Unwise and wrong to mention low average Hispanic IQ?

Ruben Navarrette (writing below) is a somewhat conservative Hispanic journalist but there are some truths he can't stand.  He is almost certainly right  in saying that Republicans should avoid the issue of Hispanic IQ but he then goes on to say that Richwine's research is "discredited".  It is anything but.  It was endorsed by three eminent experts in the field.  Ruben appears to have mistaken Leftist disapproval for scientific evidence!  Dumb, Ruben, dumb

Dear Heritage Foundation, you're not helping.

I assume you agree with the proposition that -- demographics being what they are -- it would be a good thing to thaw out the frosty relationship between Latinos and Republicans. Yet, your incompetence and insensitivity during the Jason Richwine debacle have brought in a new cold front.

What's the point of building bridges between Latinos and the Republican Party if one of the nation's leading conservative think tanks is going to blow them up?

Frankly, I couldn't care less if Latinos never cast another vote for a Republican candidate.

Here's what I do care about -- that Latino voters see casting such a vote as a viable option. I want Latinos to have choices and be courted by both parties. Otherwise, they will be politically irrelevant, written off by one party and taken for granted by another. Competition keeps people on their toes.

That's the collateral damage of L'Affaire Richwine. Here's the background: Jason Richwine is a former senior policy analyst at Heritage and the co-author of a roundly discredited study that said the Senate immigration reform bill would cost taxpayers roughly $6.3 trillion over the next half-century. It was recently revealed that Richwine -- in his 2009 Ph.D. dissertation at Harvard's Kennedy School of Government -- made the goofy argument that Hispanic immigrants and their descendants were forever destined to be less intelligent than whites. He wrote:

"Immigrants living in the U.S. today do not have the same level of cognitive ability as natives. ... No one knows whether Hispanics will ever reach IQ parity with whites, but the prediction that new Hispanic immigrants will have low-IQ children and grandchildren is difficult to argue against."

The poor performance on IQ tests by blacks and Hispanics is exactly what one would predict given their substandard achievements.  The test  performance of blacks and Hispanics validates the tests.  The test results  predict that these groups will have poor educational, vocational and financial success.  And they do!  The tests provide correct predictions.  If blacks and Hispanics did just as well in education and in the workforce as whites do, THEN the tests would be "discredited"
