I wrote a little bit about the "missing heritability" question and several recent studies that have brought it to a close. A short 🧵
The missing heritability question is now (mostly) answered

We wrote the Strain on scientific publishing to highlight the problems of time & trust. With a fantastic group of co-authors, we present The Drain of Scientific Publishing:

Super relevant to ground the critique on scientific publishing. And the cause is pretty simple: the product they sell is made and refined for free, to then charge for it to the same community
What is the most profitable industry in the world, this side of the law? Not oil, not IT, not pharma.

It's *scientific publishing*.

We call this the Drain of Scientific Publishing.

I’ve spent the last 8 years(!) working from the position that HiTOP relies too much on analyses of traditional diagnoses, baking in limitations of the DSM, and that we need to move to symptom-level analyses to fix it

It turns out that rebuilding HiTOP from the ground up doesn’t change much 💀

Engagement-based #algorithms amplify intergroup hostility + moral-emotional content, leading it to be overrepresented in your feed

This leads us to falsely perceive that people want to see this kind of content and share more of it.

I built a DAG diagram with garden hoses for teaching.

In Madrid we face extraordinary cuts and losses in budget, my uni may be unable to pay workers in mid-term. This is caused by govt pushing privatization. Despite all of that we still fight for public, high-quality and autonomous education, making good research:

There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >
But here's, the thing, p values and significance become useless at such large sample sizes. When you're dividing the coefficient by the SE and the sample size is in the tens of thousands, EVERYTHING IS SIGNIFICANT. All you're testing is whether the coefficient is different than zero.

we have gone from a world in which we were told not to cite wikipedia because it was unreliable to a world where wikipedia might be the only reliable source left on the internet and we all owe a lot to the pedantic nerds who got us there
for all people mock it wikipedia is genuinely one of the wonders of the modern world

many ppl highlighting flaws in this article. but having fought in the "80% desistance" wars of the mid-2010s, I remember asking anti-trans activists if they'd be ok if 80% of youth were helped by gender-affirming care (flipping their argument). & they *never* answered. b/c they want *zero* trans ppl

After years of complaining about cancel culture, the current administration has taken it to a new and dangerous level by routinely threatening regulatory action against media companies unless they muzzle or fire reporters and commentators it doesn’t like.

A wide-ranging Nature News article on developments in peer review. Like we mentioned in our billion-dollar donation article (link.springer.com/article/10.1...), I think peer review should be opened up via more post-publication (preprinting) review and smaller checks, www.nature.com/articles/d41...

Tech fascism, like the tech libertarianism that birthed it, specializes in hijacking left-wing ideals, repackaging them as right-wing ideology, and selling the resulting sludge as “moderate/centrist/common sense.”

The roots of this go very deep. Keep an eye out!

🌲🧯Forest fires are increasing. Does climate change play a role?

The short answer? Yes, it does.

The hotter, drier conditions create the vicious "climate-fire feedback loop," leading to more devastating and frequent fires. Get the long answer👉 go.wri.org/climate-fire-loop-bs

Climate change is making forest fires worse, and vice-versa — creating a vicious "climate-fire feedback loop" that has helped fuel record burns in recent years.

A veces desde la psicología no podemos evitar mirar con cierta ternura a los economistas tradicionales, los del Homo economicus, la racionalidad y la maximización del beneficio.
Nosotros sabemos que el ser humano a veces toma decisiones irracionales, o es solidario, o cortoplacista...
No, Wikipedia no es una anomalía económica. El espacio de internet ha sido siempre para compartir de manera desinteresada, desde wikipedia hasta los foros. Es el capitalismo el que lo ha anegado con sus mierdas.

Aceptar este marco político es jugar con las cartas marcadas.
“Wikipedia is this economic anomaly. In many ways, it’s sort of magical that people will just volunteer without explicit economic incentives to create artifacts that are meant to share knowledge with everyone in the world”
