One of our most striking findings: the misinformation premium
Across all platforms except LinkedIn, accounts spreading misinformation get more reach per follower than credible accounts
On YouTube: low-credibility accounts get 8x more interactions per follower than high-credibility ones

What we found:
⚠️ TikTok has the highest prevalence of misinformation: 20% of posts on public-interest topics contain false or misleading info.
Facebook is 2nd at 13%
LinkedIn has the lowest prevalence at just 2%, showing platforms can design systems that don’t reward falsehoods

Claims that DMSO can treat everything from pain to cancer often rely on anecdotes—not solid clinical evidence. Science Feedback reviewed these claims and found major gaps.

One of their graphs compared mortality rates in vaccinated vs. unvaccinated people.
It looked like vaccinated people had higher mortality.
But that conclusion ignores a crucial question. 👇

🚩 Another major issue: numerous scientists cited in the report said it misinterpreted their work! E.g. @hausfath.bsky.social www.theclimatebrink.com/p/how-the-do...
🚩 First red flag: The report was written by 5 known climate contrarians, not topic experts.
That alone doesn’t invalidate it—but other issues do.
For example, it lacked proper peer review.
In contrast, IPCC reports involve hundreds of authors and a transparent review process.

🔴Under the DSA, Very Large Online Platforms must enforce EU laws, including the 2022 ban on Russian state media. The investigation found X’s content moderation slow, inconsistent, and showing linguistic bias, allowing disinformation to circulate widely.

▪️Despite being provided w/ detailed behavioural patterns of the sanctioned Russian operation Doppelgänger, X failed to act swiftly.Most flagged posts remained live until the campaign was complete; whereas on @bsky.app, the platform removed around 70% of Doppelgänger accounts within three days after.

First #heatwave of 2025 hit the UK last weekend, with temps 🌡️ above 32°C in southeast England. It's well-established that climate change is increasing the frequency and severity of heatwaves, but last week, World Weather Attribution scientists specifically analyzed this event's climate change ties.

A common tactic behind #vaccine #misinformation is to misrepresent published studies, sometimes by making unfounded extrapolations, thereby creating the illusion that claims of vaccine harms are scientifically substantiated.

You’ve probably come across claims by “Frank Bergman” from #SlayNews — a site known for spreading harmful misinformation on climate, health, and politics. It’s gone viral multiple times, but who is behind it?

As climate scientist Dr. @hausfath.bsky.social explained to Science Feedback:
“We are confident broadly that both winters and the coldest days of the year are warming rapidly pretty much everywhere, and faster than annual average temperatures have been warming.”

Why do cold snaps persist if the Earth is warming? This question keeps popping up—sometimes from curiosity, but often as rhetoric for climate denial.

The International Energy Agency warns AI's energy demand could double by 2026, but estimating per-query impacts is tough. While comparisons to flight emissions oversimplify the issue, it's clear that AI’s rapid growth is driving higher energy demands and emissions.

As AI adoption grows, so do concerns about its environmental impact. But estimating the footprint of tools like #ChatGPT is more complex than viral posts suggest.
