It's related to anti-discrimination / "psychology-test" laws. If there is any sort of "test" given as a condition of employment, it must be relevant, standardized, non-biased, reviewed by specialists and approved, etc.
The value and definition of "IQ" is widely disputed and generally seen as of limited relevance to the actual work and performance of that work (uncorrelated). Look it up and do some research if you're interested, this is just a quick showing of _why_ tests may be considered bad.
One day I wonder if some lawyer will strike it big by making an argument that looking at universities is discrimination because e.g. family connections and wealth give you a big leg up in getting into certain elite schools...
The linked image you shared is one I've seen before that was a Louisiana state voter literacy test used for voter suppression. It was disproportionately administered to black voters[1]
I'm not saying that IQ tests are useful measures of ability to do a job. I just wasn't aware there was actual law or precedent forbidding their use.

Wouldn't this disqualify a lot of whiteboard interviews too? Most startups don't have a standard question bank reviewed by experts or grade on a standard rubric.
The classic "how many gas stations are there in the USA?" type of interview question seem exactly like an IQ test and not at all relevant to job requirements.
