Users of Internet Explorer are less intelligent than those who use other browsers, according to a recent survey. AptiQuant, a "psychometric consulting" firm that provides hiring exams for businesses, gave online IQ tests to more than 100,000 people.
As you might expect those who used IE6 really were dumb although IE8 users performed slightly better on the test. There were little difference in the Iqs of Firefox, Chrome and Safari users, but apparently if you use IE with Chrome Frame, Camino or Opera you were more likely to have a higher IQ.
AptiQuant concluded that the study showed a substantial relationship between an individual's cognitive ability and their choice of web browser. Those with lower side of the IQ scale tend to resist a change/upgrade of their browsers.
