They also said it is a clear rebuttal to Larry Summers, who as president of Harvard University said in 2005 that biological differences could explain why fewer women became professors of mathematics. Summers is now chairman of the Council of Economic Advisers for President Barack Obama.

"We conclude that gender inequality, not lack of innate ability or 'intrinsic aptitude', is the primary reason fewer females than males are identified as excelling in mathematics performance in most countries, including the United States," Janet Hyde and Janet Mertz of the University of Wisconsin in Madison wrote in their report.
