You make this sound like someone with an IQ less than 120 is mentally impaired.

An IQ of 100 is defined as the median IQ level for a population. The range between 90 and 130 covers the whole gamut of human intelligence that's commonly considered normal.

Much of the day-to-day work in IT often doesn't need original thinking but merely skillful application of known methods and patterns, which in turn doesn't require a college education.

Find one successful programmer at Google/Apple/Facebook/Cisco/etc. with an IQ of 90. Remembering basic equations, keeping long sequences of functions sorted in your head, even understanding FTP/Git/CL instructions require this level cognitive ability. When you deal with people who can't hang shirts you'll start to understand this. There are just under 200 million Americans with IQs between "can't hang shirts" and "productive programmer."

Point proven, eh? I'm not talking about these people (though I surmise there are quite a few in these companies as well who don't have that level of intelligence and simply tag along ...) but about the vast majority of IT workers working on some supposedly 'boring' database application.

Google and Apple in particular have been known for hiring highly qualified engineers only to then have them maintain some run-of-the-mill administrative software they're vastly overqualified to work on.
