The president of a women's university on Monday lashed out at a song written by Yasushi Akimoto, mastermind of the all-girl idol group AKB48, that says it is OK for girls to be "empty-headed" and that being intelligent is "meaningless" if one is "not loved."

"I felt as if the clock had been turned back to 50 or 100 years ago," Masami Ohinata, a psychologist who is president of Keisen University in Tokyo, blogged after a student showed her the lyrics.

"Einstein yori Dianna Agron," was released on April 13 by HKT48 in Fukuoka, one of the idol group's many regional sister units.
