Hey, just a quiet reminder: it’s not true that people get more conservative as they age. *Populations* get more conservative as they age because poor and marginalized people die sooner.

Seniors Are More Conservative Because the Poor Die Off
Sometimes older voters aren’t just naturally more conservative. It’s just that wealthier and whiter people tend to live longer and healthier lives.

I love two stage tests: Overhearing the stuff students are organically discussing as they work collaboratively to get everyone a 100% on the 2nd stage of a two-stage coding-based exam so so so thoroughly dismisses any concerns I have with it taking up too much class time or not boosting learning.
