I am in a business college.

shocker, there.

Yes, gottfredson is so clever, she pulled one over on all them stoopid congress peoples and advanced her racist agenda under their noses. We are all celebrating now because of the glass ceiling.

I think studying ECTs is de facto research on causality.

The case was in 1971. After the ruling you cite, what did every company with half a brain do: Throw out their IQ tests. Academics / college professors then started studying it in exhaustive depth. In the decades after Griggs the validity data became so massive that the civil rights act was amended. The surreal irony here is that Linda Gottfredson actually played small role in this!

Yes, and I don’t doubt she did – what you have usefully confirmed (thank-you very much) is how much of your “decades” worth of “validity data” has simply been gathered in the service of spin.

I have carefully read your comments and your paper and this is all you have come up with so far.
1. Correlation: IQ test performance and Job performance (ie – being good at performing is a portable skill)
2. Correlation: IQ test performance and speed performance (ie – being good at tests is a portable skill)
3. Correlation: IQ test (+other test) performance and self-defined socially constructed “racial identities” [which you falsely persist in conflating with "race," and thence, with notional discrete genetic populations] (ie – people who have grown up knowing themselves to be expected to perform poorly often fulfill such expectations in various test and performance conditions).

Such “correlations” are the sum total of what you’ve got. Enough for a bit of creative spin when lobbying lawmakers, or providing “expert” testimony in court, but not enough in themselves to be either interesting, or to add new and useful knowledge to the social sciences.

You have not shown one ounce of interest in pursuing the meaning of such correlations. As every epidemiologist knows, establishing a correlation is only the beginning of your work. You can document a correlation until the cows come home, but if all you have is a correlation, you’ve got nothing. Correlations may be artifacts, or they may be real. If real, they may result from further, as yet undiscovered causes.

You have shown no interest in precision in your definition of “race”. Someone’s selection of an identity off of a list of predetermined choices may have little or no demonstrable bearing on their genetic similarity or difference to people who have made different selections on that same list.

Bryan, you are a spin doctor – possibly a good one. But you are not a scientist, and your work is not science – it is marketing.

Even worse, polygraphy has been shown inadequate and inaccurate in many studies and is still being used in trials.

Polygraphs are pseudoscientific and used during investigations, whether criminal or background checks, to coerce or trick innocent people into confessing. They should be banned, not praised. I once refused a job interview because they wanted a polygraph test, after having been false positive on a polygraph test in a criminal matter. I told the potential employer I had been bonded, and no claim had ever been filed against me.

As has been mentioned: you can set up a blog for free.

What bothered congress was the idea of race norming (and banding; now illegal, but very popular last century). Here’s the idea: Wow, this 12 minute test has incredible utility and validity. Fuck, it creates adverse impact. We can defend that legally, but I don’t want to spend 6 figures in court proving I am right, nor do I want to use a test that adversely affects my company’s diversity.

Solution: Add 15 points to black applicants scores. This removes the race difference, but then lets the company benefit from IQ tests without being sued!

Problem: Congress changed the civil rights act to make this illegal!

There was a high profile case last year where a content valid test was given to promote fire fighters (this is currently a massive problem in personnel psych. No one can create a test of anything mental that doesn’t measure g, so no one can create an employment test w/o also creating adverse impact). As the test was a mental test, it was g-loaded and showed race differences.

20 or so people scored high enough for promotion. IIRC, 18 were white 2 were hispanic, none were black.

The city threw the test scores out and didn’t promote these people. Law suits ensued, and the supreme court ruled the city was wrong.

That’s extreme, if mental tests are biased crap.

Let’s study it. Let’s not dismiss people who do as cranks just because they think the topic is of fundamental importance.

The manhole cover question was famous at Microsoft. Supposedly it was Gates’ idea as his philosophy was to hire smart people above any other quality. He did an ok job growing his company on this philosophy.

My point would be why ask a stupid question like this when you can give an IQ test instead?

Google is also famous for this. If I recall the had a bill board with a math puzzle on it. Being able to solve it led you to a web site where they then invited you to apply for a job.

I did cite somewhere the classic meta analysis on what predicts job performance. Believe it or not, experience is not as good as the 12 minute IQ test.

I also strongly agree that most employers’ interviews are wholly invalid.

I hear google too has grown nicely as a company.

Finally, my comment was only about federal judges– especially SCOTUS. I think their writings are often as beautiful as many things in classical literature (read the decision and dissent in steel workers v. weber, 1979– the case legalizing affirmative action in employment settings. I wish I could write so well:(
