David Hazinski, the sort of academic who gives intellectual snobs a bad name, wrote (with emphasis added on this blog):
But unlike those other professions, journalism — at least in the United States — has never adopted uniform self-regulating standards. There are commonly accepted ethical principals — two source confirmation of controversial information or the balanced reporting of both sides of a story, for example, but adhering to the principals is voluntary. There is no licensing, testing, mandatory education or boards of review. Most other professions do a poor job of self-regulation, but at least they have mechanisms to regulate themselves. Journalists do not.That should be “principles,” not “principals.”
Discussions of standards are more impressive when you can spell.
