2/ We developed scales to measure saving disposition (tendency to save) and financial distress (struggling to make ends meet), by factor-analysing self-reported data of adult twins in Minnesota and Colorado.

This particular ethnic cleansing does not fit the narrative of American elites, so there will be no moral outrage. Most Westerners don't even know it is happening.

Disgusting to see a Trail of Tears in the 21st century & on the 100th anniversary of the 1923 expulsion of the native minorities of Turkey (including my grandparents). We shouldn’t tolerate anymore nations occupying land, if they don’t at a minimum want the people who live on it.

4/4 Controlling for SES, distance between parents’ and offspring homes, and area political composition did not alter the association. Of note is that spousal correlation for political opinion was 0.80

@andrei_mntn We invented academia, what did you expect? :P More seriously, GR has a culture of expecting everyone to enter tertiary education, and of disdain for vocational training. A similar pattern exists in S. Korea, and is related to the demographic collapse of both counties.

Our paper on associations between parents’ genes and parenting is now out! We studied these associations in >30k parents in the UK, US and New Zealand, adopting a life-course approach to parenting: 1/n

@DamienMorris @TedsProject @robkhenderson I would expect that offspring of two-parent households are overrepresented in TEDS compared to the UK general population.

New paper out with colleagues! In a unique sample of biological and adoptive families, we find a consistent parent-to-offspring transmission of educational attainment, which is partially mediated by mother expectations and family income. Congrats, Elise!

4/ Clark proceeds to say that the salient finding of his research is the inefficiency of social interventions. This subject is also explored in Harden’s book “The Genetic Lottery”. Harden quotes: "the large majority of interventions produced weak or no positive effects”.

3/4 The parental effect on politics is unlikely to be a sampling artifact. In the same sample, IQ followed the usual pattern of high h^2 and no parental influence.

@_alice_evans @JoHenrich @JF_Schulz I was really shocked to discover that some American families *make their children pay rent* when they live with them past age 18

Alright then, 1. Waiter 2. Barista/coffeemaker 3. High school teacher (as intern, not sure if it counts) 4. Bank agent / debt collection (not proud) 5. Soldier/paratrooper (is that even a job? I did get paid) The ones I would tag have been challenged already

@SashaGusevPosts This seems more realistic. Adoption and extended family designs show little to no vertical cultural transmission.

7/ The usual sources of bias in twin studies (assortative mating, gene-environment correlation) apply here. And of course, our sample can be considered representative only of "Middle America" and the findings may not generalise to other populations.

5/ The within-family association persists after controlling for income, intelligence, and personality traits. In our sample, saving disposition was a better predictor of financial distress compared to income or intelligence.

2/ In describing the study, Clark tacitly admits that his model does not necessarily prove genetic causation.
