Are You Trying to Prevent Your Developers From Making Mistakes?

The idea of if you think you can't be wrong at all then that's going to be a problem. And there's two different varieties I'm running into and one is the case of a manager who's trying to prevent her developers from making mistakes. That prevents learning and so that they get the experience of being told what to do but not the value of finding out what their original ideas would have yielded in the future. The thing that might help listeners to understand why we're saying being wrong is a good idea is to distinguish sort of how wrong.
