<< Part of the answer is that The Economist is maintaining a historical tradition that other publications have abandoned. ... Historically, many publications printed articles without bylines or under pseudonyms—a subject worthy of a forthcoming explainer of its own—to give individual writers the freedom to assume different voices and to enable early newspapers to give the impression that their editorial teams were larger than they really were. The first few issues of The Economist were, in fact, written almost entirely by James Wilson, the founding editor, though he wrote in the first-person plural.
But having started off as a way for one person to give the impression of being many, anonymity has since come to serve the opposite function at The Economist: it allows many writers to speak with a collective voice. Leaders are discussed and debated each week in meetings that are open to all members of the editorial staff. Journalists often co-operate on articles. And some articles are heavily edited. Accordingly, articles are often the work of The Economist's hive mind, rather than of a single author. The main reason for anonymity, however, is a belief that what is written is more important than who writes it. >>
