Gentle reminder that a correlation coefficient isn’t a particularly great way to quantify the effect of a dichotomous treatment. See also

Great paper with important implications for understanding life cycle inequalities. For example, one can see how strong memory of in labor market trajectories can lead to amplification of the experience of early career discrimination. Recommended!

New evidence that twin estimates of heritability should be adjusted downward by about half
So there you have it, twin study estimates were greatly inflated, and molecular data sets the record straight. I walk through possible counter-arguments, but ultimately the uncomfortable truth is that genes contribute to traits much less than we always thought.

@fabianpfeffer.bsky.social proved that he is not only an expert on inequality but also on precision craftsmanship by successfully tapping a keg at the Hofbräuhaus.
The crowd cheered as the first golden drops flowed, sealing what can only be described as his official Bavarian citizenship ceremony.

Remember, if you encounter what seems like an implausible survey finding, ask:
1. Were survey respondents selected randomly or was this an opt-in poll?
2. Could the results, especially for young adults, be driven by bogus respondents?
