I still do not understand why we are wasting scientific resources trying to stack rank humans on arbitrarily defined concepts like cognitive ability or intelligence.

After over a century of psychometric research in cognitive abilities and intelligence, what do we have to show for it? Whose life has actually improved for the better? Have the benefits from such research, if any, outweighed the amount of harm that has already been caused?

"arbitrarily defined concepts like cognitive ability or intelligence" correlate very well with objective metrics like educational attainment and income.

>the amount of harm that has already been caused?

Like what?

So is the goal to predict someone’s future income? Or to inform someone of how much money they supposedly should be making based on their test results and the supposed correlation between test results and income? Surely the test results aren’t being used anywhere to actually determine people’s income.

The goal is to predict if, for example, someone is better suited to sweeping the floors vs working with complex systems. Both are useful and respectable jobs but you both want an individual who can actually do it, not someone who just thinks they can, and someone whose capabilities won't be wasted on too simple tasks. These tests are great tools to help you figure out future performances of said individuals, as well as their satisfaction on the job/task. A mismatch will cause impact both for the individual and the company/military unit/etc.

The US Army requires a minimum AFQT percentile of 31 for enlistment which, based on standard IQ norms (mean = 100, SD = 15), maps to roughly an IQ of 85 (one standard deviation below mean).

I.e. if you have an IQ below 85 you can't even sweep up the floor for the army

And it’s because they found that using people below that threshold for _any purpose, including canon fodder_ has disastrously bad outcomes.

I mean, a quick look at the flynn effect would indicate that's complete fucking nonsense.

we won ww2 with an army a solid SD below today's 100.

Well the flynn effect is global so either the russians won ww2 with people an SD below today's mean IQ or the US military thinks that the russian army (that won ww2) circa '40 wasn't even fit for cannon fodder.

Flynn effect operates on the assumption that intelligence is a valid and measurable metric, while you previously argued it was not. You selectively do believe in when it affirms your bias? Nice one. You think you know more about this than experts who study it. I see. That's enough of you lol.

No, the Flynn Effect is an observation that raw scores on "IQ tests" have increased over (a far too short period to be attributable to evolution) time and/but IQ is defined as having a median value of 100 . It is not an assumption that intelligence is a measurable metric (redundant) it is an observation that the metric is a shit metric -- particularly over time. It is explicitly a point against "IQ" as a valid and measurable metric.

So now you're pivoting to saying Flynn Effect is just an observation of noise and human error with no meaning. You brought up the Flynn Effect, but you don't think it's meaningful to measure IQ? But you do think time series analysis on IQ is meaningful? You made no attempt at even a reasoned claim that Flynn Effect debunks validity of IQ. It's all patchwork emo stuff going on with u, and u agree grammur policing is a last resort of a broken mind. Not much respond to when you have to twist yourself in a pretzel and then trip over your own arguments on the pivot.
