I identified one major error in a study on the Flynn Effect that I had frequently cited prior. It meta-anlyses performance on the number of digits one can memorise (digit span) forwards and backwards across time, finding that performance on forward digit span improved over time, but performance in backwards digit span worsened:| sebjenseb

Some policies and laws are better than others, but no system can consistently determine which policies are best and enforce them effectively.| sebjenseb

I started to suspect talent beat hard work when I started following esports again, most pros had more or less the same story: they got to a high rank (>98th percentile) after 6-24 months of playing and thought about going pro after they got good. If they started playing before the age of 16, they got better as they matured, and entered the highest rank by the time they were 20. Some players who took breaks, even long ones, could get to the top 200 of the ladder within a few weeks of playing. | sebjenseb
