Letters: The dangers of certainty

Uncertain times

Sir: Kate Andrews’s article on the era of economic certainty (‘Crash test’, 18 March) is not the first article I have read – especially in the financial press – telling us that we live in uncertain times, as though at some stage in the past everyone knew exactly what was going to happen. I am unable to recall such a time.

I would argue that what we really should worry about is certainty. When people start talking about the end of history, claiming that there is a certain fortune to be made in buying cryptocurrencies or when ‘everybody’ knows the most important thing is to achieve net zero, that is the time to be worried. ‘Why did we not see it coming?’ the late Queen is reported to have asked about the 2008 banking crisis. Here is a simple answer: because no one can predict the future. The same is true of scientists, as we should have learned in the case of Covid.
