AptiQuant, an online psychometric testing company, released a study claiming that Internet Explorer users are the dumbest.

AptiQuant offered over 100,000 free online IQ tests.  It then plotted the results by the type of browsers the testers used.

The results were that Camino, Opera, and IE with Chrome Frame users had “exceptionally higher IQ levels.”  Chrome, Firefox, and Safari users had “just a teeny bit higher” than average IQ levels.

Meanwhile, Internet Explorer users had lowest IQ levels.

The results of the study aren’t that surprising and have nothing to do with the inherent nature of Internet Explorer. Instead, it has everything to do with the correlation between tech-savviness and IQ. 

Tech-savvy individuals are more likely to upgrade and change their software, including their Internet browsers.  

Ten years ago, Internet Explorer owned an overwhelming majority of the browser market share. Since then, browsers like the Google Chrome, Firefox, and Opera have emerged as alternatives.

Internet users who switched/upgraded to these Internet Explorer alternatives tend to be more tech-savvy than the average Internet population. Even within different version of Internet Explorer, the users who had more upgraded versions were more intelligent than users who had old versions.

“From the test results, it is a clear indication that individuals on the lower side of the IQ scale tend to resist a change/upgrade of their browsers. This hypothesis can be extended to any software in general, however more research is needed for that,” stated AptiQuant.
