NEW: There are widespread concerns that AI will reduce our critical-thinking skills. My story for @nature.com today looks at how to maintain those skills — and teach them to students. I found some fascinating science on critical thinking + useful tips for us all 🧠 www.nature.com/articles/d41...

How to stay smart in the age of AI: the science of critical thinking
There is growing concern that AI can blunt memory and reasoning. But science shows ways to keep the brain sharp.

Meanwhile, on a population level, policies could improve education & healthy food, cut smoking & air pollution. And researchers agree that dementia risk reduction should start early in life & focus on those at most risk ie LMICs and poorer backgrounds in HICs. 10/10 www.nature.com/articles/d41...

How to avoid dementia — what the science really says
Ambitious studies have been examining the protective effects of diet, exercise and socializing — with surprising results.

So what does that mean we should do ourselves? Researchers agree it makes sense to eat healthily, exercise, socialize, keep our brains active. The evidence is uncertain about whether it will lower dementia risks - but it does help prevent strokes/heart attacks and make us feel better. 9/10

And, despite the almost accepted wisdom that the shingles vaccine lowers dementia risk, there is debate here too. New analyses from ‪@mendelrandom.bsky.social‬ & others did not find the vaccine linked to lower dementia diagnoses. 8/10 www.youtube.com/watch?v=qlTn...

Helen Pearson @helenpearson.bsky.social · 07/07/2026
Another worry is that there’s too much emphasis in dementia on personal responsibility, when many important risk factors — such as air pollution, education, access to healthy food — are outside our control. These things require policy action. 7/10

Proponents argue that any reduction in cognitive decline is worthwhile on a population level. Critics are concerned that the programmes are costly and won’t move the needle much. 6/10

Helen Pearson @helenpearson.bsky.social · 07/07/2026
These intensive interventions have small effects — a benefit equivalent to a small/modest boost on some cognitive tests, at best. None has been shown to reduce incidence of dementia. There is a lively debate about what the effect sizes mean in terms of actual impact on the brain. 5/10

Helen Pearson @helenpearson.bsky.social · 07/07/2026
A growing number of ambitious clinical trials (e.g. FINGER, POINTER ) have tested the effects of ‘lifestyle interventions’, which provide intensive help to overhaul people’s diet, exercise, socializing, heart and brain health. The goal is to reduce risks of cognitive decline and dementia. 4/10

Thread of the day Trust in science is “politically polarized in the US. Confidence has fallen among Republican leaning people but not Democrats. This has partly been powered by the populist view that scientists are part of an intellectual elite who do not represent the views of ordinary people.”

That influencers are "trusted" less than journalists is interesting imo when it comes to how surveys relate to actual trust in scientists (or any profession). Which professional group is booming and which one is withering away? Which group do people actually trust in practice, not on paper?

And people are increasingly questioning evidence on divisive issues such as vaccines - another big problem. That’s partly because scientific information is being drowned out on social media. Some say scientists are losing influence, not trust. 8/9 My story: www.nature.com/articles/d41...

The threat now, say some researchers, is that the Trump administration is using the idea that science is not trustworthy as one reason to justify cuts to research and the undermining of evidence-based approaches such as vaccines. 7/9

In the United States, the proportion of people with some confidence in the scientific community has been stably high over decades. But the proportion with a great deal of confidence fell in 2022. This is part of a wider loss of trust in institutions — companies, political bodies, media. 4/9

Helen Pearson @helenpearson.bsky.social · 01/07/2026
Other data show that scientists are one of the most trusted professions — similar to teachers and doctors. Journalists and politicians rank far lower. So there’s no global crisis of trust in science. But the idea of a crisis has become shorthand for a range of complex problems. 3/9

In fact, surveys suggest that public trust in science is fairly high globally. One worldwide 2022-23 survey reported a moderate to high average trust score of 3.6 out of 5, with some variation between countries. Other surveys show a similar picture. 2/9
