Among health "experts" who tweeted about Monkeypox, there was a dramatic tendency to get basic facts wrong.

For example, many claimed risk wasn't especially heightened among gay men.

PhDs were among the worst misinformation spreaders. Image
Being an "expert", being "credentialed", having "studied" something and so on, is not sufficient to make someone truly credible, to endow their words with reliability.

Being right is, and most popular "experts" were usually not right.

Obama, Trump, and Biden all stated that they wanted to launch massive projects to beat cancer.

Each of them presided over the slow defeat of cancer.

In fact, progress towards the total defeat of cancer is happening all the time🧵 Image
New cancer treatments are coming out all the time.

In fact, the number of approvals for new indications has increased at an accelerating rate over the past half-century.

Part of that probably reflects that the population is getting older, and so needs these more. Image
The population is getting older largely because other causes of death like heart disease and stroke are also being defeated.

But I digress. What have those new drugs done for mortality? Image

The acute toxicity of glyphosate is considerably less than that for common substances like vitamin D, caffeine, aspirin, and even table salt.

Glyphosate thread🧵 Image
There's a crowd of people opposed to glyphosate for various health reasons, but they're virtually all poorly supported. The claims are more about potential than real risks.

One of their responses to acute toxicity data is to reply that they're interested in "chronic toxicity". Image
What they mean by chronic toxicity is long-term effects of low-level exposure.

Of which there are seemingly none.

Ironically, all the meaningful evidence used to suggest chronic harms is acute evidence: results of poorly-run experiments with short-term high-dose exposures!

The Floyd Effect had precedent.

In Baltimore, the death of Freddie Gray came with a large and immediate uptick in the number of homicides. Image
Police pulled back right away.

The arrest rate plummeted. Image
The number of shootings soared far beyond what had happened in recent years. Image

The revolution in organ transplants is here thanks to gene editing.

A 62-year-old man on dialysis needed a new kidney. Doctors implanted him with a pig's kidney that had been given 69 edits to be human-compatible.

He immediately stopped needing dialysis. Image
This man was insanely unhealthy before and after the operation, but at least the organ transplant worked.

On day eight he had his only hiccup, a rejection episode that was easily overcome with a hit from some monoclonal antibodies and some corticosteroids.Image
For background on how insanely unhealthy this man was, just look at his prior history.

He did die 52 days after the operation, but it was still a success. He died from an unrelated heart attack, with no evidence of xenotransplant rejection, and he had stable kidney function.Image

It's often said that you can't see behavioral phenotypes, but that's just not true.

BMI is a well-known behavioral phenotype that you can see.

Like other behavioral traits, the BMI polygenic score is enriched for expression in brain tissue rather than, say, adipose tissue.Image
The chart above was a 2020 replication of a 2015 result: Image
That result also replicated in another 2020 study: Image

High schoolers think it's funny to self-report being transgender.

This makes estimates of trans percentages and other stats unreliable.

Students who self-report as trans also frequently report being blind 7-foot-tall crackheads who belong to a gang and never visit the dentist. Image
The study is from 2014, and of course, we might "know" (who can say, given the nutty response patterns?) that transgender numbers have greatly increased since then.

In a 2017 follow-up it was found that the issue remained.
Cutting out just the most obvious "mischievous responders" halved the rates of "LGBQ-Heterosexual disparity" in 20 a composite of 20 different health measures.

This one didn't deal with trans identity so much, but it's probably even more affected than general gay results. Image
