What is the real cause of the autism and ADHD epidemics?
It's not what RFK Jr thinks. In fact, it's incredibly simple and mostly to do with how we define and assess the conditions.

My new piece looks at the Last Ditch bar/masking shenanigans and how people have always misunderstood disability and COVID-19 risk.
Also, why mask mandates don't really make sense to me in 2026.

A 2024 paper went massively viral for claiming that COVID-19 vaccines caused lots of excess deaths. I complained to the journal about it at the time.
It was recently retracted. What went wrong and why did it take so long?

Despite the avalanche of evidence and documented problems, the French government still has not acted... Those who enabled this problematic research are still in their positions.
We can add that some ethics officials are still trying to lie in order to protect the IHU and its unethical studies, including someone working at @ARSPaca (cestvraica.com/debunk/le-mon…)
We are waiting for a firm response from the French government and the institutions. The future of French research and its reputation are at stake.

Malgré l'avalanche de preuves et de problèmes constatés, le gouvernement français n'a toujours pas agi... Ceux qui ont permis ces recherches problématiques sont toujours en poste.
On ajoute que certains responsables éthiques tentent encore de mentir pour protéger l'IHU et ses études non éthiques, notamment quelqu'un travaillant à @ARSPaca (cestvraica.com/debunk/le-mon…)
Nous attendons une réaction ferme du gouvernement français et des institutions. Il en va de l'avenir de la recherche française et de sa réputation.
