The nature versus nurture debate is a longstanding dispute among philosophers and psychologists, but a new study on math aptitude seems to indicate that skill in that subject area is unrelated to gender. While boys outperform girls on a math test given to children around the world, the gap is less pronounced in more gender-neutral societies, where women are afforded the same rights and opportunities as men. Of the 40 countries studied, Iceland was the only one in which girls scored higher in math than boys. The study does not explain why girls in Germany, a country in which gender equality exists, continue to perform more poorly in math than boys.
