YOUR taste in music reflects your intelligence - and Beyonce fans are among the most stupid, it was claimed today. Devotees of the Destiny's Child star came close to the bottom of the pile in a student's comparison between exam results and musical tastes.
But they are not the worst of the worst - unless they are also fans of rapper Lil' Wayne - because his followers are deemed the least intelligent.
Devotees of Justin Timberlake and Jay-Z also ranked low in the scale, it was claimed.
They are among the findings of the probe by Virgil Griffiths, a PhD student in America, who puts Beethoven listeners as far and away the smartest.
Griffith compared students' scores in SAT exams with their favourite music acts and genres by analysing data on social networking sites.
Those who prefer Indie music are most intelligent, while gospel, pop and rock fans were all ranked at the lower end of the scale.
Fans of legendary acts like Queen, The Beatles, Jimi Hendrix, Frank Sinatra and Bob Marley are all around average and above when it comes to brains, according to Griffith's graph.
And Radiohead, U2 and Bob Dylan count some of the more intelligent people among their fans.
Those who are mad about pop music did not fare well in the analysis.
As well as Beyonce, fans of Justin Timberlake and Jay-Z both ranked at the bottom of the scale.
Their supporters all got below 1,000 in SAT scores, with the average being a mark of 1071 out of 1600. Fans of composer Beethoven were way ahead of the rest with a score of more than 1300.
British bands Coldplay, Muse and Oasis all came in dead central in the "Music that makes you dumb" graph.
On his website, of the same name, Griffith describes the results of his study as "hilarity incarnate".
He introduces the test by saying: "I've listened to artists who after listening to I thought to myself 'Wow... loving this rubbish says a lot about someone and how much they got going on in their head'.
