I finally got the nerve to watch this. Morris started off saying they haven't said much about higher education since the 2005 article. To be fair, he said they didn't talk about is as in-depth as that article. However, I mapped the frequency which the phrase "higher education" is found in The Watchtower since 1950. I only counted number of articles the phrase was found in, not the number of times the phrase is actually used. The 2005 article uses the phrase 16 times in a single article. Results are quite telling.
1950-1959 - 5 articles
1960-1969 - 8 articles
1970-1979 - 7 articles
1980-1989 - 18 articles
1990-1999 - 13 articles
2000-2009 - 13 articles
