Our favourite communicator of risk talks about the statistics of COVID-19, the quality of government briefings, and how to counter misinformation.

Why a positive test result doesn't necessarily mean you have the disease.
It would be foolish to ignore evidence. Luckily Bayes' theorem shows us how to take it in into account.
The company 23andMe made headlines by launching its DNA testing service in the UK. But how are the risks of developing a disease calculated?
Florence Nightingale died a hundred years ago, in August 1910. She survives in our imaginations as an inspired nurse, who cared passionately for injured and dying soldiers during the Crimean war, and then radically reformed professional nursing as a result of the horrors she witnessed. But the "lady with the lamp" was also a pioneering and passionate statistician. She understood the influential role of statistics and used them to support her convictions.
