A few things:
1. Latent academic achievement test results and latent IQ test results correlate at about r = 1
2. Latent g correlates with achievement tests at r = 0.74 on average
3. Even if we use GPAs, the correlation reaches a pretty high r = 0.55.

Sensory input suppresses internal signals.
That's why binge-watching feels better than sitting with yourself when you're depressed.
For those who feel their purpose is missing, first check whether you're muting it.

The fact that literacy rates are inversely correlated with the strength of teachers' unions tells you everything you need to know about the goals and priorities of teachers' unions.

Tärkeä muistutus PISA-keskusteluun: PISA-testi on käytännössä älykkyystesti. Psykometrisesti mitattu ÄO korreloi todella voimakkaasti PISA-tulosten kanssa! Kuvasta puuttuvat maat joilta ei ole sekä PISA-tuloksia että tarkkaa ÄO-tietoa saatavilla👇
Here is PISA 2025 vs measured IQ. r = +0.79, n = 59
I used Becker’s psychometric column because Lynn used school tests for most IQ estimates, so it partly measures itself.
2+ IQ samples only.
31 PISA countries have no measured IQ or a native PISA score.

This study of the Dunedin cohort in N. Zealand finds most adults classified as having ADHD did not have ADHD in childhood and there is no genetic overlap either. psychiatryonline.org/doi/10.…

I win again!
Newly-released Swedish data shows that the rise in autism between 2001 and 2020 was...
ENTIRELY attributable to an increase in cases WITHOUT intellectual disability—less severe cases than used to be the norm!
The autism epidemic is not real: we just diagnose more.

Jos joku vielä ihmettelee miksi luottamus yliopistoihin rapisee: Psykologian professoreista reippaasti yli puolet (54,7%) on valmiita valehtelemaan tutkimustuloksista edistääkseen omia poliittisia tavoitteitaan 🤯

"Myös samankaltaista työtä tekevien välillä pitää voida olla palkkaeroja, jotta työntekijöiden väliset erot osaamisessa ja ahkeruudessa voidaan huomioida" (%)

KOK 89 %

Pitäisiköhän peruskoulussakin antaa kaikille samat arvosanat osaamisesta riippumatta?

Expert performance is not the product of talent.
It is the product of deliberate practice.

Teenagers are spending as much time on social media as they would for a full-time job.
Girls are spending more than 35 hours a week on social media and boys are not far behind. If they keep this up, it means the average teenager will spend more than 10 years of their life doomscrolling.
This is why research on this topic is crucial. We still know very little about the long-term effects of this kind of exposure (most studies on the causal effects of social media are limited to a few weeks). oecd.org/en/publications/gro…

Päivän Hesarista. Jos omasta HS-kuplasta poikkeavien ajatusten kuuleminen saa aikaan tarpeen huutaa niin ehkä pitää pohtia uudelleen onko todella niin avarakatseinen ja suvaitsevainen kuin on itselleen uskotellut.

Women in finland are more supportive the rape-facilitating policy of mass immigration.
A well-known but weird phenomenon.
My best guess about the reason is that women are more susceptible to social pressure and to mainstream propaganda. And that these factors are stronger than even their antipathy against rape.
