1/ This new @sciam editorial promotes scientific falsehoods while purporting to dispel them.

Puberty blockers aren't "reversible" in the context of trans medicine. We don't know much about what happens developmentally when *normal* puberty is delayed. scientificamerican.com/article/why-an…
2/ The "reversible" claim refers to the fact that *very* young children who begin puberty much to early, and risk developmental issues, can take PBs to delay puberty until the normal age for puberty (~12 years old). In this context, the effects of PBs are mostly safe.
3/ But we don't have good data on the effects of PBs when puberty is delayed during the time when children would *normally* undergo puberty. And the data we do have is raises many red flags.

PBs are used off-label in trans medicine. They are not approved for this context.
4/ Plus, data shows that nearly 100% of kids who go on PBs continue on to cross-sex hormones, whereas dysphoric children who are not put on PBs desist at a rate of around 85%.

In other words, PBs appear to cement dysphoric feelings in kids who may have otherwise desisted.
5/ SciAm is promoting dangerous scientific falsehoods here. They should be ashamed.

1/ When societies begin denying basic fundamental facts about biology, these are the kinds of absurdities you can expect to see regularly.
2/ We KNOW this isn't fair.

Here are two major reviews from this year in top sports medicine journals. One is even first-authored by a trans woman—Joanna Harper. Conclusions highlighted.

2021 review #1: link.springer.com/article/10.100…
2021 review #2: bjsm.bmj.com/content/early/
3/ The activists used to say "show us the data that trans women who suppress testosterone outperform cis women!"

Well, the data now clearly demonstrate that, and—surprise!—they don't care! They never did. That was just an expedient way to temporarily shut people up.

1/ I used to stutter badly until I was about 5, and then it suddenly vanished, mostly. But then every once in a while I would try to start speaking and simply could not get the first syllable of the first word out. If I tried to force it out, I would stutter.
2/ Once I got passed the first word, I could go on talking stutter-free! But that first word could be a real doozy. I solved that problem by either using a different word with a similar meaning that somehow didn't hang me up, or I'd start the sentence using some...
3/ go-to filler word like "yeah" or "well" before beginning my sentence if I got that weird feeling that a word wasn't going to come out.

Today I get that feeling very rarely, but it does still happen. I've just gotten so good at anticipating it and instantly swapping in a...

The "Marketplace of Ideas" doesn't state that free expression will always result in goodness and truth. It's just that the alternatives are more dangerous and corruptible because they're authoritarian and put us in a bind when deciding who gets to choose what's "good and true."
The MOI correctly assumes that truth exists, but that nobody gets to claim special authority—"it's true because I said it's true!" This means all ideas must be able to be double-checked and criticized, and that *nobody* has the final say.
An incorrect or immoral idea may still emerge as a consensus (it happens a lot!), but the MOI ensures it will not be etched in stone and that alternative ideas, some of which may be closer to truth and goodness, will have a voice and thus a *chance* of becoming the new consensus.

1/ Sex spectrum pseudoscience is being presented as fact by a Texas Democrat in a hearing on trans athletes. He makes the absurd claim that there are 6 (!) biological sexes.

These ideas were embarrassing when they were relegated to Tumblr. Now they're in government proceedings.
2/ The claim that there are 6 sexes is based on the flawed notion that people with variations of sex chromosomes beyond XX & XY are their own unique additional sexes. This demonstrates a very poor understanding of biology.

I wrote an article about it. ⬇️ colinwright.substack.com/p/sex-chromoso…
3/ I also wrote an article explaining why, in great detail, biological sex is not a spectrum.

These articles don't present a fringe opinion in biology. These are mainstream facts that are being twisted and suppressed for political reasons.
