Part of what makes science different is that it corrects itself—or, at least, ought to be correcting itself. That process doesn’t always work as smoothly as it should, but it does happen. Retraction Watch is a blog that takes you inside the scientific community to see that process in action as published papers are withdrawn for errors or fraud, and science polices itself via the drive to find the truth. If you’ve ever wondered how this works, or whether scientists ever really catch the fibbers and fail-ers, check it out. What goes on in the scientific world outside of the lens of the media is a fascinating thing.
