I say the Reg conducts a study to prove/debunk this bit of folk wisdom.
Then conduct a survey of journalists who use IE.
Thus proving that IE users are as dumb as a bag of hammers, and journalists are as dumb as a bag of IE users.
Additionally, add an inverted intelligence scale of sorts to the official Reg unit system. Stupidity measured in bags of hammers. (Smaller units can be boxes of rocks or IE users.)
1 bag of hammers=6 boxes of rocks=93 IE users (just for the purposes of example.) Or something along these lines. The higher the IQ, the less IE users.
