Just one week to go to the Anti-Autocracy Summit on 4 December. An overview of the program is now available at: www.scibeh.org/event... An exciting lineup of contributors. Please register if you want to attend, so you will receive Zoom link on the day.
Anti-Autocracy Summit | SciBeh
Image from Jon Tyson on Unsplash Description In an era of creeping authoritarianism, increasing threats to academic freedom, and the politicisation of science, many researchers, communicators, and institutions have launched initiatives to safeguard open inquiry and evidence-based discourse. The Anti-Autocracy Summit brings these efforts together.

Let me tell you what the upshot is from the now-dropped Georgia January 6 case:

A rich white man can with impunity plot to overthrow our government with 18 co-defendants—in a plot with a death toll—if a Black woman involved in the investigation had inadvisable sex.

*That* is how racist America is.

"By 2025, Brexit had reduced UK GDP by 6% to 8%, with the impact accumulating gradually over time. We estimate that investment was reduced by between 12% and 18%, employment by 3% to 4% and productivity by 3% to 4%"

I’m a past winner of the Orwell Prize & won partly because I exposed Vote Leave’s unlawful activities.

Michael Gove was its co-convener & refused to answer a single q. He’s now a judge of the prize & our world is truly one that Orwell would recognise

I swore an oath to the Constitution in 1986. I've upheld it through 25 years of service and every day since I retired.

If Trump's trying to intimidate me, it won’t work. I’ve given too much to our country to be silenced by bullies who care more about power than the Constitution.

Public health suffers when those in power dismiss knowledge

Autism and Vaccines Questions and Concerns | Page 2 of 9 | All pages For Everyone Nov. 19, 2025 Key points The claim "vaccines do not cause autism" is not an evidence-based claim because studies have not ruled out the possibility that infant vaccines cause autism. Studies supporting a link have been ignored by health authorities. HHS has launched a comprehensive assessment of the causes of autism, including investigations on plausible biologic mechanisms and potential causal links.

Now it is 2025. And as of a few days ago, the CDC website has seemingly been taken over by Twitter cranks because scientific information has been replaced by outright disinformation -- that is, information that has been verifiably debunked over and over again. Without much room for ambiguity.

The paper started out with "Imagine a world in which it is not medical knowledge but a free-for-all opinion market on Twitter that determines whether a newly emergent strain of avian flu is really contagious to humans. This dystopian future is still just that—a possible future."

That was 2017

General Audience SummaryImagine a world that considers knowledge to be “elitist.” Imagine a world in which it is not medical knowledgebut a free-for-all opinion market on Twitter that determines whether a newly emergent strain of avian flu isreally contagious to humans. This dystopian future is still just that—a possible future. However, there are signsthat public discourse is evolving in this direction: terms such as “post-truth” and “fake news,” largely unknown until 2016, have exploded into media and public discourse. This article explores the growing abundance of misinformation in the public sphere, how it influences people, and how to counter it. We show how misinformation can have an adverse impact on society, for example by predisposing parents to make disadvantageous medical decisions for their children. We argue that for countermeasures to be effective, they must be informed by the larger political, technological, and societal context.

A little retrospective can be helpful at times to work out what has been happening and what was knowable. Let's travel back in time to 2017 (~8 years ago) when I was lead author on a paper about the post-truth world. doi.org/10.1016/j.ja...

The EU has published a world-first risk landscape report under the #DSA.

It flags systemic risks on big platforms — from illegal content to generative AI— and tracks how platforms are addressing them.

More transparency. More accountability.
