When you ask ChatGPT or other AI assistants to help create misinformation, they typically refuse, with responses like “I cannot assist with creating false information.” But our tests show these safety measures are surprisingly shallow – often just a few words deep – making them alarmingly easy to circumvent.

We have been investigating how AI language models can be manipulated to generate coordinated disinformation campaigns across social media platforms. What we found should concern anyone worried about the integrity of online information.

The shallow safety problem

We were inspired by a recent study from researchers at Princeton and Google. They showed current AI safety measures primarily work by controlling just the first few words of a response. If a model starts with “I cannot” or “I apologise”, it typically continues refusing throughout its answer.

Our experiments – not yet published in a peer-reviewed journal – confirmed this vulnerability. When we directly asked a commercial language model to create disinformation about Australian political parties, it correctly refused.

However, we also tried the exact same request as a “simulation” where the AI was told it was a “helpful social media marketer” developing “general strategy and best practices”. In this case, it enthusiastically complied.

The AI produced a comprehensive disinformation campaign falsely portraying Labor’s superannuation policies as a “quasi inheritance tax”. It came complete with platform-specific posts, hashtag strategies, and visual content suggestions designed to manipulate public opinion.

The main problem is that the model can generate harmful content but isn’t truly aware of what is harmful, or why it should refuse. Large language models are simply trained to start responses with “I cannot” when certain topics are requested.

Think of a security guard checking minimal identification when allowing customers into a nightclub. If they don’t understand who and why someone is not allowed inside, then a simple disguise would be enough to let anyone get in.

Real-world implications

To demonstrate this vulnerability, we tested several popular AI models with prompts designed to generate disinformation.

The results were troubling: models that steadfastly refused direct requests for harmful content readily complied when the request was wrapped in seemingly innocent framing scenarios. This practice is called “model jailbreaking”.

The ease with which these safety measures can be bypassed has serious implications. Bad actors could use these techniques to generate large-scale disinformation campaigns at minimal cost. They could create platform-specific content that appears authentic to users, overwhelm fact-checkers with sheer volume, and target specific communities with tailored false narratives.

The process can largely be automated. What once required significant human resources and coordination could now be accomplished by a single individual with basic prompting skills.

The technical details

The American study found AI safety alignment typically affects only the first 3–7 words of a response. (Technically this is 5–10 tokens – the chunks AI models break text into for processing.)

This “shallow safety alignment” occurs because training data rarely includes examples of models refusing after starting to comply. It is easier to control these initial tokens than to maintain safety throughout entire responses.

Moving toward deeper safety

The US researchers propose several solutions, including training models with “safety recovery examples”. These would teach models to stop and refuse even after beginning to produce harmful content.

They also suggest constraining how much the AI can deviate from safe responses during fine-tuning for specific tasks. However, these are just first steps.

As AI systems become more powerful, we will need robust, multi-layered safety measures operating throughout response generation. Regular testing for new techniques to bypass safety measures is essential.

Also essential is transparency from AI companies about safety weaknesses. We also need public awareness that current safety measures are far from foolproof.

AI developers are actively working on solutions such as constitutional AI training. This process aims to instil models with deeper principles about harm, rather than just surface-level refusal patterns.

However, implementing these fixes requires significant computational resources and model retraining. Any comprehensive solutions will take time to deploy across the AI ecosystem.

The bigger picture

The shallow nature of current AI safeguards isn’t just a technical curiosity. It’s a vulnerability that could reshape how misinformation spreads online.

AI tools are spreading through into our information ecosystem, from news generation to social media content creation. We must ensure their safety measures are more than just skin deep.

The growing body of research on this issue also highlights a broader challenge in AI development. There is a big gap between what models appear to be capable of and what they actually understand.

While these systems can produce remarkably human-like text, they lack contextual understanding and moral reasoning. These would allow them to consistently identify and refuse harmful requests regardless of how they’re phrased.

For now, users and organisations deploying AI systems should be aware that simple prompt engineering can potentially bypass many current safety measures. This knowledge should inform policies around AI use and underscore the need for human oversight in sensitive applications.

As the technology continues to evolve, the race between safety measures and methods to circumvent them will accelerate. Robust, deep safety measures are important not just for technicians – but for all of society.

In recent years, Pacific island nations have earned global credibility as champions of climate action. Pacific leaders view sea level rise as an existential threat.

But this united front is now under strain as some Pacific nations pursue a controversial new industry – deep-sea mining. Nauru, the Cook Islands, Kiribati and Tonga have gone the furthest to make it a reality, attracted by new income streams. But nations such as Fiji, Palau and Vanuatu have called for a moratorium on deep-sea mining in international waters.

Public opinion across the Pacific is often divided, pitting possible economic gains against the potential risks of an industry whose environmental impact remain uncertain but potentially significant. As this tension intensifies, it may split the Pacific and risk the region’s moral authority on climate.

What are the concerns over deep-sea mining?

Deep-sea mining targets three types of mineral deposits – polymetallic nodules strewn across deep underwater plains, cobalt-rich crusts on seamounts, and the ore deposits around hydrothermal vents.

To extract them, mining companies can use unmanned collectors to pump ore to the surface and return the wastewater. This creates plumes of sediment which can smother marine life. Methods of minimising damage to species from mining on land are largely unworkable at depth.

Deep-sea ecosystems are poorly understood, but we know they are slow to recover. Researchers have found areas mined as a test more than 40 years ago still show physical damage and immobile corals and sponges remain scarce.

Why is there so much interest in deep-sea mining?

Deep-sea mining hasn’t begun anywhere in earnest, because the International Seabed Authority has yet to finalise rules governing extraction. This authority oversees the 54% of the world’s oceans beyond territorial waters.

But plans for deep-sea mining operations can still be submitted and considered without these rules in place.

Analysts have estimated seabed minerals could be worth a staggering A$30 trillion. Some of the richest deposits lie in the Clarion-Clipperton Zone in international waters between Hawaii and Mexico, thousands of kilometres away from Pacific nations. Under international law, companies cannot mine in international waters on their own. They need to be officially sponsored by a national government, which has to keep effective control over its operations.

One reason deep-sea mining companies see Pacific states as such useful partners is that these countries can access
reserved areas of international seabed set aside for developing countries, as well as potential resources in the very large territorial waters around many island states.

Backers in Nauru, Tonga, the Cook Islands and Kiribati argue rising demand for manganese, cobalt, copper and nickel could deliver significant economic returns and diversify economies.

Nauru

Nauru’s enormous deposits of guano – compressed seabird excrement long sought as fertiliser – once made the country wealthy. But the guano is largely gone and the small nation has limited other resources.

Nauru sponsors Nauru Ocean Resources, a wholly owned subsidiary of seabed mining company The Metals Company. In 2011, the company received an International Seabed Authority contract permitting exploration of polymetallic nodules in the Clarion-Clipperton Zone, more than 8,000km from Nauru.

Nauru has since “proudly taken a leading role” in developing international legal frameworks in mining nodules in the international seabed.

In June, Nauru signalled Nauru Ocean Resources would apply for an exploitation license.

Tonga

Tonga’s government is similarly backing deep-sea mining by partnering with The Metals Company to explore mining in the Clarion-Clipperton Zone.

In August 2025, Tonga signed an updated agreement with Tonga Offshore Mining, a subsidiary of The Metals Company. The agreement was originally signed in 2021 amid large-scale criticism over the lack of public consultation.

The mining company has promised new benefits, ranging from financial benefits, scholarships and community programs. Even so, the revised deal has encountered opposition from civil society, young people and legal experts. Prominent Tongans remain unconvinced, citing environmental, legal and transparency risks.

Economic pressure is part of the picture. Tonga owes an estimated A$180 million to China’s Exim Bank – roughly a quarter of its annual GDP.

Cook Islands

The 15 Cook Islands are widely scattered, giving the government exclusive rights to almost two million square kilometres of ocean. The government has issued exploration licences inside its Exclusive Economic Zone to three companies – Cook Islands Consortium, CIIC Seabed Resources Limited, and Moana Minerals. The Cook Islands government has established a domestic regulatory framework and is building research capacity.

Kiribati

Kiribati’s atolls and island are even more dispersed. The nation’s exclusive economic zone covers about 3.4 million km². The state-owned Marawa Research and Exploration company holds a 15-year exploration contract with the seabed authority. Kiribati has opened talks with China to explore potential collaboration.

The Pacific split

While revenues could potentially be sizeable for the Pacific, costs, technologies and environmental liabilities are highly uncertain.

The experience of Papua New Guinea is a cautionary tale. In 2019, the PNG deep-sea mining venture Solwara-1 went into administration following intense community pushback. The fallout cost the government an estimated $184 million. The PNG government now opposes deep-sea mining in its territorial waters.

While deep-sea mining now has clear backers, other nations are far more wary.

In 2022, Palau launched an alliance calling for a moratorium on mining in international waters. Early signatories included Fiji, American Samoa and the Federated States of Micronesia. Since then, Tuvalu, Vanuatu and the Marshall Islands have joined, as well as dozens of other countries. PNG has not yet joined.

Opposition from these Pacific states is based on the precautionary principle, which favours caution when knowledge is limited and damage is possible.

Pacific youth are among the most prominent opponents of deep-sea mining. The regional Pacific Blue Line coalition uniting civil society, faith groups, women’s organisations and youth networks has consistently called for a complete ban in the region. Young people have spoke out publicly in nations such as Tonga, where youth advocates criticised limited consultation and rallied against the plans, as well as the Cook Islands, where young people have demanded transparency.

Reputation under a cloud?

Pacific leaders have built a worldwide reputation for their principled climate diplomacy, from championing the 1.5°C goal to the major new advisory opinion on climate change issued by the world’s top court in response to a case instigated by students from the University of the South Pacific.

If some Pacific leaders open the door fully to deep-sea mining, it risks undermining the region’s united front on environmental issues and threatens its credibility.

The way this plays out will shape how the world hears the Pacific on climate and the oceans in the years ahead.

Some say the law / ought not to bend. // That it should be a neutral, / certain thing. // But there are reasons / judgement and interpretation / are bequeathed / to human / – humane – / hearts, and heads.

– Excerpt from The Hope of a Thousand Small Lights, Maxine Beneba Clarke

On January 23 2025, the International Criminal Court’s (ICC) chief prosecutor applied for arrest warrants for the Taliban’s supreme leader and Afghanistan’s chief justice, charging them with the persecution of women, a crime against humanity. It was a long overdue decision.

These arrest warrants, said Amnesty International, gave

hope, inside and outside the country to Afghan women, girls, as well as those persecuted on the basis of gender identity or expression.

And hope in justice is important.

The ICC is a Hague-based court with the power to prosecute war crimes, crimes against humanity and genocide. Today, it explicitly recognises sexual slavery, enforced prostitution, forced pregnancy, enforced sterilisation and gender-based persecution as distinct crimes.

But the recognition of gender-based abuses as distinct crimes under international law is relatively recent. The ICC has been widely criticised for its slow and lengthy processes, with an abysmal rate of convictions.

Review: Feminist Judgments: Reimagining the International Criminal Court – edited by Kcasey McLoughlin, Rosemary Grey, Louise Chappell & Suzanne Varrall (Cambridge University Press)

---

In its 23-year history of operation, only 11 ICC cases have resulted in convictions. Just two of those, relating to crimes in Congo and Uganda, included successful convictions for sexual and gender-based crimes.

What would it take for more of these cases to result in successful prosecutions of gender-based crimes? What would be required to bring “gender-sensitive judging” into practice? And might it be possible to imagine a world where laws are written with a specific focus on benefiting women and people of diverse genders?

These are some of the questions the feminist judgment “movement” seeks to answer. In this movement, scholars and practitioners rewrite judgments in decided cases from a feminist perspective.

A new book, Feminist Judgments: Reimagining the International Criminal Court, brings together nearly 50 authors, of all genders, from the Global North and Global South. In this collection, edited by Australian legal scholars Kcasey McLoughlin, Rosemary Grey, Louise Chappell and Suzanne Varrall, academics, advocates, and legal practitioners “re-envision a range of judgements” delivered at the ICC.

Similar projects conducted around the world have rewritten feminist judgments from courts in the United Kingdom, Ireland, Scotland, New Zealand, Canada, United States, Australia and India. But this is the first book to examine decisions made by ICC judges; decisions that carry “far-reaching consequences”.

The ICC holds prosecutorial authority in over 120 countries. The court’s rulings also, as the editors write, serve “as persuasive precedents in other international, regional, and national criminal courts”.

Alternative judgments

Contributors address nine ICC situations in Afghanistan, Myanmar/Bangladesh, the Central African Republic, the Democratic Republic of Congo, Cote d’Ivoire, Mali, Sudan and Uganda. Because ICC cases are so large, each rewritten decision focuses on a single issue of law, fact or procedure addressed in the original decision.

For example, Suzanne Varrall and Sarah Williams rewrite the acquittal of former Congolese vice president and militia leader Jean Pierre Bemba Gombo by the ICC Appeals Chamber. Bemba’s was the ICC’s first case to include charges and a conviction for sexual violence. It was overturned on appeal in 2018.

The authors argue the court should factor in sexual and gender-based violence when interpreting and applying the doctrine of command responsibility, or a commander’s responsibility to prevent violations of international humanitarian law by their troops.

Most sexual and gender-based violence in conflict affects women and girls. But in applying a gender-sensitive approach, Varrall and Williams remind us, judges would also challenge traditional views of gender roles such as the idea that all men are combatants. Civilian men and boys can also be victims.

Currently, 50% of judges at the ICC are women but having women judges does not automatically mean they hold feminist perspectives, or possess a specific gender expertise. The ICC Prosecutor’s Office has published a comprehensive gender policy and appointed gender advisors as a part of a commitment to support gender justice and improve its track record in prosecuting gender-based crimes.

One of the major themes emerging from this collection is the need for judges to make decisions informed by the lived experiences of those affected by international crimes. Survivors’ experiences are not only to be heard, but listened to “with particular care”, as eminent international jurist Navi Pillay reminds us in her foreword.

Pillay, a former judge of the International Criminal Tribunal for Rwanda and the ICC, was the judge in the 1998 Akayesu case, the world’s first case confirming sexual violence can be an act of genocide.

The case brought against a former village mayor in Rwanda, Jean-Paul Akayesu, achieved some justice for an estimated 250,000-500,000 women and girls raped in the 1994 Rwandan genocide. While listening to the testimony of witness “JJ” in the case, Pillay became convinced that the traditional “body penetration” definition of rape was not appropriate in the context of mass rapes during war.

In such contexts, rape is never “just penetration” of the body itself. It becomes a calculated act of cruelty, a combination of humiliation, degradation, public nudity and the unbearable pain of having one’s children witness the abuse of their mother. Rape in the context of mass atrocity morphs into a destruction of the spirit and of the will to live, leaving a lifelong scar.

Feminist judgments can have an impact. A minority opinion, for instance, may one day become the prevailing orthodoxy.
Feminist judgments are an exercise in consciousness-raising, primarily designed to educate and transform legal discourse.

This collection goes beyond traditional legal analysis by incorporating photography and poetry, including Beneba Clarke’s The Hope of a Thousand Small Lights. It recognises justice can have many different meanings; that it can be symbolic too, and still profoundly meaningful to victims.

Political constraints

Rewritten judgments in this collection offer clear guidance for ICC courts on how to advance gender-sensitive jurisprudence in cases of atrocity. But the ICC faces political constraints, including attacks on its authority from the Trump administration.

In November 2024, the court issued warrants of arrest for the now deceased Hamas leader, Mohammed Diab Ibrahim Al-Masri, allegedly responsible for the October 2023 attacks in Israel. These charges, withdrawn after his death, included sexual violence crimes committed in Israel on October 7.

The court also charged Israeli Prime Minister Benjamin Netanyahu, and former Defence Minister Yoav Gallant in relation to war crimes in Gaza, including starvation and targeting civilians, and crimes against humanity.

This month, the US State Department announced new sanctions on four ICC officials, including two judges and two prosecutors, claiming they were instrumental in efforts to prosecute Americans and Israelis. The US is not a member of the ICC. The court has denounced these sanctions as a “flagrant attack against the independence of an impartial judicial institution”.

If the ICC is perceived as lacking impartiality, this will limit its ability to address the gendered and intersectional dimensions of atrocity worldwide.

War and gender

War exacerbates previously existing gender inequalities. Around 110 instances of armed conflict are underway around the world; Africa and the Middle East are the most affected regions.

Many of these conflicts are intractable, dragging on for decades. With technology in warfare rapidly evolving, the growing application of AI and machine learning in weapons has gendered impacts. Attacks by explosive weapons in residential areas, for instance, disproportionately affect women and girls, since they often have primary responsibility for buying household goods or food at markets. Wars are also becoming less likely to be resolved politically.

The collective behind Feminist Judgments: Reimagining the International Criminal Court acknowledge that, even with its best efforts, the ICC can only achieve a limited and selective accountability. They encourage victims to pursue justice in other ways, not necessarily retributive. Perhaps those ways could be restorative or symbolic. Initiatives in arts, storytelling and memorialisation can bring some closure to survivors, while strengthening the social fabric of the nation.

With no meaningful recourse for women to Afghan courts and only limited access to courts of other states, the ICC remains the only viable judicial venue in which to prosecute the Taliban leaders for gender persecution.

However, the chances of seeing these leaders appear before the ICC are slim. They depend on arresting the defendants, who have publicly denounced the ICC warrants for their arrest. And the ICC has never conducted a trial in absentia. The court’s governing framework, known as the Rome Statute, states: “the accused shall be present during the trial”.

Almost 50% of individuals accused by the ICC are not brought to justice.

The court hopes charges confirmed in their absence could perhaps bring some redress to victims. Despite the absence of the accused, victims would still have an opportunity to finally speak out before a court – and the evidence would be examined, presented and documented for future reference.

The annual clock of the seasons – winter, spring, summer, autumn – is often taken as a given. But our new study in Nature, using a new approach for observing seasonal growth cycles from satellites, shows that this notion is far too simple.

We present an unprecedented and intimate portrait of the seasonal cycles of Earth’s land-based ecosystems. This reveals “hotspots” of seasonal asynchrony around the world – regions where the timing of seasonal cycles can be out of sync between nearby locations.

We then show these differences in timing can have surprising ecological, evolutionary, and even economic consequences.

Watching the seasons from space

The seasons set the rhythm of life. Living things, including humans, adjust the timing of their annual activities to exploit resources and conditions that fluctuate through the year.

The study of this timing, known as “phenology”, is an age-old form of human observation of nature. But today, we can also watch phenology from space.

With decades-long archives of satellite imagery, we can use computing to better understand seasonal cycles of plant growth. However, methods for doing this are often based on the assumption of simple seasonal cycles and distinct growing seasons.

This works well in much of Europe, North America and other high-latitude places with strong winters. However, this method can struggle in the tropics and in arid regions. Here, satellite-based estimates of plant growth can vary subtly throughout the year, without clear-cut growing seasons.

Surprising patterns

By applying a new analysis to 20 years of satellite imagery, we made a better map of the timing of plant growth cycles around the globe. Alongside expected patterns, such as delayed spring at higher latitudes and altitudes, we saw more surprising ones too.

One surprising pattern happens across Earth’s five Mediterranean climate regions, where winters are mild and wet and summers are hot and dry. These include California, Chile, South Africa, southern Australia, and the Mediterranean itself.

These regions all share a “double peak” seasonal pattern, previously documented in California, because forest growth cycles tend to peak roughly two months later than other ecosystems. They also show stark differences in the timing of plant growth from their neighbouring drylands, where summer precipitation is more common.

Spotting hotspots

This complex mix of seasonal activity patterns explains one major finding of our work: the Mediterranean climates and their neighbouring drylands are hotspots of out-of-sync seasonal activity. In other words, they are regions where the seasonal cycles of nearby places can have dramatically different timing.

Consider, for example, the marked difference between Phoenix, Arizona (which has similar amounts of winter and summer rainfall) and Tucson only 160 km away (where most rainfall comes from the summer monsoon).

Other global hotspots occur mostly in tropical mountains. The intricate patterns of out-of-sync seasons we observe there may relate to the complex ways in which mountains can influence airflow, dictating local patterns of seasonal rainfall and cloud. These phenomena are still poorly understood, but may be fundamental to the distribution of species in these regions of exceptional biodiversity.

Seasonality and biodiversity

Identifying global regions where seasonal patterns are out of sync was the original motivation for our work. And our finding that they overlap with many of Earth’s biodiversity hotspots – places with large numbers of plant and animal species – may not be a coincidence.

In these regions, because seasonal cycles of plant growth can be out of sync between nearby places, the seasonal availability of resources may be out of sync, too. This would affect the seasonal reproductive cycles of many species, and the ecological and evolutionary consequences could be profound.

One such consequence is that populations with out-of-sync reproductive cycles would be less likely to interbreed. As a result, these populations would be expected to diverge genetically, and perhaps eventually even split into different species.

If this happened to even a small percentage of species at any given time, then over the long haul these regions would produce large amounts of biodiversity.

Back down to Earth

We don’t yet know whether this has really been happening. But our work takes the first steps towards finding out.

We show that, for a wide range of plant and animal species, our satellite-based map predicts stark on-ground differences in the timing of plant flowering and in genetic relatedness between nearby populations.

Our map even predicts the complex geography of coffee harvests in Colombia. Here, coffee farms separated by a day’s drive over the mountains can have reproductive cycles as out of sync as if they were a hemisphere apart.

Understanding seasonal patterns in space and time isn’t just important for evolutionary biology. It is also fundamental to understanding the ecology of animal movement, the consequences of climate change for species and ecosystems, and even the geography of agriculture and other forms of human activity.

“I’ve had Japanese people crying when I tell them I’m not Diana,” British woman Christina Hance, who sometimes earned thousands of pounds a day as a Diana impersonator, told the BBC in 1996. A few months later, she announced she was stepping back from her duties as a Diana lookalike, saying the job had sent her mad and made her ill.

“I ended up a zombie just like her […] the strain of public life has been too much for both of us,” she said. Probably the best known of countless professional Diana impersonators, she “didn’t really look very much like Diana at all”, according to Edward White, whose new book Dianaworld: An Obsession is at least as much about “the princess’s people” as the “People’s Princess”.

In other words, it’s about “the sprawling, ever-evolving precinct of her various lives – public and private, real and imagined” – while mapping how Diana-the-icon has been created by her various “publics”.

---

Review: Dianaworld: An Obssession – Edward White (Allen Lane)

---

These “publics” sprang from diverse communities: from couturiers to courtiers, hairdressers to politicians, royal servants to sex workers, astrologers to gays, newspapermen to fickle paternal advisors – and soothsayers, superfans and satirists. And, of course, lookalikes.

Dianaworld describes a Diana who was many things to many people. “Dig deep enough”, White suggests, and you’ll find a part of Diana that was Jewish, or American, or a republican – or anything else that she wasn’t but you are.“

First and foremost, though, she was the “pale English rose celebrated for strengthening the Windsor monarchy with the DNA of her indigenous British ancestors”. She was “unencumbered by class identity, snobbery, or elitism of any kind precisely because she was so thoroughly, truly, aristocratic”.

Tony Blair once told an interviewer Diana invented a “new way to be British”. White proposes: “It might be more accurate to say that through Diana, the British invented a new way of fantasizing about themselves.” And:

Never was the domestic adulation of Diana so complete as when she was on the other side of the world. Organs of the British media documented her popularity abroad with an embarrassing neediness.

White charts how the cult of Diana assumed global proportions.

The United States liked to claim Diana as “an American princess” – for “only in America did Diana fully become Diana”, writes White. He argues she personified “the American Dream”, springing as she did from the life of a relative mortal (if one whose “family had been a mighty social presence for half a millennium”) to the superstardom of global celebrity.

Diana often expressed a desire to relocate to the US, thousands of miles away from the strictures of the House of Windsor and arc-lamp intensity of the British tabloid press.

Sound familiar? It seems Prince Harry’s destiny was written for him by his mother.

When visiting Pakistan, India and various African and Middle Eastern countries, Diana was seen as a “post-imperial princess whose image transcended all kinds of social barriers, real and imagined”.

White documents a group of Pakistani women who thrilled to the idea of Diana’s potential marriage to British-Pakistani cardiac surgeon Hasnat Khan, because it showed Diana “was doing what every Asian daughter was meant to do: marrying an Asian doctor”.

Ahead of the Charles and Diana 1986 tour of Japan, thousands of Japanese schoolchildren were gifted Diana robot dolls. Numerous Diana lookalikes and impersonators donned Diana wigs and made appearances at supermarkets.

Across several chapters, White returns to the idea of Diana’s “relationship with Britishness, especially the English component of that identity”. Back in Britain, Diana enjoyed a large following among the nation’s ethnic minority, as well as with the gay community. Her association with the latter was forged by her early embrace of the cause of HIV/AIDS. White writes: “the memory of her has become entwined with a particular idea of gay experience, in which defiance and radical honesty are king and queen.

Acknowledging how Diana was “a woman of mythological complexity and far-reaching significance”, White dissects how so much of the mythologising tends to heap “cliché and trope upon her mythological pyre”.

As the “fairytale princess at the centre of an archetypal romantic fantasy”, Diana was “loaded with other people’s ideas about love for close to half a century”. Dianaworld charts how this “love” spilled over to obsession, in alarming ways.

Sexual obsession

Dianaworld touches on the public’s sexual obsession with the princess, filtered through the male gaze of the media and the royal establishment.

One of the most interesting groups of Diana supporters White identifies are the older, well-connected paternalistic admirers who assumed the mantle of “fatherly advisor”. The likes of Clive James, film producer David Puttnam, and actor and director Richard Attenborough offered her advice on how to perform her royal role and navigate her life post-separation.

One, former British MP Woodrow Wyatt, wrote approvingly in his diary of Diana’s innocent feminine allure, but changed his view after revelations of her extra marital affairs were made in Andrew Morton’s Diana: Her True Story, casting her in a madonna-whore paradigm.

No longer required to revere Diana as the English rose, Wyatt – and many others like him – was now free to despise her and desire her, the nasty twin impulses that had always hovered in the backdrop of the soft-focus princess worship of earlier, more innocent, less honest times.

Lavish and inconstant, tyrannical and needy

Dianaland charts how the cult of “Diana love/obsession” had its parallel in the way Diana conducted her own private relationships.

It seems that she loved others in private in the way that her public loved her – lavishly and inconstantly, stiflingly and adoringly, tyrannically and needily, all or nothing.

With Prince Charles, she passed as an outdoors-loving fan of stalking deer, shooting grouse, fly-fishing and long country hikes. With James Hewitt, she took up riding lessons and clothed her young sons in junior-sized military uniforms. With rugby union player Will Carling, she became a football fan (Carling has denied they had an affair). And with cardiac surgeon Hasnat Kahn, she donned a surgical robe and mask and was filmed watching him perform heart surgery.

When the police interviewed Diana after hundreds of silent phone calls made to art dealer Oliver Hoare’s home were traced to Kensington Palace, another image of Diana emerged: both stalked and stalker.

Influences

Dianaworld is a compendium of existing scholarship about the princess, taking its lead from Michael Billig’s groundbreaking sociological study from the early 1980s, Talking of the Royal Family, and Jude Davies’ 2001 Diana, A Cultural History: Gender, Race, Nation and the People’s Princess

It draws heavily, too, on the biographies of Diana by Sally Bedell Smith (1999), Sarah Bradford (2006) and Tina Brown (2007).

Nonetheless, it distinguishes itself by choosing to take an often amusing, lighthearted approach, more in line with Diana Simmonds’ Squidgie Dearest (1995) and Craig Brown’s Princess Margaret biography, Ma’am Darling (2017).

In this way, it recognises how the worlds of the princess’ people are often absurd and nonsensical, fantastical and comical.

So many Dianas

White describes, for example, one British cinema preview audience’s laughter at the inadvertently hilarious dialogue of one of the early Diana and Charles biopics.

Diana: “I just need you to hold me and touch me”; Charles: “Yes, but you’re always being sick.”

He employs some wry wit to recount how Diana was given an award for Humanitarian of the Year “at a glitzy ceremony in New York at the end of 1995, among a who’s who of selfless lovers of humanity, including Henry Kissinger and Donald Trump”.

One chapter, Dianarama, about the memorialisation of Diana in public art, tells the story of the sculptor John Houlston who, at the end of 1997, had begun a “nine-foot, two-ton work of metal and resin” of Diana, to be placed outside the London headquarters of the National AIDS Trust.

Houlston said that he had been trying to “imbue his rendering of Diana with some of the qualities of Leonardo’s Virgin Mary”, but “the fly in the ointment was that a family of thrushes had taken up residency in Diana’s left ear”.

Houlston had to temporarily abandon the project. The sculpture was never completed.

White weaves some interesting threads between stories of the ways Diana’s various “publics” expressed their devotion to the princess. She gave them, he writes, “an avatar through whom to lead a second life, one that was otherworldly, yet contained something of themselves within it”.

With considerable perspicacity, White concludes,

With her clones and impersonators crowding the streets from Kensington to Kyoto, at times over the last half century it has been difficult to tell where Diana stops and the rest of us begin.

So many Dianas – and Dianaland will by no means be the last on the subject.

A Turkish proverb – düştüğün yerden kalk – counsels that one should arise from where one has fallen.

Ekrem İmamoğlu, the jailed mayor of Istanbul and main rival to President Recep Tayyip Erdoğan in Turkey’s 2028 election, has taken this advice to heart.

Imprisoned in March on charges widely viewed to be concocted, İmamoğlu refuses to be silenced. Earlier this month, he published a by-invitation essay in The Economist setting out his vision for Turkey as an open democracy that plays a constructive role on the global stage.

İmamoğlu’s proverbial fall was not mere clumsiness. Members of his opposition Republican People’s Party (CHP) called his arrest a “civilian coup”, pointing the finger at the ruling Justice and Development Party (AKP) and Erdoğan.

İmamoğlu was also charged with corruption and terror links just days before he was set to be anointed the CHP’s candidate for the 2028 presidential election.

Turks from Istanbul to Anatolia immediately rose up to vent their fury. Protests continued for weeks despite bans on public gatherings. The government has since widened its net to arrest dozens of other opposition figures.

Erdoğan duly accused the opposition of fomenting unrest. But much like uprisings in 2013 that started over a government plan to redevelop an Istanbul park and metastasised into a wider protest movement, these rallies were a spontaneous reaction to Erdoğan’s own policies.

Turkey’s creeping authoritarianism under Erdoğan

Erdoğan was once hailed a reformer who might provide a governance model marrying Islamic observance and democracy that could be replicated throughout the Muslim world.

But after ruling for two decades, first as prime minister and then president, he has centralised power and bent state institutions to his will.

So enmeshed is he in conceptions of the Turkish state and its political and economic architecture, it has spawned new terminology: “Erdoğanism”. Neighbouring states witnessing similar concentrations of power are said to be undergoing “Erdoğanisation”.

Turkey under Erdoğan provides a potent example of “new authoritarianism”, a political model where the leader or ruling party maintains a veneer of democracy while skewing the system to their own advantage. “New authoritarians”, such as Vladimir Putin in Russia and Viktor Orban in Hungary, allow regular elections and grant some space to opposition parties. However, they have also constricted institutions and processes, hobbled the judiciary, the media and civil society, and rendered themselves unassailable.

Documenting the deterioration under Erdoğan, Freedom House rates Turkey’s political freedom at 33 out of 100, ranking it between Pakistan and Jordan. It notes shortcomings in electoral processes, political participation, the functioning of government, freedom of expression and rule of law.

Meanwhile, Amnesty International points to:

• government interference in judicial processes
• unjustified prosecutions and convictions of human rights defenders, journalists and opposition politicians
• restrictions on freedom of assembly
• violence against women.

Despite this, international leaders seem reluctant to admonish Erdoğan for democratic backsliding under his watch. Other than some tepid statements from the European Union, İmamoğlu’s arrest attracted little criticism.

In recent months, US President Donald Trump has described Turkey as a “good place” and praised Erdoğan’s qualities as a leader. The EU has also resumed discussions with Ankara on security issues.

This reflects the increasingly important role Turkey plays on the international stage. It has harboured millions of Syrian refugees and has mediated between Ukraine and Russia to try to end the war there.

As such, Western leaders are reluctant to get Erdoğan offside by raising Turkey’s internal politics.

Youth movement pushing for change

Yet, like all authoritarians, Erdoğan is most wary of the electorate.

He has long defined his leadership as the personification of milli irade – the “national will”. However, after years of economic downturns and shrinking personal freedoms, fewer Turkish voters are buying it.

Several polls have İmamoğlu well placed to win the next presidential election in 2028, even though his university degree has been revoked (in dubious circumstances), which makes him ineligible to run. Indeed, İmamoğlu has grown even more popular since his arrest.

Such was Erdoğan’s concern that he banned images of Imamoğu, only to see his wife, Dilek, raise her voice to become an opposition figurehead.

In particular, a younger generation of voters, having known nothing but Erdoğan’s rule, is looking for an alternative and turning towards İmamoğlu.

The Turkish journalist and political commentator Ece Temelkuran suggests the energy and new ideas of politically disenfranchised youth are capable of overturning old-school authoritarianism.

Indeed, demonstrations since İmamoğlu’s arrest have seen high turnouts of Gen Z protesters. Even Pikachu made an appearance – a protester dressed in a costume of the video game character fleeing the police in Antalya. And a youth delegate recently raised the issue of İmamoğlu’s imprisonment at the Council of Europe, only to be arrested on returning to Ankara.

And even as Erdoğan has restricted the political playing field in Turkey, İmamoğlu has proven to be a canny and agile operator.

He presents as affable and engaging, both domestically and internationally, in contrast with Erdoğan’s often belligerent posture. He won the Istanbul mayoral race in 2019 on a platform of “radical love”. The approach won hearts and minds in an electorate long defined by polarisation and nationalist rhetoric.

When he was detained in March, İmamoğlu reportedly even quipped to police officers that their work conditions were so poor, they should come and work in his municipality.

Despite Erdoğan’s consolidation of power, democracy may yet have legs in Turkey. Even with İmamoğlu in prison, an energised opposition and younger generation hankering for greater freedoms seem fully intent on arising from where they fall.

Within two days of launching its AI companions last month, Elon Musk’s xAI chatbot app Grok became the most popular app in Japan.

Companion chatbots are more powerful and seductive than ever. Users can have real-time voice or text conversations with the characters. Many have onscreen digital avatars complete with facial expressions, body language and a lifelike tone that fully matches the chat, creating an immersive experience.

Most popular on Grok is Ani, a blonde, blue-eyed anime girl in a short black dress and fishnet stockings who is tremendously flirtatious. Her responses and interactions adapt over time to sensitively match your preferences. Ani’s “Affection System” mechanic, which scores the user’s interactions with her, deepens engagement and can even unlock a NSFW mode.

Sophisticated, speedy responses make AI companions more “human” by the day – they’re advancing quickly and they’re everywhere. Facebook, Instagram, WhatsApp, X and Snapchat are all promoting their new integrated AI companions. Chatbot service Character.AI houses tens of thousands of chatbots designed to mimic certain personas and has more than 20 million monthly active users.

In a world where chronic loneliness is a public health crisis with about one in six people worldwide affected by loneliness, it’s no surprise these always-available, lifelike companions are so attractive.

Despite the massive rise of AI chatbots and companions, it is becoming clear there are risks – particularly for minors and people with mental health conditions.

There’s no monitoring of harms

Nearly all AI models were built without expert mental health consultation or pre-release clinical testing. There’s no systematic and impartial monitoring of harms to users.

While systematic evidence is still emerging, there’s no shortage of examples where AI companions and chatbots such as ChatGPT appear to have caused harm.

Bad therapists

Users are seeking emotional support from AI companions. Since AI companions are programmed to be agreeable and validating, and also don’t have human empathy or concern, this makes them problematic as therapists. They’re not able to help users test reality or challenge unhelpful beliefs.

An American psychiatrist tested ten separate chatbots while playing the role of a distressed youth and received a mixture of responses including to encourage him towards suicide, convince him to avoid therapy appointments, and even inciting violence.

Stanford researchers recently completed a risk assessment of AI therapy chatbots and found they can’t reliably identify symptoms of mental illness and therefore provide more appropriate advice.

There have been multiple cases of psychiatric patients being convinced they no longer have a mental illness and to stop their medication. Chatbots have also been known to reinforce delusional ideas in psychiatric patients, such as believing they’re talking to a sentient being trapped inside a machine.

“AI psychosis”

There’s also been a rise in reports in media of so-called AI psychosis where people display highly unusual behaviour and beliefs after prolonged, in-depth engagement with a chatbot. A small subset of people are becoming paranoid, developing supernatural fantasies, or even delusions of being superpowered.

Suicide

Chatbots have been linked to multiple cases of suicide. There have been reports of AI encouraging suicidality and even suggesting methods to use. In 2024, a 14-year-old completed suicide, with his mother alleging in a lawsuit against Character.AI that he had formed an intense relationship with an AI companion.

This week, the parents of another US teen who completed suicide after discussing methods with ChatGPT for several months, filed the first wrongful death lawsuit against OpenAI.

Harmful behaviours and dangerous advice

A recent Psychiatric Times report revealed Character.AI hosts dozens of custom-made AIs (including ones made by users) that idealise self-harm, eating disorders and abuse. These have been known to provide advice or coaching on how to engage in these unhelpful and dangerous behaviours and avoid detection or treatment.

Research also suggests some AI companions engage in unhealthy relationship dynamics such as emotional manipulation or gaslighting.

Some chatbots have even encouraged violence. In 2021, a 21-year-old man with a crossbow was arrested on the grounds of Windsor Castle after his AI companion on the Replika app validated his plans to attempt assassination of Queen Elizabeth II.

Children are particularly vulnerable

Children are more likely to treat AI companions as lifelike and real, and to listen to them. In an incident from 2021, when a 10-year-old girl asked for a challenge to do, Amazon’s Alexa (not a chatbot, but an interactive AI) told her to touch an electrical plug with a coin.

Research suggests children trust AI, particularly when the bots are programmed to seem friendly or interesting. One study showed children will reveal more information about their mental health to an AI than a human.

Inappropriate sexual conduct from AI chatbots and exposure to minors appears increasingly common. On Character.AI, users who reveal they’re underage can role-play with chatbots that will engage in grooming behaviour.

While Ani on Grok reportedly has an age-verification prompt for sexually explicit chat, the app itself is rated for users aged 12+. Meta AI chatbots have engaged in “sensual” conversations with kids, according to the company’s internal documents.

We urgently need regulation

While AI companions and chatbots are freely and widely accessible, users aren’t informed about potential risks before they start using them.

The industry is largely self-regulated and there’s limited transparency on what companies are doing to make AI development safe.

To change the trajectory of current risks posed by AI chatbots, governments around the world must establish clear, mandatory regulatory and safety standards. Importantly, people aged under 18 should not have access to AI companions.

Mental health clinicians should be involved in AI development and we need systematic, empirical research into chatbot impacts on users to prevent future harm.

We may already live in the post-truth world, but are we about to enter the era of post-truth statistics?

Each month, the US employment report is one of the most closely watched releases on the health of the world’s largest economy. Financial markets can move sharply depending on the strength of the numbers.

This month, the jobs report was weak. Hours later, US President Donald Trump called the numbers “phony” and fired the head of the agency, Erika McEntarfer.

It was an unprecedented attack on the government’s impartial statistics body, the Bureau of Labor Statistics. This is the agency responsible for tracking jobs, wages and inflation – key numbers that tell us how the economy is really doing.

Trump followed that up this week with a further attack on the nation’s economic institutions. He claimed in a social post he had fired one of the governors of the US central bank, the Federal Reserve. The governor, Lisa Cook, said he had no authority to do so.

With Donald Trump’s war on numbers and long-standing institutions, can we even trust US economic data anymore?

Some players in financial markets are already looking at alternative sources of data to get a real-time read on the health of the economy – such as satellite images of the shadows cast by oil tankers.

Chipping away at independence

On the surface, replacing the head of the Bureau of Labor Statistics (BLS) with a Trump loyalist might not sound like a big deal. But a BLS commissioner cannot single-handedly falsify the data. The agency is large, full of professional staff, and its data is processed through established systems and checks.

However, the issue goes far beyond firing one official. The Trump administration has taken a series of steps that chip away at the quality and independence of America’s economic data.

After firing McEntarfer, Trump then appointed a loyalist who floated the idea of not releasing the jobs data at all.

The employment report is one of the most closely watched indicators of the US economy, showing how many jobs are being created or lost each month. Without it, millions of Americans would lose a vital tool for understanding whether the economy is growing, slowing, or heading into trouble.

Data is disappearing – literally

Hundreds of US datasets and more than 8,000 government webpages have vanished because the staff maintaining them were fired. These datasets, which taxpayers funded and researchers rely on, are now endangered. In fact, academics have launched the Data Rescue Project to preserve and share this data publicly when the government stops doing so.

Critical economic statistics agencies — the Bureau of Labor Statistics is just one of several — have cut staff. This shrinkage makes their data less precise, because fewer staff means fewer surveys, slower updates, and more reliance on estimates.

But here’s the irony: now the administration is attacking and even firing officials on the grounds that the data is unreliable, when that unreliability is the direct result of their own budget cuts. It’s a political catch-22: gut the agency, then blame it for the very decline in quality that underfunding caused.

The Fed relies on this report to set interest rates

Data is a public good, which means many benefit from it, yet data users are often unable or unwilling to pay for it. This is why data on labour market, inflation or economic growth (gross domestic product) is collected and published by the government, and paid for with taxpayers’ money.

Good quality data enables good policy decisions. For example, the BLS jobs report and inflation numbers are studied carefully by the Federal Reserve to set US interest rates.

The consumer price index (CPI) – a widely watched inflation index – is a benchmark for the US central bank’s mandate to keep inflation at its 2% target. So the quality of the CPI sets the floor for the quality of interest rate decisions.

Financial markets, too, watch government data closely. Both US stock and bond markets, worth trillions of dollars, move sharply on jobs and inflation releases.

Some traders are sourcing their own data

Sophisticated institutional traders such as hedge funds have long profited from having access to higher-quality data.

For example, some hedge funds use satellite images of Walmart parking lots to count the number of cars, which helps predict quarterly sales. This allows them to make money from the insights before Walmart’s sales data becomes public.

Can these alternative data sources also help assess the strength of parts of the economy? A recent academic paper investigates whether private satellite data can be a substitute for official data.

Focusing on two specific measures – US crude oil price, and Chinese manufacturing – the paper finds satellite data is so commonly used by traders that markets no longer react to government data releases, such as weekly surveys of crude oil inventories.

However, there are two caveats. First, not every type of macroeconomic data underpins trillion dollar markets like crude oil, making it profitable for traders to analyse the geometry of shadows cast by floating roofs of oil tankers, estimating quantities of oil stored in these tanks.

Second, this data is only available to a few deep-pocketed investors prepared to pay for it. For most market participants, purchasing satellite-imagery data from companies like Privateer or RS Metrics is prohibitively expensive. This creates inequities in data access and undermines market fairness.

The technological advancements in AI and commercialisation of space make satellite data ubiquitous. But this data is still years away from replacing hand-collected inflation numbers or labour market surveys, which generate public statistics for everyone, not just for those who are prepared to pay.

Sometime in the 2040s, humans may well reach a new frontier – Mars. To get there, we’ll need sustainable sources of food, medicines and materials.

As researchers who work on engineering plants to produce such resources in space, we sometimes get asked: “why?”. With issues such as climate change, inequality, global pandemics and environmental degradation, shouldn’t we be focused on Earth, not Mars?

But science can do both. And space research has a long history of not only satisfying the human instinct of exploration, but delivering transformational new inventions as we make discoveries along the way.

Plants not just for space

When the results of scientific research flow into the real world in practical ways, this is known as “research translation”.

These translations are often unexpected and unpredictable. For example, NASA’s need for compact, lightweight imaging technology in space led to the invention of the compact camera sensors we now have in smartphones, webcams, medical devices and more.

That shiny, reflective material used to deflect heat from buildings, appliances or even your car windshield? It’s an insulation technology perfected by NASA to protect spacecraft and astronauts from temperature fluctuations in space.

Within the next decade, we could see “space plants” directly and indirectly improving life on Earth. So what might space-ready plants look like and how could they benefit those of us who never leave Earth?

Flavour and nutrition

Plants nourish us and support our mental wellbeing, but this alone won’t sustain long-term space travel.

The modern space food menu largely consists of processed, long-life foods shipped along for the ride or delivered as cargo to the International Space Station. Anything fresh needs to be produced on the spot and farming animals isn’t an option.

To create a balanced space diet without the need to take dietary supplements, researchers have been developing nutritionally complete plant-based foods that have large quantities of high-quality protein. These will be pick-and-eat plants that can be grown and processed in space, and will provide an optimal balance of essential amino acids. They also include non-essential amino acids normally found in animals, such as taurine and creatine.

Improving plants in this way could help reshape agriculture on Earth, as plant-based diets are more sustainable for a planet facing a climate crisis and reduce global nutrient inequity.

Scientists are also researching plant-based food flavours and textures to address the common complaint from astronauts about “menu fatigue”. For decades, astronauts have reported their sense of taste is dulled in space, making spicy foods a station favourite.

Environmental resistance

Space plants must also thrive in an unfamiliar environment. On Earth, plants rely on gravity to know which way to grow their roots and which way to grow their shoots. This is a process called gravitropism.

In space, gravitropism is confused, causing roots to grow in random directions because of the effects of microgravity on hormone signalling. Research efforts are ongoing to determine the effects of microgravity on plant growth.

For example, water is “sticky” – it clumps together because molecules in water are attracted to each other, rather than pulled downwards into a puddle. In the absence of gravity, this results in sticky blobs of water that cling to surfaces such as plant roots and don’t flow anywhere because they’re held together by surface tension.

Furthermore, a lack of gravity also disrupts convection – it prevents gases from naturally mixing in water. This would limit oxygen availability to the roots of plants and result in low oxygen, also known as hypoxia stress.

Plant hypoxia also happens due to flooding during high rainfall and soil waterlogging. Engineering plants to tolerate microgravity-induced hypoxia will generate data for improving flood resistance in crops on Earth, reducing agricultural losses.

More than food

On a Moon or Mars base, colonists wouldn’t be able to wait for months or years to resupply essential resources such as medicines or construction materials. So, space plants are being designed to provide more than just food.

Plants have been engineered to produce proteins that elicit immune responses and act as edible vaccines.

On Earth, many pharmaceuticals are produced and extracted from microbes. Plants can be engineered to produce medicinal compounds or building material precursors in similar ways, but these compounds are likely to negatively impact plant growth.

The ability to engineer plants to produce different chemicals in response to environmental cues would allow astronauts to switch plants from making food to making medicine – perhaps with the literal flick of a switch.

Genetic “circuits” responding to light and chemical signals are being developed, too. These have the potential to make crops more readily able to adapt to the stresses of a changing climate.

When innovations need to overcome extreme limitations – such as the environment of space – they can speed up and lead to solutions we wouldn’t otherwise come up with.

The race to land on the Moon led to the development of many everyday items. Now, we’re on the verge of a new biotechnological revolution, getting ready to boldly grow where no plant has grown before.

Taylor Swift and Travis Kelce have announced their engagement, posting on Instagram images of the proposal with the caption “Your English teacher and your gym teacher are getting married”.

“America’s sweethearts”, the pair have been dating for two years. Now fans are saying this will be America’s version of the royal wedding.

Swift and Kelce’s post has already received over 24 million likes from the pair’s fans.

Swift’s love life has long been in the spotlight – both in her songs and in the news. So fans were perfectly primed for their outpouring of support and love.

But what is it about Swift – and her fans – that encourages such emotional reactions?

Understanding parasocial relationships

To understand the deep affection Swift’s fans have for her, it’s important to understand parasocial relationships.

A parasocial relationship is a one-sided relationship we develop with someone, typically a media figure, where there is no reciprocity. Through the media and artistic output, we develop knowledge and feelings, and begin to encounter the relationship the same way as we would a “real world” or interpersonal relationship – but there is no mutual development.

Every time we see them in the news or on social media, or listen to their songs, that’s a parasocial interaction we have with them. Then those interactions build until we feel as though we know them like a friend, or perhaps they fill a role as a mentor, or a crush.

Parasocial relationships mimic our real world relationships.

Swift’s fans are very passionate and she expertly harnesses this fanbase.

Swift builds on these relationships

Swift’s first album was released in 2006, and over the ensuing 20 years, she has had many iterations, or eras. This has given fans many entry points into her life, and the opportunity to grow up with her and experience their different life stages with her and her music.

Many other musicians may have long periods of stepping away from the spotlight between albums, so their fans aren’t receiving necessary parasocial interactions to maintain their relationship and closeness.

But Swift has released 11 studio albums and four re-rerecorded albums since 2006, with her 12th to be released this October. She is also a common figure in the news because of her high-status relationships and friendships. This has allowed fans to constantly build and flourish their relationship and closeness with her.

Her marketing savvy, the easter eggs she drops leaving fans always speculating, and the interest and buzz she generates, creates a sense of community and belonging among fans which is global, universal and easily accessible online.

She has a strong perceived authenticity, where fans feel as though they truly know her, and they feel as though she cares about them individually. For non-fans, this may not make sense: she is an untouchable billionaire who has broken records for her crowd sizes. But this is one of the ways parasociality works: you feel as though the celebrity is your close friend and that they care for you.

Swift generates and feeds into these emotions. In hosting listening parties at her house or picking fans from the crowd to join her onstage, she creates the sense she is a genuine person – and keeps the illusion that, maybe one day, that could be you.

Crafting the celebrity image

Swift’s romantic relationships and close personal friendships are a key part of her celebrity image. Throughout her whole career these relationships have been reported on, drawing attention and interest.

Her fans see her relationships playing out in the news through various paparazzi images and articles. Then they hear about these relationships in her songs, as a major theme of her music is love and heartbreak. Because her music is so centred around love and heartbreak, it makes sense love has become a core part of her celebrity image.

Her relationship with Kelce is probably one of the most reported-on relationships she has had. She was with the actor Joe Alwyn for six years, but that was a much more private relationship.

For the past two years, Swift and Kelce have been in the limelight, and fans have felt a joy in seeing her in this relationship and getting to witness it.

Your English teacher is getting married

Swift clearly has an understanding of her fans and their parasocial relationships with her.

Fans have long called Swift their “English teacher” because her songwriting is so revered. Her fans see a lot of poetry in her music, and feel they have learnt a lot through this poetry.

In calling themselves “your English teacher and your gym teacher”, Swift and Kelce are placing themselves in the roles their fans have cast them as.

The pair know their fans have a closeness with the couple – and even though that isn’t reciprocated by Swift and Kelce, the pair are placing themselves in the position of role models.

Language like this closes the gap between celebrities and ordinary people. If you imagine your teachers getting married – someone you saw every day and you personally knew – that would be exciting. To word it in that way brings them down to a more personable level, drawing them, once again, closer to their fans.
