Brummie rated low IQ twang.
BRUMMIES should keep quiet if they want to avoid appearing stupid, a study suggests.
Experts found even people who stay silent are perceived as having a much higher IQ than those with the West Midlands accent.
The Yorkshire twang, seen as "wise and honest", was rated the most intelligent-sounding. It beat into second place the plummy tones of the "Queen's English" or Received Pronunciation.
Volunteers looked at photos of female models while listening to three accents: Yorkshire, Brummie and RP or silence, and rated them for IQ. The Brummie accent was last.
But Dr Lance Workman, who led the research at Bath Spa University, said Brummie had become a stereotype for low IQ. But he added: "There's no link between regional accent and intelligence."
Brummie BBC host Adrian Chiles said his accent helped him: "You only have to ask one decent question and they look at you like you're a genius."
