During the build up to the referendum, Michael Gove warned of the prognostications of experts. He was pilloried for it because, after all, don’t we rely on the experts to inform us, advise us and generally teach us how we should behave? Should I take an umbrella? Is it the right time to buy, or should I keep renting? Should I invest in solar panels, or electric cars, or nuclear power? Is the planet warming or cooling, or both at the same time? Given that whenever the experts all agree it has proven wise to adopt a healthily sceptic stance, Gove’s much denigrated remarks were bang on the money.
