(a)The number of persons originally enlisted or inducted to serve on active duty (other than active duty for training) in any armed force during any fiscal year whose score on the Armed Forces Qualification Test is at or above the tenth percentile and below the thirty-first percentile may not exceed 20 percent of the total number of persons originally enlisted or inducted to serve on active duty (other than active duty for training) in such armed force during such fiscal year.
(b)A person who is not a high school graduate may not be accepted for enlistment in the armed forces unless the score of that person on the Armed Forces Qualification Test is at or above the thirty-first percentile; however, a person may not be denied enlistment in the armed forces solely because of his not having a high school diploma if his enlistment is needed to meet established strength requirements.
An AFQT score is derived from the ASVAB(essentially the militaries’ IQ test). IQ scores are based on a normal distribution of scores from the general population with a mean of 100 and a standard deviation of 15. So the 30th percentile represents an IQ score of 92 while the 10th percentile would correlate with an IQ of 81.
This is a myth. There IS a test, called the “Armed Services Vocational Aptitude Battery (ASVAB)”, which is a competency test to see what jobs you would be suited for, but that is NOT an IQ test.
Sure, if you score badly on that test you will LIKELY have a low score on an IQ test, probably because something like 40% of American adults are illiterate or have low-literacy and that would impact your ability to do any test.
But the military does not IQ test.
It is a percentile-based test against others who’ve tested on it. So it’s similar to an IQ test in that regard.
Sure… But it’s a DIFFERENT TEST, on a different population of people, with the goal of measuring military-specific factors.
This is essentially a semantics argument and doesn’t make this post a “myth.” The military aptitude tests are effectively an intelligence quotient, just not a standard “IQ test”
And if low iq folks are more likely to seek enlistment, the distribution could be significantly lower than iq/the population at large.
Yes, there is absolutely a sampling bias here
There are probably ways to correlate the military test with a standardized IQ test, and which point the military test might be a rough proxy for IQ. If that was the case, the 80 IQ rule might be roughly accurate.
I don’t know if that’s been done though. Just playing devil’s advocate.
I think there have been studies on the correlation between ASVAB scores and IQ scores. The correlation is supposedly 0.8.

Eh, I met plenty of very smart people while serving. I also met plenty of very fucking stupid people. I’d say the ratio is about the same as the general population, since the military offers a lot of very attractive financial incentives to poor and middle class folks alike. Although, free college is the number one reason most enlist, in my experience. I know it was the main reason I did it. Gotta love a society that allows colleges to price gouge tuition so badly in the first place…
Personally I agree that the military is as good of a sampling of intelligence as the general population, but there is something to be said about the potential issue of a normal distribution bias. (Up or down) If there was an analysis on it I’d wager that the correlation coefficient would be very close to 1. I just wish that the critics of this simplification would avoid portraying the ASVAB as having NO correlation with IQ.
People mention that there’s some dumb mfers in the military. My friend included.(I’ll let you decide on which side of that assessment he’s on lol) but I think it’s a familiarity bias. You’re forced to work with(and against) those individuals no matter your intelligence level in the military. In contrast, people in the general population tend to work mostly with people that are around their own level of intelligence unless it’s customer service.
Heh, never thought about this before, but that probably explains why both people in either customer service or the military tend to be jaded, cynical people, lol.
Different than what exactly? There isn’t one single IQ test.
