Transcript for 'Tiger Mom' Returns
Tonight here, she calls herself the tiger mom. Her first book caused a fire storm. No play dates, no sleepovers, nothing less than an "a." Tonight, she's adding more, arguing why certain groups make it in america. Abc's aditi roy tonight. Reporter: The self-described tigre mom is back. Author amy chua, whose tough-love parenting techniques described in her 2011 book sparked uproar among some parents, has just co-authored a new book with her husband, jed rubenfeld, that could cause even more outrage. In, "the triple package," the authors claim these eight cultural groups in the u.S. Are more successful than others. Among the eight? Jewish, indian, chinese and iranian. The reason? Chua and her husband argue the groups balance three factors -- superiority complex, insecurity, and impulse control better than others do. And these traits contribute to their success. Chua, a yale law professor, has battled controversy before. I think sometimes that some parents give up too quickly. Reporter: In her 2011 book, "the battle hymn of the tiger mother," chua described her strict parenting approach, that some called cruel. No play dates, no sleepovers, no bathroom breaks during piano practice and no grades below "a." My daughter lu lu came back with a bad math test when she was about 10. And she said, "i hate math, I'm bad at math." I didn't accept that. Reporter: Chua responded to her critics of her first book during an interview with abc's juju chang. And so, in the end, tiger parenting is about pushing your child to live up to their potential? Yes, but always with love. I think that's the crucial thing. It's got to be high expectations coupled with love and listening. Reporter: In "the triple package," the authors claim to use, quote, groundbreaking original research and startling statistics, adding they hope readers will better understand why certain individuals and groups succeed and others do not. David? Thank you, aditi. A lot of opinions on this one. Send us a tweet.
