The epidemiologist who advised on Ebola and Covid discusses the value of evidence in light of AI and social media, and how the notion of fact has long been divisive
Adam Kucharski is a professor at the London School of Hygiene & Tropical Medicine. As a mathematician and epidemiologist, he has advised multiple governments on outbreaks such as Ebola and Covid. In his new book Proof: The Uncertain Science of Certainty, he examines how we can appraise evidence in our search for the truth.
What inspired you to investigate the concept of proof?
Alice Stewart, an influential epidemiologist, used this nice phrase that “truth is the daughter of time”. But in many situations, whether you’re accused of a crime or thinking about a climate crisis, you don’t want to wait; there’s an urgency to accumulate evidence and set a bar for action. We’re entering an era where questions around information – what we trust and how we act – are increasingly important, and our concepts of what we can prove are shifting as well.
