Opera users have the highest IQ
Consulting company AptiQuant Psychometric Consulting has published a comparative study (PDF) on differences in the coefficient of intelligence of users of different browsers. Of course, this is absolutely crazy idea - to compare IQ depending on the browser, but what can’t you do for the sake of PR of your services.
One way or another, but the results of the study were truly amazing. It turned out that the highest intelligence is among users of the rare Opera browser. Moreover, their IQ is growing over time , no matter how scary it sounds.

While for Opera users, the IQ is over 125 points, for Internet Explorer users, intelligence is registered below average, around 80.
Between 2006 and 2011, IE's user intelligence dropped significantly. Probably all more or less smart people switched to alternative browsers. Over the same period, the intelligence of Opera users has grown from 100 to 125+.
The following graph shows the distribution of users with different IQ across different browsers. On a vertical scale, the share of this browser in the sample of users with a certain IQ level. For example, if you look at the green line (Firefox), you can see that among people with low IQ (on the left), its share is small, and among people with the highest IQ (on the right), it is the undisputed leader. In the group of people with minimal intelligence, IE is the undisputed market leader.

Data obtained from the results of online IQ tests in 101 326 users over 16 years of age. Wechsler Adult Intelligence Scale (IV) was used as a test, the error is standard 15 points. Canadian company AptiQuant Psychometric Consulting specializes in psychometric testing.
