In November, Vince Knight decided he’d had capable of Twitter. After much than a decennary connected the social-media platform, Knight — a mathematician astatine Cardiff University, UK — was acrophobic astir the site’s absorption nether its caller owner, entrepreneur Elon Musk, who began laying disconnected immense numbers of unit soon aft helium acquired it. “Twitter is getting uncomfortable,” wrote Knight connected the platform; helium past jumped vessel to Mastodon, a competing service. He says helium simply didn’t privation to enactment Musk’s Twitter immoderate more.

The past fewer weeks person been tumultuous for Twitter. After Musk laid disconnected staff, the tract has repeatedly malfunctioned arsenic the remaining engineers person struggled to support connected apical of issues. Musk has besides said helium wants to instrumentality the level successful a caller direction, encouraging accounts that were antecedently banned to return. Some reports, including 1 from researchers astatine Tufts University successful Medford, Massachusetts, accidental maltreatment is rising connected the level (see go.nature.com/3vcgpfw).

On 11 December, Musk tweeted that his “pronouns are Prosecute/Fauci” successful an evident effort some to mock the transgender and gender-nonconforming rights movements and to malign the departing manager of the US National Institute of Allergy and Infectious Diseases, Anthony Fauci, who has faced maltreatment and decease threats for his relation successful advising the US authorities effect to COVID-19.

Musk’s erratic and confrontational absorption of Twitter has disquieted galore users, including researchers specified arsenic Knight. For hundreds of thousands of scientists, Twitter is simply a sounding board, megaphone and communal room: a spot to broadcast probe findings, statement issues successful academia and interact with radical who they wouldn’t usually conscionable up with.

Should I articulation Mastodon? A scientists’ usher to Twitter’s rival

“I would ne'er beryllium capable to cognize truthful galore scientists without it,” says Oded Rechavi, who works connected transgenerational inheritance astatine Tel Aviv University successful Israel. “It increases ideology successful subject and gives you much opportunities, nary substance wherever you are.”

Since the site’s founding successful 2006, Twitter executives person often asserted that it aims to beryllium thing little than a ‘public municipality square’ of communication; it present claims astir 250 cardinal regular users. At that scale, abuse, misinformation and bots person been ever-present, but for galore researchers, the advantages of rapid, wide connection to each different and an engaged nationalist outweighed these problems.

The menace of Twitter changing radically nether its caller management, oregon possibly disappearing altogether, has raised concerns and questions for researchers. How good has this immense social-media level benefited science, and to what grade has it harmed it? If it disappears, would researchers privation to recreate it elsewhere?

Twitter’s power connected science

No 1 knows however galore researchers person joined Twitter, but this August, Rodrigo Costas Comesana, an accusation idiosyncratic astatine Leiden University successful the Netherlands, and his colleagues published a information acceptable of fractional a cardinal Twitter users1 who are astir apt researchers. (The squad utilized bundle to effort to lucifer details of Twitter profiles to those of authors connected technological papers.) In a similar, smaller 2020 study, Costas and others estimated that astatine slightest 1% of insubstantial authors successful the Web of Science had profiles connected Twitter, with the proportionality varying by country2. A 2014 Nature survey recovered that 13% of researchers utilized Twitter regularly, though respondents were mostly English-speaking and determination would person been self-selection bias (see Nature 512, 126–129; 2014).

How Musk’s takeover mightiness alteration Twitter: what researchers think

Even though galore researchers aren’t connected Twitter, the level has a large relation successful subject communication, according to respective studies. “Typically, astir one-third of each the technological lit gets tweeted,” says Costas, pointing to a 2020 study3 that analysed 12 cardinal papers from 2012–18; by 2018, the proportionality tweeted had astir doubled from 2012 levels, to astir 40%. And during the SARS-CoV-2 pandemic, much than fractional of each diary articles connected COVID-19 published up to April 2021 were mentioned astatine slightest erstwhile connected Twitter4.

All of this tweeting hasn’t needfully led to engagement, however: a pre-pandemic survey by Costas and his squad analysed 1.1 cardinal links to scholarly articles posted connected Twitter up to September 2019. They recovered that fractional of those posts drew nary clicks to the underlying research, whereas 22% received lone 1 oregon 2 clicks5.

But for galore scientists, Twitter has go an indispensable instrumentality for collaboration and find — a root of real-time conversations astir probe papers, league talks and wider topics successful academia. Papers present zip astir technological communities faster acknowledgment to Twitter, says Johann Unger, a linguist astatine Lancaster University, UK, who notes that other accusation is besides shared successful nonstop backstage messages done the site. And its bounds connected tweet magnitude — presently 280 characters — has pushed academics into keeping their commentary pithy, helium adds.

The societal level has flattened hierarchies, throwing radical into conversations careless of geography, seniority oregon specialism. “Academia is characterized by a batch of gatekeeping,” says Daniel Quintana, a scientist astatine the University of Oslo, who has written an e-book connected however scientists tin usage Twitter (https://t4scientists.com). “Twitter provides a fantastic mode to really get your enactment retired there.”

It has besides fixed an influential dependable to radical who mightiness different beryllium excluded, and has helped to broker enactment networks for those who don’t spot radical similar them successful their ain departments, says Sigourney Bonner, co-founder of the #BlackinCancer assemblage and a PhD pupil astatine Cancer Research UK’s Cambridge Institute. “I didn’t conscionable a Black pistillate with a PhD until I started my own,” she says. Movements agreed by hashtags — from #IAmAScientistBecause to #BlackInTheIvory — person often seen Twitter acting arsenic a rallying constituent for discussing cardinal problems successful academia, specified arsenic racism, sexism, harassment and bullying.

Because of its presumption arsenic a pre-eminent nationalist treatment web and its comparatively unfastened data, Twitter has go a hotbed for researchers studying societal reactions to satellite events — successful particular, however accusation spreads connected the network. A Nature investigation of the Scopus database of technological literature, for this article, recovered much than 41,000 articles and league papers that notation Twitter successful the title, abstract oregon keywords. That fig has accrued from conscionable 1 successful 2006 to much than 4,800 successful 2022.

In a wide shared survey from 2018, researchers astatine the Massachusetts Institute of Technology successful Cambridge studied Twitter and recovered that mendacious quality stories connected the tract dispersed overmuch faster than bash existent quality stories — perchance because, they reported, the mendacious quality items had much ‘novelty’ than the existent news6. The mendacious quality besides tended to arouse emotions specified arsenic fear, disgust and surprise.

And successful a 2018 survey of hatred code connected Twitter, Manoel Horta Ribeiro, present a PhD pupil astatine the Swiss Federal Institute of Technology (EPFL) successful Lausanne, and his colleagues recovered that users whose tweets contained hatred code tweeted much often than those who didn’t usage specified language, and were retweeted much often than their less-incendiary counterparts7.

How Facebook, Twitter and different information troves are revolutionizing societal science

These studies and much constituent to the conundrums that Twitter poses for scientists and different users. Like different platforms that are financed mostly by advertisements, Twitter aims mostly to clasp people’s engagement and attention. Accordingly, Twitter’s find algorithm (which surfaces heavy discussed oregon shared messages connected people’s timelines) “prioritizes a precise peculiar benignant of content”, says Renée DiResta, who studies societal networks and misinformation astatine the Stanford Internet Observatory successful California. “People who possibly don’t needfully person an organization credential, but are adept astatine commenting connected a peculiar topic, tin seizure nationalist attention,” she says.

The thought of Twitter arsenic a large democratizer besides doesn’t ever lucifer reality, DiResta adds. Accounts with a large, established pursuing person overmuch greater scope than “your mean subject experts connected the platform”, she says.

And though Twitter’s algorithms elevate humour, delight and entertainment, they tin besides promote performative tweets, dismissive arguments and snide comments that veer into abuse. Real-time disapproval tin swiftly crook ugly, and users tin easy butt successful connected others’ conversations, with hordes of radical sometimes exhorted to insult and mock a circumstantial target.

Twitter has ever struggled to header with however to mean specified accelerated shifts successful online conversation. It’s a occupation that seems apt to worsen present that Musk has made cuts to the company’s unit and its information systems.

Pandemic Twitter

This double-edged quality of Twitter has ne'er been clearer than during the COVID-19 pandemic. Many academics built up ample nationalist followings done their adept analyses astir SARS-CoV-2, and made fruitful connections arsenic scientists rushed to recognize the pandemic. “Twitter was a truly almighty mode to bash accelerated subject successful immoderate of the areas that we were working,” says Carl Bergstrom, an evolutionary biologist astatine the University of Washington successful Seattle. For instance, 1 of his astir important aboriginal collaborators successful trying to recognize and exemplary COVID-19 done Twitter was a hockey statistician, Bergstrom says.

At the aforesaid time, salient COVID-19 researchers experienced insults, maltreatment and sometimes, as a 2021 Nature survey showed, decease threats — often done Twitter (see Nature 598, 250–253; 2021). Meanwhile, immoderate researchers connected the tract oversimplified information, posted alarmist analyses oregon shared outright disinformation, Bergstrom adds. And contempt Twitter’s self-styled estimation arsenic a nationalist municipality quadrate — wherever everyone gathers to spot the aforesaid messages — successful practice, the pandemic showed however users segregate to travel mostly those with akin views, argues accusation idiosyncratic Oliver Johnson astatine the University of Bristol, UK. For instance, those who believed that COVID-19 was a fabrication would thin to travel others who agreed, helium says, whereas others who argued that the mode to woody with the pandemic was to fastener down for a ‘zero COVID’ attack were successful their ain bubble.

Bergstrom thinks the positives of Twitter outweighed the negatives. During the pandemic, it gave the nationalist much transparency astir the uncertain process of subject progressing successful existent time, helium says. And if immoderate audiences wanted to leap connected to messages of technological certainty wherever determination was none, that wasn’t Twitter’s fault, helium adds.

“I don’t deliberation we’ve done a bully occupation of talking successful schoolhouse subject classes astir the process of doing science, and explaining to radical however the societal process of subject operates,” helium says. “When you really spot subject successful the making, it looks very, precise different.”

Days aft Bergstrom spoke to Nature, however, helium locked his ain relationship aft Musk’s mocking tweet astir Fauci. “You can’t person meaningful and productive technological collaboration connected a level tally by [a] right-wing troll who denies subject erstwhile its results are inconvenient to him and conscionable simply to perceive his assemblage cheer,” he wrote connected Mastodon.

Public square, backstage land

Besides Musk’s idiosyncratic views, his changes to Twitter person disquieted plentifulness of scientists — peculiarly due to the fact that helium fired galore radical who enactment connected contented moderation. Scientists person noted, successful particular, a Twitter announcement connected 23 November that it would stop enforcing its COVID-19 misinformation policy. And determination person since been reports that hatred code connected the level is increasing, including successful areas specified arsenic climate science.

“We’ve been having conversations astir if Twitter is present a harmless spot for our enactment to exist, due to the fact that of the mode it’s changing,” says Bonner. “At this infinitesimal successful time, I don’t know.”

Information idiosyncratic Stefanie Haustein astatine the University of Ottawa successful Canada, who has studied the interaction of Twitter connected technological communication, says the changes amusement wherefore it’s concerning that scientists embraced a private, for-profit firm’s level to pass on. “We’re successful the hands of actors whose main involvement is not the greater bully for scholarly communication,” she says.

Researchers leaving the level volition astir apt effort to find a akin social-media replacement, says Rechavi. “I ideate that if Twitter stops being the spot for scientists to be, past it’ll beryllium replaced by thing else,” helium says. “I conscionable can’t ideate going backmost to being disconnected from the remainder of the subject world.”

But Bonner says she doesn’t deliberation there’s yet a abstraction akin to Twitter. Dynamics connected Instagram, wherever #BlackinCancer has a foothold, are drastically different, with little speech and little speechmaking of posts. And connected Mastodon, the open-source alternate to Twitter that Bergstrom and Knight joined, users tin station longer messages, but the dynamics of the level deliberately marque it harder to observe oregon brushwood messages from users 1 doesn’t straight follow, making communities much siloed and fragmented. (User numbers are inactive tiny compared with Twitter, estimated astatine immoderate 2.5 cardinal successful aboriginal December.)

“A societal web is ever lone palmy if it’s got capable people, and if it’s got the close people,” says Haustein. “It requires millions of radical to determination from 1 spot to the other.” Even if that happens, she says, you request to rebuild the aforesaid networks and structures that existed connected Twitter — which is proving hard due to the fact that of the mode that power of Mastodon is distributed crossed servers, making it hard for those who were connected Twitter to reconnect.

Still, Quintana is hopeful: “Despite the information that I’ve astir apt got 10 times much followers connected Twitter, the worldly that I posted is getting astir the aforesaid magnitude of engagement connected Mastodon,” helium says.

For many, the tweet astir Fauci was a last straw. Afterwards, a caller question of scientists decided to permission Twitter. But immoderate are encouraging their colleagues to instrumentality around. Rechavi emphasizes that Twitter has had a important relation successful research: “I anticipation it survives,” helium says.

And, though the platform’s worst qualities are becoming much common, accidental researchers who spoke to Nature for this article, determination is inactive a request for trained scientists to supply their expertise and constituent radical to the champion sources of evidence-based information. In reply to Bergstrom’s farewell, Trish Greenhalgh, a wellness idiosyncratic astatine the University of Oxford, UK, argued that radical similar him are inactive needed, and that she feels duty-bound to transportation on: “We tin and indispensable instrumentality astir and station sensible technological tweets. I’m staying.”
