Because people who have English accents aren’t automatically smarter or more sophisticated than people with American accents, thank you very much.
The main significant effect found in this study was that people who’d lived at least three months outside the US rated the English accent significantly lower than people who’d only lived in the US. In fact, Americans who had not lived abroad considered the English-accented person to be much more intelligent than themselves, but the people who had lived abroad rated the standard American accent more intelligent than the standard English one. My preferred way of interpreting this (a bit tongue-in-cheek) is that Americans are happy to rate the English as more intelligent than themselves up until they actually start meeting and talking to the English.
And speaking English with a French accent doesn’t make you sexier or classier than someone who speaks English with, say, Chinese or Southeast Asian inflections. And so on.
