Every single day, you take several IQ tests. You just aren't aware of them.
Did you look both ways before crossing the street? Did you get a flu shot? Did you buy that $4 organic banana? These are all IQ tests, and the result is either pass/fail. Occasionally, flunking one of these daily IQ tests has very real consequences.
The CDC reports that, in August 2016, at least 17 people in Colorado flunked an IQ test when they consumed raw milk and became sick. Milk samples and patient samples both tested positive for antibiotic-resistant Campylobacter jejuni, which causes vomiting and diarrhea.
