This year I decided to read + rate all the Shakespeare plays (don't tell my HS teachers but I had never read/seen a Shakespeare before!). After just finishing (read in semi-random order), here are the results~
My highest rated plays were Hamlet and Antony and Cleopatra, both of which were perfect 10s. The lowest-rated was Pericles, a 1. Overall, his plays improved in score with year, and comedies and tragedies were higher-rated than histories.

The complexity of group interactions seems to overrule the consistency of individual behavior to create group-level developmental patterns that are highly unpredictable over longer timescales.

🐟🚨 Fish paper alert! 🚨🐟 You might already know that individuals are unique, even when they’re genetically identical clones raised in identical environments. But what about groups? Groups of clones are distinct from birth, but (unlike individuals) those differences do not predict later behavior!

I would still completely reject the social, political and economic conclusions that hereditarians draw. There is no reason for us to structure our society and ethics in ways that reinforce supposed biological inequalities, rather than in ways which ignore or even mitigate them.

In 2023, @nature.com published 'Papers and patents are becoming less disruptive over time', receiving world-wide media attention. Our Matters Arising, published after a 32 month delay (more on that soon), shows that the reported decline can largely be attributed to dataset artefacts. 🧵

New meta by @peterhaehner.bsky.social et al (I'm a little middle author) on individual differences in personality change across the lifespan (229 studies, N = 230k) 10.1037/bul0000525 Cool finding (imo): For all Big Five, variance in change is greatest in youth, declining through young adulthood!
Individual differences in change for each of the Big Five across ages 0 to 80. The trend for each trait is that individual differences in change are decreasing with age.
