I can't find any evidence that he published this study. 
@Russwarne Apparently Jensen did a textbook study in 1969. Maybe relevant if you're planning any follow ups. http://arthurjensen.net/wp-content/uploads/2014/06/Reducing-the-Heredity-Environment-Uncertainty-A-Reply-1969-by-Arthur-Robert-Jensen.pdf …pic.twitter.com/BwMWGJUvBv

@gwern did you come across anything related to this in freeing up the Jensen literature? -
Doesn't ring any bells. Checking the missing post-1969 papers/chapters, none of the titles look particularly relevant in the next few years.

One day we will have to fly down to the Jensen archive and see what we can find.
