With the rapid expansion of AI and large language models now incorporated into every sector, it seems sensible to ask some basic questions.

In Skeptical Inquirer this month, I do just that. 🔗https://skepticalinquirer.org/exclusive/can-you-trust-ai-to-give-health-advice/ #science #AI

Research “output.” A term that reduces a painstaking, often gruelling, years-long endeavour to a commodity, undermining the profound intellectual effort behind each publication.

Thousands of products, from supplements to saunas, claim to "boost #immunity." But does the claim have a scientific basis?

Actually, no. It's not possible to BOOST THE IMMUNE SYSTEM. Don't be snagged by marketing hooks. Learn the science and ignore the grifters. #health

In this month's column in Skeptical Inquirer, I look at seed oils—the latest faceless entity being scapegoated by wellness influencers (and public health officials).

So, what does science say?

Cellphones & social media have extended their tendrils into every facet of our lives. We're connected 24/7 to more data than we can possibly process. This takes a toll on our attention.

How is this affecting our exercise training sessions? 🧵1/7 #health #exercise

I don't think I’ve ever seen one face shill for so many brands. How can a science educator stay objective with conflicts of interest seemingly in every corner of health and cosmetics?

Can mindfulness make you a better thinker? I think so.
My latest for @SkeptInquirer (6 min).

Don't judge/comment unless you're willing to read my argument in full. Hot takes not welcome.

-Supplements
-Ozempic
-Ice Baths
-Alternative Therapies
-Placebo Products
-Much, much more

I've done martial arts since I was 8 years old and watched #UFC for over two decades. I remained a fan despite a steady decline in the company's values and its promotion of harmful pseudoscience.

Now, I'm officially done.

Why is a neuroscientist advising on dietary supplements? Because he sells them, endorses them, and is sponsored by them. 💰💰💰

Do you know who doesn't endorse supplements? Qualified nutritionists and dietitians—because most supplements don't work.

New meta-analysis (n=31) shows analytical thinking is the strongest predictor of one's ability to discriminate between true & false news.

Takeaway: Create space between you and the headline. Don't react. Reflect!

Tally just ticked past 1900 signatures. Please keep spreading the word about the letter & asking people to sign. It's important to make the Royal Society aware (at their meeting on 03 March) just how much the scientific community wants them to speak up for their values. forms.gle/SfsDemyS8QhP...
