Must, Olev; Must, Aasa; Raudik, Vilve – Intelligence, 2003
Investigated the secular rise in IQ scores over 60 years in 12-to-14-year-old Estonian students using data from the 1930s for 307 students and data from 1997-1998 for 381 students. Results indicate that the secular rise is not occurring on the "g" factor. (SLD)
