Reading the text of The Washington Post’s new guidelines for its staff’s use of Facebook, Twitter, and the like, I couldn’t help but think of…John Hughes. Almost every movie the director ever made revolves, in its way, around an axis of insecurity, its key characters so preoccupied with what other people think of them that they risk losing themselves in the angsty inertia of it all—until, by way of an hour or so of zany events, they come to realize that the most noble thing they can be is, of course, themselves.

To thine own self be true, et cetera. It’s a theme that’s not merely applicable to Sam in Sixteen Candles, or Cameron in Ferris Bueller’s Day Off, or the entire cast of The Breakfast Club; it’s also a tritely perennial moral in American culture, pop and otherwise: from Tom Sawyer to Tom DeLay, from The Sound of Music to Glee, our cultural artifacts continually emphasize the importance of being true to, you know, YOU. Yet the lesson’s persistence alone hints at the fact that we never seem to learn it completely: Try as we might to be true to ourselves, there are still all those other selves out there. And they have a pesky way of compromising all the you-ness, true-ness, etc.

And that—back to the Post memo—is especially so for journalists. Or, rather, for journalists employed by legacy media institutions, which have often imposed on their members a kind of fractured identity: person (complex, complete) on the one hand, and journalist on the other. Be true to yourself…but only to the extent that the self in question fits in with the ethos of the institution that employs the you. (This above all: to thine own brand be true.)

The Post guidelines, then—articulated with an imperious, high-school-principal-ed tone worthy of a Mr. Rooney or a Mr. Vernon—radiate the tension that will inevitably arise from an enforced disconnect between who you are and what you’re allowed to reveal about yourself. The unsigned document—summed up in a blog post, Friday night, by Post ombudsman Andy Alexander; obtained and published by Paid Content’s Stacy Kramer yesterday afternoon; and the subject of much debate, throughout the weekend, on (fittingly/ironically enough) Twitter—resonates with a journalistic, and yet still surprisingly Hughesian, style of insecurity. Which is to say, one grounded in that age-old adolescent tension: individuality on the one hand, popularity on the other.

And The Washington Post clearly has not seen The Breakfast Club. Ignoring the ‘Be True to You!’ moral, the memo suggests instead that the paper has prioritized popularity over authenticity. When using social networks, the memo warns, “nothing we do must call into question the impartiality of our news judgment.” Journalists at the Post “must refrain from writing, tweeting or posting anything—including photographs or video—that could be perceived as reflecting political, racial, sexist, religious or other bias or favoritism that could be used to tarnish our journalistic credibility.”

That’s fair enough, on the one hand: for journalists on a beat—reporters or editors—bias certainly won’t fly. And the guidelines in question are similar to ones already in place at the AP and The New York Times. But, still. There’s a difference, of course, between bias and opinion: ‘Bias’ suggests entrenchment, while ‘opinions’ can, you know, change. Journalistic credibility comes not from the ability to disguise one’s opinions—or, worse, from a journalist’s lack of any in the first place—but rather from an openness to adjusting those opinions when new information warrants. ‘Transparency is the new objectivity,’ the catch-phrase goes; and it is intellectual open-mindedness, more than anything else, that is the unifying quality of both of those principles.
