Heritage scholar resigns over past criticism of 'low-IQ' Hispanics

A Heritage Foundation scholar has resigned after a firestorm erupted over his 2009 dissertation alleging Hispanics do not have “IQ parity with whites” and that Hispanic immigrants to the United States will have “low-IQ children and grandchildren.” 

"Jason Richwine let us know he's decided to resign from his position," the conservative think tank said in a statement. "He's no longer employed by Heritage."

Richwine’s Harvard University dissertation, written before his employment at Heritage, asserted that an influx of "low-IQ" immigrants coming to the country would result in “a lack of socioeconomic assimilation among low-IQ immigrant groups, more underclass behavior, less social trust, and an increase in the proportion of unskilled workers in the American labor market."

"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," Richwine wrote.

The dissertation, first reported by the Washington Post, was particularly explosive because of Richwine’s role in co-authoring a major Heritage Foundation report – released Monday - on the cost of comprehensive immigration reform. 

That report, which was widely criticized by pro-reform Republicans for failing to take into account immigrants' contributions to the economy, estimated that the cost of allowing undocumented immigrants a path to citizenship would top $6 trillion. 

Heritage Foundation spokesman Michael Gonzalez said earlier this week that Richwine "did not shape the methodology or the policy recommendations" in the cost report released this week and that he provided only "quantitative support" to lead author Robert Rector. 

The dissertation's findings, Gonzalez said,  "in no way reflect the positions of The Heritage Foundation."
