LONDON

NO sooner had her words been reported in the British newspapers than she frantically took them back, saying that she had been misunderstood and misquoted. But the question remains: was Gwyneth Paltrow on to something when she noted (or didn’t) that “the British are much more intelligent and civilized than the Americans,” and that “people here don’t talk about work and money; they talk about interesting things at dinner”?

Whether Britons are objectively cleverer and more amusing than Americans, or whether they just sound that way, is one of the deep mysteries of British life for expatriates like Ms. Paltrow, who lives in London with her husband, the British rock star Chris Martin, and their children, Apple and Moses.

Britons seem to have the advantage of accent: their exotic pronunciation can make even dubious observation sound like unimpeachable truth. They are also experts at the art of speaking coherently and with authority on topics they know little or nothing about. “Every Englishman can talk for 15 minutes on any subject without a note,” Norman Mailer has been quoted as saying.

This somehow makes them seem more persuasive. When Tony Blair put the case for the Iraq war to Congress in 2003, his elegant fluency made him appear not only more articulate and intelligent, but also more credible, than President Bush. If silky-tongued Mr. Blair supports the war, some Americans felt at the time, then there must be something to it.
