 Well, the gap between what is researched and what is published is much bigger than what the lay public might expect. So we do loads and loads of studies and only a portion of those, the ones that come out really pretty, are published. But what that means is that we end up with a scientific literature that is all the pretty stuff and none of the stuff that went wrong. And what's a problem with that is that we can't learn from the things that went wrong.
