Free Online Psychometric Tests

Psychometric testing firm says dumb people use Internet Explorer ...

According to a new report, dumb people are more likely to use Internet Explorer than smart people. It’s a finding so apparently defamatory that the company responsible for the statement is allegedly being threatened with a lawsuit by inflamed Internet Explorer aficionados.

Online psychometric testing company AptiQuant, based out of Canada, turned its analytical skills to a group of more than 100,000 individuals in an effort to determine the IQ scores associated with various Web browser users. Over a period of around four weeks, the company gave a Wechsler Adult Intelligence Scale (WAIS) to users looking for free online IQ assessment tests, then recorded the results and browsers used for all participants above the age of 16.

Across the board, the average IQ scores presented for users of Internet Explorer versions 6 through 9 were all lower than the IQ scores recorded for Firefox, Chrome, Safari, Camino, and Opera users.

Humorously enough, those using Internet Explorer with the Chrome frame built-in actually ranked third in IQ scores among this browser list. Opera users reported the highest average IQ score – hovering around the 120 to 130 range, which is a bit higher than the WAIS test’s population mean of 100 (and standard deviation of 15).

AptiQuant’s report notes that the only statistically significant difference in IQ scores occurred between Internet Explorer users and their counterparts. There was not a significant difference in IQ scores between non-IE browser users, even though these users, in aggregate, reported a higher average IQ score than IE users…

“I just want to make it clear that the report released by my company did not suggest that if you use IE that means you have a low IQ, but what it really says is that if you have a low IQ then there are high chances that you use Internet Explorer,” said CEO Leonard Howard.

Uh, OK.
