“Evidence can be a slippery word. It can range from robust research in a scientific journal to unsubstantiated PR fluff. Unless you can sort the good from the bad, the relevant from the irrelevant, you cannot know what information to trust. A central part of my job is to ask for evidence and ask questions of that evidence. I encourage others to do the same.”
