Jason Richwine's Resignation Is Welcome News, But We Expect More

Commented May 17, 2013 at 06:26:42 in Latino Voices

“Well, I regularly serve in PhD thesis committees at multiple institutions, including Ivy league universities in departments where science matters.
Again, for your education: Science is about your peers!! If your work cannot be reproduced or validated by your peers, it should be retracted!!
as a faculty and a PhD myself, I have all the right to review this dissertation and point to the multiple flaws in the design and methodology.
You are the one who clearly has no idea of how academia works and obviously do not have a PhD (unless you also bought it from the Kennedy School of Governement with money from American Enterprise).”

“Again, there NOT facts backed up by Richwine in his dissertation. This work should have never been approved by his thesis committee. Not because what it concludes, but because the design is a disaster.
And reading some comments below shows the need to improve how we teach Science in our schools. It is demoralizing that some people claim that some undefined results in a remote high school could be representative of the entire Asian and Hispanic population in the country. Or others equating national poverty with the intelligence of the citizens of that nation. And I was surprised when some states put creationism at the same level as evolution...”

“His dissertation was poorly cited. It also uses too many secondary sources. However, outrage over his methodology is a red herring. They dislike the content, that is their primary objection. Look at the Bell Curve, that book was well researched, and well cited. Did that stop the book from being demonized? No, it did not.”

“Have any specific reasons why we should believe you know more about the subject than the Harvard professors that approved his dissertation? Otherwise I think it fair to say you don't know what you're talking about.”

“Science is validated through peer-review. A thesis without a single publication is prsufficient proof for an abject failure.
In addition, many technical issues, obvious for any researcher with a minimal experience with the use of statistical analysis, make this work and its conclusions invalid and um worth of a PhD degree. The most obvious is the arbitrary selection of data sets, which do not represent the population under study.
I have enunciated a few,bmore,ut there are many.
If Harvard cared about its reputation, there would be an independent investigation, lead by statisticians outside Harvard, to judge the validity of this analysis.
Because extrapolating conclusions to millions of people and the need for specific policies should have legal consequences, if your study is based on bigotry and not supported by a rigorous design.I would not expect to call your children dumb without solid proof and get away with that.”

“Science is about rigorous and reproducible methodology. Again, to claim that "Hispanics" have lower IQs, and that this is a measurement of intelligence, you need a study group that reflects the "Hispanic" population as a whole, as well as proper controls and tests that are adjusted to different cultural and socioeconomic backgrounds and measure "intelligence". That's not the case and therefore this work would have been trashed by any minimally knowledgeable peer in a decent review process.
Lack of scientific rigor in the biomedical field, for instance, has legal consequences.
All my criticisms and questions remained unaddressed, but I would be happy to get your figures on the average IQ scores of "native whites" in socioeconomic and geographical settings similar to those where the scores were obtained for "Hispanics".
And it is sad that Harvard refuses to discuss this issue at an academic level, because an independent investigation by qualified statisticians would invalidate the study and its conclusions.”

“It depends on the Hispanic group. Chileans and Argentinians have higher IQs as they are more White than Mexicans. Mexicans that are predominantly Spanish have higher IQs than Mexicans that are more American Indian.

The studies have been consistent with over 100 years to prove that at this point. Racial IQ differences are not in dispute, only the cause.”

“We could look to Steve Sailors work where he points out there are more woman& male donkey shows in Mexico than libraries and book stores. Along with a dearth of Spanish language bookstores everywhere but Spain.”

“At Lincoln High School in Los Angeles both the Asian students and the Hispanic students live in the same surrounding neighborhoods, earn similar family incomes (”

“Additional comments:

-How these results compare to those from “whites” in Southern states, where IQ scores are significantly lower?

-The study uses a variety of datasets. Do they have a similar distribution? If so, whether they can have the same weight in the study is not explained.

-Statistical analysis is poor and P values are not shown for multiple critical readouts.

-The distribution of cultural, linguistic and socio-economic backgrounds of the individuals who took the test are not considered, so that absolute numbers cannot be compared across different distributions, because these environmental circumstances, which can change in 1-2 generations, clearly impact IQ scores.

-How were IQ tests administered, how they were modified to reflect different cultural/linguistic backgrounds potentially affecting scores is not properly discussed.

-The limitations of the IQ test and the fact that it was designed to predict success in modern academic training and not necessary “intelligence” are improperly discussed.

-The assumption that grandchildren of current immigrants will not reach parity with other races regardless of how their socioeconomic circumstances may change in the future (which is unpredictable at the time) are not (and cannot be) supported by empiric data.”

“Explain why 4th generation Hispanics in the US are far behind 1st generation Asians whose parents got off a boat with nothing. Of course east Asians evolved under the same conditions as Europeans, and are the only other people to create civilizations”

“Racial and ethnic group IQ scores in Southern state match those in other states. As a result, states with large African American and Hispanic population rank low while less diverse states rank high. New Hampshire, which has 92% non-Hispanic white, tops the state IQ list while Mississippi, which is 57% non-Hispanic white, ranks last. New Mexico, which is 46% Hispanic, ranks next to last. Racial and ethnic demographics determine state IQ rankings.

Differences in mean IQ scores between racial groups in the United States are well-documented and not subject to much dispute. You evidently have read Richwine's dissertation. He supports his contention that current immirtants may not reach parity in the near future by predsenting data showing IQ progressions in previous gfenerations of immigrants.”

“Thanks CD0, That's how you properly conduct a research, I'm pretty sure he doesn't have an answer for most of those questions. There's 21 Spanish speaking countries, how could he had possibly gone through through all all of them and such a little time frame.”

“I have read the dissertation and I found multiple technical and conceptual mistakes that make this work clearly unworthy of a PhD degree. I tried to contact the members of his thesis committee but so far I got no response. Some examples:

-I could not find a single peer-reviewed publication derived from these studies in any public database.

-There is no information on how representative datasets used are of the immigrant population in the US as a whole. It is clear that the author did not generate his own dataset with properly selected cases vs. controls. If the data are not representative of the entire Hispanic population (e.g., same socio-economic distribution, representative countries of origin, etc), the conclusions cannot be extrapolated to the Hispanic population as a whole and therefore the implications of the results, as presented, are bogus.

-Another important issue ignored in the dissertation is the improper definition of “Hispanic”, which involves virtually every race, including predominant populations of European origin in countries such as Chile or Argentina. This potentially confounding factor was not considered. Do “whites” of Hispanic origin who took the IQ test performed similarly to Hispanics of other racial groups? If so, the implications of inheritance should be much better justified.

-The motivation of the individuals who took IQ tests in different settings (e.g., public inner city vs. suburban private schools) is not considered. Did “whites” in the same setting achieved comparable, better or worse scores?”

“Just because you couldn't find the references in a public database does not invalidate the study.”
