PC World reports that a "psychometric consulting" firm called AptiQuant gave free online IQ tests to 100,000 people, and then plotted the scores against the browser on which the tests were taken.
It found that Internet Explorer users scored lower than average, while Chrome, Firefox and Safari users were very slightly above average. Camino, Opera and Internet Explorer with Chrome Frame were scored "exceptionally" high.
I have a feeling that this is nothing more than a marketing gimmick but is there any validity in in the study? Is there any independant data to back this up or refute? Can a anyone who takes and online IQ test really be allowed to score Exceptional?
