  • Yeah but I’m pretty sure the relative wealth/affluence of the neighborhood you grew up in is significantly more strongly correlated with overall life outcomes

    That is, surprisingly, incorrect. A meta-analysis by Strenze (2007) showed that the predictive power of IQ is slightly stronger than that of parental socio-economic status (SES) (Table 1). Specifically, IQ measured before age 19 outdoes parental SES in predicting future educational attainment, occupational status, and income after age 29 (see “best studies” on Table 1). In other words, if you want to predict an adolescent’s success in adulthood along a given metric of success (e.g., income, educational attainment, or occupational status), it is more useful to know that adolescent’s IQ than to know the success of their parents along that same metric. In the conclusion of the analysis, Strenze (page 416) argues that this would be unexpected if the predictive power of IQ could be attributed primarily to its association with parental SES:

    Despite the modest conclusion, these results are important because they falsify a claim often made by the critics of the “testing movement”: that the positive relationship between intelligence and success is just the effect of parental SES or academic performance influencing them both (see Bowles & Gintis, 1976; Fischer et al., 1996; McClelland, 1973). If the correlation between intelligence and success was a mere byproduct of the causal effect of parental SES or academic performance, then parental SES and academic performance should have outcompeted intelligence as predictors of success; but this was clearly not so. These results confirm that intelligence is an independent causal force among the determinants of success; in other words, the fact that intelligent people are successful is not completely explainable by the fact that intelligent people have wealthy parents and are doing better at school.*

    The meta-analysis does find that parental SES also correlates significantly with the future outcomes of the child. However, because youth IQ and parental SES are correlated, it is possible that some unspecified portion of the predictive power of youth IQ is due to its correlation with parental SES (or vice-versa). To get a more precise estimate of the effects of youth IQ (independent of parental SES), we need to estimate the predictive power of IQ after controlling for parental SES.

    Success is undoubtedly multi-factorial. Who you know is important. So is parental educational achievement, access to nutritional food, an absence of violence in the home, IQ, etc.


  • Thanks for the study. I agree on all points. This is the challenge with sociological research: it is unethical to conduct controlled studies. We will never have controlled IQ research. The study suggests we continue to perform better quality primary research, and I fully agree. Until then, as per the data in the study, the correlative evidence remains compelling. At least as far as sociological research goes.

    I tend to think this research is more compelling and useful at the macro level. We should bear in mind that the correlative coefficient between IQ and income is only between 0.2 and 0.4. There are many other factors which also impact outcomes.








  • This is a super common and often unspoken phenomenon for fathers. It took me two years to feel emotionally attached to my first. Those two years sucked. It felt like all work, no reward. I powered through because love is a choice and I love my family. Slowly but surely, it happened. It happens for most of us. Especially as they start taking interests in the things we are interested in. You start seeing yourself in them - their looks and how they behave.

    I am 99% sure you’ll end up loving your kids. I have three now. Just power through. You’re FAR from alone. Ask me if you have any questions.






  • Lifting the minimum wage directly impacts the available income of the lowest income classes, who in turn spend most of their income on consumption, increasing domestic demand and thus also helping the economy.

    Only around 3.7% of German workers earn minimum wage. Increasing their wages a little won’t move the needle on the economy. I generally support a healthy minimum wage, but Germany’s economic issues are systemic, and require much broader solutions. Making the cost of doing business even higher right now in Germany - which is what raising the minimum wage does - is antithetical to fostering weak economic growth. Industrial production in particular continues to decline, which is a big problem for Germany. Merkel’s strategy of going all-in on Russian natural gas turned out to be catastrophic. The cost of energy is just too high now for a raft of different sectors. I’m sure you’ve heard all of this before in economic analysis, but these are some of the primary issues and tactical solutions Germany should tackle.

    1. Cheaper energy. This is strangling industries which employ millions and have been the backbone of the economy for decades. Germany needs to build nuclear capacity ASAP, or begin importing massive amounts of Russian natural gas, or begin burning a lot more coal. For environmental, economic, and ethical reasons, I support nuclear. Renewables are about 4x more expensive than nuclear after imputing costs like storage and grid architecture [1].

    2. Germany needs to embrace efficiency at a cultural level. In 2023, 51 % of all point-of-sale transactions were made using banknotes and coins. I cite this not because I think cash is a perfect analogue for efficiency, but to underscore the distrust so many Germans have in technology. Most government departments still use fax machines. Germany’s internet infrastructure is just terrible. There is an astounding lack of digitisation across both the public and private sectors. This aversion to efficiency becomes an increasingly heavy anchor around the neck of the nation as the rest of the world embraces new technologies to build and serve more products and services, faster.

    3. Germany needs a new strategic focus in the economy. Even with cheap energy, industrial production can and will be done cheaper in developing nations. Their car industry is clearly unable to pivot to EVs, and it’s going to completely miss automated driving. Using VW software is like going back to a Nokia flip phone. They need to figure out how to invest in and excel at services and software. This is almost impossible to mandate at a governmental level in a democratic nation. This one will be the toughest to turn around and for this reason, my long term prognosis for Germany is poor relative to many other European nations.

    4. Restructuring Germany’s immigration system to block low and no skilled immigrants, and greatly simplify immigration for high skilled immigrants. Research by the ifo Institute concludes that the 2015 immigration wave has widened the implicit long-term debt burden, i.e., including future pensions, by almost 10 percent of GDP. According to this, every admitted refugee costs the budget around 225 thousand euros over the course of her or his entire life. [2] This problem is getting worse every year. Germany’s immigration system is very difficult to navigate, and can be quite hostile for legal, qualified migrants.

    5. Compounding all of the above is a declining fertility rate. Few countries have solved this issue, meaning [highly skilled and qualified[ immigration is more important than ever. I don’t think we can rely on improving native fertility rates.

    When an economy is performing as poorly as Germany, economic stimulus is required. This means lower taxes and increased government spending. QE is not possible for those using the Euro so it might mean accepting higher levels of debt. This is a distinctly un-German proposition. The current government has secured the right to increase national debt but only in the context of Russian aggression. Debt by itself is bad, but if used prudently to stimulate the economy in the right direction, can be useful. I sadly do not trust the German government to invest it wisely. It’s much more likely to go towards manufacturing mortar rounds, and to pay for ever increasing social services.

    Dane here. While I love trains, they are a) more expensive than flying in almost every long distance scenario, and b) take much longer. We are trialling sleeping trains but reception is mixed and capacity limited. People don’t like to waste an extra 2-4 days of their vacation on travel. Especially if they’re paying more for that privilege. I should note that this isn’t an issue of imbalanced subsidies. The EU subsidises air travel (in many ways) to the tune of around €30–40 billion annually depending on what you include and what you consider to be a “subsidy.” Using similar criteria, rail is subsidised to the tune of €40–75 billion per year. So rail gets a lot more investment despite it serving 16% fewer travel kilometers per year in the EU than air travel.

    The thing is, if even we can’t make it cheaper and faster despite our relatively high population densities and high rail subsidies, I fear the case is much harder still in the U.S. My personal position is that trains are excellent commuter alternatives, and should be liberally built and subsidised in all dense cities. For longer travel, there is no substitute for airoplanes.
