Lessons from a year of Covid


Essay by Yuval Noah Harari in the Financial Times: “…The Covid year has exposed an even more important limitation of our scientific and technological power. Science cannot replace politics. When we come to decide on policy, we have to take into account many interests and values, and since there is no scientific way to determine which interests and values are more important, there is no scientific way to decide what we should do.

For example, when deciding whether to impose a lockdown, it is not sufficient to ask: “How many people will fall sick with Covid-19 if we don’t impose the lockdown?”. We should also ask: “How many people will experience depression if we do impose a lockdown? How many people will suffer from bad nutrition? How many will miss school or lose their job? How many will be battered or murdered by their spouses?”

Even if all our data is accurate and reliable, we should always ask: “What do we count? Who decides what to count? How do we evaluate the numbers against each other?” This is a political rather than scientific task. It is politicians who should balance the medical, economic and social considerations and come up with a comprehensive policy.

Similarly, engineers are creating new digital platforms that help us function in lockdown, and new surveillance tools that help us break the chains of infection. But digitalisation and surveillance jeopardise our privacy and open the way for the emergence of unprecedented totalitarian regimes. In 2020, mass surveillance has become both more legitimate and more common. Fighting the epidemic is important, but is it worth destroying our freedom in the process? It is the job of politicians rather than engineers to find the right balance between useful surveillance and dystopian nightmares.

Three basic rules can go a long way in protecting us from digital dictatorships, even in a time of plague. First, whenever you collect data on people — especially on what is happening inside their own bodies — this data should be used to help these people rather than to manipulate, control or harm them. My personal physician knows many extremely private things about me. I am OK with it, because I trust my physician to use this data for my benefit. My physician shouldn’t sell this data to any corporation or political party. It should be the same with any kind of “pandemic surveillance authority” we might establish….(More)”.
