Column: Disinformation is a public health crisis. Here's how scientists and doctors are fighting it

In recent years, disinformation has seemed to be on an inexorable march across the scientific and medical landscape.

Prominent politicians, up to and including the former president, have promoted useless drugs as supposed cures for COVID-19. Partisan attacks on the safety and efficacy of COVID vaccines have expanded into attacks on all vaccines. Established scientific and medical authorities have been vilified on social media and on the airwaves and even been subjected to physical assault.

The sheer volume of lies and misrepresentations injected into the political mainstream has some scientists despairing of ever regaining the public’s attention.

“Scientists really recognize this as a problem, from what they see in the community and read in the news,” says Tara Kirk Sell of Johns Hopkins University’s Center for Health Security. “They see the problems they have from misinformation and disinformation on the public health side and in the medical field and in other areas. They want to figure out how to deal with it. We’re providing some guidance for combating it and making people more resistant to it.”

Sell’s reference is to the “Practical Playbook for Addressing Health Misinformation” just released by her center. The 65-page publication amounts to a road map for identifying misinformation and disinformation and applying the best strategies for counteracting it before it spreads.

It’s part of an emerging genre of advice for scientists, public health officials and others who get confronted by rumors that interfere with their work, or by deliberate falsehoods; the latter is “disinformation,” as opposed to “misinformation,” which may simply be widely accepted misunderstandings that may have innocent sources.

UNICEF, the Yale Institute for Global Health and other organizations published one of the earliest such guides in late 2020, aimed specifically at anti-vaccine misinformation. Others have the broader goal of fighting conspiracy theories in general.

One recommendation that most seem to have in common is to take a strategic approach: Disinformation campaigns can’t be defeated by ad-hoc measures; they require an organized, proactive and targeted approach mounted by credible defenders of science.

The effort is important because the disinformation has more than political consequences; it costs lives. Pseudoscience debunker Peter Hotez calculates that as many as 200,000 Americans may have perished because of COVID after the vaccines were introduced because anti-vaccine propaganda dissuaded them from getting the shots.

Cases of measles, which should have been eradicated in the U.S. years ago, are appearing again because of disinformation about the vaccines. The Centers for Disease Control and Prevention counts more than 20 measles cases so far this year in at least 11 states. That’s about one-third of the 58 cases recorded in all of last year, counted in only the first six weeks of 2024, suggesting that a more serious epidemic may loom on the horizon.

Six cases have occurred in a single school in Florida, a state whose Republican governor, Ron DeSantis, has placed anti-vaccine propaganda at the center of his public health policies. The school’s measles vaccination rate is about 89%, well below the 95% level thought to provide communal immunity protecting even the unvaccinated.

Scientists … see the problems they have from misinformation and disinformation on the public health side, and in the medical field and in other areas. They want to figure out how to deal with it.

— Tara Kirk Sell, Johns Hopkins university

As I’ve reported before, the politicization of anti-COVID measures has turbocharged healthcare disinformation more generally. In part, the reason may be that the pandemic brought public health efforts out of the shadows.

“Often, public health has been an invisible force for good,” Sell told me. “People don’t really notice it because they don’t notice not getting sick and not getting food poisoning.” During the pandemic, however, “people saw public health acting in a more visible way, that made them aware, and sometimes a little bit scared, that sometimes public health measures can be restrictive.”

Sell acknowledges that the battle against disinformation has gotten harder. One reason is that more of it emanates from government sources.

That’s a novel issue. At a simulation exercise on pandemic responses that Sell’s institute hosted for business and public health officials in October 2019, one question that came up was: What if misinformation or disinformation comes from government?

The conclusion was “that’s a crazy question,” Sell told me. “Now, it doesn’t seem that crazy. We’ve seen a lot of it.”

At a House hearing just last week, for instance, Rep. Marjorie Taylor Greene (R-Ga.) staged an attack on COVID vaccines consisting of misleading statistics presented out of context, unverified claims of side effects and flagrant misstatements about the consequences of COVID infection.

As I’ve reported, one of the nation’s most assiduous dispensers of anti-vaccine claptrap does so from an official perch. He’s Florida Surgeon General Joseph Ladapo, who was inserted into his post by DeSantis, who may be the nation’s second-most-dangerous official offender against good sense and sound public health policy.

Ladapo’s approach to the Florida measles outbreak, which includes downplaying the need for children to be vaccinated and allowing parents to make their own decision about sending even unvaccinated children to schools experiencing an outbreak, runs counter to recommendations from the CDC. The CDC places vaccination at the very top of its recommendations for preventing the disease and advises isolating those who may transmit the virus.

A problem of longer standing for anti-disinformation crusaders is encompassed in Brandolini’s Law, coined in 2013 by Alberto Brandolini, an Italian software engineer. Cleaned up, it states, “The amount of energy needed to refute [B.S.] is an order of magnitude bigger than that needed to produce it.”

To put it another way, disinformation peddlers need only make a claim that sounds plausible or might even have a small kernel of truth to influence the unwary. Debunking or refuting their assertions often requires offering nuanced or technical information that doesn’t have the same pizzazz.

Recognizing disinformation techniques and how they implant sticky but erroneous concepts in the minds of laypersons, Sell says, points to some useful rules of engagement. One is the value of “prebunking” — “addressing or refuting potential false information” before it’s widely disseminated, as the Johns Hopkins handbook puts it.

“People are not that creative,” she says. “They use the same stories over and over again with different health threats. You can expect that with any vaccination campaign there will be an infertility rumor, no matter what vaccine it is, or a rumor that a vaccine has been experimented on children. We see that every time. They work because they resonate” with target audiences — such as pregnant women or parents of small children.

“People need to be shown how to recognize disinformation tactics, such as an appeal to emotion” or personal stories of adverse side effects that are claimed to be representative of patients as a whole rather than rare occurrences.

It may also help to highlight the motivations of anti-science propagandists, who spread disinformation “often for social, political or financial gain.” Indeed, as the Washington Post recently documented from tax records, four nonprofit organizations that marketed medical misinformation during the pandemic saw their contributions leap by more than $100 million from 2020 to 2022.

Among them is Children’s Health Defense, the anti-vaccine group founded by Robert F. Kennedy Jr., who is currently trying to ride his anti-vaccine crusade to the Oval Office.

The lessons of the pandemic may help the public health community avoid some of the mistakes that allowed the disinformation lobby to undermine the public’s trust in scientists and medical experts, a crucial factor in its campaigns. The CDC and other public health agencies sometimes changed their recommendations on anti-COVID policies.

That was hardly an unexpected occurrence, since so little was known at first about the virus, its effects and the most suitable treatments. But it gave their adversaries the opening they needed to question the severity of the outbreak or the policy recommendations themselves, and to promote useless nostrums.

“Public health needs to be transparent about the reasons why advice is changing,” Sell says, “explaining that if you didn’t change with new evidence, you would be doing a disservice to the public. Maybe we didn’t do a good enough job in this pandemic in saying we’re going to learn more, and our advice may change. And we’ll do our best to keep you as informed as possible as that advice changes.”

The challenge of fighting the fire hose of falsity being trained on science has made some scientists cynical about the prospects of victory, Sell acknowledges. “The Playbook is not a silver bullet,” she says. “But it helps. There are things to be done, and we can’t give up. Attacking misinformation in as many different ways as possible is something we’re going to have to do.”

After Warner Bros. merger, changes are coming to the historic Paramount lot. Here’s what to expect

After Warner Bros. merger, changes are coming to the historic Paramount lot. Here’s what to expect

With Paramount Skydance’s acquisition of Warner Bros. expected to saddle the combined company with $79 billion in debt, Paramount executives are looking to do away with redundant assets including real estate — and there is a lot of that.

Chief in the public’s imagination are their historic studios in Burbank and Hollywood, where legendary films and television show have been made for generations and continue to operate year-round.

“Both of these studios are in the core [30-mile zone,] the inner circle of where Hollywood talent wants to be,” entertainment property broker Nicole Mihalka of CBRE said. “It’s very prime real estate.”

When Sony and Apollo were bidding for Paramount in early 2024, their plan was to sell the Paramount property, but there is no indication that Paramount would part with its namesake lot.

For now, Paramount’s plan is to keep both studios operating with each studio releasing about 15 films a year, but the goal is to eventually consolidate most of the studio operations around the Warner Bros. lot in Burbank in order to to eliminate redundancies with the Paramount lot on Melrose Avenue, people close to Chief Executive David Ellison said.

Paramount would not look to raze its celebrated studio lot — the oldest operating film studio in Los Angeles — because of various restrictions on historic buildings there. Paramount also has a relatively new post-production facility on site and will likely need to the studio space.

Instead, the plan would be to lease out space for film productions, including those from combined Paramount-HBO streaming operations. Ellison also is considering plans to develop other parts of the 65-acre site for possible retail use, as well as renting space for commercial offices.

The studios’ combined property holdings are vast, and real estate data provider CoStar estimates they have about 12 million square feet of overlapping uses, including their studio campuses, offices and long-term leases in such film centers as Burbank, Hollywood and New York.

Century-old Paramount Pictures Studios is awash in Hollywood history — think Gloria Swanson as Norma Desmond desperately trying to enter its famous gate in “Sunset Boulevard,” and other classics such as “The Godfather,” “Titanic” and “Breakfast at Tiffany’s.”

The lot, however, is a congested warren of stages, offices, trailers and support facilities such as woodworking mills that date to the early 20th century. The layout is byzantine in part because Paramount bought the former rival RKO studio lot from Desilu Productions to create the lot known today.

Warner Bros. occupies 11 million square feet and owns 14 properties totaling 9.5 million square feet, largely in the United States and United Kingdom, CoStar said. About 3 million square feet of that commercial property is in the Los Angeles area.

The firm’s portfolio also includes the sprawling Warner Bros. Studios Leavesden complex in the U.K. and Turner Broadcasting System headquarters in Atlanta.

Paramount Skydance occupies 8 million square feet and owns 14 properties totaling 2.1 million square feet, according to CoStar. In addition to its Hollywood campus, Paramount’s holdings include prominent buildings in New York such as the Ed Sullivan Theater and CBS Broadcast Center.

Warner Bros. operates a 3-million-square-foot lot in Burbank with more than 30 soundstages — along with space for building sets and backlot areas — where famous movies including “Casablanca” and television shows such as “Friends” were filmed. Paramount’s 1.2-million-square-foot Melrose campus anchors a broader network of owned and leased production space, CoStar said.

Paramount’s lot is already cleared for more development. More than a decade ago, Paramount secured city approval to add 1.4 million square feet to its headquarters and some adjacent properties owned by the company.

The redevelopment plan, valued at $700 million in 2016, underwent years of environmental review and public outreach with neighbors and local business owners.

The plan would allow for construction of up to 1.9 million square feet of new stage, production office, support, office, and retail uses, and the removal of up to 537,600 square feet of existing stage, production office, support, office, and retail uses, for a net increase of nearly 1.4 million square feet.

The proposal preserves elements of the past by focusing future development on specific portions of the lot along Melrose and limited areas in the production core, architecture firm Rios said.

The Warner Bros. and Paramount lots “are two of the most prime pieces of real estate in the country,” Mihalka said. “These are legacy assets with a lot of potential to be [tourist] attractions in addition to working studios.”

Hollywood is still reeling from previous mergers, in addition to a sharp pullback in film and television production locally as filmmakers chase tax credits offered overseas and in other states, including New York and New Jersey.

Last year, lawmakers boosted the annual amount allocated to the state’s film and TV tax credit program and expanded the criteria for eligible projects in an attempt to lure production back to California. So far, more than 100 film and TV projects have been awarded tax credits under the revamped program.

The benefits have been slow to materialize, but Mihalka predicts that the tax credits and desirability of working close to home will lead to more studio use in the Los Angeles area, including at Warner Bros. and Paramount.

“These are such prime locations that we’ll see show runners and talent push back on having shows located out of state and insist on being here,” she said. “I think you’re going to see more positive movement here.”

How our AI bots are ignoring their programming and giving hackers superpowers

How our AI bots are ignoring their programming and giving hackers superpowers

Welcome to the age of AI hacking, in which the right prompts make amateurs into master hackers.

A group of cybercriminals recently used off-the-shelf artificial intelligence chatbots to steal data on nearly 200 million taxpayers. The bots provided the code and ready-to-execute plans to bypass firewalls.

Although they were explicitly programmed to refuse to help hackers, the bots were duped into abetting the cybercrime.

According to a recent report from Israeli cybersecurity firm Gambit Security, hackers last month used Claude, the chatbot from Anthropic, to steal 150 gigabytes of data from Mexican government agencies.

Claude initially refused to cooperate with the hacking attempts and even denied requests to cover the hackers’ digital tracks, the experts who discovered the breach said. The group pummelled the bot with more than 1,000 prompts to bypass the safeguards and convince Claude they were allowed to test the system for vulnerabilities.

AI companies have been trying to create unbreakable chains on their AI models to restrain them from helping do things such as generating child sexual content or aiding in sourcing and creating weapons. They hire entire teams to try to break their own chatbots before someone else does.

But in this case, hackers continuously prompted Claude in creative ways and were able to “jailbreak” the chatbot to assist them. When they encountered problems with Claude, the hackers used OpenAI’s ChatGPT for data analysis and to learn which credentials were required to move through the system undetected.

The group used AI to find and exploit vulnerabilities, bypass defences, create backdoors and analyze data along the way to gain control of the systems before they stole 195 million identities from nine Mexican government systems, including tax records, vehicle registration as well as birth and property details.

AI “doesn’t sleep,” Curtis Simpson, chief executive of Gambit Security, said in a blog post. “It collapses the cost of sophistication to near zero.”

“No amount of prevention investment would have made this attack impossible,” he said.

Anthropic did not respond to a request for comment. It told Bloomberg that it had banned the accounts involved and disrupted their activity after an investigation.

OpenAI said it is aware of the attack campaign carried out using Anthropic’s models against the Mexican government agencies.

“We also identified other attempts by the adversary to use our models for activities that violate our usage policies; our models refused to comply with these attempts,” an OpenAI spokesperson said in a statement. “We have banned the accounts used by this adversary and value the outreach from Gambit Security.”

Instances of generative AI-assisted hacking are on the rise, and the threat of cyberattacks from bots acting on their own is no longer science fiction. With AI doing their bidding, novices can cause damage in moments, while experienced hackers can launch many more sophisticated attacks with much less effort.

Earlier this year, Amazon discovered that a low-skilled hacker used commercially available AI to breach 600 firewalls. Another took control of thousands of DJI robot vacuums with help from Claude, and was able to access live video feed, audio and floor plans of strangers.

“The kinds of things we’re seeing today are only the early signs of the kinds of things that AIs will be able to do in a few years,” said Nikola Jurkovic, an expert working on reducing risks from advanced AI. “So we need to urgently prepare.”

Late last year, Anthropic warned that society has reached an “inflection point” in AI use in cybersecurity after disrupting what the company said was a Chinese state-sponsored espionage campaign that used Claude to infiltrate 30 global targets, including financial institutions and government agencies.

Generative AI also has been used to extort companies, create realistic online profiles by North Korean operatives to secure jobs in U.S. Fortune 500 companies, run romance scams and operate a network of Russian propaganda accounts.

Over the last few years, AI models have gone from being able to manage tasks lasting only a few seconds to today’s AI agents working autonomously for many hours. AI’s capability to complete long tasks is doubling every seven months.

“We just don’t actually know what is the upper limit of AI’s capability, because no one’s made benchmarks that are difficult enough so the AI can’t do them,” said Jurkovic, who works at METR, a nonprofit that measures AI system capabilities to cause catastrophic harm to society.

So far, the most common use of AI for hacking has been social engineering. Large language models are used to write convincing emails to dupe people out of their money, causing an eight-fold increase in complaints from older Americans as they lost $4.9 billion in online fraud in 2025.

“The messages used to elicit a click from the target can now be generated on a per-user basis more efficiently and with fewer tell-tale signs of phishing,” such as grammatical and spelling errors, said Cliff Neuman, an associate professor of computer science at USC.

AI companies have been responding using AI to detect attacks, audit code and patch vulnerabilities.

“Ultimately, the big imbalance stems from the need of the good-actors to be secure all the time, and of the bad-actors to be right only once,” Neuman said.

The stakes around AI are rising as it infiltrates every aspect of the economy. Many are concerned that there is insufficient understanding of how to ensure it cannot be misused by bad actors or nudged to go rogue.

Even those at the top of the industry have warned users about the potential misuse of AI.

Dario Amodei, the CEO of Anthropic, has long advocated that the AI systems being built are unpredictable and difficult to control. These AIs have shown behaviors as varied as deception and blackmail, to scheming and cheating by hacking software.

Still, major AI companies — OpenAI, Anthropic, xAI, and Google — signed contracts with the U.S. government to use their AIs in military operations.

This last week, the Pentagon directed federal agencies to phase out Claude after the company refused to back down on its demand that it wouldn’t allow its AI to be used for mass domestic surveillance and fully autonomous weapons.

“The AI systems of today are nowhere near reliable enough to make fully autonomous weapons,” Amodei told CBS News.

iPic movie theater chain files for bankruptcy

The iPic dine-in movie theater chain has filed for Chapter 11 bankruptcy protection and intends to pursue a sale of its assets, citing the difficult post-pandemic theatrical market.

The Boca Raton, Fla.-based company has 13 locations across the U.S., including in Pasadena and Westwood, according to a Feb. 25 filing in U.S. Bankruptcy Court in the Southern District of Florida, West Palm Beach division.

As part of the bankruptcy process, the Pasadena and Westwood theaters will be permanently closed, according to WARN Act notices filed with the state of California’s Employment Development Department.

The company came to its conclusion after “exploring a range of possible alternatives,” iPic Chief Executive Patrick Quinn said in a statement.

“We are committed to continuing our business operations with minimal impact throughout the process and will endeavor to serve our customers with the high standard of care they have come to expect from us,” he said.

The company will keep its current management to maintain day-to-day operations while it goes through the bankruptcy process, iPic said in the statement. The last day of employment for workers in its Pasadena and Westwood locations is April 28, according to a state WARN Act notice. The chain has 1,300 full- and part-time employees, with 193 workers in California.

The theatrical business, including the exhibition industry, still has not recovered from the pandemic’s effect on consumer behavior. Last year, overall box office revenue in the U.S. and Canada totaled about $8.8 billion, up just 1.6% compared with 2024. Even more troubling is that industry revenue in 2025 was down 22.1% compared with pre-pandemic 2019’s totals.

IPic noted those trends in its bankruptcy filing, describing the changes in consumer behavior as “lasting” and blaming the rise of streaming for “fundamentally” altering the movie theater business.

“These industry shifts have directly reduced box office revenues and related ancillary revenues, including food and beverage sales,” the company stated in its bankruptcy filing.

IPic also attributed its decision to rising rents and labor costs.

The company estimated it owed about $141,000 in taxes and about $2.7 million in total unsecured claims. The company’s assets were valued at about $155.3 million, the majority of which coming from theater equipment and furniture. Its liabilities totaled $113.9 million.

The chain had previously filed for bankruptcy protection in 2019.
