Always are, always have been. For example, take any given set of measures for a construct, translate/backtranslate into another language, and you will often find that they have different meaning.
For years I had an office next to the most notorious researcher in the country (perhaps the world) on IQ differences across racial groups (who later went on to state that men were smarter than women on these same tests).
When discussing the statistical properties of an exam, one may hear the term “error” or measurement error used by psychometricians. Error can be considered information contributing to a person’s exam score beyond the person’s true or actual ability. So from computational and classical test theory perspective, error is
E = O – T or Error = Observed – True
more fundamentally: Xo= Xt + Xs + Xr
The Observed score (Xo) is the actual score on the exam and True score (Xt) is the person’s actual ability. Error is the difference between observed and true scores.
Error can be random (Xr) or systematic (Xs). Random error typically occurs during one administration. This may include guessing, misreading a question or a candidate not feeling well. In this instance of random error, the error would not likely occur during a subsequent administration. Systematic errors are typical attributes of the person or the exam that would occur across administrations. These errors typically do not have much to do with the content being measured. An example could be an exhaustive item with excess verbiage that asks a simple math problem and the simple math problem is what is intended to be measured, not the candidate’s ability to sort through the verbiage.

You're making a strawman argument that has nothing to do with the conversation.
I never made the claim that IQ tests are perfectly accurate, nor the claim that they perfectly encapsulate cognitive differences.

How do you know that the test items have construct validity (i.e., that they measure what they are supposed to measure, and nothing else, and do so with a high degree of reliability across situations and contexts)? How do you know that the groups in questions have equal levels of literacy?

You're jumping down the racial hole, as I said looking at group averages is stupid as different subsets of the same "racial" grouping will have very different IQs.

And when did I contredict this. I specifically stated that grouping together by race is beyond stupid.

No shit.

This good old fashioned "this information is forbidden, because I say so" argument.
I'm autistic you can kiss my ass if you thing I'm gonna casually accept that this information should be in the hands of the elite.
You're not a member of the cognitively disadvantages so don't dare tell me that I don't have a right to this information.
If the implications of keeping this knowledged subdued isn't obvious maybe you aren't near as smart as you think you are.
