The pledge, for example includes this about corrections:
If we get any facts wrong, we will admit that promptly and publicly. We will post/publish/print/podcast/broadcast a correction or at least a clarification.

We will apologize and promise to be more careful next time. We will show a little humility.

We do not necessarily agree to abide by any particular code of journalism ethics or professional standards, although we may choose to do so. If we do, we will declare that publicly. If we don’t, we will declare that as well.
