Research Analysis
Author and homeschool researcher Milton Gaither writes: “This new study tries very hard to overcome one of the most persistent deficiencies of his [Brian Ray's] previous work (and the 1999 Rudner study)–the near exclusive reliance on HSLDA’s advertisement to recruit subjects, leading to unrepresentative samples. This time around Ray tried to recruit families from outside of the HSLDA orbit. Did he succeed? Not really.”
