With COVID-19 spreading fast, people in power are having a hard time keeping up. Best to send for the experts.

If theres anything to be taken from the COVID-19 emergency, it might be that the world has re-discovered its faith in expertise, says Anne Glover president of Scotlands national academy, the Royal Society of Edinburgh, and a former chief scientific adviser at the European Commission. Its a great thing that people are turning to science; I would say there was always a very high level of trust in scientists, she told Science|Business.

Populism works by manipulating the emotions of a disaffected group of people. But this is not a great time to be blaming people. Instead, youre seeing individuals stepping up, she said.

Glover doesnt quite characterise events as the return of expertise. By and large, theres a lot of evidence that flows into policymaking all the time. But she says, there is at least a return of authoritative figures to the public eye.

In the UK, chief science adviser Patrick Vallance, chief medical officer Chris Whitty and deputy chief medical officer Jenny Harries have all done regular broadcast rounds for the past few weeks, earning praise for their calm and sober assessments.

The crisis cries out for a cooperative response, and youre largely seeing that among the four UK nations, Glover said. In Scotland, we have been seeing a lot of the chief medical officer and Jason Leitch [national clinical director for Scotlands National Health Service]. Both have clear voices and are honest about where the uncertainty lies this is comforting.

We dont want to hear our advisers adopting something like a line to take from policymakers, I would be very nervous if this was the case. Their value is providing evidence and being as straight as possible, said Glover who, from 2006 to 2011, was the chief scientific adviser for Scotland.

French president Emmanuel Macron has called coronavirus a war, but Its actually completely different to war time. Theres something out there we cant see and thats scary, Glover said.

But as long as we put science advice first and foremost and allow citizens full access to the thinking behind decisions, we will get through this. You have to tell people what youre doing but also why youre doing it, she said.

Infodemic

Yet despite the best efforts of science advisers, the feeling is that the UK governments recent handling of the crisis has created an overall confusing picture.

With information and disinformation flowing freely on social media, people are panic buying. Its astonishing I can hardly believe it, said Glover. This phenomenon points to a vacuum of credible information and this includes from scientists, politicians and the media. Without it, were seeing citizens take matters into their own hands.

Theres a huge amount of fake news on Twitter. Governments should be taking advantage of social media they do it during elections and guiding people towards good information sources, she said.

The UKs response to coronavirus has come in for widespread criticism recently after health secretary Matt Hancock distanced the government from the so-called herd immunity strategy that was discussed by chief scientific adviser Vallance last week. Hancock appeared to contradict Vallance, insisting, Herd immunity is not our goal or policy.

The herd immunity theory for COVID-19, which says that if a large number of people develop immunity to the virus, it will eventually stop spreading, has been widely contested. We probably dont know enough about coronavirus yet to talk about herd immunity. We dont know enough about re-infection rates. So herd immunity was a bit of a red herring, Glover said.

Following criticism of the UK government's communications, prime minister Boris Johnson, has begun to hold a daily press briefing. On Monday, Johnson said people in the UK should now stop "nonessential contact" and avoid pubs, clubs and cinemas to slow the spread of the coronavirus. Vallance said school closures could be introduced in the coming weeks (this policy has already been introduced in countries including Ireland and Belgium).

You need the highest level of discipline to have extremely tight communication coming out. Weve been lacking that a bit recently. Its a failure of the translation of advice, Glover said.

She backs calls by scientists to open up the models on which the government is relying to greater scrutiny.

All of us would welcome as much transparency as possible, she said. Opening up the models and their assumptions is a good step because we have a global community of scientists who work without animosity to get the best possible outcome for citizens, she said.

What would an EU science adviser do?

COVID-19 has demonstrated that expertise and institutions matter, but Glover is unsure what role an EU chief science adviser would play in the emergency.

In 2012, Glover became the first and so far only chief scientific adviser to the European Commission. She stepped down from the role in 2014 after incurring the wrath of green groups with her defence of the science behind genetically modified crops.

Many scientists were deeply unhappy when the previous European Commission president, Jean-Claude Juncker, scrapped the position, replacing it with seven scientists in a Scientific Advice Mechanism. The body has not spoken on COVID-19.

Had I been there, I would have been trying to work across all our networks. I would also have been communicating with the president as much as possible, Glover said.

Convening the worlds science advisers over videoconference is another step Glover would have considered. There is an existing network and I think its very powerful. Im very proud of setting it up, she said.

But overall, Glover says shes not sure the role would have been highly valued right now.

If I was there during this time, I dont know if there would be huge value in my announcements. Individual member states are dealing with things themselves and are not looking at Brussels; I wouldnt understand the local conditions in the member states either, she said.

So in some ways it could have been seen as grandstanding and not helpful; you dont want to add to the noise if it doesnt feel valuable, she said.

Glovers background is in molecular and cell biology, with her research exploring at a molecular level the way diseases like Alzheimer's and Parkinson's physically affect our bodies.

Shes optimistic well see a COVID-19 vaccine, but is less certain about when. You dont want to forgo trials. Youd need to also think about a strategy for delivering the vaccine the scale is so massive, she said.

In the meantime, she says well all have to get creative to stretch out our new, limited lifestyles.

I do believe were irrepressibly imaginative. Well have drinks with friends over Skype or via Facetime. My garden is going to get more attention than ever before too, said Glover.
