Friday assorted links

1. SinoVac vaccine looking pretty good, and 300 million doses already sold (NYT).  And Pfizer-Biontech seems to work against the South African strain.

2. “Marginal-utility neglect.”

3. Covid in Zambia.

4. Alex redux: why do experiments make people uneasy?

5. Cocanha.

6. Sperm markets in Covid times, and disintermediation (NYT).  Recommended.  But a 1400 chess rating is nothing to boast about!

7. Angry people are more vulnerable to misinformation — Serenity Now!
