This pandemic demonstrates the importance of science advice for decision makers. @SenWhitehouse is right, an effective way to get science policy right is to consult scientists. Thank you for sharing @AliNouriPhD's article on how FAS is creating advisory councils to do just that!
We need science to tell us how #COVID19 spreads, who is most at risk, how to protect ourselves, and ultimately how to eradicate it. That requires the White House and Congress to actually… consult scientists. blogs.scientificamerican.com…
