Someone sent this to me earnestly, but, honestly, if it weren't convincing parents to not vaccinate their kids :(

To someone with a medical background and actually...you know... Relevant statistical and educational experience... All of these comments laughable.

Sigh.
My spit take moment
Vaccinating children who got control (100% of enrolled parents wanted their children to get vaccinated! It was a voluntary study!) is supremely ethical. Vaccines save lives even covid vaccines and youngest lives. This awful beast turns the **best decision of the RCT** into evil.
Dr. Anthony Hinton, consultant surgeon with 30 years of experience in the NHS is obviously extremely unaware of pediatric statistics of myocarditis blood work detections in pediatrics, including after athletic events.
You can literally say all of the same things by saying "I graduated with an arts degree and did a PhD in political economy".

It's well understood that millions of undergrads/grads are FORCED to take statistics courses for their degrees. None are experts in statistics.

Fun child psychiatry fact!

If we analyze a group of 40-year-old adults with the same diagnostic criteria & screening as we use currently on children, we get virtually identical rates of autism.

"Exploding rates of autism" likely a reflection of our exploding understanding.
A 2025 Canadian study estimated 1.8% autism prevalence in adults, similar to child rates, showing diagnosis consistency across ages despite evolving awareness.

/2
From 2011-2022 US data found increased autism diagnoses in children, alongside rises in young adult diagnoses simultaneously, not lagged. This implies that it is not something new to this generation.

New JAMA study (2025) claims social media use → increased depression in 9-13yo.

🧵But let’s dissect:

overall:
* Within-person effects: β=0.07-0.09 (small/medium)
* No between-person effects (β=-0.01)
* 4 waves, n=11,876, caregiver-reported depressive symptoms

1/🧵 Image
The study is here:



However, I have a lot of critiques of this study and its conclusions.

Let's dig in:

Critique: Annual self report scale vs actual tracking

The more that passive tracking (e.g., screen time logs) are used in studies, the weaker the links to mental health are shown.

We currently have almost zero explanatory power for autism aside from some very obscure genetic and prenatal influences.

We already know what has caused the autism "epidemic"... Increased awareness, broader diagnoses, and more screening/requests for assessment.
Bobby Kennedy frequently likes to say it was "1 in 10000 when [he] was a kid". It was not. Studies have shown that if we used modern diagnostics on we would arrive at similar rates, and syndromic presentations of youth for neurodiversity were IDENTICAL to those in the 80s.

/2
When Bobby was a kid, there were more dropouts, "special kids" and a whole assortment of bad names/labels that we now understand better as the extreme neurodiversity that humanity expresses. These poor autistic classmates of RFK were ostracized and stigmatized as "bad"

🚨Countering COVID Myths:🚨

❌Myth: "Lockdowns definitely caused massive learning loss"

✅Reality: Using a large set (n=2mil) of Ontario students, we see more improvements then losses, and trend of older students doing better than younger students.

/1Image
As an example of the statistical reason why I can say the above is a myth, zoom in on ALL the grade 3 scores (Grade 3 did the "worst")

Looking at the distribution, we see more deteriorations (52%) than improvements (45% of scores) achievement scores, but its very broad!

/2Image
Even if we take the "worst example" of grade 3 loss (Grade 3 writing), we see more deteriorations (58% of schools) than improvements, but the distribution is wide and 40% of schools showed improvements.

Vaccines and "placebo control"

Placebo-controlled trials compare a vaccine to an inactive substance (placebo). This helps measure how effective the vaccine is. In the case of vaccines, often, the placebo is not "saline", but rather a previous vaccine or vaccine solution.

/1Image
When a safe, effective vaccine already exists, using an inactive placebo means some participants are deliberately left unprotected against disease. This creates unnecessary harm.

/2
Ethical standards require minimizing harm and offering participants the best available care. When a proven vaccine exists, denying it to anyone—regardless of location—is unethical.

🚨🇨🇦Correcting Disinfo🇨🇦🚨
"COVID vaccination didn't work"

In Canada during the Delta wave, vaccination prevented infection (unvaccinated 6x higher chance of being infected). As well, being unvaccinated led to a 22X chance of being hospitalized and an 18X chance of dying.

/1Image
For confirmed infections, the IFR for unvaccinated was a whopping 2.4%. The IFR for being vaccinated was much lower, both due to preventing infection and reducing the consequences of it.

Delta was a very deadly strain, and unvaccinated people died/suffered the most.

/2 Image
When Omicron hit, it was a strain that evaded vaccinations, leading to enormous numbers of infections, even in vaccinated people.

However, the immunity protection vs hospitalization and death was still enormous, and unvaccinated Canadians were 12X more likely to die.
