    1. Hilda Bastian, PhD. (2021, February 6). Unofficial unnamed AstraZeneca insider says they are doing the interim analysis for the US trial of the Oxford vaccine. AstraZeneca spokesperson says 4-6 weeks till data release. Https://t.co/VUHgbHN02d One is wrong? Or they’ll release only when have FDA minimum follow-up?

    1. Carl T. Bergstrom. (2021, January 31). A somewhat technical thread about measuring vaccine efficacy. We’re used to the notion that certain properties of tests for disease depend on prevalence: Positive and negative predictive value do, for example, whereas sensitivity and specificity do not.

    1. Carl T. Bergstrom. (2020, December 5). I don’t have a background in medical ethics but this makes me uncomfortable unless it was very clearly explained to study participants at enrollment, and to some degree even then.

    1. In one study, Lyubomirsky posted online two nearly identical requests for study participants. The only difference? One version told participants the study was meant to increase their happiness, while the other simply told them they’d take part in a cognitive exercise. After performing the same happiness-inducing activities, the people who signed up for the happiness study—the group Lyubomirsky saw as more “motivated” to become happier—gained more from the study than those who signed up for the other exercise.

      The study. This sounds very similar to the placebo effect, so I wonder if they have checked to see what effects they would find if they picked activities previously classified as neutral.
