Random Thoughts

Our natural state is ignorance. We can only learn from data, and as the data comes in, our state of  knowledge and best practices change. But, partly because people think of experts as oracles, as opposed to experimenters and exploiters of trial and error, there is a presumption that either the experts know what is the best policy from the get-go, or else they are incompetent and ought to be replaced. That's opposed to what we know to be the correct situation in science----namely, no one knows anything, and you have to learn.
