Like so many aspects of this pandemic, we were told one thing and then the opposite by the ‘experts.’
I am not suggesting that ‘the experts’ are evil or ignorant, or that we should stop listening to them. The situation is evolving all the time, and new information should cause an ‘expert’ to reassess their recommendations. I genuinely believe that everybody is doing the best they can.
However, I think this is a good reminder that an ‘expert’ is human, like everyone you know. And humans make mistakes; they change their minds with new information, and both their decision-making process and the data by which they make decisions are never perfect. This is always the case, no matter how enlightened one becomes and whether we are in a pandemic or not.
