Good Evidence? A 2013 Panel Discussion

A reader shared this with me (thanks MP), I was unaware that it was online. From 7 years ago …

Recording of a debate held at the Institute of Physics, 4th Feb 2013. Co-organised by Science Policy Research Unit, University of Sussex and the UCL’s department of Science & Technology Studies.

Policymakers often talk up the importance of evidence-based policy, with increasing calls for randomised controlled trials (RCTs) as the best way of testing whether particular interventions work. But finding and applying evidence in policy is anything but straightforard. Evidence alone rarely wins complex political arguments. Often this merely shifts the locus of debate to what counts as evidence.

Speakers: Roger Pielke Jr, Professor of Environmental Studies, University of Colorado at Boulder; Richard Horton, Editor of The Lancet; Georgina Mace, Professor of Biodiversity and Ecosystems, University College London; Jonathan Breckon, Alliance for Useful Evidence.

Chair: James Wilsdon, Professor in Science and Democracy, SPRU, University of Sussex.

Fealty Trumps Truth

contagious

The figure above shows published estimates of “R naught” (or R0) a measure of the contagiousness of coronavirus (from Liu et al. 2020, published 13 Feb). The figure shows that 13 different estimates of R0 were published during the month of January 2020, and these estimates ranged from ~2 to >6, indicating that coronavirus was highly contagious.

Thus, when Dr. Deborah Birx said today that “it wasn’t until the beginning of March that we could all fully see how contagious this virus was” she is either lying or revealing complete incompetence. Strong words, yes, but there is no other choice. Dr. Birx is a political appointee by Donald Trump and it appears that fealty trumps truth.

See the comments of Dr. Birx below.

Did the Trump Administration Delay the WHO Emergency Declaration?

CNBC-trump

Yesterday in the White House Rose Garden, President Trump announced that the U.S. government would be suspending payments to the World Health Organization. Among the president’s complaints was this: “The delays the WHO experienced in declaring a public health emergency caused valuable time, tremendous amounts of time.”

Here I take a look at this claim, and conclude that the United States government either contributed to the delay in the WHO emergency declaration or the US government outsourced its decision to the WHO to declare a domestic emergency declaration — which occurred only after the WHO eventually declared a global emergency.

Let’s look at the facts.

Eight Weeks Behind: Clarifying the Early U.S. Coronavirus Testing Failure

ayzozhoihjfxtnwq5ua33ljrli

Bottom line: It is normal for the US government to develop its own disease testing under CDC. Experts in CDC are typically very good at it. But in the case of coronavirus, the US government developed a flawed test, creating lengthy delays in testing and in parallel left obstacles in place that would have shortened the delay. Meanwhile, U.S. government officials have repeatedly misled the public and policy makers. In total, more than 8 weeks were lost due to policy failure. This post explains and documents this remarkable policy failure.

Covid-19 Resources for Research and Teaching

coronavirus-information

This set of resources related to Coronavirus and COVID-19 is focused on science advice and policy evaluation. It is intended to support my professional research and teaching, and if you find it useful, so much the better. It is the next iteration of an earlier syllabus, that became too unwieldy due to the amount of materials.
