Simple reminders to think before sharing beat fact-checking at fighting misinformation on social media

voxeu

• An experiment with 10,000 X users during the 2024 election found that nudging people to "think carefully before retweeting" reduced false news sharing more effectively than fact-checking interventions
• Users struggled to distinguish true from false news stories, rating them almost equally credible, though they could easily identify partisan bias
• Anti-misinformation interventions work best when users also see credible, mainstream news content that helps anchor their judgment about what's true

Companies are rushing to deploy AI faster than they can verify it actually works

• AI can now generate code and content at superhuman speed, but companies struggle to verify whether these outputs are accurate, safe, or useful before deploying them • This creates a dangerous gap where businesses ship unverified AI work due to competitive pressure, potentially accumulating hidden risks that could cause major failures • The companies that will succeed won't be those that deploy AI fastest, but those that can reliably verify and take responsibility for what their AI systems produce

When Environmental Cleanup Costs Get So High That Regulators Stop Enforcing the Law

harvard_corpgov

• Companies like Diversified Energy accumulate thousands of unproductive oil wells and coal mines they can't afford to clean up, creating cleanup bills ($3.3-3.8 billion) that far exceed their ability to pay ($1.05 billion revenue).
• Regulators avoid aggressive enforcement because forcing these companies into bankruptcy would leave taxpayers responsible for environmental remediation, creating a perverse "too liable to regulate" dynamic.
• Well-capitalized firms exploit this system by selling their dirtiest, most expensive-to-clean assets to undercapitalized buyers, effectively dodging cleanup responsibilities while keeping toxic sites limping along indefinitely.

The HIV Drug That Could End New Infections Shows Why Trump's Proposed NIH Cuts Are So Dangerous

think_global_health

• Lenacapavir, a twice-yearly injection that prevents nearly all HIV infections, was developed using decades of NIH-funded basic research at the University of Utah starting in 1996
• The Trump administration has proposed cutting NIH funding by 40% from $48 billion to $27.9 billion, which would eliminate the kind of long-term basic research that made this breakthrough possible
• Every FDA-approved drug in the 2010s relied on NIH-funded research, and economists estimate each dollar of NIH funding generates $2.56 in economic activity

Iran's Closure of the Strait of Hormuz Shows How Maritime Coercion Just Got Cheaper and More Effective

hoover

• Iran has effectively shut down the Strait of Hormuz using inexpensive weapons like sea mines and shore-based missiles, demonstrating that a determined state can disrupt global commerce without winning naval battles
• The strategy works by targeting commercial confidence rather than ships directly—insurance costs skyrocket and shipping companies suspend operations before vessels are even attacked
• This playbook could easily migrate to other chokepoints like the South China Sea, where China has been building the infrastructure to impose similar control over critical shipping lanes
