Researchers from the University of Canterbury interviewed hundreds of 13-year-olds about their attitudes toward PE and maths and found that, while most male students enjoy PE, boys who are Maori, Pasifika or Pakeha and from poorer backgrounds are much more likely to assume they will go into physically-demanding careers, even when they excelled in maths.
Meanwhile, Pakeha boys from richer backgrounds are substantially more likely to aspire to careers in law or medicine.
David Pomery from the University of Canterbury did the study. He spoke to Corin Dann.
