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 💀

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.

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.

Hanson believes the problem is not open access & APCs per se, but for-profit publishers that seek to publish as many papers as possible... the strain on academic publishing could be substantially alleviated if funding agencies stipulated... work they support must be published in non-profit journals.
