials. Millions were sold, and Trump estimated that counterfeit versions outnumbered the real hat ten to one. "... but it was a slogan, and every time somebody buys one, that's an advertisement." The hat's white-on-red design saw great success as a symbol of unity among Trump supporters.

Some critics have compared its use to other politically charged symbols, such as the Confederate flag, while supporters view it as an expression of patriotism and political identity. Due to its association with Trump and his policies, the hat has been a source of controversy. Some individuals view it as a divisive or provocative symbol, while others see it as an exercise of their political beliefs.

In January 2019, it gained media attention during a highly publicized standoff between a group of high schoolers wearing the hat and Omaha tribe leader Nathan Phillips. The incident was initially perceived by some as racially charged; however, subsequent video footage led to a reassessment of the situation by multiple media outlets. On December 29, 2022, the 9th Circuit Court of Appeals in Vancouver, Washington, ruled that wearing a MAGA hat is considered protected speech under the First Amendment.  A former teacher had worn a MAGA hat to class to school and described facing verbal harassment and retaliation from school employees.

Use on social media sites

Donald Trump took the campaign slogan to social media (primarily to Twitter), using the hashtags #makeamericagreatagain and its acronym #maga. In response to criticism regarding his frequent and untraditional usage of social media, Trump defended himself by tweeting "My use of social media is not Presidential – it's MODERN DAY PRESIDENTIAL. Make America Great Again!" on July 1, 2017.

In the first half of 2017, Trump posted his slogan on Twitter 33 times. In an article for Bloomberg News, Mark Whitehouse noted: "A regression analysis suggests the phrase adds (very roughly) 51,000 to a post's retweet-and-favorite count, which is important given that the average Trump tweet attracts a total of 107,000." Trump attributed his victory (in part) to social media when he said, "I won the 2016 election with interviews, speeches, and social media." According to RiteTag, the estimated hourly statistics for #maga on Twitter alone include: 1,304 unique tweets, 5,820,000 hashtag exposure, and 3,424 retweets with 14% of #maga tweets including images, 55% including links, and 51% including mentions.

Accusations of racism

Regarding its use since 2015, the phrase "Make America Great Again" is considered a loaded phrase and "dog whistle" by some. Marissa Melton, a Voice of America journalist, among others, argue it is a loaded phrase because it "doesn't just appeal to people who hear it as racist coded language, but also to those who have felt a loss of status as other groups have become more empowered." Sarah Churchwell argues the slogan now resonates as "America First" did in the early 1940s, with the idea "that the true version of America is the America that looks like me, the American fantasy I imagine existed before it was diluted with other races and other people."

Writing opinion for the Los Angeles Times, Robin Abcarian wrote that "[w]earing a 'Make America Great Again' hat is not necessarily an overt expression of racism. But if you wear one, it's a pretty good indication that you share, admire or appreciate President Trump's racist views about Mexicans, Muslims and border walls." The Detroit Free Press and the Los Angeles Times reported how several of their readers rejected this characterization and did not believe the slogan or MAGA hats are evidence of racism, seeing them more in patriotic or American nationalist terms. Los Angeles Times columnist Nicholas Goldberg described MAGA as both one of the worst campaign slogans ever and "a fabulous campaign slogan", writing: "It was vague enough to appeal to optimists generally, while leaving plenty of room for bitter and resentful voters to conclude that we were finally going back to the days when they ran the world." Actor Bryan Cranston said of the slogan: "So just ask yourself from, from an African American experience, when was it ever great in America for the African American? When was it great? If you're making it great again, it's not including them."

A 2018 study that used text mining and semantic network analytics of Twitter text and hashtags networks found that the "#MakeAmericaGreatAgain" and "#MAGA" hashtags were commonly used by white supremacist and white nationalist users, and had been used as "an organizing discursive space" for far-right extremists globally.

Derivative slogans

"Make America Great Again" has been the subject of many parodies, jokes, instances of praise, references, and criticisms which base themselves on the four-word slogan.

Derivatives used by Trump

"Keep America Great" has been the most popular derivative of "Make America Great Again", with Trump's 2020 presidential campaign adopting it as the official slogan, though often used alongside "Make America Great Again". Upon Trump announcing his candidacy for president in the 2024 election, commentators described his use of the tagline "Make America Great and Glorious Again" ("MAGAGA"). The term has come to be a humorous descriptor for Trump's re-election bid, and many outlets have commented on the humor that "MAGAGA" provides, usually on the word "gag" being part of the acronym.

At the 2024 Republican National Convention, some people wore clothing with the slogan "Make American Great Again Again". In October 2024, Trump promised former third-party candidate Robert F. Kennedy Jr. control of public health using the phrase "Make America Healthy Again". In November 2024, after Governor Gavin Newsom pledged to convene California lawmakers to secure California's progressive policies against the incoming Trump administration, Trump made "Make California Great Again" go viral on social media.

During a joint press conference with Philippine president Bongbong Marcos at the White House in July 2025, Trump voiced support for the Philippines' independent foreign policy and said, "I think he (Marcos) has to do what's right for his country. I've always said, you know, make the Philippines great again. Do whatever you need to do."

In January 2026, Trump said of Venezuelan vice president Delcy Rodríguez, "She's essentially willing to do what we think is necessary to make Venezuela great again." Rodríguez became acting president after the Trump administration captured Venezuelan president Nicolás Maduro and his wife and took them into custody in New York.

Make Iran Great Again

The slogan "Make Iran Great Again," coined by U.S. president Donald Trump, characterizes the Islamic regime as damaging Iran, and advocates for its replacement to help Iran become a stronger nation. This slogan was also used by the Iranian opposition group Restart.

Anti-Trump derivatives, parodies, and other derivatives

The phrase has been parodied in political statements, such as "Make America Mexico Again", a critique of Trump's immigration policies regarding the US–Mexico border and a reference to Mexico's loss of 55% of its territory to the US with the Treaty of Guadalupe Hidalgo.

Adult film star Stormy Daniels, who allegedly had an affair with President Trump, took part in a "Make America Horny Again" strip club tour. The tour followed Trump's initial 2016 campaign trail and part of the revenue was donated to Planned ParenthoodJohn Oliver spoofed the slogan on his show Last Week Tonight with John Oliver in a segment dedicated to Trump, urging viewers to "Make Donald Drumpf Again", in reference to the original ancestral name of the Trump family. The segment broke HBO viewership records, garnering 85 million views.

In 2017, after the certification of the election of Trump by Congress, then-Vice-president Joe Biden was heard saying "God Save the Queen", leading to History Today claiming it would get "Make America Great Britain Again". Later in the year, comedian Jimmy Kimmel repeated the phrase to suggest limiting presidential power. A 2018 essay about the Barack Obama birtherism conspiracy in the Journal of Hate Studies by two professors at Bates College was titled "Make America Hate Again: Donald Trump and the Birther Conspiracy".

A 2019 "Make Earth Greta Again" protestor in Berlin

The phrase has been adopted by some environmentalists. In June 2017, French president Emmanuel Macron rebuked Trump over withdrawing from the Paris Agreement. The last sentence of the speech he delivered was "make our planet great again". Members of the Fridays for Future Movement have also frequently used slogans like "Make Earth Greta Again", referring to environmental activist Greta Thunberg. In 2019, Grant Armour and Milene Larsson co-directed a documentary film named Make the World Greta Again. After Joe Biden defeated Trump in the 2020 presidential election, Biden's wife Jill posted an image of her and her husband on Instagram which featured Joe wearing a blue cap with white text reading "We Just Did", meant as a response to Trump's "Make America Great Again" slogan.

In late 2022, the political slogan "MAGA Communism" trended on Twitter after being tweeted out by former San Clemente city council candidate Jackson Hinkle. MAGA Communism adherents call on those who support the American working class to ally with members of the MAGA movement. During the presidential campaign Javier Milei in Argentina in 2023, the slogan MAGA was adapted as "Make Argentina Great Again". Milei, a personal friend, as well as an admirer of Trump, later won the election in November 2023, with Trump sending a congratulatory message with the slogan "Make Argentina Great Again". The term "Blue MAGA" is used to criticize a cult-like dedication to Biden as a person, the Democratic Party's use of conspiracy theories to explain opposition to Biden's 2024 presidential candidacy, and dismissals of information or polling that does not reflect well on Biden; the term seeks to suggest an equivalence between some supporters of Biden and Trump.

In early 2025, the Brazilian government's secretary of communication Sidônio Palmeira created the slogan "Brazil belongs to Brazilians" ("O Brasil é dos brasileiros")—printed on blue caps—at the request of then-on-leave secretary of institutional affairs Alexandre Padilha, with the aim of countering the "Make America Great Again" caps. Brazil's president Luiz Inácio Lula da Silva also posted a video on social media wearing the cap, in what has sometimes been referred to as the "battle of the caps" or "cap war". Padilha stated he was distressed to see people "saluting another country", in reference to former president Jair Bolsonaro; also following Trump's inauguration, the governor of São Paulo Tarcísio de Freitas appeared wearing a red cap with the phrase "Make America Great Again". In July of that year, after Trump's tariff hike against Brazil which was described by The Economist as the greatest interference since the Cold War, Lula da Silva adopted a nationalist stance, once again wearing a cap bearing the slogan "Brazil belongs to Brazilians". In August, during the second ministerial meeting of the year, Lula da Silva and his ministers wore the cap in question; the president and all 38 ministers posed for identification-style photographs on the occasion.

Use of the slogan by Trump's political rivals

After Donald Trump popularized the use of the phrase, the phrase and modifications of it were widely used in reference both to his election campaign and to his politics. Trump's primary opponents, Ted Cruz and Scott Walker, began using "Make America Great Again" in speeches, inciting Trump to send cease-and-desist letters to them. Cruz later sold hats featuring "Make Trump Debate Again" in response to Trump's boycotting the Iowa January 28, 2016, debate.

New York governor Andrew Cuomo said America "was never that great" during a September 2018 bill signing. Former United States attorney general Eric Holder questioned the slogan in a March 2019 interview on MSNBC, asking: "Exactly when did you think America was great?" During John McCain's memorial service on September 1, 2018, his daughter Meghan stated: "The America of John McCain has no need to be made great again because America was always great." Trump subsequently tweeted "MAKE AMERICA GREAT AGAIN!" later that day. Throughout Donald Trump's presidencies, the phrase "Is America great yet?" has been used both facetiously and as an actual poll question.

During remarks at the White House on May 4, 2022, President Joe Biden referred to former president Trump's Make America Great Again movement, saying, "This MAGA crowd is really the most extreme political organization that's existed in American history, in recent American history." On September 1, 2022, he dedicated remarks at the White House "on the continued battle for the soul of the nation", to attacks on "Donald Trump and the MAGA Republicans", saying that "Donald Trump and the MAGA Republicans represent an extremism that threatens the very foundations of our republic", and that "MAGA Republicans have made their choice. They embrace anger. They thrive on chaos. They live not in the light of truth but in the shadow of lies."

After Florida governor Ron DeSantis announced his run for the 2024 Republican Party presidential primary, several news outlets said he promised to "Make America Florida". One of the most widespread anti-Trump derivatives of "Make America Great Again" during the Trump presidency and the 2020 election was "Make America Think Again", often combined with 2020 Democratic primary candidate Andrew Yang's preferred version of "Make America Think Harder" ("MATH"). The slogan has been spotted at numerous anti-Trump events from Democratic political rallies to marches to social media, with Live Science noting "Think Again" as one of its top hashtags for 2017.

"Make America White Again"

Australian political commentator and former Liberal Party leader John Hewson used the satirical slogan "Make America White Again" in reference to his belief that recent global movements against traditional politics and politicians are based on racism and prejudice. He comments: "There should be little doubt about U.S. president Donald Trump's views on race, despite his occasional 'denials', assertions of 'fake news', and/or his semantic distinctions. His election campaign theme was effectively a promise to 'Make America Great Again; America First and Only' and—nod, nod, wink, wink—to Make America White Again." In a bid for attention, a few fringe racist political activists have associated "Make America Great Again" with a return to whiteness.

"Make America Great Again" has frequently been parodied in advertising, the media, and other outlets of popular culture, with varying levels of comparison to Trump from none at all to a rebuke of the former president and his ideology.

In advertising

The slogan was parodied by Dunk-a-roos as "Make America Dunk Again", and also in the film Sharknado 5: Global Swarming's tagline of "Make America Bait Again."

In artwork

Make Everything Great Again was a street art mural by artist Mindaugas Bonanu in Vilnius, Lithuania. Inspired by the graffiti painting My God, Help Me to Survive This Deadly Love, it depicts Donald Trump giving a fraternal kiss to the Russian president Vladimir Putin.

In fashion

Fashion designer Andre Soriano used the "Make America Great Again" official presidential campaign flag to design a MAGA gown for celebrities in Hollywood to wear on red carpet, such as at the 2017 Grammy Awards.

In films and web series

The tagline for the film The Purge: Election Year (2016) is "Keep America Great" (a phrase Trump would later use as his 2020 campaign slogan); one of the TV spots for the film featured Americans who explain why they support the Purge, with one stating he does so "to keep my country [America] great". The next film in the franchise, The First Purge, was subsequently advertised with a poster featuring its title stylized on a MAGA hat. In The Boys Season 4, the political slogan "Make America Super Again" serves as the main rallying cry for Homelander, the primary antagonist, as he successfully executes his own version of January 6 coup attempt in the universe of The Boys franchise.

In literature

Author Octavia E. Butler used "Make America Great Again" as the presidential campaign slogan for the dictator Andrew Steele Jarret in her 1998 dystopian novel Parable of the Talents. In 2011, Republican former United States Senate candidate Christine O'Donnell published a book about her campaign in the 2010 Delaware special election titled Troublemaker: Let's Do What It Takes to Make America Great Again. Political advisor Dan Pfeiffer's second book is called Un-Trumping America: A Plan to Make America a Democracy Again. Political commentator and author Peter Beinart published a 2006 book titled The Good Fight: Why Liberals – and Only Liberals – Can Win the War on Terror and Make America Great Again, drawing on the philosophy of theologian Reinhold Niebuhr after the 2003 invasion of Iraq and during the early years of the war on terror.

In music

Snoop Dogg's second EP is called Make America Crip Again with the second single titled "M.A.C.A." Dogg was quoted in Rolling Stone as saying that "Make America Great Again" refers to a time in the past that "always takes me back to separation and segregation so I'd rather Make America Crip Again" and referred to a time "when young black men in impoverished areas organized to help their communities and to take care of their own because society basically left them for dead". Singer Joy Villa produced a single "Make America Great Again" a few months after appearing at the 2017 Grammy Awards in a 'MAGA' dress. Australian heavy metal band Thy Art Is Murder recorded a song called "Make America Hate Again" on their album Human Target.

On television

(2015), supporters of Mr. Garrison, who runs a campaign that is a parody of Trump's, are seen holding signs bearing the slogan.

In video games

Senator Armstrong, the antagonist of the 2013 video game Metal Gear Rising: Revengeance uses the phrase "make America great again". Wolfenstein II: The New Colossus, a first-person shooter video game with Nazis as the enemy, was given the advertising tagline "Make America Nazi-Free Again", which some people objected to as anti-Trump, though a company executive said the game was not a "social critique on 2017 America." Peters Hines, the studio's vice president of marketing and public relations, was quoted on GamesIndustry.biz as saying, "Wolfenstein has been a decidedly anti-Nazi series since the first release more than 20 years ago. We aren't going to shy away from what the game is about. We don't feel it's a reach for us to say Nazis are bad and un-American, and we're not worried about being on the right side of history here."

Paradigm shift

From Wikipedia, the free encyclopedia

A paradigm shift is a fundamental change in the basic concepts and experimental practices of a scientific discipline. It is a concept in the philosophy of science that was introduced and brought into the common lexicon by the American physicist and philosopher Thomas Kuhn. Even though Kuhn restricted the use of the term to the natural sciences, the concept of a paradigm shift has also been used in numerous non-scientific contexts to describe a profound change in a fundamental model or perception of events.

Kuhn presented his notion of a paradigm shift in his influential book The Structure of Scientific Revolutions (1962).

Kuhn contrasts paradigm shifts, which characterize a Scientific Revolution, to the activity of normal science, which he describes as scientific work done within a prevailing framework or paradigm. Paradigm shifts arise when the dominant paradigm under which normal science operates is rendered incompatible with new phenomena, facilitating the adoption of a new theory or paradigm.

As one commentator summarizes:

Kuhn acknowledges having used the term "paradigm" in two different meanings. In the first one, "paradigm" designates what the members of a certain scientific community have in common, that is to say, the whole of techniques, patents and values shared by the members of the community. In the second sense, the paradigm is a single element of a whole, say for instance Newton's Principia, which, acting as a common model or an example... stands for the explicit rules and thus defines a coherent tradition of investigation. Thus the question is for Kuhn to investigate by means of the paradigm what makes possible the constitution of what he calls "normal science". That is to say, the science which can decide if a certain problem will be considered scientific or not. Normal science does not mean at all a science guided by a coherent system of rules, on the contrary, the rules can be derived from the paradigms, but the paradigms can guide the investigation also in the absence of rules. This is precisely the second meaning of the term "paradigm", which Kuhn considered the most new and profound, though it is in truth the oldest.

History

The nature of scientific revolutions has been studied by modern philosophy since Immanuel Kant used the phrase in the preface to the second edition of his Critique of Pure Reason (1787). Kant used the phrase "revolution of the way of thinking" (Revolution der Denkart) to refer to Greek mathematics and Newtonian physics. In the 20th century, new developments in the basic concepts of mathematics, physics, and biology revitalized interest in the question among scholars.

Original usage

Kuhn used the duck-rabbit ambiguous image, which Wittgenstein famously used to distinguish between the meaning of 'seeing as' and 'seeing that,' to show how a paradigm shift could cause one to see the same information in an entirely different way.

In his 1962 book The Structure of Scientific Revolutions, Kuhn explains the development of paradigm shifts in science into four stages:

  • Normal science – In this stage, which Kuhn sees as most prominent in science, a dominant paradigm is active. This paradigm is characterized by a set of theories and ideas that define what is possible and rational to do, giving scientists a clear set of tools to approach certain problems. Some examples of dominant paradigms that Kuhn gives are: Newtonian physics, caloric theory, and the theory of electromagnetism. Insofar as paradigms are useful, they expand both the scope and the tools with which scientists do research. Kuhn, in discussion of theory-ladenness, stresses that, rather than being monolithic, the paradigms that define normal science can be particular to different people. A chemist and a physicist might operate with different paradigms of what a helium atom is. Under normal science, scientists encounter anomalies that cannot be explained by the universally accepted paradigm within which scientific progress has thereto been made.
  • Extraordinary research – When enough significant anomalies have accrued against a current paradigm, the scientific discipline is thrown into a state of crisis. To address the crisis, scientists push the boundaries of normal science in what Kuhn calls “extraordinary research”, which is characterized by its exploratory nature. Without the structures of the dominant paradigm to depend on, scientists engaging in extraordinary research must produce new theories, thought experiments, and experiments to explain the anomalies. Kuhn sees the practice of this stage – “the proliferation of competing articulations, the willingness to try anything, the expression of explicit discontent, the recourse to philosophy and to debate over fundamentals” – as even more important to science than paradigm shifts.
  • Adoption of a new paradigm – Eventually a new paradigm is formed, which gains its own new followers. For Kuhn, this stage entails both resistance to the new paradigm, and reasons for why individual scientists adopt it. According to Max Planck, "a new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it." Because scientists are committed to the dominant paradigm, and paradigm shifts involve gestalt-like changes, Kuhn stresses that paradigms are difficult to change. However, paradigms can gain influence by explaining or predicting phenomena much better than before (i.e., Bohr's model of the atom) or by being more subjectively pleasing. During this phase, proponents for competing paradigms address what Kuhn considers the core of a paradigm debate: whether a given paradigm will be a good guide for future problems – things that neither the proposed paradigm nor the dominant paradigm are capable of solving currently.
  • Aftermath of the scientific revolution – In the long run, the new paradigm becomes institutionalized as the dominant one. Textbooks are written, obscuring the revolutionary process.

A common misinterpretation of paradigms is the belief that the discovery of paradigm shifts and the dynamic nature of science (with its many opportunities for subjective judgments by scientists) are a case for relativism: the view that all kinds of belief systems are equal. Kuhn vehemently denies this interpretation and states that when a scientific paradigm is replaced by a new one, albeit through a complex social process, the new one is always better, not just different.

Incommensurability

These claims of relativism are, however, tied to another claim that Kuhn does at least somewhat endorse: that the language and theories of different paradigms cannot be translated into one another or rationally evaluated against one another—that they are incommensurable. This gave rise to much talk of different peoples and cultures having radically different worldviews or conceptual schemes—so different that whether or not one was better, they could not be understood by one another.

Donald Davidson famously argued against this idea of conceptual relativism, claiming that the notion that any languages or theories could be incommensurable with one another was itself incoherent. If this is correct, Kuhn's claims must be taken in a weaker sense than they often are.

Furthermore, the hold of the Kuhnian analysis on social science has long been tenuous, with the wide application of multi-paradigmatic approaches in order to understand complex human behaviour.

Gradualism vs. sudden change

Paradigm shifts tend to be most dramatic in sciences that appear to be stable and mature, as in physics at the end of the 19th century. At that time, physics seemed to be a discipline filling in the last few details of a largely worked-out system.

In The Structure of Scientific Revolutions, Kuhn wrote, "Successive transition from one paradigm to another via revolution is the usual developmental pattern of mature science" (p. 12). Kuhn's idea was itself revolutionary in its time as it caused a major change in the way that academics talk about science. Thus, it could be argued that it caused or was itself part of a "paradigm shift" in the history and sociology of science. However, Kuhn would not recognise such a paradigm shift. In the social sciences, people can still use earlier ideas to discuss the history of science.

Philosophers and historians of science, including Kuhn himself, ultimately accepted a modified version of Kuhn's model, which synthesizes his original view with the gradualist model that preceded it.

Examples

Natural sciences

Some of the "classical cases" of Kuhnian paradigm shifts in science are:

Social sciences

In Kuhn's view, the existence of a single reigning paradigm is characteristic of the natural sciences, while philosophy and much of social science were characterized by a "tradition of claims, counterclaims, and debates over fundamentals." Others have applied Kuhn's concept of paradigm shift to the social sciences.

Applied sciences

More recently, paradigm shifts are also recognisable in applied sciences:

Other uses

The term "paradigm shift" has found uses in other contexts, representing the notion of a major change in a certain thought pattern—a radical change in personal beliefs, complex systems or organizations, replacing the former way of thinking or organizing with a radically different way of thinking or organizing:

  • M. L. Handa, a professor of sociology in education at O.I.S.E. University of Toronto, Canada, developed the concept of a paradigm within the context of social sciences. He defines what he means by "paradigm" and introduces the idea of a "social paradigm". In addition, he identifies the basic component of any social paradigm. Like Kuhn, he addresses the issue of changing paradigms, the process popularly known as "paradigm shift". In this respect, he focuses on the social circumstances that precipitate such a shift. Relatedly, he addresses how that shift affects social institutions, including the institution of education.
  • The concept has been developed for technology and economics in the identification of new techno-economic paradigms as changes in technological systems that have a major influence on the behaviour of the entire economy (Carlota Perez; earlier work only on technological paradigms by Giovanni Dosi). This concept is linked to Joseph Schumpeter's idea of creative destruction. Examples include the move to mass production and the introduction of microelectronics.
  • Two photographs of the Earth from space, "Earthrise" (1968) and "The Blue Marble" (1972), are thought to have helped to usher in the environmentalist movement, which gained great prominence in the years immediately following distribution of those images.
  • Hans Küng applies Thomas Kuhn's theory of paradigm change to the entire history of Christian thought and theology. He identifies six historical "macromodels": 1) the apocalyptic paradigm of primitive Christianity, 2) the Hellenistic paradigm of the patristic period, 3) the medieval Roman Catholic paradigm, 4) the Protestant (Reformation) paradigm, 5) the modern Enlightenment paradigm, and 6) the emerging ecumenical paradigm. He also discusses five analogies between natural science and theology in relation to paradigm shifts. Küng addresses paradigm change in his books, Paradigm Change in Theology and Theology for the Third Millennium: An Ecumenical View.
  • In the later part of the 1990s, 'paradigm shift' emerged as a buzzword, popularized as marketing speak and appearing more frequently in print and publication. In his book Mind The Gaffe, author Larry Trask advises readers to refrain from using it, and to use caution when reading anything that contains the phrase. It is referred to in several articles and books as abused and overused to the point of becoming meaningless.
  • The concept of technological paradigms has been advanced, particularly by Giovanni Dosi.

Criticism

In a 2015 retrospective on Kuhn, the philosopher Martin Cohen describes the notion of the paradigm shift as a kind of intellectual virus – spreading from hard science to social science and on to the arts and even everyday political rhetoric today. Cohen claims that Kuhn had only a very hazy idea of what it might mean and, in line with the Austrian philosopher of science Paul Feyerabend, accuses Kuhn of retreating from the more radical implications of his theory, which are that scientific facts are never really more than opinions whose popularity is transitory and far from conclusive. Cohen says scientific knowledge is less certain than it is usually portrayed, and that science and knowledge generally is not the 'very sensible and reassuringly solid sort of affair' that Kuhn describes, in which progress involves periodic paradigm shifts in which much of the old certainties are abandoned in order to open up new approaches to understanding that scientists would never have considered valid before. He argues that information cascades can distort rational, scientific debate. He has focused on health issues, including the example of highly mediatised 'pandemic' alarms, and why they have turned out eventually to be little more than scares.

One of the early critics of Kuhn, Norwood Russell Hanson criticized Kuhn's paradigm shift theory as being conceptually circular and therefore unfalsifiable.

There is a discussion about genetic fallacy in the concept of paradigm shift and the way in which theories are evaluated.
