Terrific @scientificdiscovery.dev post on randomized controlled trials in @ourworldindata.org.
Including this important chart on the impact of pre-registration.
Magically, when people had to pre-register outcomes, many of the benefits disappeared.

Remember, if you encounter what seems like an implausible survey finding, ask:
1. Were survey respondents selected randomly or was this an opt-in poll?
2. Could the results, especially for young adults, be driven by bogus respondents?

To say that "the data show these vaccines fail" in regards to the mRNA plaform is unforgivable.
For those of you that don't remember - this is the data from a SINGLE dose. In December 2020. So good I cried in grateful tears.
