An IQ test would suffice. However, intelligence is usually fairly
obvious.


And yet, even people of moderate intelligence can understand
bernoulli

The average IQ of US enlisted men tested during WW1 was that of a12
year old.

IQ isn't really age related. though it is true that capacity increases
with age, the measurement is usually like/like otherwise it's kind of
pointless. So it would be fairer to say that they had a sub-normal IQ
of say ,less than 85 than to say they had the IQ of a 12 year old.
It'd be a bit like comparing the horsepower of a modern airplane to
the horsepower of a airplane from 75 years ago. In general, airplanes
of 75 years ago had smaller engines, but you could b talking about a
mustang. IOW, you're not neccesarily comparing like with like.

OK I dug around and Alfred Binet’s intelligence, or IQ, test used on
enlisted men also included an assessment of mental age. I guess it
should have been "The average mental age of US enlisted men tested
during WW1 was that of a 12 year old".

That doesn't make a lot of sense either but ...


Well, it makes sense to me. Pretty much what I was trying to say
earlier.

The average IQ is computed by administering a test to a large and
representative sample of the population on which the test will ultimately be
used, and then assigning 100 (an average IQ score, by definition) to the
average raw score obtained by the sample cohort on the test. The scoring is
then further normalized to ensure that a constant deviation in IQ score
represents a constant percentile. Usually 15 is the width of an SD in IQ
points, such that 130 represents two standard deviations above the mean in
scoring, or the 98th percentile.

How was the average mental age of the US population computed? The
biggest sample ever measured at that time was of US enlisted men. Was
the mental age that of a 12 year old French child?

All pretty much the same, actually. Leaving aside minor abberations in
race and culture (and we don't want to start one of those arguments
here, believe me) The difference in 12 year olds who have had similar
levels of stimulation is negligable.
No doubt they had some sort of idea of what a 12 year old was capable of
at the time and used that as a yardstick.
Most likely the way the mental age was measured back then was some sort
of simple literacy/numeracy test.
Even today's SATs aren't a lot different from that kind of measurement.
SATs aren't an IQ measurement, though they would reflect an IQ, they'd
be heavily influenced by the education of the person taking the test,
wheras an IQ test should pretty much eliminate hat factor.
IOW IQ is a measuement of potential. An analogy might be that IQ is like
the cubic inches


To this day, most newspapers use an eight grade reading level as a
standard in order to make their papers accessible to as many as
possible.

Most tabloids use a fourth grade reading level as a standard for obvious
reasons.
