The natural experiment of the Finnish comprehensive school reform 1972—77 suggests that less tracked curriculum leads to stronger genetic prediction of education among men and those from low-educated families.

No, nyt on sosiologiaa potenssiin kaksi!

@HaLahtin & al. käyttivät peruskoulu-uudistusta luonnollisena koeasetelmana ja selvittivät koulutuksen geneettisten riskipisteiden ennustevoimaa. Tuloksena syntyi lisäevidenssiä peruskoulu-uudistuksen puolesta.

Back to roots! It is already five years since 2019 when I defended my dissertation. And oh, what has happened in the meanwhile! Nice to revisit the electoral participation research again. And the journal @ElectoralStdies is the one, where my publishing career first began in 2016.

[Helsinki Institute Demography & Population Health @PRUhelsinkiuni]

It is not the time from the cradle, but the time to the grave, that counts.

A study published today in @ElectoralStdies offers a novel perspective on what explains the negative association between age and voter turnout among older electorate.

Vrt. eduskuntavaaleissa ero 80-luvulta eteenpäin tasaisesti pari prosenttyksikköä naisille. Sen sijaan viime presidentivaaleissa ero samaa luokkaa kuin tässä. Presidentinvaalit näyttävät jostain syystä kiinnostavan nimenomaan naisäänestäjiä.

[Hannu Lahtinen @HaLahtin]

Nosto #presidentinvaalit I kierrokselta: miesten kotimaan äänestysaktiivisuus oli 72,5%; naisten 77,3%. Huomattava ero, kiinnostavasti naisehdokkaat menestyvät valjusti.

In our new study in the International Journal of Obesity, we found that polygenic prediction of BMI is consistently stronger in the less advantaged socioeconomic groups! https://t.co/6RYXkk4x1a

A very good summary of our recent article. Thanks @lymanstoneky !

Using PGI for education AND mulitgenerational data, researchers use two complementing methods to explore how genetics influence education. https://t.co/oQrZHPwq3Y

@Nonissimo Tovi jo vierähtänyt, mutta eikös Netta Mäki tehnyt tästä aikoinaan väitöskirjan? https://t.co/BgjxkOXcfi

✨️ Interestingly enough (besides having worked as a lecturer of demography & in population research unit for years), this is my first publication in a demographical journal.

[Helsinki Institute Demography & Population Health @PRUhelsinkiuni]

A new study in @ReadDemography by @HaLahtin, @kaarinako, Pekka Martikainen and @bristimtom explores cohort changes in polygenic prediction of education in Finland, and to what extent it explains the recent increase in intergen. correlation of education https://t.co/XpiktbsCxo

[Demography Journal @ReadDemography]

Posted: “Polygenic Prediction of Education.” @HaLahtin @kaarinako Pekka Martikainen & @bristimtom examine the intergenerational transmission of education & how genetic knowledge can be used in sociological contexts. @PRUhelsinkiuni @MPDRnews @UCLSocRes

A remarkable demographic milestone just ahead!

[Birth Gauge @BirthGauge]

In 2022, the TFR of the World was around 2.23 children per woman. This was still slightly above the global replacement level of 2.18. Humanity will likely drop below replacement level this or next year.

I've asked an AI to generate a trailer for a HEIDI movie and now I can never sleep again

[Sasha Gusev @SashaGusevPosts]

I see this claim regarding the inherent "underestimation" of SNP-h2 often, so it's worth talking about it more concretely and looking at some real data.

[Hannu Lahtinen @HaLahtin]

A relevant reminder. Downward social mobility, altough a more delicate topic than upward and much less discussed, serves an important societal function.

[Hannu Lahtinen @HaLahtin]

Happy to have been able to play a small role in this new study!

[Helsinki Institute Demography & Population Health @PRUhelsinkiuni]

A within-sibship Mendelian randomization study in @IntJEpidemiol featuring PRU members @HaLahtin, Pekka Martikainen and Karri Silventoinen, suggests beneficial effects of education on health and mortality https://t.co/8ID25DzyZF

Few things offer a sharper moral choice than social media. Everyone knows that angry posts are most likely to go viral. So you can either go for reach by posting angrily (a la Fox News or the Guardian), or be thoughtful and get less.
