Over at his blog, Tom Tritton revisits a paper published in Science in July that examined whether boys are better at math than girls, finding that the groups are equally capable. "Smaller studies from the 1970s and 1980s seemed to suggest somewhat inferior math performance of females, especially in high school. The new data, though, find no such difference," he writes at Periodic Table. The reasons, though, for women missing in action from the top spots in math and science are still being pondered, but at least "we do know it’s not because of any significant difference in ability."
